Get IOPS value for Linux

Post by oakyuz »

Hi

We are using Host Monitor v9.10 on Windows 2008 SP2 (x64).

I would like to monitor the number of disk operations (i.e. IOPS value) on my Redhat systems using SNMP (net-snmp). SNMP is already configured on these systems and I can use Traffic Monitor tests without any problem. As I know, you add IN and OUT traffic in this test (two OIDs), therefore the total traffic could be obtained.

Similarly, I need to add the number of disk read and write operations to obtain disk IOPS value. I do not want to create two tests for read and write operations. Can I do this, or is there any way to accomplish my need?

I searched about net-snmp and found the followind OIDs for read and write operations:

Object Name Object Identifier
ucdDiskIOMIB ucdDiskIOMIB 1.3.6.1.4.1.2021.13.15
diskIOTable diskIOTable 1.3.6.1.4.1.2021.13.15.1
diskIOEntry diskIOEntry 1.3.6.1.4.1.2021.13.15.1.1
diskIOIndex diskIOIndex 1.3.6.1.4.1.2021.13.15.1.1.1
diskIODevice diskIODevice 1.3.6.1.4.1.2021.13.15.1.1.2
diskIONRead diskIONRead 1.3.6.1.4.1.2021.13.15.1.1.3
diskIONWritten diskIONWritten 1.3.6.1.4.1.2021.13.15.1.1.4
diskIOReads diskIOReads 1.3.6.1.4.1.2021.13.15.1.1.5
diskIOWrites diskIOWrites 1.3.6.1.4.1.2021.13.15.1.1.6


Thanks.

I am afraid we do not have solution for you (single test)

Alex

Could you consider implementing it?

It is very similar to Traffic Monitor, isn't it? I believe that disk operation is one of the major points for monitoring performance, like CPU, RAM and network traffic.

It would be nice if such a test is included in AHM.

Probably we can add some "expression" option for SNMP Get test method so several OIDs can be processed in expression like
[1.3.6.1.4.1.2021.13.15.1.1.5]+[1.3.6.1.4.1.2021.13.15.1.1.5]
