I have a physical server with 2 disks, sda and sdb. I want to monitor their I/O and performance. The monitoring element has 3 types: ops, sps, and bps. What are these and which one is better to monitor and give me useful information?
- ops = operations per second
- sps = sectors per second
- bps = bytes per second
They each give good information. Which one is appropriate in your environment will depend on your requirements.
You can use several different ways to do this:
- As already mentioned install kind of monitoring system to get the information via kind of agent.
- To use directly
iostatprogram, store output in log and run this on some schedule
sarto keep performance information in logs (on local machine)
- Pull this information via
snmp agentinstalled on the machine
Which way you will choose depend of too many factors
