Hello Igor,
hard to say 100%, because it could be also caused from another module (the snmp modules also takes data from other sources I think).
Generally, I would always of course recommended to use a maintained version in production.
Cheers,
Henning

Hello Henning,
Thank you for your check.
Do you mean that even if we upgrade to the latest branch, we will probably face the same issue?
Regards,
Igor.

Hello Igor,
this sounds like a bug to me. The 5.6.x branch is not supported anymore, but after I a quick look I did not spotted any recent bugfixes in the modules that could match.
Cheers,
Henning

Subject: [SR-Users] Module snmpstats reporting inconsistent call success metrics on intense peaks of failed calls
Hello!
We are plotting the call success rate on each of our proxies.
Using the Kamailio snmpstats module, we try to obtain three counters to plot them on a graph:
Total Calls
Active Calls
Error Calls
Most of the time, everything works well, and we obtain sensible values:
snmpwalk -c mycommunity -v 2c W.X.Y.Z 1.3.6.1.4.1.34352.3.1.3.1.3.2 -O n
.1.3.6.1.4.1.34352.3.1.3.1.3.2.1.0 = Gauge32: 309 -> Total Calls
.1.3.6.1.4.1.34352.3.1.3.1.3.2.2.0 = Gauge32: 95 -> Active Calls
.1.3.6.1.4.1.34352.3.1.3.1.3.2.3.0 = Gauge32: 214 -> Error calls
However, when our proxies are facing intense peaks of failed calls in a short time span, sometimes, the "Error Calls" counter returns a value higher than "Total Calls". As a result, "Active Calls" suddenly reaches a value close to the maximum of a Gauge32 (because T o t a l C a l l s − E r r o r C a l l s < 0 ).
snmpwalk -c mycommunity -v 2c W.X.Y.Z 1.3.6.1.4.1.34352.3.1.3.1.3.2 -O n
.1.3.6.1.4.1.34352.3.1.3.1.3.2.1.0 = Gauge32: 153 -> Total Calls
.1.3.6.1.4.1.34352.3.1.3.1.3.2.2.0 = Gauge32: 4294967226 -> Active Calls
.1.3.6.1.4.1.34352.3.1.3.1.3.2.3.0 = Gauge32: 223 -> Error calls
As a result, our graphs make no more sense.
We are currently running kamailio 5.6.4.
Any idea if it's a bug or a configuration issue?
Regards,
Igor.
