Dear Team,
We are monitoring 630 hosts with 6500 services.
Server Config mentioned below:
RAM - 24GB
CPU Core - 12
HDD Size - 550GB
Whenever I do any config modifications in existing host, "Apply Configuration" is taking 3-4 hours to complete.

Please help us to overcome this issue

Do you have a lot of failing checks on your system? The reason I ask, is in the past I've seen failing SNMP checks increase the load substantially.
A few other questions -
- What sort of disks is the XI machine running on?
- Does it always take hours to finish?
- When you apply configuration, please run a tail -f /usr/local/nagiosxi/var/cmdsubsys.log - prior to doing so, then post this for us to review. This should show us what's taking so long for the system to finally successfully apply.

There appear to be quite a bit of failing checks - is this normal in your environment?
What is the full output of these commands?
Then, the full output of these two as well -
Code: Select all
ps -eo pcpu,args --sort=-%cpu
ps axo rss,comm,pid \
| awk '{ proc_list[$2]++; proc_list[$2 "," 1] += $1; } \
END { for (proc in proc_list) { printf("%d\t%s\n", \
proc_list[proc "," 1],proc); }}' | sort -n | tail -n 10 | sort -rn \
| awk '{$1/=1024;printf "%.0fMB\t",$1}{print $2}'

Just checking in since we have not heard from you in a while. Did
@rkennedy's post clear things up or has the issue otherwise been resolved?
