Change in osmo-bsc[master]: WIP: New stats for lchan life duration.

Attention is currently required from: iedemam. Hello Jenkins Builder, 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 (#2). 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 Change-Id: I1b0670c47cb5e0b7776eda89d1e71545ba0e3347 --- M include/osmocom/bsc/bts.h M include/osmocom/bsc/gsm_data.h M src/osmo-bsc/bts.c M src/osmo-bsc/bts_trx_vty.c M src/osmo-bsc/bts_vty.c M src/osmo-bsc/gsm_data.c M src/osmo-bsc/lchan_fsm.c 7 files changed, 61 insertions(+), 0 deletions(-) git pull ssh://gerrit.osmocom.org:29418/osmo-bsc refs/changes/81/27081/2 -- To view, visit https://gerrit.osmocom.org/c/osmo-bsc/+/27081 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-bsc Gerrit-Branch: master Gerrit-Change-Id: I1b0670c47cb5e0b7776eda89d1e71545ba0e3347 Gerrit-Change-Number: 27081 Gerrit-PatchSet: 2 Gerrit-Owner: iedemam &lt;michael(a)kapsulate.com&gt; Gerrit-Reviewer: Jenkins Builder Gerrit-Attention: iedemam &lt;michael(a)kapsulate.com&gt; Gerrit-MessageType: newpatchset
