Linux Disk IOPs with SAM

Monitoring Disk I/O on Linux host is fairly trivial, provided your Linux distribution supports the UCD-DISKIO-MIB. Most Linux/Unix distributions do, including CentOS, Solaris, SUSE, and Debian. You should be able to use either SAM's SNMP Monitor or NPM's Universal Device Poller to monitor these metrics.

To add on to what ALTeReGo said:

This is also true for RedHat systems. You can verify it as follows:

1. Confirm net-snmp is installed
   1. rpm -qa |grep net-snmp
2. Confirm net-snmp has diskio built into it
   1. net-snmp-config --configure-options|grep -i diskio
3. Query the agent for diskio information
   1. snmpwalk -v1 -c public localhost 1.3.6.1.4.1.2021.13.15.1

Thank you! I wasn't aware these OIDs existed and we are now testing the servers for their existence. This will save a lot of headaches with perl programing if we do have them available.

Hi dkeyser

I know it's an old post. Did you ever end up building custom pollers for this? If you did, can you kindly upload them here

I thought I would ask before re-inventing the wheel. Thanks in advance.

For anyone looking at this information, I just uploaded custom pollers based on these OIDs
