Graphs don't work every night

Did you also increase the "load_threshold" or you left it at 60?

here is the disk performance graph

Would it be possible to see the disk latency stacked on there please? Both the host and the guest.

Hi

I stopped the Nagios Backups last night as we discussed.

Last night was much better. I was looking at the logs and I the load remained below 100. This is on the ncpd.log. I still saw some problems with the graphs. However most of the graphs were ok without any breaks.

I am going to try to stops my tape backups. This will be done in my backup tool. I will only stop the backups for this specific server

Lastly, do you recommend to increase the threshold to 100? Right now is at 60

Is this an adequate long term solution? Ultimately this is still looking like a resource contention problem - but if you choose to repair it by way of limiting the amount of resources that's OK by us.

Like the above - this would be more of a patch than a repair, but it could very well resolve your problem.

I would look at implementing a RAM Disk AND also RRDCached:

http://assets.nagios.com/downloads/nagi ... ios_XI.pdf

These should help with load.

I did a test. I stop the nagios backups and helped a lot. I ran backups last night and I saw the problem again and the graphs stop working at the same time we started to run backups

Did you implement ram disk or rrdcached as suggested by Box293?

No

I moved the VM to high performance HD

bosecorp,

Did moving Nagios XI to a high performance disk resolve the issue for you? If so, are we good to lock this thread?
