Hi,
I am getting the error "UNKNOWN: An error occured connecting to API. (Connection error: '[Errno 111] Connection refused')", on checking the server ncpa_listener service is not running. I tried restarting the service and reinstalling ncpa , but still service is not starting. It is a SUSE linux server (SLES 15 SPI). Please let me know how to fix the issue.
Regards,
Preethu.

Hi
Make sure port 5693 is open:
Code: Select all
firewall-cmd --add-port=5693/tcp --permanent
firewall-cmd --reload
firewall-cmd --list-ports
once that is done test by pointing your browser at [url]https://<ip%20of%20host>:5693[/url]
If that works then the Nagios XI server should be able to connect.
Let me know how it goes.
Thanks

Hi,
I have made changes on the node, and I can see ncpa_listener service is running now. But in Nagios console, I can see it is showing error status information as "CRITICAL: Incorrect credentials given." for all monitors.

Hi
On the remote machine open the file /usr/local/nagios/etc/ncpa.cfg.
Look for the line:
community_string = XXXX
and note the value of XXXX
On the XI server you can either delete the remote machine, and then run the NCPA
wizard again...
-- OR ----
You can go to Configure, Core Config Manager, and select each service of the remote server
and edit it, updating the command with the value of the token found above (XXXX)
In this example it is "mytoken":

Let me know how you make out.
Thanks
