per component ASR/ACD and AngularJS

[David Villasmil]

Hello,

So I've made some changes to Homer, because I need (i think we all do) some out-of-the-box real ASR and ACD stats PER COMPONENT.

- I've patched sipcapture.c in kamailio (now included in version 5) to expose src_ip and dst_ip pvs, in order to get the real source and destination ip address of the packets.

- I've created a view in mysql called dispatcher and I'm using the dispatcher module to find out if both src_ip and dst_ip are included in the "alias" table.

- Whenever a call is received, lookup using dispatcher the src_ipo and dst_ip, if BOTH are there then:

I changed my kamailio cfg in order to store in a mem table the status of calls:

Create record for every tracked call in a MEMORY table (following Homer's philosophy)  when the following happens:

• When an INVITE is received, insert the call info
• When a final REPLY is received:
  • if Status = 1XX set the status_code field
  • if Status = 200 set the datetime_answer with NOW()
  • if Status is [3456]XX set the dateim_end and the sip_reason fiel. (datetime_answer should be empty)
• When a BYE is received, set datetime_end, sip_reason.

Caveats:

There are cases to take into account:

• Calls which dies without a BYE.
• Calls which weren't processed properly
  • hack attempts, which do not go farther than 407 because the hacker doesn't try to authorize
  • INVITE's sent out but the client couldn't be reached

For these cases, whether to account for them or remove them, is to be decided,  for the PoC they are removed after 2 hours.

- When the stats timer fires, I compile all the info and insert it in a stats table.

The end result is aa follows:

It works pretty well.

I want to do a PR for this, the problem I'm having is with AngularJS (although i've been reading on it, I think the learning curve is very steep and it will take me a while to be able to do this), I don't know the first thing about it and I would like to show this info like the sipcapture results grid, possibly with a filter to filter by IP address.

I'm wondering if anyone can help me with this part?

Thanks a lot guys.

Hi David,

We'll be happy to fill in on the additional visualizations - the team here is currently working on the next HOMER UI so its a great time to add stuff.

Feel free to send a PR for the backend components, and we'll attache them to the rest.

Thanks!

Kind Regards,

Hello All,

I just made 2 P/Rs for the "Per component ASR/ACD":

https://github.com/sipcapture/homer-docker/pull/44

https://github.com/sipcapture/homer-api/pull/155

For https://github.com/sipcapture/homer-api/pull/155: 

- Added 1 new table on schema_configuration called: version which is needed by kamailio's dispatcher module.

- Added 1 View on schema_configuration called dispatcher_module which returns a view of the table "alias" that can be used by kamailio's dispatcher module.

For https://github.com/sipcapture/homer-docker/pull/44

- I changed kamalio.cfg to use the dispatcher module to look for BOTH sides of a SIP dialog, if both IPs are found, this call will be trcked to get ASR/ACD.

- Changed everything/Dockerfile to install kamailio from "nightly" repository as the 2 pvs used for this feature are not yet in 5 (only one is)

- Changed webapp/Dockerfile to clone homer-api from my fork, this needs to be changed back to wherever the merged P/R is.

I hope I was clear enough :)

Thanks for everything guys, hope you like it!

Has anyone looked into this?

[Alexandr Dubovikov]

Hi David,

many thank for your PR. This very interesting way to do ASR/NER calculation, unfortunately, this requires some corrections:

First, you have changed the default templates variables to hardcoded strings and of course it not acceptable

https://github.com/sipcapture/homer-docker/pull/44/commits/867436c0cc09bba873d68c6386f82f5e529b642b#diff-4c7fede89cba63d50695861d9050a2a1L11

The second part, there is a white space and tabulations changes, this should be applied like a separate PR.

and the last part: why do you prefer to use the dispatcher module for this?  IMHO the best way if you will get ASR for all IP ?

Wbr,

Alexandr

Hello Alex,

Problem of getting a global ASR/ACD is that is masks possible problems, i.e.: let's say you have a load balanced architecture, and 1 gw has 60% asr while the other has 30%, depending on quantity of calls, you may not notice one gw is failing because the 2 compensate each other.

This of course also applies to ACD as well.

I think it's much better to have a drill-down of network performance per component out-of-the-box, you'll get more detailed info.

I will take a look at what you're pointing out.

Regards,

David
