Loki (how to get full RTCP packet)

[El Barto]

Hello.

Im new in Homer. Install Homer7 via docker as how-to described  and it works fine.

Grafana dashboard QOS RTCP show data, but can't see srcIP and dstIP. I checked Loki but it have only part of RTCP message like this:

{"sender_information":{"ntp_timestamp_sec":3893509320,"ntp_timestamp_usec":1631649485,"rtp_timestamp":14539360,"packets":90872,"octets":14539520},"ssrc":7339,"type":202,"report_count":1,"report_blocks":[{"source_ssrc":260830229,"fraction_lost":0,"packets_lost":0,"highest_seq_no":93897,"ia_jitter":159,"lsr":0,"dlsr":0}],"report_blocks_xr":{"type":0,"id":0,"fraction_lost":0,"fraction_discard":0,"burst_density":0,"gap_density":0,"burst_duration":0,"gap_duration":0,"round_trip_delay":0,"end_system_delay":0},"sdes_ssrc":7339}

But in Homer stored full data  -

{"dstIp": "192.168.2.21", "srcIp": "192.168.2.42", "dstPort": 13625, "srcPort": 59263, "protocol": 17, "captureId": "freepbx_2.21", "payloadType": 5, "timeSeconds": 1684218766, "timeUseconds": 59366, "correlation_id": "575d27b3081d7296...@192.168.2.21:5060", "protocolFamily": 2}  | {"node": "freepbx_2.21", "proto": "rtcp"} | {"sender_information":{"ntp_timestamp_sec":3893207565,"ntp_timestamp_usec":3987056796,"rtp_timestamp":2852663938,"packets":4,"octets":640},"ssrc":1603543539,"type":202,"report_count":1,"report_blocks":null,"report_blocks_xr":{"type":0,"id":0,"fraction_lost":0,"fraction_discard":0,"burst_density":0,"gap_density":0,"burst_duration":0,"gap_duration":0,"round_trip_delay":0,"end_system_delay":0},"sdes_ssrc":1603543539}

So what should i change to send that full data including srcIp\dstIp to Loki ?

Ok, answer on my question is :

 - Need patch  remotelog/loki.go

            l.entry.labels["SrcIP"] = model.LabelValue(pkt.SrcIP)
            l.entry.labels["SrcPort"] =  model.LabelValue(strconv.FormatUint(uint64(pkt.SrcPort),10))
            l.entry.labels["DstIP"] = model.LabelValue(pkt.DstIP)
            l.entry.labels["DstPort"] =  model.LabelValue(strconv.FormatUint(uint64(pkt.DstPort),10))
            l.entry.labels["CorrelationID"] = model.LabelValue(pkt.CID)

-rebuild heplify server (i have trouble with build heplify-server for docker, cause it required static linking, but its another question)

And finnaly it works, so now need  provide that data to prometheus -but its also another question.

Nice, but why are you attempting this on the mailing list? 

This would work a lot better over github issues - where the developers are and can help with code and answer questions.

The fields you're going for are HEP headed in JSON and can already be accessed through mapping.

Hello Lorenzo. Thanks for your reply.

Guess you are right i just search some place to find answers for my questions, cause not much manuals\info about homer configs.

I will be very appreciate if you give me a link where i can read about mapping

Hi, how can i add from_user to the labels of loki through mapping ?
