Description Vadim Rutkovsky 2020-06-26 17:29:19 UTC
Instead of limiting a number of lines we fetch from container Insights operator should estimate how many bytes would be written (based on available log budget and number of unhealthy containers). This would ensure large log lines don't affect bundle size

Comment 1 Angelina Vasileva 2020-07-02 06:53:26 UTC
Fixed and verified in 4.6.0-0.nightly-2020-06-30-020342

1. Degrade operator so the logs will be collected (https://bugzilla.redhat.com/show_bug.cgi?id=1838973#c3)
2. Enter some pod
oc rsh prometheus-k8s-0

3. Write there something like
$ yes "Some text" | head -n 100000 > /proc/1/fd/1

4. Verify the log (in that case prometheus_current.log) doesn't exceed 100 lines or https://github.com/openshift/insights-operator/pull/128/files#diff-397c7d21d587358413d334b87528a7cbR215
