Hi Nir,
typically for concise changes reviewing a single patch is way easier than
whole topic. I know vdsm developers prefer it that way, but please do
realize it is harder for “external” people to comprehend and you get less
feedback.
I see example of the new format mentioned in one commit message as a link
to pastebin. I suppose including a single line example in the commit
message itself is a bit more persistent
Just two notes - big -1 on moving the thread id further down the line.
Typically this is the only thing with some continuity, making it the most
important thing to see. Putting it at a fixed aligned position somewhere at
the beginning of the line would help a lot.
Do we switch to UTC timestamp or still want to use local time? It does
make it a bit hard to correlate with libvirt and qemu.
Lurker chiming in here ...
Using UTC is really important when correlating across multiple systems.
All of the boxes we run in production we have placed in UTC to help us
correlate events across our environment. We had no end of frustrations when
we could not find ANY logs to debug a problem due to a timezone shift.
And keep in mind, the one reviewing events in time may not be in the same
timezone as well, so the original timezone information will often get
converted to the local timezone of that reviewer.
Thanks for considering,
-peter
Thanks for the improvements!
