The logs are oddly quiet.

When you say you increased the memory, I assume that is the total system memory and not the mem allocated just for logstash(per the KB provided), correct? For the logstash memory I would allocate 1024M.

What is the output of "chage -l nagios" ?

Do you see any errors or warnings in /var/log/cron ?

Please gather a profile the next time you see a dip as well as a screenshot highlighting the dip and the time it occurred. I'd like to see if can see anything interesting being logged when there is a dip. Please also verify the time on the NLS machine with the "date" command as well as the time and timezone on the machine running the browser used to access the NLS web UI(it adjusts according to the browser's time).

That said, I would also suggest increasing the memory that logstash is allocated per https://support.nagios.com/kb/article/n ... g-576.html - I don't see logstash crashing, but this may help it's behavior.

It is possible that it might have just been a Memory issue. I have increased the memory from 8GB to 65GB and the logs haven't dipped like that in for a few days now. Checking the current memory usage on the server, it does show that it is constantly using a good average of 35GB of Memory. So that definitely might have been the issue all along!

Thanks for the update!
