I have seen in some usage it can take up to 15 seconds for the setting to be in place on the host Agent (meaning you can refresh the browser multiple times before it shows as being updated).

If you can confirm any behavior that takes longer we should investigate. @dikshachauhan-qasource can you time it and re-post back please?

Hi @EricDavisX ,

Specially on windows its not reflecting at all. For rest it gets updated after 2-3 mins after refreshing and updating logging level several times.

Hi @EricDavisX

UPDATE: Today while performing regression on cloud-prod environment, we observed this issue occurring here too.

@dikshachauhan-qasource with recent stability improvements it would be good to know if this was still reproducible in latest 7.13 snapshot or 8.0 snapshot code - can you re-test please? I'm logging a separate ticket for Agent continuing to go off-line/on-line which may relate to this, but we'll see.

Hi @EricDavisX

While performing testing today on 7.13BC4 build, we have observed this issue is now no more reproducible. We are now able to update Agent logging level and updated level is reflected at all places with 2 mins max.

Build details:

Kibana version: 7.13 BC4
BUILD 40749
COMMIT 5a6bad454ffe263aafed54cbd3f764253694bf37
Artifact link: https://staging.elastic.co/7.13.0-5c4bc719/summary-7.13.0.html

Hence we are closing this issue.

Thanks
