[SR-Users] msilo on proxy in front of registrar

2018-03-15 Thread Stefan Sayer 
Hello,

I have a bit of a strange situation where I want to add SIP MESSAGE
reliability (store and forward) for a proxy that is in front of the
(message-wise unreliable) registrar/message originator. So I m_store
MESSAGEs in the failure_route of MESSAGE requests.

By default, msilo's m_dump works only for REQUEST_ROUTE, thus I can't
use that in the 200 to REGISTER. But when I add a function to msilo
for ONREPLY_ROUTE (without the check for MESSAGE support) it works.

So, is there a reason that there's m_dump only for REQUEST_ROUTE? And,
is this:
  if ((msg->first_line).type == SIP_REQUEST)
the correct way to check whether we're handling a request or reply?

Also, is there a way to check the expires of contacts in the 200 to
REGISTER from the script, so I don't try to m_dump on de-REGISTER? Or
does this have to go into the m_dump function for the ONREPLY_ROUTE case?

Many thanks for hints!
Stefan

2018-03-15 Thread Joel Serrano 
Hi Karsten,

In my specific case, I had a requirement that it had to be compatible with
the telegraf httpjson input plugin.

Kamailio by default returns all the metrics in an array, and has a ':' in
the metric name.

Example:

{
  "jsonrpc":  "2.0",
  "result": [
"core:bad_URIs_rcvd = 26",
"core:bad_msg_hdr = 354",
"core:drop_replies = 0",

"tmx:rpl_sent = 3916182",
"usrloc:registered_users = 0"
  ],
  "id": 8362
}


That format (although correct) isn't compatible with what the httpjson
telegraf plugin expects:
https://github.com/influxdata/telegraf/tree/master/plugins/inputs/httpjson

I had to build my own JSON in a way that telegraf liked it:


jsonrpc_exec('{"jsonrpc": "2.0","method":
"stats.get_statistics","params": ["all"],"id": 1}');
$var(metrics_count) = 0;
jansson_array_size("result", $jsonrpl(body), "$var(total_metrics)");
while($var(metrics_count) < $var(total_metrics)) {
jansson_get("result[$var(metrics_count)]", $jsonrpl(body),
"$var(v)");
$var(metric_key) =
$(var(v){s.select,0,=}{s.trim}{s.replace,:,-});
$var(metric_value) = $(var(v){s.select,1,=}{s.trim});
jansson_set("integer", "$var(metric_key)",
"$var(metric_value)", "$var(metrics_json)");
$var(metrics_count) = $var(metrics_count) + 1;
}


And this is an example if the resulting JSON:

{
   "core-bad_URIs_rcvd":26,
   "core-bad_msg_hdr":354,
   "core-drop_replies":0,
   "core-drop_requests":1634,
   "core-err_replies":0,
   "core-err_requests":0,
   "core-fwd_replies":222,
   "core-fwd_requests":140287,
   "core-rcv_replies":3633735,
   "core-rcv_replies_18x":154043,
   "core-rcv_replies_1xx":388838,

Hello List,
Hello Joel,


i have now the time to implement this idea.

How you got  $var(metrics_json)  filed with the kamailio stats / whatever
internal informations?

btw i use kamailio 5.0.6 at this moment.

Thanks!

Checked with 5.1.4 about ds_is_from_list

exporting KSR.dispatcher.ds_select(...)

initializing kemi sub-module: KSR.dispatcher (dispatcher) (8/24/261)

Seems no function for check if source in dispatcher table….

[SR-Users] UAC Restore Mode

2018-03-15 Thread Duarte Rocha 
Greetings,

I have a question about the UAC module and its restore mode.

If i use the "auto" restore mode in the "restore_mode" parameter will the
entire info be saved in the From Tag for restore?

I'm asking because i will implement High Avaliability and need to know if
in event of a failure and i switch to a kamailio in a different machine i
will be able to do the To\From restore.

Thanks in advance,

Duarte Rocha
