Hi Scott; The first thing I would check would be to see if any new devices have been added to your SmokePing config around the time you started having problems. If so, check the SmokePing logs for warnings that look like "Warning: Polling took longer than the interval step." or something similar. What could be happening is that at some point, you had X devices monitored, and they took, for example, 298 seconds to scan. If you added another device, all of a sudden it might take 302 seconds to scan. If you had your scan cycles set to 5 minutes (300 seconds), this means that SmokePing can't complete a round of scanning before another one starts. This could definitely cause the problems you've been seeing. If this is the case, the solution is to either lenghten the scan cycle, remove some hosts, increase concurrency (although I don't think that's supported in 1.x?), or upgrade to the current SmokePing series and implement multiple monitors and/or master/slave. Cheers, Peter Scott Moseman wrote: We're running Smokeping 1.34. Yes, I'm aware its old, but it's been deployed forever and it's been working fine. Lately we've been having some weird issues with missed polls. I have attached a sample showing the last 3 hours and it includes 3 missed holes. This happens across every device in the Smokeping config. We have a script that runs every 5 minutes to update the config if there's new entries and part of that process is to verify the process is running (and restart, or start, if necessary). It logs what's going on. When the config updates and Smokeping restarts, there's never a gap. According to my scripts, and looking at the age of the Smokeping process that's running, these gaps were NOT caused by Smokeping having failed execution. Also, I setup a ping tool to monitor the switch, router and an external address every SECOND for awhile. There was never a lack of connectivity during these gaps in Smokeping. Is there any means to troubleshoot? I will enable the syslog function to see if it provides any details about what's going on.Thanks, Scott |
