Is the load always this high? How many cpus are allocated to this server? You can run

Code: Select all

grep processor /proc/cpuinfo  | wc -l

to get the number.

You can set the load_threshold threshold variable in /root/etc/pnp/npcd.cfg which is 10 by default to work around this.

I increased the load threshold to 16 but I still see the issue ?

Code: Select all

[[email protected] ~]#     grep processor /proc/cpuinfo  | wc -l 
16

[[email protected] ~]# cat /usr/local/nagios/etc/pnp/npcd.cfg | grep load
# use_load_threshold - enables/disables load watching
# use_load_threshold = <0 / 1> (default: 0)
#use_load_threshold = 0
# load_threshold - npcd won't start new threads
# if your system load is over this threshold
# load_threshold = <float value> (default: 10.0)
load_threshold = 16.0

The correct file location should actually be /usr/local/nagios/etc/pnp/npcd.cfg as you have, and you need to run service npcd restart after for it to take effect.

I agree though, a load of 16 is somewhat high. How many hosts/services total are you checking? Is there any other application running on this server?

I have attached the screen shot for you reference. I have commented out the cpu_threshold to see what happens.
