Yeah, that'd cause it.

You can see what sort of max-rep value this device can handle and then enable that in its settings.

Cisco stuff usually handles 1000 pretty well (defualt is 20!), But ofc nxos is trash.

Sorry, it's the Cisco Nexus 6000 Switch.

Maybe it could be due to the distance to the device ? (the round trip  from server to device is - 275ms.)

It means your device is slow and taking too long to return the requested data.

You've not actually really included any useful information though. What is the device?

Hello,

Some devices takes very long to complete /opt/observium/poller.php process.

For example i took one of them and run:

/opt/observium/poller-wrapper.py --host hk2net01a -d

/opt/observium/poller-wrapper.py:568: Warning: Data truncated for column 'process_name' at row 1

The debug txt shows that it freezes for about 4mins on this line:

and almost after 5mins it resumes. What could be the reason ? 

Thanks.
