CMK version:
Checkmk raw edition 2.1.0p27

OS version:
Ubuntu 22.04

Error message:
I have a large number of pending services on the same host. These services are mainly related to the interface on juniper, although on the same host the services below using the python script I have configured in Integrate Nagios plugins still execute normally. How do I determine where the error or configuration is wrong?

Output of “cmk --debug -vvn hostname”: (If it is a problem with checks or plugins)

Hi @toanpk. You have a lot of active checks running against the Juniper device, will already create some load. Now Checkmk is very powerful in it’s monitoring, which means, that there is a considerable amount of queries performed. The “Check_MK” service tells you, that there is a timeout. You want to read and understand the following blog post.
