Hello.
Are there any ways to reset the Prometheus counter once?
I can do something like this, but counter will be reset on each request
loadmodule "xhttp_prom.so"
modparam("xhttp_prom",
"prom_counter", "name=mycounter;")
route {
prom_counter_reset("mycounter");
}
Otherwise, I will not receive the counter until a special and rare event
occurs.
Regards,
Marat

Hello Marat,
modparam only declares a counter because it only defines label names.
When a counter is added or reset then label values are set so the
counter is actually created.
If you want a counter to be reset once, you could use a trick. May be
setting a shared variable,
change that variable first time used and execute prom_counter_reset
inside an if to check
the value of that variable.
Sure other kamailio users could tell you other ways to initialize
something once.
Regards,
Vicente.

Hello,
you can e.g. use a timer route to periodically reset this. Or just filter for a special
custom SIP request method that you send to your server.
Cheers,
Henning

Hi, guys,
many thanks for your interesting solutions.
I have implemented Vicente's suggestion, it works as expected.
loadmodule "xhttp_prom.so"
modparam("xhttp_prom",
"prom_counter", "name=mycounter;")
modparam("pv", "shvset", "is_prometheus_init=i:0")
route {
if ($shv(is_prometheus_init) == 0) {
xlog("L_NOTICE", "Initialization of Prometheus counters\n");
prom_counter_reset("mycounter");
$shv(is_prometheus_init) = 1;
}
}
Regards,
Marat
