show you all available statistics,
for a more simpler view try "kamctl moni". The closest thing you'll
find regards to the load are inuse transaction, or concurrent dialogs.
tmx:inuse_transactions would be more useful if it would contain an
average over some time (1-5 minutes or something like the routers have)
rather than an instantaneous value. but last time when i looked, it was
difficult to implement in k any kind of stat with average value.
perhaps that has now changed with sip router?
What I used, even in older versions,
is to combine statistics with
rtimer and htable. The statistics were just simple counters, holding
integer value, incremented/decremented as wanted.
There are some stats that just increment, practically counting different
Here is what I do if I want to get like "load" stats - i.e., number of
events in a specific period of time. For example number of 2xx
transactions per minute:
Load htable module and define a htable, say stats.
In event_route[htable:mod-init] I set $sht(stats=>2xx_transactions) = 0;
Load rtimer module to execute a route block every minute. In that route
block, do this kind of logic:
$var(stats) = $stat(2xx_transactions);
$var(diff) = $var(stats) - $sht(stats=>2xx_transactions);
$sht(stats=>2xx_transactions) = $var(stats);
- insert in db the value of $var(diff) along with the timestamp so you
have the number of transactions answered with 2xx during the last
minute. Then configure siremis to make a graph out of the db records
You can have another rtimer route executed not that often that can
delete records older than 1-2 days, so you don't fill up the database.
