Service Check Timeouts

[ssax]

Yes, that is the profile I was referencing, I would still make the changes requested as it would be recommended based on the logs.

So you're still seeing timeouts after the load issues have been resolved?

Send the output of these commands as root (I added another command):

Code: Select all

ulimit -a
su -s /bin/bash -c 'ulimit -a' nagios
su -s /bin/bash -c 'ulimit -a' mysql
su -s /bin/bash -c 'ulimit -a' apache
netstat -s
ethtool -S eth0
sar -A

Please PM me another FRESH copy of your profile.zip as well so I can see the latest logs, that will give me more accurate information to go on.

Thank you!

Hello @Dusan.Mandic

Sorry about the delay, @ssax is out of the office and want to have you follow up and send the info and System Profile over so we can take a look at things.

How certain are we that would lead to a solution for those service check timeouts?

Have any users experienced any issues after attempting DB upgrade?

@pbroste

any answer to above?

Hello @Dusan.Mandic

To answer your inquiries;

How certain are we that would lead to a solution for those service check timeouts?

Definite advantages to NDO3, in that the messages are not queued up. We would suspect that the load on resources is similar or a bit less.

Have any users experienced any issues after attempting DB upgrade?

We provide instructions on how to upgrade but recommend a backup just in case something goes wonky.

Installed NDO3DB but it looks like all the timeouts are occuring at once now. ill give it a while to optimize.

Hello @Dusan.Mandic

Let's go ahead and let things run for a bit and look at this again; revisit this on this in Answer Hub when we start to see things act up again. We definitely require attention to logging so we can dial any other optimizations in. However, looking over the history, I believe that we have implemented all optimal settings and configs.

Quoting a previous response. As we advance, the environment is tipping towards the max hosts and services that one server can efficiently handle. We recommended max is 20k; that is only a recommendation because it depends heavily on the type of service checks and the number of hosts, etc.

You can only do so much on a single XI server, you'll need to do what you can to mitigate the impact, but you should start looking at adding another XI server soon if you continue to experience load/kernel message queue/performance issues after doing the mitigation.

Let me know if you have any questions or if I can clarify anything.

Thanks,
Perry
