After we upgrade our NetApp from ONTAP 9.8P16 to 9.9.1P16 the Time spent waiting for special agent drastically increased:

Does anyone else have seeing this behavior?

Any feedback is very welcome.

I have some Netapp with version 9.9.1p16 in my monitoring and there are no very high agent times, normal times here are between 5 and 10 seconds.
Before i had some Netapp devices with many many Qtrees defined. These devices had a very high agent response time. Here i had to remove the QTree section from the agent.

I dont see qtrees on this filers.
There are huge delays in communication right from the beginning:

We opened a ticket for that. Lets see but first answer was: We dont care about checkmk :slight_smile:

Lets see.

The qtrees was only the reason on one problem system.
What i had done for the troubleshooting is executing the agent with “–debug” to see where the longest wait time is.

I added some debug code to print out the timing of the query. I didnt checked all queries but most of the lasts ~5 sec:

As we run 61 queries it ends at 300 sec. Lets see with what Netapp engineer will com back to us.
