Dmitriy Pavlov commented on IGNITE-8138:
----------------------------------------
Was this fix reviewed by someone else?
IMO initial reason of this bug was unclear code, with magic numbers, so new
version of code still has this issue.
Why usage of org.apache.ignite.internal.util.typedef.X#timeSpan2HMSM was not
replaced to new method?
> Incorrect uptime in Ignite metrics for long running server node (1+ days)

> Ignite prints a metrics to the log with uptime, formatted as 'XX:YY:ZZ:TTT'.
> It looks, like XX corresponds to hours, YY to minutes, ZZ to seconds, however
> if we filter uptime metric from a long running server (few days), we would
> see that :
> {noformat}
> ^-- Node [id=684d2761, name=null, uptime=00:01:00:009]
> ^-- Node [id=684d2761, name=null, uptime=00:02:00:009]
> ^-- Node [id=684d2761, name=null, uptime=00:03:00:009]
> ^-- Node [id=684d2761, name=null, uptime=00:04:00:021]
> ...
> ^-- Node [id=684d2761, name=null, uptime=23:58:08:391]
> ^-- Node [id=684d2761, name=null, uptime=23:59:08:393]
> ^-- Node [id=684d2761, name=null, uptime=24:00:08:395]
> ^-- Node [id=684d2761, name=null, uptime=24:01:08:406]
> ...
> ^-- Node [id=684d2761, name=null, uptime=59:59:23:542]
> ^-- Node [id=684d2761, name=null, uptime=00:00:23:554]
> ...
> {noformat}
> BUG:
> 1. hours do not rollover at 23:59:59
> 2. there's no simple means for user to get uptime days, because hours do
> actually rollover after 59:59:59
> what is expected:
> 1. add a day counter, init with 0
> 2. make hours correctly rollover after full day (24hrs) run
> {noformat}
> ^-- Node [id=684d2761, name=null, uptime=0:00:01:00:009]
> ...

> ^-- Node [id=684d2761, name=null, uptime=1:00:00:00:009]
