Hi James an Angelo,

most of the time my homer or hepic servers are in different subnets.
So that arp think sounds good to me.

@Angelo Take a look at the HEP Fidelity Proxy, it's capable to be in the middle between your kamailio and the hep-server and can store the HEP packets if your hep-server is unavailable.
After the hep-server (homer 7, hepic, whatever) is available again it sends the stored data automatically to the hep-server.

I've encountered a very similar problem in the past.The siptrace module uses UDP and does not expect a response, so it can be confusing that kamailio's behavior changes depending on whether the homer server is online.

The problem I've seen in the past is that when kamailio and a statsd server are in the same IP subnet, and the statds server goes offline, an ARP request is made whenever traffic is to be sent, and this ARP request is blocking until it times out (a few seconds). It blocks all workers because they all want to send a UDP packet and all have to wait.

If this is what's going on, then moving the siptrace server to a different subnet should resolve the problem.

Hi,

I have the exact same configuration with two workers and same syntax.
It works fine until I shut down homer. After that Kamailio stop precessing any traffic and all clients try to register as they are disconnected.

Kind Regards,
Angelo

Hi, 

try to define an extra sendsocket. 

And add an listen directive for that sendsocket.  Sorry for the formating wrote this on my smartphone. 

Works for me with an similar setup and 5.3

modparam("siptrace", "force_send_sock", "MY_LOCAL_SENDSOCK")
# local interface from where to send the duplicated traffic
modparam("siptrace", "duplicate_uri", "MY_HOMER_CAPTURE")
modparam("siptrace", "hep_mode_on", 1) # enable/disable Homer encapsulate mode
modparam("siptrace", "hep_version", 3) # HEPv3 the timestamp and capture agent ID will be included in the HEP header
modparam("siptrace", "hep_capture_id", MY_HOMER_CAPTURE_ID) # capture agent id Limitation: 32-bit for HEPv3.

modparam("siptrace", "trace_mode", 1) # default 0, if 1 then you dont need call siptrace flag or sip_trace()
#!endif

# sendsocket for homer 
#!ifdef WITH_HOMER
socket_workers=2
listen=MY_LOCAL_SENDLISTEN
#!endif

Hi,

 

Memory on the system is 8GB and on Kamailio we have SHM 4096 and PKG 32. Each of these VM handles only a few hundred of concurrent calls and each VM has a few hundred of TLS user registrations.

Kamailio uses IP to send the traffic to Homer and not domain name.

 

Any ideas how to solve this issue?

 

Kind Regards,

Angelo

Hello, 

 

Do use domain name as destination for homer?

Hello,

 

Interesting observation. Do you see anything related to this error period in the log files? Maybe out of memory errors etc..?

 

Cheers,

 

Henning

Hi,

 

Any ideas on this topic?

Anyone with same behavior?

Hi to all,

 

We have a Kamailio 5.3 that sends all traffic to a homer7 using siptrace module with parameters force_send_sock and hep_mode_on,1 and hep_version,3 and trace_mode,1. Everything works fine getting all traffic to Homer7 but, in case Homer7 is not reachable, Kamailio then no longer accepts traffic or registrations and it is like it crashes. When we revive Homer7 and is it again reachable accepting traffic, Kamailio then works again fine without any restart or actions.

Any ideas why this may be happening? Is there anything we need to add to the config to avoid this behavior as having Homer7 now is a single point of failure for Kamailio?

 

Thank you!

 

Kind Regards,

Angelo
