Nagios Support Forum

I recently changed my password and now I am noticing this issue:

UNKNOWN: Login to VirtualCentre server failed: Error: Cannot complete login due to an incorrect user name or password.

Did you change the password used in your service configurations?

No, I changed my network password which I am not sure if that would affect the Nagios server, but now that is the error I get only for the ESX host.

What do you mean by your network password? Does this change directly coincide with the timestamp on your checks when they started going critical with this error?

What I mean by network password is the Active Directory authenticated password that I set to log into any server and my laptop.
Yes, it does match up with the time that I changed my password.

Most probably your vmware checks look something like this (if you used our wizard):

/usr/local/nagios/libexec/check_esx3.pl -H "<client's IP>" -f "/usr/local/nagiosxi/etc/components/vmware/<hostname>_auth.txt" -l "CPU"

If you changed the vmware log in credentials, you need to modify the "*.auth.txt" file and enter the new credentials, so that your vmware checks won't be failing.

Hope this helps.

That didn't work. Actually the authenticated file had the username and password to what we use to log into the Nagios server as an admin. Is it possible to remove the vcenter entry and recreate it in hopes of it grabbing the correct username and password?

Yes, but you would have to rerun the wizard for the auth file to be repopulated.

This issue has also been resolved. I changed my password back to what it was.
