Hello Hendrik,
I was reading your post and wondering if you have made any progress on SER monitoring? Especially in regard to enhancing the snmpd to monitor the number of users and transactions?

Hello Hendrik,
What about VRRP for failover ?
SER1 (master) sip agents == || === Asterisk Farm==sip/pstn gateway SER2 (slave)

Yes I know about snmp module. There is no way to monitor SER vi snmp !?
As others have noted SER does not directly support SNMP but you can easily enhance your snmpd to support it. You add serctl fifo commands using the snmp exec directive to monitor the number of users, transactions stuff, ... The meminfo patch (now included) is handy and you can directly pipe serctl fifo meminfo into SNMP and create nifty graphs.
sipsak comes in handy, i.e. sending an OPTIONS request and measuring a) if a response comes back and b) the time processing took.
Much better would be monitoring INVITE/REGISTER response behaviour since that usually requires a whole lot more interaction (radius, db, ..) on SER side.

Hi ALL! I am trying to run some tests under sipsak but I obtain strange result I invoke sip stack with the following command: sipsak -IU -vv -s sip:sipsak@scscf.ims.touk.pl -a sipsak -l 5061 -H 192.168.0.129 The registration proces runs without any problem, user registers and then sipsak sends invite to ser. And here comes the strange thing 1. sipsak sends invite to ser: 2. Ser sends the proxy authentication required response 407 (from ngrep) 3. sipsak receives the message andresponses with the ACK???? Ive placed the ngrep from the sipsak socket in the attached file. Please help mewith this one! Best Tomasz

that looks like a bug. I'll try to look into that later. It would be great if you could try if the same behavior is still present in the latest version from subversion (let me know if I should send you a tarball of that). And the output from sipsak with -vvv would be a great help. Just send that directly to me.
Thanks Nils
I was just curious, so I took look on the ngrep....
there is short jump in the description between points 2 and 3.... 2a. sipsak sends ACK upon 407 reply, which is 100% correct 2b. sipsak resends INVITE with correct credentials 2c. ser forwards the INVITE to the sipsak @ port 5060 3. sipsak sends ACK (with the CSeq: 3, Via: headers look like combination of original ACK and passed INVITE Vias), which you've found inappropriate, right? Just to make sure we talk about the same ACK :-D
