Hello @Mahesh786

Thanks for sending over the System Profile.

We see 'NCPA' service checks with the following error and timing out.

Code: Select all

error: [Errno xxx ] Address family not supported by protocol

That system may have IPv6 disabled, Let's edit your ncpa.cfg on the remote system (not the XI server) and set this under the [listener] section:

Code: Select all

ip = 0.0.0.0

Then restart the listener on the remote server (not the XI server):

Code: Select all

systemctl restart ncpa_listener

Code: Select all

sudo ss -tulpn | grep -Ei 'LISTEN|ESTABLISHED'

Results:

tcp LISTEN 0 128 0.0.0.0:5693 0.0.0.0:* users:(("ncpa_listener",pid=1588,fd=11))

Code: Select all

systemctl status ncpa_listener

Then test again and see if it resolved it.

If it's still not working, attach your ncpa.cfg from the remote system and send this information:

What OS/version is the remote system running?

Code: Select all

uname -a
cat /etc/*release
/usr/local/nagios/libexec/check_ncpa.py -V

To help tackle the timeout issues:

Want to increase the check timeouts: for 'check_ncpa' by adding -t XX number of seconds timeout.

-T TIMEOUT, --timeout=TIMEOUT
Enforced timeout, will terminate plugins after this
amount of seconds. [60]

Code: Select all

vi /usr/local/nagios/etc/nagios.cfg

Service Check Timeout
Format: service_check_timeout=<seconds>
Example: service_check_timeout=60
Host Check Timeout
Format: host_check_timeout=<seconds>
Example: host_check_timeout=120

Code: Select all

vi /usr/local/ncpa/etc/ncpa.cfg

host_check_timeout=30
service_check_timeout=120

Bump the timeouts up by 60 seconds and then check to see how things look. Restart the ncpa_listener.service and nagios.service.

We also see that Performance data throwing a lot of errors and want to have you clean that up too.

Check to see if any config throwing error:

Code: Select all

LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg

Is NPCD and crond running?

Code: Select all

service npcd status
service crond status

Code: Select all

service npcd restart
service crond status

Here are some troubleshooting docs, I'm sure you've looked at them but is it only the bandwidth graphs?

Hi Team,

we have not discovered with NCPA. Discovered with vmware wizard. As this is a esxi host. Please suggest accordingly.

Hello @Mahesh786

Thanks for following up and pointing me to the correct check. Want to run the 'check_vmware_api.pl' via command line so we can see what message results we are receiving when ran. First, let's get the version:

Code: Select all

/usr/local/nagios/libexec/check_vmware_api.pl -H adc-vmvhis-p001 -f /usr/local/nagiosxi/etc/components/vmware/adc_vmvhis_p001_auth.txt -V

Please provide the output results on these:

Code: Select all

/usr/local/nagios/libexec/check_vmware_api.pl -H adc-vmvhis-p001 -f /usr/local/nagiosxi/etc/components/vmware/adc_vmvhis_p001_auth.txt -l mem --verbose

And then we add '-t' or '--timeout' to increase the default timeout to see results:

Code: Select all

/usr/local/nagios/libexec/check_vmware_api.pl -H adc-vmvhis-p001 --timeout=120 -f /usr/local/nagiosxi/etc/components/vmware/adc_vmvhis_p001_auth.txt -l mem --verbose

Please let us know the results,
Perry
