These are the commands that are failing to that Windows server.
Code: Select all
Failed to execute command: PSCheckSystemEventLog
Failed to execute command: check_tasksched
The following error was generated by a check from the Nagios server but the command is not defined in the nsclient.ini file causing the unknown command message.
Code: Select all
Unknown command(s): pscheckapplicationeventlog
It looks like the problem is with how the commands are defined in the nsclient.ini file on that server so make sure they are correct and that the powershell scripts on that server exist and that they can be run on the server.

Those errors came from the nsclient.log file from your post from Wed Mar 22, 2017 7:36 pm.
What system did that file come from?

this is happening again and again
Does anyone on this forum have an answer
Why is it when I post a serious problem nothing gets answered
All the vms just posted a false error on all nrpe checks
How about a solution?
This is a Nagios issue.
I hate Linux cant you run Nagios on a windows system
all my problems are with Linux machines my other posting is about Linux issues also again no answers on that one either.

I don't see the nsclient.ini or the answer to
tgriep's question:
What system did that file come from?
Did you provide them to someone else?

They are coming from every bloody VM on the network not just one
Every dam nrpe check times out with 120 secs
Do I need to upgrade nrpe?
Is Nagios just not the right tool for this?
What is up with Nagios
Does it need to be a physical machine or can it be a VM ? I asked this before no answer
is version 4.1 core no good?
cant be the config has to be the core product
Does the Ubuntu machine need more resources if so what is the requirements

I believe all these false positive errors are caused by the load on the Nagios server
The only thing running in this server is Nagios
When I run Top it shows different number from what the cpu load shows on the server from Nagios
on Nagios CRITICAL - load average: 0.76, 6.25, 5.08
TOP
top - 23:33:22 up 13 days, 5:43, 2 users, load average: 0.27, 2.62, 3.82
Tasks: 207 total, 1 running, 206 sleeping, 0 stopped, 0 zombie
%Cpu(s): 0.2 us, 0.3 sy, 0.0 ni, 99.5 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st
KiB Mem : 8072636 total, 946920 free, 5619396 used, 1506320 buff/cache
KiB Swap: 8286204 total, 8286204 free, 0 used. 2056836 avail Mem
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
very different
the Nagios server is a little sluggish at this time but I am using ssh to connect to it.
Thoughts

It could be the load of the server causing the issue as well as the version of Nagios Core.
Try and upgrade Core to the latest version which you can find in this link below.
https://www.nagios.org/downloads/nagios ... 1490878378
Without seeing the errors, log files and how the system is configured, it is difficult to help out.
If you have the issue again, the first thing you can do is to post the nagios.log file which, on a default install, can be found in this folder.
That is the current days log so to post a log file from a previous day, you would find them in this folder.

Nagios is the right tool. Personally, I think you need to learn how to administer the environments you're working with, AND THEN learn how to use Nagios. I feel like you're throwing all sorts of noodles at a wall and seeing what sticks. This leads to countless rabbit holes, and plenty of wasted time all around.
Many of these books may help you -
