Nagios XI Hardware Recomendations

[mpedros]

Here's something to help you do that: Inside the Nagios XI Configuration Wizard (Config -> Configuration Wizards) is a wizard called "Nagiostats Wizard." RUN THIS ONE! It's basically Nagios monitoring itself as a monitoring tool, as opposed to Nagios monitoring its own operating system.

Specifically, I recommend that you monitor the following:

• Average Active Host Latency
• Average Active Service Latency
• Average Host Execution Time
• Average Service Execution Time
• Active Host Checks 15min
• Active Service Checks 15min

The first two should cause alarm if they are greater than 1000ms (1 second). This means that Nagios is having problems getting host and service checks to execute.

The second two should cause alarm if they are greater than maybe 20,000ms (20 seconds). You will want to adjust this number as you add services and hosts. This indicates, on average, how long it takes to complete a host or service check.

The last two are mainly just counters that you can see over time to get an idea of how many host and service checks you are performing averaged over 15 minute intervals.

All of these data can help you with capacity planning as far as resources to add to the machine.

Good luck!

Thanks @eloyd, I really appreciate your help! Regards.
