Hello. We have a problem with gaps when there are 250+ devices. Can anybody help?
[OK] Composer Version: 1.9.0
[OK] Dependencies up-to-date.
[OK] Database connection successful
[OK] Database schema correct
Typically when we see this, it’s because the polling server cant keep up. Might try to add additional pollers or increase the server specs if a VM.
What solution did you implement to resolve your problem?
- Decrease polling interval? Reverse of https://docs.librenms.org/Support/1-Minute-Polling/
- Add additional pollers? See https://docs.librenms.org/Support/Performance/
- Add resources to your VM?
- Distributed pollers? See https://docs.librenms.org/Extensions/Distributed-Poller/
I distributed pollers for 2 groups (servers and network devices), it got better but not at all. I don’t know if I could reopen this topic.
For the first group (548 devices) it takes 350-400 +/- sec, but sometimes it can be successfully drawn in graphs.
For the second group (71 devices) it takes 200 +/- sec and most of the time it’s ok with graphs, but not all the time.
I suppose there are some polling problems because of bad discovering too.
I’m trying to disable some poller and discovery modules, but it still takes too much time:
614 devices discovered in 33551 secs
Unfortunately, the problem is not solved.
