Nagios Support Forum

Hi,

I am trying out Nagios and Came up with some questions.

1. How do I change the password that I use for authenticating with a host? Is it possible to do that in bulk?
2. How do I change thresholds after the device was added to Nagios?
3. Can I disable all the alerts for a host?
4. what is the best practice for monitoring vCenter? Should I use NCPA? Or maybe treat it like a regular VM on ESXi host?
5. If I would like to pull all the info on a specific host so I could look into possible issues, where can I find that?

I hope that's the right place to ask these questions.

Thanks,
Isreli

Hey @ireichman!

Welcome to the forum.

Are you referring to the token or the password that you use to log in to the machine? The answer may vary depending on the operating system and agent installed. If you are trying to change the NCPA token, it is located in the configuration file. Just be sure to update it on your XI server as well! Installing NCPA

Follow the link below for more information about using the bulk modification tool in Nagios XI.
Bulk Modification Tool

You can change the threshold on a host or service by navigating to the Configure section of XI > click Core Config Manager under Advanced Configuration on the left pane > click on the host or service you want to modify a threshold for > then select the Check Settings tab.

You can acknowledge or disable alerts for that host. You can disable alerts in the Core Config Manager page for a given host, but it's under the Alert Settings tab.
Mass Acknowledge in Nagios XI

For monitoring VMware, I recommend following the document linked below.
Monitoring VMware with Nagios XI

You could pull information related to a specific host from it's configuration file or in the Core Config Manager.

I hope that helps! Let me know if you have any more questions.

Thanks @jbrunkow!
