Excessive amount of nri-perfmon processes running #25

Closed hpapazov closed 3 years ago

hpapazov commented 3 years ago

Hi, Is it normal to have 20+ nri-perfmon processes running on a given host? Recently we experienced memory issues with couple of our clients' web server hosts. While investigating, our support team discovers 20+ nri-perfmon running there. They told us that it looked like the processes were hung and continually spawned off a new process.

nri-perfmon version: 0.5.1/nri-perfmon-release-x64.zip

Thanks!

That's a new one! Can you send over a couple things:

  1. The config file for counters you're using (default file is config.json)
  2. Look in Windows Event Viewer for any events from nri-perfmon (that should be the "source" name). If you find any, please use the "copy" button in them and paste into a text doc.

We may also want to run nri-perfmon in verbose mode at command line for a minute and send over its output. That's explained here. I'd say this is a next step though, the current config and log messages are first step.

Our support team did not find anything in the Windows Event Viewer. This is the config: { "counterlist": [ { "provider": "Counters", "category": "SMBClientShares", "counters": [ { "counter": "*" } ] } ] }

And this is the command `name: com.newrelic.perfmon description: Perfmon On-Host Integration protocol_version: 1 os: windows commands: metrics: command:

@hpapazov I don't see anything glaring, can you try the latest version of nri-perfmon to see if it happens again? I added some cleanup of old data after each cycle, which may help in case the service is quietly running out of memory.

Also can you try verbose mode on one host to see what it outputs? https://github.com/newrelic/nri-perfmon#verbose-logging-mode

Any update @hpapazov ?

Also to note, the latest release is now this one: https://github.com/newrelic/nri-perfmon/releases/tag/0.6.1 I suggest trying it and letting me know if you still see the issue.

Sorry @sschwartzman, our operations team did not have the chance to try the above. For the time being they just disabled it. I am sorry, at this point I do not have any additional information that might be helpful.
