[SR-Users] Reset Prometheus counter once

[Vicente Hernando]

Hello Marat,

(my previous email did not pass moderation filter)

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.


Regards,
Vicente.
