Nagios Support Forum

Hi Team,

I am quite unsure how to get status information of a host services over passive checking. My remotes (linux machines) are passively sending information to Nagios XI Server passively using NCPA passive service. When I clicked on my Host service status, I can see the status information to be showing "OK: No data received yet". Could you please advise if it is possible to show more information probably the agent status, version, etc ?
We have already enabled below setting :
accept_passive_host_checks=1
accept_passive_service_checks=1
check_host_freshness=1

Hello @prashant.v01

Thanks for reaching out about passive checks issue with NCPA.

To check on the NCPA version you can get that from the command line by:
Several things to check:

• Check to see if Selinux or other security applications are blocking NCPA.
• Verify the NCPA services are running:
[list]
• systemctl status ncpa_listener

[*]Run the NCPA check via command line for results:[/*]

• /usr/local/nagios/libexec/check_ncpa.py.....'with args'

[*]check to see if able to bring up NCPA web console[/*]

• https://youripaddressorhostname:5693

[/list]

What do you see in the following logs on these checks that are receiving the message "No data received yet".

Hi Perry,

Thanks for response.

I was missed to remove comment for "#[passive check] " in nrdp.cfg file. After removing the comment passive checks are worked.
