Nagios XI reporting features not working

[MNcomputer]

Hello,

We have Nagios XI, and our reporting feature has stopped working\displaying ping, cpu usage, memory usage, etc. Wondering how to reestablish the connection to active these reports again on each host\server?

Thank you!

how large are teh reports you're attempting to generate? does it work if you reduce the size of it?

reporting generally depends on SQL, which shouldn't be disconnected from the machine at all.

Can you run the following and report the output?

Code: Select all

tail -100 /var/log/mysqld.log

Additionally, can you describe which pages you are trying to access?

Hi, I worded that wrong, sorry about that. It's the performance graphs that aren't working. Showing the CPU usage, memory, etc.

doh.

this article should solve it for you - https://support.nagios.com/kb/article.php?id=9 - generally an issue with RRD processing.

The article @tacolover101 mentioned can help.

Also make sure crond is running

Code: Select all

service crond status

and that the nagios user isn't expired

Code: Select all

chage -l nagios

Have you made changes recently to your XI server?

Hi,

I read the article, and did command:

watch 'ls /usr/local/nagios/var/spool/perfdata/ | wc -l' from: https://support.nagios.com/kb/article.php?id=9

and it is running, but showing a " s: cannot access wc: No such file or directory" on the screen now. Wondering should I wait for this to complete, and see if the graphs start working again?

Thank you.

[scottwilkerson]

it is pretty odd your system doesn't have the wc binary, but you can install it with the following command

Code: Select all

yum install coreutils -y

I will add to this post and say if somehow the coreutils package was uninstalled, it could be causing all the issues you are having.

[MNcomputer]

Thank you, that worked.

Do I run the this command now, or do I wait the 30 minutes to see if the graphs start working?

Run this now?
find /usr/local/nagios/var/spool/perfdata/ -type f -delete

[scottwilkerson]

I would wait just a bit to see if the graphs start populating, although I would run these to see if the numbers returned are extremely high (like over 20,000)

Code: Select all

ls /usr/local/nagios/var/spool/perfdata/ | wc -l
ls /usr/local/nagios/var/spool/xidpe/ | wc -l

I would also consult with anyone who has access to this server to see if any other packages were removed, they could severely impact the running of Nagios XI
