Can Jmeter only measure OS level metrics?

Question

I use JMeter for performance testing of various application, but I generally measure OS level metrics, like CPU, memory, network usages.
Can I use application specific metrics through JMeter, for example, in MySQL, I searched that following are the metrics to be monitored for performance benchmarking:

• Connection Time
• Request Statistics
• Connection Statistics
• Thread Details
• Table Lock Statistics
• Key efficiency
• Query Hit Ratio
• Query Cache Hitrate
• Replication Details
• etc.

Can these be monitored through JMeter?

Answer 1

Have a look at jmeter-plugins from Pg@gc:

• http://code.google.com/p/jmeter-plugins/

The sql query should return a single row with a single column and that value should be a number.

It will graph lines.

You can use PerfMon Pluging. Its basic monitoring, but easy to use!
