ncpa hangs if mounted nfs partition has a problems #757

Are there some informations regarding this issue in the |
Is there really a newline after the equal sign?:

I cant reproduce this issue with a "stale file handle error" on a mounted nfs share:
|
There is no something interesting in the log. Log writing just stops.
This works for me: Be careful, if you use nfs server for remote connection to centos7_ncpa_test, you will lost remote connection channel. Blocking rule can be removed with: |
Thanks for providing this info. |
Thanks for providing this info, now i can reproduce this issue. :) |
Did you test with these parameters?
I have checked again for NCPA 2.2.2 configured as above and I can't see the problem. Moreover, strace doesn't contain any stat or statfs calls to NFS mounts. |
Yes, you are right. Using your configuration solves the issue for |
Good news, i have found and fixed the issue, but i dont understand why this works with |
…rprises#757) and follow_symlinks doesnt work because type conversion bool(config.get(...)) of a string returns True.
The configuration directive This seems to be an issue with psutil:
In both cases i have to hardkill the python process, because they never came back. |
I have opened an issue in the psutil project. Maybe they can help us with this issue. |
Fixed some configuration directives doesnt work, e.g. all_partitions and follow_symlinks (#757)
Hello, I have been having this issue periodically. Is there any ETA on this issue. We currently use Nagios XI 5.8.6 with ncpa-listener (ncpa 3.0.8) for monitoring. If there is an issue with an NFS mountpoint, a lot of service checks end up with "UNKNOWN: Execution exceeded timeout threshold of 60s". Thank you, |
I dont know the release date of 2.4.0, but i found this: |
The problem detected in 2.3.0 and 2.3.1 versions. Tested on RHEL 7.6.
