Hello Nagios Support

How to configure DISK Performance monitoring for Linux (NRPE agent)?

There are many checks for Windows agent (on box293 site), but none for Linux.
How to get LInux volumes monitored for Latency, Read/Write speed and similar?

Thank you.

I would suggest using NCPA as it includes performance and disk space checks.

Performance checks:

Disk free space:

Disk used space by percentage:

NCPA will get you monitoring the Linux system but you would have to add a plugin like this to monitor i/o stats

There really aren't many available for monitoring disk latency and i/o

If you are looking for just read/write time, etc. NCPA already provides that.

Hi

We are getting this error when trying to get NCPA perf monitored with XI

UNKNOWN: Error occurred while running the plugin. Use the verbose flag for more details.

Can you show us the actual check run from the command line, along with the output of it (with the verbose flag added)? We will try to recreate the issue in-house.

Hi

My bad: wrong physical disk used: it worked fine once I've realized and made configuration changes.

Sounds good! Closing the thread.
