I can log into webbox for my aps and bhs but no mrtg data is being collected. Is there a switch that needs to be set for this to collect data?
I go to interfaces, then pick the interface (eth1, wlan1 etc) and click on graph but it is blank. Shows last update as jan 1 1970.
Traffic is passing. I’m on ROS 4.6
What can I do? Thanks in advance.
Hi,
maybe you didn’t set NTP client/clock on your RB and you are still in sweet 70’s 
or ’ store-on-disk=yes’
Regards, Grzegorz.
hmm. Should I be using unicast or broadcast?
Side note: I check the scheduler and look at a script I created but isn’t running correctly it shows Jan 1970. Knowing that I think I should put in some different ntp servers.
Can someone recommend a site where I can get a known good ntp server to put into the field under ntp client. Apparently the ones I found are no good.
Hi,
My favorite is 150.254.183.15
Regards, Grzegorz.
I set the ntp to your favorite IP. I also set the clock which was also in the good ol 1970. Graphs appear to be back now.
many thanks.
Instead of using random IPs please use NTP pools, or look up a close NTP server that is open to the public. That way you can help make sure the people running these as a service keep running them and don’t shut them down due to abuse.
Here’s an interesting and related link: http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.152.2286. A router manufacturer used the University of Wisconsin’s public NTP server as a default and caused effectively a DoS attack.
correcting clock and ntp client fixed the mrtg graphs. 
On reboot the time is back to 1970. I wonder if the ntp server I picked has disappeared?
Can I put a pool in the ROS instead of an ip?
also when I reboot I lose all mrtg history. I have a 433 board with a 4gb microsd card. Is it possible to tell mrtg to save data to this card? I assume someone has done something like this. I’m not much a programmer but could follow a wiki or script if it isn’t an option in the ROS
try pool.ntp.org
I have been able to insert pool.ntp.org which is changes over to a 72.x.x.x ip. I have applied it and am waiting to see.
I set the clock as well. I hope doing that isn’t a override. I’ll post back.
So it’s been awhile. This was lower on the ‘immediacy’ list so to say.
I ended up setting up ntp on the dude server that is on the network. for some reason I was having trouble getting an off network ntp server to route correctly???
I’ve noticed that the mrtg graphs are only collecting data when the web window is open. No history is stored so if I come back to the web a few days later there is not data. It starts collecting all over.
I’ve poked around the forum over the last few months but can’t seem to pinpoint why.
Any insight?
