RRD Graphs stop working

Gertjan

Any idea how to make it work again?

Yep. Simple. Start dealing out a lot of info.
Right now, I'm having a hard time trying to understand what doesn't work well on your system.

@nikkon:

I see a strange behaviour on the RRD Graphs section.The quality tab stoped recording/drawing data for 2 days.

Images are being generated from the 'rrd' files.
Check timestamp of the all the 'png' images, they are here: /tmp
These png images are created when you view the corresponding Status=> RRD Graphs page.
Check if RRD files are updates regularly - you can find them here : /var/db/rrd

GUI test: The quality rrd chart is being fed by a tool called 'apinger'. You can see it here : Status => Services, its called "apinger Gateway Monitoring Daemon" : is it running ?
PUI test: Enter into SSH, and execute

ps ax | grep 'apinger'

is it running ?

Check this file : /var/etc/apinger.conf
Does it look good ?

Check this file /var/run/apinger.status
Is it updated regularly ?

Last, but not least: what is your setup page "System => Gateways" ?

@nikkon:

This is quite critical cz we rely on this in order to check ISP services on some locations.

Restarting apinger doesn't do the job ?
Logs say something about apinger being stopped ?

Understand that this one is running for years on my pfsense box, and I'm pretty sure I'm not the only one.
Your question boils down to: what is so different with your setup ?

Also, when you did your update did you change from 32 bit to 64 bit or the other way around? Any changes like that?

Gertjan

Hummmm, that question would open this door : https://doc.pfsense.org/index.php/Upgrade_Guide#Changing_architecture_.2832-bit_to_64-bit_or_vice_versa.29_during_upgrade
You think nikkon would hide that kind of information ???

I presume: it was working for day, weeks, and with no-one touching the box, ping graphing stopped.

========================

/var/etc/apinger.conf look good.

cat /var/run/apinger.status

Because my ISP uses PPPoE i got only gateways like 10.0.0.1 so i have added 8.8.8.8 in the gate section as Monitored IP.

The files under /var/db/rrd seem to be accesed today:

Arpinf restart didn't changed anything.

No updates…all boxes are fresh 2.2.1 installs.
On all boxes i use Watchdog...so every process will be restarted of fails.

kejianshi

I'd do another one of those fresh installs - Wipe the drive.

Also be sure that Gateway monitoring is on.

nikkon

ok it seems to work now after 3 restarts of the arping.
strange.
thx for helping.

kejianshi

That is strange. Glad it was nothing major.

Your "8.8.8.8" is considered as the gateway.
Check Status => Interfaces: what is "Gateway IPv4" ?
Are you sure that "8.8.8.8" is always replying to a ping (this is a main Google DNS server google-public-dns-a.google.com) - I wouldn't consider "8.8.8.8" as a valid ping replier. Its a very loaded DNS server, and in case of overload it starts to ditch less-important protocols, like 'ICMP'.

When you say : "10.0.0.1" you are talking about your WAN IP gateway, right ? So you have a router-behind-router setup ?
If possible, hook up pfSense directly to the net.

nikkon

I use 8.8.8.8 as monitored IP in order to have apring working…if I use ISP gate alocated via pppoe is always down, even if i have net.
this can't be changed. it's on the ISP.
Yes 10.0.0.1 is my wan gate.

kejianshi

I would reduce my pings from every 1 second to every 5 or ten seconds in that case.

Its just as useful for you and less likely to have your packets dropped as a nuisance.

I did same and my apinger started behaving better.
