Hard to view output and interpret it

[martinkennelly]

Hi,

In openshift, I am managed downstream merges and I have been frustrated trying to understand the output of the scale jobs.
One of the runs doesnt even have columns to read the data: https://prow.ci.openshift.org/view/gs/test-platform-results/pr-logs/pull/openshift_ovn-kubernetes/2750/pull-ci-openshift-ovn-kubernetes-master-qe-perfscale-aws-ovn-small-udn-density-l3/1966405141166821376

If theres a lot of data outputted in a failure, please include docs to understand the failure message when a test fails.

I see the error that is shown on the build directly and that is just part of what prow decides to show, if you show the whole lines you will see a text table output with headers and all the data, and there you can see the changepoint.
If prow has collapsed the lines into multiple lines it will be hard to see, but you can copy that to a new text file and you will get the correct output.

I'll work on adding examples to of the output to the docs.
