OpenShift 3.11.x

How reproducible:
Every time

Steps to Reproduce:
1. Run application that sends 300k character long log messages
2. Look at pod logs in admin console

Actual results:
- Admin console doesn't show updated logs
- oc logs cli shows up-to-the-minute logs

Expected results:
- Same behavior

Is there an explicit character limitation for logging in the console? What additional information can I provide to determine if this is an expected failure or something we need to address?

All other pods and logging is normal, just this one with the long logs.

Comment 3 Jakub Hadvig 2020-08-31 17:44:48 UTC
There is no limitation for the character count. It's most probably due to the enormous character count for a single line.
Since there is a workaround, by using the CLI, we won't be fixing this cause the 3.11 is in maintenance mode.

Comment 6 Jakub Hadvig 2020-09-01 15:25:21 UTC
Hey Christopher,

There's no artificial per-log-message character limitation encoded in the entire log handling facility of OpenShift, so the issue is most likely in underlying technology.

> Jakub, 3.11 is in Full support until 2021 per this link [1]. Am I misreading this?

That is true, but that only stands for Security issues, which this is not.

If there is anything else I can clarify feel free to add a comment, otherwise I will close this issue in following days.
