Hello all!

I'have a lot of point of sale where we use the mikrotik routers. Some shops have dual WAN interfaces for failover by recursive routing. I want to monitor each of WAN interface thru ping to google DNS. How can i do that by dude?

In other words, it is necessary to start the ping from the device to 8.8.8.8

Why ping? What kind of wan connection do you have? In some cases you can monitor state (running or not) or count tx/rx packets in particular period of time.
When i was looking for the same probe (ping from different wans in device from dude) i didn't find. But if you want to ping, you can use not dude, but netwatch on device (add route to google DNS from particular wan and write script on down event)

Check if a certain program is running on a Windows system ('OUTLOOK.EXE' in this example):

Type: function
Available: if(array_find(oid_column("1.3.6.1.2.1.25.4.2.1.2"),"OUTLOOK.EXE")>0, 1, -1)
Error: if(array_find(oid_column("1.3.6.1.2.1.25.4.2.1.2"),"OUTLOOK.EXE")>0, "", "OUTLOOK.EXE not detected by SNMP probe")
Value: 1 (or anything else, is purely for charting purposes and I return 1 if the service is running)
Unit: running (or whatever you want to call the above values)
Rate: none

This of course requires the SNMP agent is running and configured properly on the Windows system.

This works great but is it possible to monitor if an application is in "Not responding" state?

Could it be that you use the wrong OID. I check Windows services as following:

Available: if(array_find(oid_column("1.3.6.1.2.1.25.4.2.1.2"), "db2sec.exe")>0, 1, -1)
Error: if(array_find(oid_column("1.3.6.1.2.1.25.4.2.1.2"), "db2sec.exe")>0, "", "DB2_db2sec.exe not detected by SNMP probe")
Value: 1
Unit: running
Rate: none

Change "db2sec.exe" with the name of the service you like to monitor. One thing I also noticed is, that the name is case-sensitive! Write the service name the same as you see it in the Windows Task Manager.

Sometimes it also helps to use the if() function for debugging. If you are not shure what you will get with "if(array_find(oid_column("1.3.6.1.2.1.25.4.2.1.2"), "db2sec.exe")>0" and want to see it, put the same command as "to do". For example:

Error: if(array_find(oid_column("1.3.6.1.2.1.25.4.2.1.2"), "db2sec.exe")>0, array_find(oid_column("1.3.6.1.2.1.25.4.2.1.2"), "db2sec.exe"), array_find(oid_column("1.3.6.1.2.1.25.4.2.1.2"), "db2sec.exe"))

With this error line you will see the output of the command in the "Problem" column of the "Services" table. Sometimes it helps me a lot to find bugs in my commands.

Hi
i've a question about function array_find !
i've integrate in the device appareance a count for process running (in my case HTTPD naming httpd.exe
my code
[array_element(oid_column("1.3.6.1.2.1.25.4.2.1.2"), array_find(oid_column("1.3.6.1.2.1.25.4.2.1.2"),"httpd.exe"))]
[array_find(oid_column("1.3.6.1.2.1.25.4.2.1.2"),"httpd.exe")]

the prolem il : i've 2 httpd.exe running (look with process explorer) and i watch on device 12 process ! !
it's a syntax function problem or bug on Dude program (version 4 running on windows server)

Hello, everyone!

I'm trying to setup HP Procurve Cpu probe from the following post.

Now I have configured:
Function
Name: Procurve_Cpu
Code: oid("1.3.6.1.4.1.11.2.14.11.5.1.9.6.1.0")

Probe
Name: Procurve_Cpu
Type: Function
Available: Procurve_Cpu() <> ""
Error: if(Procurve_Cpu() > 80, "", concatenate("Cpu load is = ", Procurve_Cpu(), "%"))
Value: Procurve_Cpu()
Unit: %

It seems that it working, but I need some advises:
1. I periodically get "Not available" - how this may be fixed?
2. Should I use Procurve_Cpu() > 80 or Procurve_Cpu() < 80 for Error? I need a notification when Cpu load is over 80%.
With current setup I get periodically errors: Cpu load is = 0%, Cpu load is = 4%
3. I also tried to configure something like this but without success - I got the error: parse failed

Function
Name: Procurve_Cpu_Test
Code: if(oid("1.3.6.1.4.1.11.2.14.11.5.1.9.6.1.0",10,5), oid("1.3.6.1.4.1.11.2.14.11.5.1.9.6.1.0",10,5), "False")

Probe
Name: Procurve_Cpu_Test
Type: Function
Availavble: Procurve_Cpu_Test() <> "False"
Error: if(Procurve_Cpu_Test()<>"False", if(Procurve_Cpu_Test()<80), "", concatenate("Cpu load is = ", Procurve_Cpu_Test(), "%"))
Value: Procurve_Cpu_Test()
Unit: %

Thank you!

Add 1 in the function since the CPU can return 0% utilization. subtract 1 in the value and error lines...

Name: Procurve_Cpu_Test
Code: if(oid("1.3.6.1.4.1.11.2.14.11.5.1.9.6.1.0",10,5), oid("1.3.6.1.4.1.11.2.14.11.5.1.9.6.1.0",10,5)+1, "False")


in your error line
if(Cisco_CPU_a()<>"False",if(Cisco_CPU_a() -1<80, "", concatenate("Warning: high CPU = ", Cisco_CPU_a(), "%")), "Cisco Device down")

lebowski,

Thank you for help!
I have configured a function and probe per you recommendation. Now it look like this: But I see multiple outages: And my chart look like this:

eriitguy, the only idea I have is your probe interval is conflicting with the probe. On the appearance of the device place your function for CPU [Procurve_Cpu_Test()] and see what the label does. Check your label refresh interval and modify it to be the same as your probe interval and see if they act the same. I have my probe interval set for 1 minutes and probe timeout to 25 seconds and the down count to 3.

Is it possible to graph all the time and still have a notification on failure if a probe fails? For example, I'm graphing DC voltage from MT's and I want an alert if that Voltage drops down to a certain point. I used to do this with 2 probes, but if would be nice if I could just have one probe. The problem I'm running into is when voltage gets below 24V I get the alert like I should, but I stop graphing.

Here's my current function:

Available: oid("iso.org.dod.internet.private.enterprises.mikrotik.mikrotikExperimentalModule.mtXRouterOs.mtxrHealth.mtxrHlVoltage.0")

Error: if(oid("iso.org.dod.internet.private.enterprises.mikrotik.mikrotikExperimentalModule.mtXRouterOs.mtxrHealth.mtxrHlVoltage.0")>24,"","failed")

Value: oid("iso.org.dod.internet.private.enterprises.mikrotik.mikrotikExperimentalModule.mtXRouterOs.mtxrHealth.mtxrHlVoltage.0")

Hello,

I got 600 routers in Dude with (10 probes). Now I define email notification and Im wondering how to configure it for all devices?

Ex.
My 600 devices in Services tab got probe "Internet" without notification. I want to change "Internet" probe to notification "email" in my all devices?
There is any way to change that with command line?

Best,
Pawel

sorry for my english


EDIT:
I find solution.

In DUDE->Services->select multiple ones->open context menu->Settings

Hey All,

Just having a bit of a test with creating probes. In particular we have been working with SNMP to see if a windows service is running. It works fine

My problem is that when the service fails, the monitor only turns "Orange" rather than RED.

Is there any way to change this?

With thanks

Is it possible to graph all the time and still have a notification on failure if a probe fails?

Only if you make 2 probes, one to graph and one to notify, on the one to graph just put "" in the error line and don't put anything in the graph on the 2nd probe....

Hi guys.
I monitor with dude WIndows servers. On Icon in Network map I've following info:
I would like to display information from function services_info() in notification email, which is sent, when some probe is down.
Here is my message body tekst... I don't know what is correct sintaks to display value of function in email message.

.. I don't know what is correct sintaks to display value of function in email message.

syntax <> sintaks

On what platform is the dude server installed (rb, windows OS, something else)? What version do you have there? What do you receive in the notification? Why there's no description of the obvious? As I can see you're network professional, then pretty please act as one.

For correct syntaks in notifications imho versions are not important...
But anyway, here they are:
Dude is on CHR ver 6.41 and server is Windows Server 2012...
In notification I receive no output of function services_info(), just plain text [Device.services_info()]

Hi that's my problem too. I don't know how to display function/probe values in email/sms body...
Please help.

Hello, another new to Dude user struggling with alerting on utilization. I found the post below from 2009, is there something more recent?


"Mon Aug 03, 2009 4:02 pm

To get the bandwidth displayed in the links between devices the Dude uses the delta of sent/received octets multiplied by 8 averaging over each second of collected data.
Nice to know and I have often wanted to alert on high and or zero utilization but it is not obvious how to do it, like you are finding out.

I looked into data sources but they look like this "serial0/0 (2) @ router1 tx" and I don't know how you would use one in a function or a probe...
Maybe you can figure out how to use a data source in a probe?

All data sources can be seen by selecting chart, make a chart if you don't have one, click on + to add a new chart line then click on the edit all data sources (the "..." button). In there you can see a list of "interface @ devicename tx or rx" which is where I assume that you discovered how exactly the builtin source works."

Another new Dude user ... nice thread this .... worried after reading it that MT arent that interested in Dude though :S

when will the new versions?
There is no improvement for a long time

Hi guys. I try to make disk usage probe for large disk 9Tb but snmp give negative value of disk size.
Can i do something with this?

Hi, I've been using the dude for a while now and was trying to get the bandwidth probe and alerts to work, but haven't been able to find any documentation as to how to start. Was this project/work ever followed up? All I can find are post from 2010 and back. Any help will be greatly appreciated.

I've been using the Dude for about a month now and am very impressed, the Probe Thread has been very useful. One probe I am having trouble creating is for current bandwidth utilization, giving a notification at a ceratin percentage. Here's what I've done so far:

Using the idea that (InOctets + OutOctets)*8*100/ifSpeed gives the percentage of utilization I created the function:

Function
Name: Bandwidth
Code: (oid("1.3.6.1.2.1.2.2.1.16.21")+oid("1.3.6.1.2.1.2.2.1.10.21")*8*100/oid("1.3.6.1.2.1.2.2.1.5.21")

From there I applied this function to a probe

Probe
Available: Bandwidth()
Error: if(Bandwidth()<50, "", concatenate("Bandwidth Utilization is at ", array(Bandwidth()),"%")
Value: Bandwidth()
Unit:
Rate: none

The does work in the fact that it does return a percentage, and when that percentage is passed I receive an email stating that percentage has passed and it gives me what the current percentage is.

The two problems are that this percentage does not match up with the link status given by The Dude in the network map, nor does it line up with the percentage shown on the port in the switch's web based console. Second, because these OIDs are counters if I watch this in real time in The Dude, I can see the percentage start low and then get higher and higher for 90 seconds until the next poll interval when it drops and starts again. Is there a way for it to give an average of the poll interval to show more accurate data?

I wanted to get an info message when there is a ping more than 250ms on isp to know and change to another ISP mannualy.
Why this dont work? I didnt get any notification....

Hello,
i would monitor client connected to wifi so i setup dude with this rules

dude - functions
new
name: client_wifi_function
code: ros_command("/interface wireless registration-table print count-only")

dude - probes
new

name: client_wifi_probe
type: function
agent: default

available: client_wifi_function()
error: if(client_wifi_function(), "", "down")
value: client_wifi_function()
unit: Client

work correctly, but when mikrotik have nobody connected to wifi (tipically when office is close) probe result down.
can i setup probe without error?
in other words probes never mark as down...

i tried various error ,like
error: if(client_wifi_function(), "", "")
or
error: if(client_wifi_function()>999, "", "down")
but i have always error or probe not work...

thank you in advance...

just for info...

simply i edit in this
available: 1=1

error: if (1>0,"","")

so i have never error :)

thank you again

sorry, i'm here again to ask help....

i try to monitor an asustor NAS with the dude.
i can upload mib on the dude correctly and now get value with snmpwalk .

my goal is monitor CPU and disk status (health)

i create a function with code
oid("iso.org.dod.internet.private.enterprises.asustor.asustorDisk.diskTable.diskEntry.diskTemperature.1")
then i probe this temp and alert me if is too hot.

now i try to do same thing with health
on snmpwalk i find oid and see value as Healthy
create function with code
oid("iso.org.dod.internet.private.enterprises.asustor.asustorDisk.diskTable.diskEntry.diskStatus.1")
but return 0 on data chart
i want as last value Healthy and compare it with a probe.

Thank you in advance

snmpwalk translate raw value to corresponding string,
but if you call the oid, you just have 0 or not 0 as value...
healty from MIB = 0
non-healty = not 0

thank you for reply.
ok i try as you described...

but if I wanted to value can i use ?
oid_raw("..................")

thank you in advance

ok, i understand
if i create a probe as in the attachement.

probe is ok when is Healthy, but return error when is "not equal" Healthy.
correct?

thank you

ok, i understand

probe is ok when is Healthy, but return error when is "not equal" Healthy.
correct?

thank you

Probably.. yes... but I do not have any device to test directly simulating not-healt status...

The string (non raw) values can be Healthy / Normal / Risky / Dangerous / Bad

ehm.. sorry for my english...

Healty = like new disk
Normal = like used, but with full functionality
Risky = Something on S.M.A.R.T. pre advise problems like end of expected lifetime
Dangerous = near broken disk (from S.M.A.R.T. or too many bad sectors)
Bad = the disk is gone

iso.org.dod.internet.private.enterprises.asustor.asustorDisk.diskTable.diskEntry.diskStatus.1 = disk 1 (1.1.3.6.1.4.1.44738.4.1.1.5.1)
iso.org.dod.internet.private.enterprises.asustor.asustorDisk.diskTable.diskEntry.diskStatus.2 = disk 2 (1.1.3.6.1.4.1.44738.4.1.1.5.2)

some other values can be see for volumes (iso.org.dod.internet.private.enterprises.asustor.asustorVolume.volumeTable.volumeEntry.volumeStatus.x):
Healthy
Clean
Active
Resyncing
Recovering
Reshaping
Appending
Migrating
fsExpanding
fsIniting
Degraded
Failed
Inactive

the respective volume name can be read with iso.org.dod.internet.private.enterprises.asustor.asustorVolume.volumeTable.volumeEntry.volumeName.x

with
iso.org.dod.internet.private.enterprises.asustor.1.sysAsustorID.0
you can check is is available new version of internal ADM
Possible string values: Available / Unavailable

and you can put on device appearance / label the function:
[Device.Name]
[device_performance()][rex_adm_available()]
[Device.ServicesDown]
(your must differ for mine because I replace original)

function name: rex_adm_available()
function:
if ( oid("iso.org.dod.internet.private.enterprises.asustor.1.sysAsustorID.0") = "Available"
, "Aggiornamento ADM disponibile"
, ""
)

thank you!!!!

i try and for now i use this way (monitor volume instead disk)

on VolumeStatus – 4 = Healthy (snmpwalk) right click
create probe
name asustor_volume_status_healthy
type SNMP
agent default
snmp profile v2-public
oid iso.org.dod.internet.private.enterprises.asustor.asustorVolume.volumeTable.volumeEntry.volumeStatus.1
oid type octet string
compare method ==(equal)
string value healthy

now i check also firmware and disk
thank you again

Don't ask for random things that have nothing to do with it.

Chose another forum.

After a little research, I have found a method for polling the Amazon Alexa (Echo, Echo Dot) devices on a network. There are a few ports open, but the listed ports I could find did little good. The open port I did find, that seems to work, is as follows;

#Amazon Echo Probe
Name = Amazon Echo
Type = TCP
Agent = default
Port = 55442
Send = \n
Receive = ^.

I hope this saves someone a little time.

Hello everyone,
I'm trying to monitor my network Connectivity using RouterOS netwatch & Dude.
Here's my routeros setup:
This properly reflect my IPv4 Connectivity.
On Dude side, I setup a custom function as follow:
Expected output is either "up" or "down" depending on /tool/netwatch status.

Then, I set up a probe:
Finally, I also used Labels to visually check what's going on:
Actual output is:
So far, so good. Let's test un unreachable IP address:
Expected output
Actual output:
And my probe keeps being up.

Apparently, the `if` function doesn't work the way I'm expecting it.
What am I missing ?

Dear The Dude Forum

Is it possible to monitor a https webserver?

this is for the http version
HEAD / HTTP/1.0\r\n\r\n

^HTTP/1\\.

can it be changed to https?

The probe on UDP port 123 (NTP) above does not seem to work anymore?

I've been attempting to make a function / probe for an APC UPS. Got stuck for a little bit figuring out the syntax. But I think I've got it. Two functions, and a probe listed below.

this is the function:
