I ment the left side tabulation ;) It's 2 spaces per indentation leel afaict

Hello osmith, Jenkins Builder, laforge, pespin,
I'd like you to reexamine a change. Please visit
https://gerrit.osmocom.org/c/libosmocore/+/27047

core/utils.h: make use of OSMO_LIKELY in OSMO_ASSERT
Theoretically, this should improve performance of the code where
we frequently invoke OSMO_ASSERT(), like osmo-msc and osmo-bsc.

Feel free to print it as ms if value < 1000. Or print them as "X.Y s"

Hello Jenkins Builder, neels,
I'd like you to reexamine a change. Please visit
https://gerrit.osmocom.org/c/osmo-bsc/+/27081
to look at the new patch set (#6).
Change subject: WIP: New stats for lchan life duration.

WIP: New stats for lchan life duration.
This patch adds two stats which track cummulative lchan lifetime by
type TCH and SDCCH. These new counters will accomplish two things:
1) Provide a glanceable way to see if lchan durations look healthy. When
examining a site, short-lived (<5s) and long-lived (>30s) TCH lchans
are difficult to tell apart. If we only see short-lived TCH lchans,
there is most likely an RF or signaling problem to investigate. This
new counter will expose channel ages in the VTY output
2) Provide a more accurate count for Erlangs per site. Currently, we
are basing Erlangs on active TCH channel counts per stats period. This
method skews high very quickly. Each active TCH in that period
translates into the full 10s of activity. This counter should improve
accuracy by two orders of magnitude.
Approach:
- For now: a time calculation between channel activation and release
- Maybe cleaner: use osmo_time_cc

> Hi all, […]
I'm fine with tracking milliseconds, I'm not saying you should change that. I'm mentioning that I think showing milliseconds *in the VTY output* is not needed and makes stuff more difficult to read. Since VTY is to be read by a person, there's no need to see milliseconds there, and only makes it more difficult to quickly understand the duration.

Uhm sounds like I missed that part, I was just focusing on the formatting. It's probably something liek this then right?
Channel Activations:
TCH 43534 (avg lifespan 3s)
SDCCH 3214123 (avg lifespan 5s)
