Higher CPU utilization after upgrade to 5.5.1

[Kujab]

Hello,
I can see higher CPU utilization after upgrade to 5.5.1 on 19th of July.
Previous values were about 0,7. After upgrade it's constantly above 1.
Is that correct? Or anything wrong?
Best regards
Jakub

Can you post the output of the following

Code: Select all

ps -ef|grep nagios.cfg

[Kujab]

This is output:
[root@localhost ~]# ps -ef|grep nagios.cfg
root 17773 13519 0 09:12 pts/0 00:00:00 grep nagios.cfg

You have 2 nagios parent processes.

Run the following

Code: Select all

service nagios stop
killall -9 nagios
service nagios start

After killing processes it looks like this:

Code: Select all

[root@localhost ~]# ps -ef|grep nagios.cfg
nagios    8551     1  3 14:29 ?        00:00:00 /usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg
nagios    8655  8551  0 14:29 ?        00:00:00 /usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg
root     10515 13519  0 14:29 pts/0    00:00:00 grep nagios.cfg
[root@localhost ~]#

Load average is still higher. I will monitore that for one day.

That looks better it should start to drop, will take a bit of time..

Let us know how it turns out

[Kujab]

Looks better:

20180725 - localhost-current_load.png

Also processes are still the same:
[root@localhost ~]# ps -ef|grep nagios.cfg
nagios 8551 1 1 Jul24 ? 00:12:53 /usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg
nagios 8655 8551 0 Jul24 ? 00:00:03 /usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg
root 13041 10146 0 09:01 pts/0 00:00:00 grep nagios.cfg
[root@localhost ~]#

I suppose we can close this ticket.

Should be fixed in upgrade procedure, it never happened before.
