Nagios Support Forum

Hi,

Nagios XI Version: 2024R1.1.1
NCPA v. 3.0.1


I've installed the NCPA agent on multiple servers, and most are working and returning monitoring information. That being said, there are a handful reporting:

CRITICAL: Incorrect credentials given.

I'm entirely sure why, i've checked the ncpa.cfg file on the Windows box to make sure there are no special characters, and that it matches with what Nagios has. I've also tried manually adding it using the NCPA wizard, it recognises the box, and offers what can be monitored, but then returns the same error.

Any help would be appreciated.

Hi @greenman123, thanks for reaching out.

We currently have a ticket open for this issue.

Have you tried logging into the web UI for NCPA on these servers, with the community_string in the ncpa.cfg? Normally it is available at port 5693, so something like this...

Hello @greenman123,

By saying that there are no special characters in your community_string, are you saying that you are only using alphanumerics in your password (i.e. [0-9a-zA-Z])?
