Nagios Support Forum

Hello,

I am writing a paper about monitoring tools but I can't find a lot of information about the scalability of Nagios XI. Can somebody explain to me how Nagios XI can be scaled? How many assets (devices, services, etc.) Nagios XI can support?

Another question I have is which data Nagios XI stores in the databases (Historical data). What does the historical data consist of?

I hope somebody can help me!

Thanks,
Julian

The hardware requirements page is a good place to start:

Strictly speaking, it depends. If you have 1000 checks that all require traversing entire SNMP trees, those checks will probably require more resources than 1000 checks that are querying a single OID. WMI, SNMP, NCPA/NRPE, various plugins, use of mod-gearman to distribute work, required retention periods for data/logs, just a few things that can/will influence performance.

Off the top of my head:

• Flat, plain-text logfiles
• RRDs
• MySQL database records

Thanks @mcapra!

Good luck on your paper and let us know if you have need clarification on anything or have any other questions.
