Performance Plugin

[Ostermueller, Erik]

Hello,

 

I have two questions about the performance plugin.  I’ve got 1.11, Jenkins 1.590 on linux, openjdk 1.7x.

 

First, how do you delete/expire the cache that was added in V1.10 ?

 

Second, my most recent build’s .jtl file is a concatenation of the current build and multiple .jtl files from prior builds.  Is this intentional?  The concatenation doesn’t seem to happen consistently.  Without it, my throughput graphs look great.  But when my .jtl has data concatenated from multiple builds, the throughput numbers are like 0 or 1 and completely disagree with the verbose JMeter output (that looks correct to me), which is seen in the build log.

 

Thanks for Jenkins.

Replying to self here.

That was my problem and I fixed it by using the Jenkins options to delete my Jenkins "workspace" before each build.  Otherwise, JMeter's default behavior is to append new data to an existing .jtl file, no matter how old that .jtl file is.

Say that I had run builds from the 10 previous evenings, each with a 2-minute load test.

I was left with a single .jtl file that had a two minute load test followed by 23 hours and 58 minutes of inactivity...and then repeat that 9 more times.

All that inactivity graphed as near-zero throughput.
