Flow not showing RTCP packets in some cases

[AlexeyOplachko]

In some cases "transaction" request doesn't have RTCP packets even though call has RTCP related to it. We have implemented working workaround for Messages, but it's still a case for Flow.

@hvspa can you please provide us your correlation map for SIP calls ? Looks like the issue is in your correlation mapping and not in the UI code

[hvspa]

hi ALexandr, can you please help me to find that mapping info? where is it stored? thanks

looks good, you have to receive RTCP messages in the post request. Please activate debug of homer-app and check if you don't have any errors.

[hvspa]

if you are about following setting, it is still set to debug: "system_settings": { "_comment": "loglevel can be: fatal, error, warn, info, debug, trace", "hostname": "b4966520d31a", "loglevel": "debug", "logname": "homer-app.log", "logpath": "/usr/local/homer", "logstdout": false, "uuid": "d71481eb-5c63-4d22-98f7-1ef823d3b17b" } }

and this is the error i can see in the log:

{"level":"info","module":"gorm","msg":"SELECT * FROM \"hep_proto_5_call\" WHERE (sid in ($1) and create_date between $2 and $3)","time":"2020-08-12T17:09:36Z","type":"sql"} {"level":"error","msg":"GetTransactionData: We have got error: pq: relation \"hep_proto_5_call\" does not exist","time":"2020-08-12T17:09:36Z"}

{"level":"info","module":"gorm","msg":"SELECT * FROM \"hep_proto_5_call\" WHERE (sid in ($1) and create_date between $2 and $3)","time":"2020-08-12T17:09:51Z","type":"sql"} {"level":"error","msg":"GetTransactionData: We have got error: pq: relation \"hep_proto_5_call\" does not exist","time":"2020-08-12T17:09:51Z"}

[adubovikov]

ok, please change in the settings:

{
"source_field": "data_header.callid",
"lookup_id": 5,
"lookup_profile": "call",
"lookup_field": "sid",
"lookup_range": [
-300,
200
]
},

should be:

"lookup_profile: "default"

[hvspa]

yeah, that resolved the issue, and now i am seeing RTP endpoints IPs in the flow. thanks very much. is it possible to include this setting in the default config, so we dont have to make this change manually after every install?

[adubovikov]

done.
