TUTORIAL Viewing Call Stats: Packet Loss, MOS, Buffers and more

[synack]

OK big update to the [macro-hangupcall-custom]
It was a bit of a pain as the documentation (even what is in the asterisk source code) is incorrect. I had to dig out the actual variable names from other parts of the source code.

Its quite large so i have commented out some of the database lines I feel are useless either because I only just get zeros or I just don't want them. Feel free to adjust to your own personal taste.

I cannot vouch for the validity of this data, as it's provided by the SIP channel driver.
Speaking of which, this will need to be updated/modified to work with pjsip

As always, this is beta code. It runs fine on *my* asterisk 11/freepbx 11, but use at your own caution.

synack Wow, that is amazing, that will be real handy. While you were working on this, and out of my own curiosity, does it look like something like this could be done for IAX?

Also, you have a capital 'I' in 'Time' on line 20.

Thanks, the real kudos go to the code maintainers, I just rewrapped two existing things into one new one.
Good catch thanks. I've updated the "I" above.
As for IAX, Unless I'm missing something ,no. I don't believe IAX provides the QoS statistics that the SIP or PJSIP drivers do.

 

[krzykat]

This is EXCELLENT. I think Ward should have this in by default on builds as I can't see a single negative to having access to this information. If someone didn't want all that info, you could probably use: https://www.pingman.com/kb/article/how-is-mos-calculated-in-pingplotter-pro-50.html to come up with the necessary calculation to just display the MOS.

Hat's off to Synack - There's lots of stuff out there, but those that put them together and share the info get my respect.

 

[TonyColorado]

Amazing! This works perfectly.
Confirmed working on Incredible GUI 12 running on CentOS 6.5 as well

 

[atsak]

Working on my 11/2.11 install - have IAX trunks which generates a bit of extra garbage in the log file (does not exist) but that's probably fine. Maybe a way to exit if it's IAX, not sure - no use at programming.

 

[Mike_S]

Logging this information is a great tool.
It's my understanding that when a call is placed two channels are used: The "local" channel and the "bridged" channel. Please correct me if I am wrong but this is only logging the "local" channel stats. I'm trying to find a means to log the stats from both channels. I would like this because my PBX is housed in a data center and it would be valuable to determine which leg of the call experienced issues.

I can see the information that I would like to record in the CDR using this command:

watch -n 1 'asterisk -rx "sip show channelstats"'

 

[dicko]

Unfortunately channelstats data is only available while the channel is active, look to turning on rtcp

rtcp set stats on ; for channel stats
rtcp set debug on ; for grins and info

you should see the data as it is generated in the cli;

Search google for apps that can monitor the stats data and handle/respond/report accordingly.

I guess a well constructed agi script could add whatever to your cdr reports if the earlier posts n this thread don't cover.

 

[krzykat]

Anyone having the extensions_override_freepbx working properly? on the latest incrediblepbx? Not seeing it run to populate my CDR's with lost packet stats.

 

[edlentz]

I know this is an old thread but I just found it. I appended the two files with the code and restarted Asterisk. I placed a couple of phone to phone calls. The calls appear in the CDR log and the CEL , but the additional info is missing. Where will that info be found??
Thanks

 

[kev11]

I just recently came across this thread as I was investigating on how to implement QoS for a FreePBX system. I decided to try out the update posted by synack and it works very well for the most part. Thanks for posting.

There's a small issue I need help with though. I'm able to get the statistics on the full asterisk log. However, for the master.csv log, I only get entries when a call goes into voicemail. Nothing is recorded in the userfield for an answered voice call. Would anyone be able to shed some light on this issue?

I've attached two snippets of the full log for both cases if it will help to shed some light. You'll notice that for the one that goes into voicemail appends the values in the userfield. The answered call seems to handle the stats separately and in the master.csv, the field is empty.

Where is the Master.csv file you are referencing. I applied the changes and my /var/log/asterisk/cdr-csv/Master.csv is empty

I have it both under /var/log/asterisk/cdr-csv/ and /var/log/asterisk/cdr-custom/

I achieved this by adding a custom cdr config file within the asterisk folder: /etc/asterisk/cdr_custom.conf

The contents of cdr_custom.conf below:

[mappings]
Master.csv => ${CSV_QUOTE(${CDR(clid)})},${CSV_QUOTE(${CDR(src)})},${CSV_QUOTE(${CDR(dst)})},${CSV_QUOTE(${CDR(dcontext)})},${CSV_QUOTE(${CDR(channel)})},${CSV_QUOTE(${CDR(dstchannel)})},${CSV_QUOTE(${CDR(lastapp)})},${CSV_QUOTE(${CDR(lastdata)})},${CSV_QUOTE(${CDR(start)})},${CSV_QUOTE(${CDR(answer)})},${CSV_QUOTE(${CDR(end)})},${CSV_QUOTE(${CDR(duration)})},${CSV_QUOTE(${CDR(billsec)})},${CSV_QUOTE(${CDR(disposition)})},${CSV_QUOTE(${CDR(amaflags)})},${CSV_QUOTE(${CDR(accountcode)})},${CSV_QUOTE(${CDR(uniqueid)})},${CSV_QUOTE(${CDR(userfield)})},${CDR(sequence)},${CDR(callid)},${CDR(rtcpinfo)}

kev11,
I get the same info you get, only from a call to voicemail. There is alot more info in the full log. I like they way the info is put into the userfield of the CDR. Can the other info be added to your [mappings] ? Having this in the CDR report module will be a great value for my users.

 

[edlentz]

kev11

I added your code to cdr.conf and got the info in the userfield of the cdr report. I am testing on my test system that only has one phone on it at the moment.

 

[Sergi]

Hello.
My question might seem fool, but I would like to clarify about rtpqos of CHANNEL function.
At the point of view Asterisk acting as b2bua, each two-way call, we know, has two leg: first one is when it is UAS for call initiator, and the other one - is UAC for responder (in sip terminology). Both legs have two-way media exchange with clients: transmit and receive. It's basis.
Let's take few argumets of rtpqos: "txlost" and "rxlost". Do they mean media packets to be lost between call initiator and Asterisk when they transmitting and receiving respectively?
And there is the "remote_normdevrxploss" argument for example. Whether it mean packets to lose when they are received from responder to Asterisk?
Do I understand right?
