RRD graphing

nocer · Aug 8, 2008, 10:05 PM

just fyi, here's excerpt from syslog…after very fresh install and first bootup. No other RRD related logs. It looks like there some necessary files are exist and seem to be updated by the update script, but doesn't show any images. It might be a timing issue for "No such file or directory" errors because the file is exist in the same directory now.

any chances the "quality" tab to be fixed soon? if I were to fix it, I would incorporate the way done in 1.2.x but 1.3 rather introduces apinger so I'm being a patient for any newer build has it fixed. By the way, previous problem has recovered by install fresh of way old iso image which known to show RRD correctly(but not quality) then upgraded to the current.

nocer · Aug 13, 2008, 2:49 PM

Still no luck for rrd quality but Traffic Graph at this time. SVG shows nothing at least since pfSense-Full-Update-1.3-ALPHA-ALPHA-20080811-1639 build. It worked just fine till pfSense-Full-Update-1.3-ALPHA-ALPHA-20080809-1642. Assume something must have been messed up between those builds. Try fresh with pfSense-20080812-2048.iso, which seems to be the latest iso for now.

nocer · Aug 14, 2008, 1:46 AM

Tried even newer build/iso, SVG still broken. Is this my setup? Anybody noticed? Or doesn't care because it's only a cosmetic and there are tons of othres with high priority? I'm just hoping somebody from team respond.

Will try install 1.2.1-RC1 fresh then upgrade to 1.3-A-A to see if there's any chances that SVG back in normal.

databeestje · Aug 16, 2008, 9:01 PM

Not sure here, but both the SVG traffic graph and the RRD quality graphs appear to be working normally.

Only issue being the empty items in the drop down. They work though, the labels are just empty.

jjstecchino · Aug 16, 2008, 9:39 PM

RRD graphs do not work for me. the page has graphs headers but no graphs.
SVG traffic works well however interface traffic graph on the dashboard has a problem. The LAN graph is ok but the WAN shows incorrect info on my setup

jjstecchino · Aug 16, 2008, 9:43 PM

OOPS found the problem. RRD graph backend disabled by default on a new install. Going to RRD graph ->setting->enable RRD backend, now I have rrd graphs.
Any reason for having RRD graph backend disabled by default on a new fresh install?

databeestje · Aug 16, 2008, 9:54 PM

No particular reason. The tag is not part of our default config.xml

nocer · Aug 17, 2008, 11:34 PM

Thanks databeestje,
hmmmm…still no luck with the latest upgrade, yes RRD backend is running.
could you let me know which build do you use? Let me do fresh once again with your specific build.

BTW the SVG problem was seen on the dashboard, not the traffic graph tab. because dashboard tries to
pull the value from pseudo "pppoe0" but traffic graph tab pulls "em0", which is real wan i/f in my case.
ie)
dashboard: http://192.168.33.1/graph.php?ifnum=pppoe0&ifname=wan&timeint=3
traffic tab: http://192.168.33.1/graph.php?ifnum=em0&ifname=wan&timeint=3
(192.168.33.1 is my setup for the LAN side of course)

It's a good thing you said it's a pppoe connection. Now I know where to look. The em0 interface is the pppoe parent interface?

yup, em0 for WAN and em1 for LAN.

how about RRD Quality tab? Mine is still doesn't seem to work, it's all RED. It's been RED since the very begining of 1.3-AA and I believe someone has also posted the same sometimes ago.

If you can't ping the default gateway of the interface, the graph will be red. There was previously a manual add to the config to change the monitor IP to something else, but I remember there being an option in the 1.3 gui to change this. I'm just too lazy to boot up a 1.3 test box and find where it is.

I of course ping the default gateway, but in fact, because I am getting IP address via PPPoE so the addresses will change every(not exactly) boot then I just can't configure those gateway/monitor IP in the System:Gateways. Description for the monitor IP says "Enter a alternative address here to be used to monitor the link. This is used for the quality RRD graphs as well as the load balancer entries. Use this if the gateway does not respond to icmp requests." so I put some real address one of my co-lo box but RRD still red. This used to work without any extra config since 1.2, I will try 1.2.1 and see how it is done in 1.2.1.

Thanks for your info anyway.

databeestje · Sep 21, 2008, 8:05 PM

If all is wel this should now be fixed for dynamic interfaces!

Please test!

nocer · Sep 22, 2008, 2:45 AM

Hello,

@databeestje:

If all is wel this should now be fixed for dynamic interfaces!

Please test!

Thanks for follow up, however, I no have time playing with 1.2.1 since then so go with 1.3-AA and I'm actually stuck to configure the addresses which "dynamically assigned" by my ISP. Configuring System>Routing>Gateways requires addresses to be static. It can't be done if there's some sort of auto-discovery method, or even alias, or whatever the way $WAN can be used for gateway.

I of course statically configured addresses just for now and tested then I saw the config for the "apinger" successfully created in /var/etc and rrd graph is also created in /var/db/rrd/apinger-<monitor_ip_addr>.rrd and is updated correctly, but in fact, when I click Quality tab in RRD with my hope to see the apinger graph, nope, it just returns me wan-quality.rrd graph which I continuously seeing the ALL RED graph.

It could be my config for the Gateway wrong, I only set "WAN" for the interface, "TEST" for the name, address of my WAN interface for gateway, don't check default gateway, and one of my co-lo address for monitor_ip. That's all.

Could someone tell me correct way to configure this Gateway tab please?

cheers,

EDIT : I meant to say that how I can specify the "Gateway address" which
obtained by PPPoE and will be changed every boot.

EDIT2: It looks fine in the Status:Gateways I see green and updated every
10 seconds or so, but somehow continuously getting "php: : Could not find
gateway for interface(wan)." in syslog.

EDIT3: And…now the Quality RRD graph is all WHITE...means empty? or nothing?
Much better than all red but I just dunno :P</monitor_ip_addr>

Hi,

Been playing with the 20080923-0645, and can't stop "php: : Could not find gateway for interface(wan)." messages in the syslog. It seems to be harmless but annoying and hogs syslog…I've deleted Gateway and apinger related but still getting these. Nothing happens either for Quality RRD Graph, it doesn't matter if Gateway/apinger configured or not, no graph, complete white(or blank). Grab some new build in the weekend and see if there's any progress...

cheers,

databeestje · Oct 31, 2008, 9:05 PM

I finally added backend support in the gateway groups for the dynamic interfaces.

Possibly failover even works.

Not sure about the RRD graphs, it might even work.

nocer · Nov 1, 2008, 12:08 AM

Thanks databeestje, let me grab new 2.0 snaps.

BTW: I'm still having annoying "php: : Could not find gateway for interface(wan)." messages in the syslog. Could someone tell me how I can stop it. Gateway is of course configured properly, and always green by apinger.

cheers,

databeestje · Nov 2, 2008, 1:24 AM

That's fixed too.

nocer · Nov 10, 2008, 2:58 AM

Hi,

Finally catch the latest snap and my box has been up-to-date. I also noticed that the kernel has already moved to 7.1, WOW!

YES - all the RRD thingy works fine now including "Quality" tab, and annoying PHP messages are gone. Thank you :D

BTW, I happened to have found that apinger now picks my WAN address correctly but also picks a non existing address, 127.0.0.2, too then the following is logged to syslog;

Nov 10 11:29:22 apinger: ALARM: wan(127.0.0.2) *** down ***

Of course, apinger creates its config while booting so that deleting 127.0.0.2 from the config doesn't help(unless you never reboot). Hope this would be cleared in the next snap.

cheers,
