Power monitoring!

Fri Jan 09, 2009 10:15 am

Anyone interested in some real good graphing of MT? I'm asking, because if there is a real demand, I'm more than happy to get these scripts on the WIKI, or even better (normis, PM me please), get this incororated into a MT Package perhaps. The stuff is relatively simple, so it should be quick.

So far, I monitor routing tables:
Image

Wireless Status (CPE Side):
Image

CPU Usage:
Image

Disk Usage:
Image

Memory Usage:
Image

Radius Client Stats:
Image

Adding scripts is relatively easy, I'm still going to add some more stuff (including scripts to monitor various things from /wireless registration-table), but if there's any specific requirements or graphs that some of you would like to see, feel free to mention them and I'll see whether it can be coded and included in the wiki pages to follow shortly hopefully....
Regards,
Chris

If this refers to Cacti graphs, it would be nice to have:
Number of PPPoE clients Connected
Number of Wireless Clients Connected per radio
Thanks :)

these aren't cacti :) you don't get these values via SNMP (Not all of them anyways)....

how do you get these values, and generate the graphs?

SSH/Telnet and the graphing engine is something called Munin normis (based on perl, VERY easy to convert into sh / bash / even c++). If we can get munin-node converted to not use perl and run it on MT as a package, then no requirement for Telnet/SSH connections to the router.

Scripts, are as easy and simple as daylight. Hence the first post Normis... Can we make a package?? :P :) :P :) You can graph anything you can dream off in a matter of 5 minutes....

Chris

Done. Not only do we graph PPPoE, we monitor total ppp connections and associate them with the different types of services too :) Unfortunately I don't really use PPP, so I can't get a sample graph going, but it is working...

Wireless stats are already in with the /wireless registration-table graph I'm making.

Indeed!

Munin operates on a monitoring server -> monitoring node principal. We can integrate a node into MT (it's INSANELY small), and even make the scripts customisable. You upload your scripts to the router for what you want to monitor, the server polls the node, and generate the graphs. What you want, when you want, how you want....

It's painless to do these probes.

I'm doing the /wireless registration-table graph now, I'll post the graph once it's finished - they should update in real time :lol:

Chris

Will dynamically configure the graph and add a line for every client in the registration table :)

everything that is needed to integrate it into RouterOS is too big combined, we can't do it. If possible, please make a detailed manual on the wiki on how people can use it in other ways

Normis - Granted, I still need to look at this, but http://sourceforge.net/projects/muninlite/ Munin Lite is the munin-node engine (the one that needs to be on the MT for best use), that runs as a bash script! It naturally fires off via inetd or xinetd, it already includes *some* scripts, and adding more scripts is a simple bash/sh script (it is not required that it must be perl, I use perl as my language of choice). There is also http://munin.projects.linpro.no/wiki/OpenWRT-HowTo operating on perlminimal, but granted, I understand you cannot slap perl on a MT :)

I don't know the inner workings, but if inetd isn't available either... I'm busy writing the WIKI page now. Having hundreds of logins on your router every 5 minutes just isn't ideal either (every script will login twice - once for a config, and once for getting values)...

Chris

like bad scripts do =) maybe it needs to be rewritten for one login per cycle? ;)

Not quite...

The graphs are based on RRD - it does a config in order to get a list of (and parameters) of the datastores that needs to be configured in the RRD Database. Therefore, it is possible to automatically add and remove data from graphs dynamically. In the case that where I monitor the registration table for example, it will do a config, see that there is two entries, and then automatically create a RRD for the 2nd entry in the registration table. Then go, and fetch the values thereof.

Granted, it would be fantastic if munin can do this in one connection, but it does not unfortunately.

Not all scripts require two logins however (radius stats is static for example, and mem/cpu uses SNMP), but untill munin-node runs on MT itself, it will be a downpoint of it yes. If the node is on the MT, you more than likely wont even notice the connection, as is the case of SNMP.

Chris

also, there is perl example of use of API, maybe this is way to go? it is not encrypted, but you won't be pulling passwords for graphs, would you? and for login there is simple chap challenge.

The API may be a way to go instead of Telnet/SSH yes, I haven't really played with it yet.

Will look into it at some stage, I just want to get everything on the WIKI for now, let's call the API version 2 :lol: Cherry on the cake would still be to have this on MT itself... It can't be that hard to execute a shell script to service a incoming connection???

While this stuff looks awesome, I would still like to see all of the information that is available in the registration table be available through snmp. It would allow us to make many more cool graphs like these. Not just the registration table, but it would be a good place to start..

Pleeeeeeeeeeeaaaasssssssee!

Re: Power monitoring!

Fri May 29, 2009 11:18 am

I need it for wireless signal graphing.
I installed it using wiki manual:
http://wiki.mikrotik.com/wiki/Munin_Monitoring

1.I put this in /etc/munin/munin.conf

[192.168.1.1]
address 127.0.0.1


I changed [node1.somewhere.com] for IP address of mikrotik I want to get info from(192.168.1.1).

2. PERL srcipt: mikrotikcpu_node1.somewhere.com I saved as mikrotikcpu_192.168.1.1
3. I changed the rights:
    $ chmod u+x /etc/munin/plugins/mikrotikcpu_192.168.1.1
    $ chown munin:munin /etc/munin/plugins/mikrotikcpu_192.168.1.1
    $ /etc/munin/plugins/mikrotikcpu_192.168.1.1

4. I restarted munin-node:
$ /etc/init.d/munin-node restart

5. connecting using tellnet shows that connection has closed:
    r-c@rclr-srv:~$ telnet localhost 4949
    Trying 127.0.0.1...
    Connected to localhost.
    Escape character is '^]'.
    # munin node at rclr-srv
    Connection closed by foreign host.
Can you help what I am doing wrong, propably names of that nodes, or?
Thanks.

In munin-node.conf, did you modify the ACL correctly?

Look for the allow lines

Propably I made mistake in /etc/munin/munin.conf
[192.168.1.1]
address 127.0.0.1
should be liked this:
 [192.168.1.1]
address 192.168.1.1
then I tryed:

r-c@rclr-srv:~$ sudo /etc/munin/plugins/mikrotikcpu_192.168.1.1 config
host_name 192.168.1.1
graph_args -l 0 -r --vertical-label percent --lower-limit 0 --upper-limit 100
graph_title CPU usage
graph_category system
graph_info This graph shows the router's CPU usage.
graph_order Total
graph_vlabel %
graph_scale no
Total.label CPU Usage
Total.draw AREA
Total.warning 60
Total.critical 90
That seems good.

Then I tryed:
r-c@rclr-srv:~$ telnet localhost 4949
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
# munin node at rclr-srv
Connection closed by foreign host.
and in apache, only shows name: 192.168.1.1, nothing more, no graphs(only graphs for local machine 127.0.0.1)

This i filled in /etc/munin/munin.conf:
[192.168.1.1]
    address 192.168.1.1
    use_node_name yes
and in /etc/munin/munin-node.conf
# Which port to bind to;
#host *
host 127.0.0.1
user root
group root
setsid yes

I dont now what I am doing wrong.

munin-node.conf

# doesn't understand CIDR-style network notation.  You may repeat
# the allow line as many times as you'd like
allow ^127\.0\.0\.1$
As I mentioned, you do not have the allow lines. Munin is rejecting the connection to 127.0.0.1 (your telnet) because it is not authorised to connect

Re: Power monitoring!

Fri Jun 05, 2009 2:11 am

OK... pulling my hair out on this one. I've tried a few different settings. I can't get them to show up as a node, followed wiki exactly.

Just as my contemporary, radocicala I...

1. changed [node1.somewhere.com] for IP address of mikrotik I want to get info from(10.1.30.1).

2. PERL srcipt: mikrotikcpu_node1.somewhere.com I saved as mikrotikcpu_10.1.30.1

3. I changed the rights:
Code:
$ chmod u+x /etc/munin/plugins/mikrotikcpu_10.1.30.1
$ chown munin:munin /etc/munin/plugins/mikrotikcpu_10.1.30.1

4. Tested it:
sudo /etc/munin/plugins/mikrotikcpu_10.1.30.1 config
host_name 10.1.30.1
graph_args -l 0 -r --vertical-label percent --lower-limit 0 --upper-limit 100
graph_title CPU usage
graph_category system
graph_info This graph shows the router's CPU usage.
graph_order Total
graph_vlabel %
graph_scale no
Total.label CPU Usage
Total.draw AREA
Total.warning 60
Total.critical 90
**@WW-LINUX-01:/etc/munin/plugins$
5. I restarted munin-node:
sudo /etc/init.d/munin-node restart
BECAUSE OF ---->>>
The address, will always be pointing to 127.0.0.1 as Munin needs to connect to our only real munin-node we have running on localhost.

I kept the "address 127.0.0.1" instead of changing this part to 10.1.30.1 (But I tried both ways)


When I try to show the node that I had just made I got the following......
(ONLY LISTING "localhost" not any other)
telnet 127.0.0.1 4949
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
# munin node at localhost

.
quit

BUT! I did happen to type "list" and low and behold, there sits "10.1.30.1" in the list... hell if I know why....

FOUND IT! :)
ok.. I couldn't figure out the whole file color thing inside the /etc/munin/plugins/ directory. All the other flies were cyan where the file that we were directed to create was green after investigating why this was I did a ls -l , and after looking at it a few dozen times realized that ALL the scripts in the /etc/munin/plugins/ directory were links to the REAL file in /usr/share/munin/plugins/ directory.

Update needed for wiki

Make link:
sudo link /etc/munin/plugins/mikrotikcpu_node1.somewhere.com /usr/share/munin/plugins/mikrotikcpu_node1.somewhere.com
THEN restart munin
sudo /etc/init.d/munin-node restart
Check munin (in telnet)
telnet 127.0.0.1 4949
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
# munin node at localhost
nodes
10.1.30.1
localhost
.
quit
Connection closed by foreign host.
and low and behold there sits my router!

Anyone wanna confirm this?

Thanks,

Josh

****EDIT****
False alarm... musta changed something else... it only showed up on the graph for a minute, when I restarted munin.conf the next time - NO VA

Fantastic. I've got all three of the SNMP scripts set up and working like a charm:
cpu.png
diskspace.png
memory.png
The only thing I can't get my head around is how munin-node knows which plugins to run against which node. For example, I have the following:
# telnet 127.0.0.1 4949
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
# munin node at XXXX.vitell.co.uk
nodes
181.87.193.10
xxxx.vitell.co.uk
.
quit
Connection closed by foreign host.
all the plugins are in the same directory (/etc/munin/plugins) and yet:
# telnet 127.0.0.1 4949
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
# munin node at xxxx.vitell.co.uk
list 181.87.193.10
mikrotikcpu_181.87.193.10 mikrotikdiskspace_181.87.193.10 mikrotikmemory_181.87.193.10
list xxxx.vitell.co.uk
open_inodes apache_processes entropy apache_accesses processes apache_volume squid_cache df interrupts netstat swap load if_err_venet0 df_inode cpu if_venet0 forks open_files memory squid_requests squid_traffic vmstat
quit
Connection closed by foreign host.
it knows which plugins to apply to which host.

Now, I can understand how the mikrotik* plugins work as they define 'host name' when you run the 'mikrotikcpu_HOSTNAME config' script, but I just don't get how/why the standard 'apache_accesses' script runs against xxxx.vitell.co.uk but not 181.87.193.10.

Anyway, it works, so I guess I shouldn't be questioning things, I'd just like to know why it works!

With the mikrotikppp_HOST script:
Use of /g modifier is meaningless in split at
        /usr/lib/perl5/vendor_perl/5.8.8/Net/Telnet/Cisco.pm line 756 (#1)
    (W regexp) You used the /g modifier on the pattern for a split
    operator.  Since split always tries to match the pattern
    repeatedly, the /g has no effect.
After some digging, it appears that this is a known bug in some versions of Net::Telnet::Cisco. In my case, the CentOS supplied package (perl-Net-Telnet-Cisco) comes complete with this bug. In case anybody else has this problem, edit the file mentioned in the error message and change the line from "return wantarray ? split /$/mg, $_ : $_; # ORS instead?" to "return wantarray ? split /$/m, $_ : $_; # ORS instead?". How this affects other things I could not say, but given that I installed Net::Telnet::Cisco specifically for this purpose, it works fine for me.

Also, there is a bug in the script. Munin doesn't like a graph_vlabel with spaces in it. I replaced "# of connections" with "number" and it worked just fine. I have updated the wiki accordingly.

Interestingly (and apropos of my last post), I have four hosts being monitored from the one box:

MT_1
MT_2
localhost
remotehost

Whilst the mikrotikcpu (and diskspace and memory) plugins only work against the MT_x hosts, mikrotikppp works against MT_1, localhost and remotehost, but not MT_2. What gives?

More from me, I'm afraid...

I tried to get the 'mikrotikwirelessregistrations' code working and found that the comments preceding it were correct (it doesn't work!!), so I decided to write my own in PHP using the PHP API - http://wiki.mikrotik.com/wiki/API_PHP_class. The code is below and I'll tidy it up and post it on the wiki as and when somebody else tests it too!!
#!/usr/bin/php
<?php

// Use the ROS API.
require('routeros_api.class.php');

// Create a new instance
$API = new routeros_api();

// debug - true or false
$API->debug = false;

// First things first, get the information we want to look at
if ($API->connect('111.222.111.222', 'USER', 'PASS')) {

   $API->write('/interface/wireless/registration-table/getall');
   $ARRAY = $API->read();

   $API->disconnect();
} else {
  die("Unable to connect to API.");
}

// Work out the hostname to use based on the filename called
$hostname = explode("_",$argv[0],2);

// And die if there isn't one.
if (! isset($hostname[1])) {
  die("No hostname available");
}

// If the first argument is 'config', then do the config stuff.
if ($argc > 1 && $argv[1] == 'config') {
  printconfig($hostname[1]);
  if (!empty($ARRAY)) {
    foreach ($ARRAY as $value) {
      print $value["interface"] . ".label " . $value["interface"] . "\n";
    }
  }
  exit;
}

// Otherwise, display the values.
if (!empty($ARRAY)) {
  foreach ($ARRAY as $value) {
    $signal=explode("d",$value["signal-strength"],2);
    $signal=$signal[0];
    print $value["interface"] . ".value " . $signal . "\n";
  }
}
exit;

// Function which prints the information needed for 'config'.
function printconfig($hostname) {
        print "host_name $hostname\n";
        print "graph_args -l 0 --lower-limit -100 --upper-limit 0\n";
        print "graph_title Wireless Interface Registrations (Signal Strength)\n";
        print "graph_vlabel dBm Signal\n";
        print "graph_category network\n";
        print "graph_info This graph shows the wireless registration signal strength\n";
        print "graph_scale no\n";
}
?>
Now, can somebody explain why the graph shows
signal.png
even though the code returns:
/etc/munin/plugins/mikrotikwirelessregistrations_181.87.78.85
wlan2.value -84
wlan3.value -58
Because that's puzzling me!

Can you post what the output of mikrotikwirelessregistrations_181.87.78.85 config returns?

I doubt there is anything wrong - may just take a bit of time for the graph to 'seatle' down. /var/log/munin/* is also your friend.

And yes, its the same issue on FreeBSD too - the latest versions of Net::Telnet::Cisco is broken. Packaged versions seems to be a older version which still works. It's trivial to ammend the code to use Net::Telnet instead of Net::Telnet::Cisco though (just the Prompt regex needs to change afaik).

Chris

Known issue with newer versions of Net::Telnet::Cisco yes. Change it to use Net::Telnet and ammend the regex for the prompt acordingly. It works absolutely fine, i.e:
use Net::Telnet;
...
  my $Telnet = new Net::Telnet (Timeout => 10,
                                Prompt  => '/\[.+\] > $/');  # <-- NB Critical
  $Telnet->open($Data['2']);
  $Telnet->login(RLM_TELNET_USER . '+ct', RLM_TELNET_PASS);
  @Output = $Telnet->cmd("whatever");
...
Also, there is a bug in the script. Munin doesn't like a graph_vlabel with spaces in it. I replaced "# of connections" with "number" and it worked just fine. I have updated the wiki accordingly.
Thanks. I've noticed this a while ago, never got arround to updating it.
Interestingly (and apropos of my last post), I have four hosts being monitored from the one box:

MT_1
MT_2
localhost
remotehost

Whilst the mikrotikcpu (and diskspace and memory) plugins only work against the MT_x hosts, mikrotikppp works against MT_1, localhost and remotehost, but not MT_2. What gives?
1) For some reason, these things don't always work when you have physical plugin commands. Best practises, use, and stick to, symlinks.
2) Ensure that everything works when Munin starts. When you start Munin-Node, it verifies all configured hosts, if it fails, it is marked as dead and won't ever become active
3) Have a look at the munin-node log files for possible errors, also perhaps bump up the logging levels in munin-node
4) No need to specify local host :)
4.1) The munin node where all the scripts run, will automatically monitor the host where it is being run on by itself (all the other scripts in the plugins directory)
4.2) munin uses the 'nodes' command to determine what other nodes it is configured for, i.e:
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
# munin node at fusion
nodes
WMEO01-CORE01
WMEO01-EDGE01
fusion
4.3) It then proceeds to do a 'list' command for itself, as well as all nodes. This tells munin which plugins to execute for which nodes, i.e:
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
# munin node at fusion
list fusion
open_inodes asterisk_channelstypes irqstats mysql_slowqueries if_eth0 apache_accesses squid_cache raid ntp_states mysql_threads apt df uptime swap load postfix_mailstats df_inode cpu mysql_queries open_files iostat forks asterisk_voicemail memory ntp_igubu_saix_net vmstat asterisk_channels asterisk_iaxchannels if_err_eth0 apache_processes entropy asterisk_iaxpeers postfix_mailqueue processes asterisk_iaxlag apache_volume ntp_queries metar_pressure asterisk_sipchannels netstat interrupts mysql_bytes asterisk_sippeers munin_graph metar_temp postfix_mailvolume munin_update asterisk_codecs squid_requests metar_wind squid_traffic ntp_induna_saix_net
Hope this helps a bit, and great work on the new plugins - we should stick them on the WIKI... I still feel this needs to be integrated inside MT however, shruglette...

Chris

Hmm,

Try setting the upper limit to 1? Might be something with munin that's not too intelligent.
root@fusion:/etc/munin/plugins# ./mikrotikwirelessinterface_WMEO01-EDGE01 config
host_name WMEO01-EDGE01
graph_args -l 0 --lower-limit -100 --upper-limit 100
graph_title Wireless Interface Quality (MACAddress)
graph_vlabel Comms Quality
graph_category network
graph_info This graph shows the wireless interface statistics
graph_order txccq rxccq txsignal txrate rxrate acttimeout noisefloor
graph_scale no
txccq.label TX CCQ (%)
rxccq.label RX CCQ (%)
txsignal.label TX Signal Strength (dBm)
acttimeout.label ACT Timeout (us)
noisefloor.label Noise Floor (dBm)
txrate.label TX Rate (Mbps)
rxrate.label RX Rate (Mbps)
works fine for negative numbers here...

Nope. Although the graph now has the correct scale, nothing's being plotted on it (I suspect that what's there is still positive and out of range of the graph.

Strange.

Munin (was: Re: Power monitoring!)

Tue Jun 23, 2009 9:38 pm

And another one - last one of the day!!

I have just added the code to allow graphing of packet volume matching certain firewall rules. If you want to graph the number of packets matching a rule, add a comment to the rule in the form "GRAPH - xxxxx" (where "xxxxx" is the label you want to give the data).

This allows you to easily add and remove data to be graphed just by changing the comment.

Note that this does not work on ROS 3.25 since the API no longer gives access to the comments field (I assume this is a bug and have reported it as such).

I'll leave it a day or so to allow some nice graphs to be produced, then I'll upload those examples to the wiki.

Right, I've updated the wiki with the graphs the three new plugins (the three at the bottom of the page):

http://wiki.mikrotik.com/wiki/Munin_Monitoring

I've spent a fair bit of time with this and it's certainly useful to me - is it useful to anybody else? Does anybody else have some ideas on what other useful information could be graphed?

Heh. I know what you mean. I just wrote it as an exercise to see what could be monitored and for no other reason. However, I found a use for it pretty much straight after I wrote it - I use ROS at home and share my Internet connection with my neighbours. Monitoring firewall rules makes it a piece of cake to graph bandwidth use by each of those neighbours. I simply add a rule which matches their traffic and which does nothing (passthrough). It doesn't give me absolute figures, but it does show me when they're hammering the connection and for how long.

That's not the monitoring i was pointing out:
Ah sorry. Mea Culpa. Well, the theory was that individual people could contribute firewall rules to various chains and that it may be useful to see when changes have been made. It's also handy to see when dynamic rules have been added/removed. Again, not a useful tool in itself, but it could provide a reasonable overview.

Sadly, in my experience, any number of small-ish companies who don't want to employ one person to look after their infrastructure and who shares the work out amongst a team of people.

I've been needing this for a long time. This way, I can finally change a router without losing the interface graphs (:

I have problem to install this using wiki manual, can anybody help:

My situation: ubuntu router(ip: 12.12.12.12)
mikrotik router ip: 192.168.1.1

I added virtual host like this to my /etc/apache2/apache2.conf:
<VirtualHost *:80>
        ServerAdmin webmaster@localhost
        ServerName monitor.example.com
        DocumentRoot /var/www/munin
        <Directory />
                Options FollowSymLinks
                AllowOverride None
        </Directory>
        CustomLog /var/log/apache2/monitor.example.com.access.log combined
        ErrorLog /var/log/apache2/monitor.example.com.error.log
        ServerSignature On
</VirtualHost>
munin.conf:
# Example configuration file for Munin, generated by 'make build'

# The next three variables specifies where the location of the RRD
# databases, the HTML output, and the logs, severally.  They all
# must be writable by the user running munin-cron.
dbdir   /var/lib/munin
htmldir /var/www/munin
logdir  /var/log/munin
rundir  /var/run/munin
tmpldir /etc/munin/templates

# Where to look for the HTML templates
tmpldir /etc/munin/templates

# Make graphs show values per minute instead of per second
#graph_period minute

# Graphics files are normaly generated by munin-graph, no matter if
# the graphs are used or not.  You can change this to
# on-demand-graphing by following the instructions in
# http://munin.projects.linpro.no/wiki/CgiHowto
#
#graph_strategy cgi

# Drop somejuser@fnord.comm and anotheruser@blibb.comm an email everytime
# something changes (OK -> WARNING, CRITICAL -> OK, etc)
#contact.someuser.command mail -s "Munin notification" somejuser@fnord.comm
#contact.anotheruser.command mail -s "Munin notification" anotheruser@blibb.comm

# For those with Nagios, the following might come in handy. In addition,
# the services must be defined in the Nagios server as well.
#contact.nagios.command /usr/sbin/send_nsca -H nagios.host.com -c /etc/send_nsca.cfg

# a simple host tree
[localhost]
    address 127.0.0.1
    use_node_name yes

# A more complex example of a host tree
#
## First our "normal" host.
# [fii.foo.com]
#       address foo
#
## Then our other host...
# [fay.foo.com]
#       address fay
#
## Then we want totals...
# [foo.com;Totals] #Force it into the "foo.com"-domain...
#       update no   # Tur#
#   # The graph "load1". We want to see the loads of both machines...
#   # "fii=fii.foo.com:load.load" means "label=machine:graph.field"
#       load1.graph_title Loads side by side
#       load1.graph_order fii=fii.foo.com:load.load fay=fay.foo.com:load.load
#
#   # The graph "load2". Now we want them stacked on top of each other.
#       load2.graph_title Loads on top of each other
#       load2.dummy_field.stack fii=fii.foo.com:load.load fay=fay.foo.com:load.load
#       load2.dummy_field.draw AREA # We want area instead the default LINE2.
#       load2.dummy_field.label dummy # This is needed. Silly, really.
#
#   # The graph "load3". Now we want them summarised into one field
#       load3.graph_title Loads summarised
#       load3.combined_loads.sum fii.foo.com:load.load fay.foo.com:load.load
#       load3.combined_loads.label Combined loads # Must be set, as this is
#                                                 # not a dummy field!
#
## ...and on a side note, I want them listen in another order (default is
## alphabetically)
#
# # Since [foo.com] would be interpreted as a host in the domain "com", we
# # specify that this is a domain by adding a semicolon.
# [foo.com;]
#       node_order Totals fii.foo.com fay.foo.com

I created: /etc/munin/plugins/mikrotikcpu_192.168.1.1 and put inside php text from wiki.
Then I: sudo /etc/munin/plugins/mikrotikcpu_192.168.1.1 config
host_name 192.168.1.1
graph_args -l 0 -r --vertical-label percent --lower-limit 0 --upper-limit 100
graph_title CPU usage
graph_category system
graph_info This graph shows the router's CPU usage.
graph_order Total
graph_vlabel %
graph_scale no
Total.label CPU Usage
Total.draw AREA
Total.warning 60
Total.critical 90
Then I:
$ telnet localhost 4949
Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
# munin node at localhost
Connection closed by foreign host.
Graphs for local pc are showing under: /12.12.12.12/munin, but graphs of mikrotik 192.168.1.1 dont show, can anybody help what is wrong with my configuration?

The problem was: I had to: sudo chmod -R a+rwx(i allowed it to run for all users), but you can limit it to user you want.

It shows me this error in mikrotikwirelessconnected template:
r-c@ubuntu-server:~$ sudo /etc/munin/plugins/mikrotikwirelessconnected_192.168.76.1 config

port 23: Connection refused
make sure you have telnet access to your router from that server

For every complex problem, there is a solution that is simple, neat, and wrong.
