RRD Quality Delay values wrong after updating to 2.2

deltix

I'm seeing the same thing. Fresh installation, ping is 5-6ms, apinger is showing 0.5ms. After restarting apinger it looks fine.

Thanks to wbond for letting me know about this thread. I've noticed the same thing; apinger delays are much less than a manual ping or traceroute will show; and restarting apinger corrects the problem.

wbond

It looks like in my case restarting apinger only worked for couple of hours, and now it's back to underreporting the RTT.

wbond, RRD is showing about 5ms, it's supposed to be about 25ms? Are you sure you're pinging the same IP address?

wbond

Harvy66, yes, same ip address and it usually measures in the mid 20's using ping and was consistently in that range in 2.1.5

I just pinged from pfsense and results were:

Sorry - didn't get any notifications that anyone had replied to this.

Anyway - restarting apinger has put the stats back to normal. I'll keep an eye on it and see how long it looks sensible ;-)

wbond

Restarting apinger only seemed to fix it for a couple of hours for me. I ended up changing the probe interval on the gateway to 2 seconds and changed the Down value to 20 and the RTT has been running at normal levels for 2 days now. No idea why this would make any difference, but it seems to.

Just to let you I tried a workaround to restart apinger when monitoring alarm goes off and it seems to do the trick for 2 days now:

@cmb:

Could you enable gateway monitoring debug logging under System>Advanced, Misc, check "Enable gateway monitoring debug logging", and post your apinger logs?

I think I may have a clue here…

I restarted apinger and cleared the logs.The RRD RTT values where then ok for some time, but the reported values "went silly" when the log showed:

Feb 15 22:01:35 apinger: alarm canceled: GW_WAN(###) *** delay ***
Feb 15 22:01:22 apinger: ALARM: GW_WAN(###) *** delay ***
Feb 15 19:27:16 apinger: alarm canceled: GW_WAN(###) *** delay ***

The graphs changed at the same time as the first "alarm canceled" event, so it looks like its related to the alarm clearing rather than triggering.

I have the same problem, a VSAT wan (supposed to be always more than 500ms) and a WIMAX (supposed to be always more than 120ms), after 2.2 upgrade (well, fresh installation) are 20/10/0ms
