[OpenSIPS-Users] SNMPStats - openserSIPRegCurrentUsers is always incrementing

Bogdan,
Thank you for testing this. I also have done some more tests. On a second
server I loaded Ubuntu, then OpenSIPS 1.6.4 tls. On this server I am running
a very simple config and the statistic for registrations is steady - it does
not increment. Next, I am trying to run the same very simple opensips.cfg
file on both servers and it looks like the problem is linked to something in
the more complex opensips.cfg file.
I have a theory about the difference that is making this problem happen. It
happens when the user registrations are authorised with a Radius server. The
server that has the problem is using Radius to authenticate the user. When I
change it to simple MySQL authentication then the statistic for registered
users is ok - it stays steady.
I would like to test it on our production servers (which do not use Radius)
, but they use db_mode 3 and so there are no statistics for number of
registered users.

Hi John,
I tried to reproduce this on live system and I do not see this difference:
tester001:~# opensipsctl fifo get_statistics usrloc:
usrloc:registered_users = 53
usrloc:location-users = 53
usrloc:location-contacts = 56
usrloc:location-expires = 84
tester001:~# opensipsctl ul show --brief | wc -l
54
Also running with DB mode 2.
The counter is decremented when a contact is removed from memory hash.
Regards,
Bogdan

Hi John,
So you are saying that "opensipsctl ul show" shows only 2 records while the
statistic shows more ??

Bogdan,
Here is a snippet showing the significant parts from the script that I
use for handling REGISTER requests, but I think there is only one line
that is unusual.
modparam("usrloc", "nat_bflag", 6)
modparam("usrloc", "db_mode", 2)
modparam("usrloc", "use_domain", 1)
modparam("registrar", "default_q", 800) modparam("registrar",
"received_avp", "$avp(s:rcv)")
sl_send_reply("100", "Trying");
if (client_nat_test("2")) {
setbflag(6);
fix_nated_register();
force_rport();
}
if (!aaa_www_authorize("")) {
www_challenge("","0");
exit;
};
if (!db_check_to()) {
sl_send_reply("401", "Unauthorized");
exit;
};
consume_credentials();
if (!save("location")) {
log(1, "***--REGISTER: location save failed!\n");
sl_reply_error();
}
In case the consume_credentials() function was causing the fault, I
repeated my tests with that line commented out. However, the counter
is still going up.
There is no "ul dump" option in opensipsctl, but there is a "ul show"
function. It shows the correct information:
[root at centos6v log]# opensipsctl fifo get_statistics usrloc:
usrloc:registered_users = 3
usrloc:aliases-users = 0
usrloc:aliases-contacts = 0
usrloc:aliases-expires = 0
usrloc:location-users = 3
usrloc:location-contacts = 2
usrloc:location-expires = 1
[root at centos6v log]# opensipsctl ul show

Hi John,
As the statistic is know to work well, I suspect something strange
with your setup (like re-registrations are actually new registers).
So, in the same time, please check the content of user location via:
opensipsctl ul dump
Just to see the actual records.

Bogdan

Hi Bogdan
Yes, I can confirm that registered_users shows the same value through
the fifo get_statistics request and the SNMP MIB value. The statistic
that appears to show the correct number of registered users is
usrloc:location-contacts
Here is the complete list of usrloc statistics on my test server
today
- only one UA is registered at the moment:
# opensipsctl fifo get_statistics usrloc:
usrloc:registered_users = 14
usrloc:aliases-users = 0
usrloc:aliases-contacts = 0
usrloc:aliases-expires = 0
usrloc:location-users = 14
usrloc:location-contacts = 1
usrloc:location-expires = 13
Sorry I cannot maintain the thread on this reply - I am only
receiving digests from this forum and have forgotten my login details
so cannot change it.

Hi John,
That stat is related to the internal statistic "registered_users"
provided by the usrloc module. Can you confirm that "opensipsctl fifo
get_statistics registered_users" gives thesame value as via SNMP ?

Bogdan

Using SNMPStats with version 1.6.2 of OpenSIPS, the value reported
for openserSIPRegCurrentUsers does not indicate the number of UA's
currently registered. It shows a value that is always increasing
over
time.
I am testing with 3 registered devices. There are three records in
the location table. However, openserSIPRegCurrentUsers now has a
value of
12 and it increments by 1 approximately every 20 minutes. I would
guess it is showing the cumulative total number of registrations,
not the current number of registered users.
