Hello List, I thought about some kind of Kamailio stats source (like registered users, calls active and some other things) to collect them into influx dB and draw them with grafana. How do you solved that? Timer based routes or statsd or whatever? Kind regards Karsten Horsmann

Hi, If you are aware about golang, you should probably wrote a telegraf input plugin for kamailio. Installed on kamalio's Host, telegraf will export metric to influxdb. Then you can graph it with grafana :) Regards. Le 6 déc. 2017 08:54, "Karsten Horsmann" <khorsmann(a)gmail.com> a écrit :

Hi, You can trigger kamctl and collect necessary data and then push this data to grafana. Check this script which collects data for zabbix, but logic should be same: https://gist.github.com/crashdump/7751564 With kind regards, Jurijs On Wed, Dec 6, 2017 at 10:29 AM, Loic Chabert <chabert.loic.74(a)gmail.com> wrote:

I use a mix of the above... With kamailio I export that stats I want via http: event_route[xhttp:request] { # Verify request come from localhost if(src_ip!=127.0.0.1) { xhttp_reply("403", "Forbidden", "text/html", "<html><body>Forbidden</body></html>"); xlog("L_WARN", "[HTTP] Unauthorized access from: $si\n"); exit; } # Metrics endpoint if ($hu =~ "^/statistics") { ... build a $var(metrics_json) with the metrics you want, must be JSON format ... } xhttp_reply("200", "OK", "application/json", "$var(metrics_json)"); } return; } Then in telegraf I use the httpjson module to gather the metrics: ...

Hi Joel, Hi List, Thanks for the nice ideas. We already use go-lang telegraf for collecting data. I saw an push to influx version of this "another sipserver" config. But if there is no influx the start of the server breaks. The pull or statsd method are both nice. I use webrtc on my frontend Kamailios, hopefully I can sort this out to make both available (websocket and json stats for telegraf). Thank you Joel for the nice hint. I will try this.

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", "core:drop_requests = 1634", "core:err_replies = 0", "core:err_requests = 0", "core:fwd_replies = 222", "core:fwd_requests = 140221", "core:rcv_replies = 3633129", "core:rcv_replies_18x = 153980", "core:rcv_replies_1xx = 388669", "core:rcv_replies_2xx = 2844680", "core:rcv_replies_3xx = 0", "core:rcv_replies_401 = 335571", "core:rcv_replies_404 = 1882", "core:rcv_replies_407 = 3960", "core:rcv_replies_480 = 4818", "core:rcv_replies_486 = 6734", "core:rcv_replies_4xx = 388874", "core:rcv_replies_5xx = 10410", "core:rcv_replies_6xx = 496", "core:rcv_requests = 1406155", "core:rcv_requests_ack = 200019", "core:rcv_requests_bye = 141683", "core:rcv_requests_cancel = 32887", "core:rcv_requests_info = 332", "core:rcv_requests_invite = 200125", "core:rcv_requests_message = 0", "core:rcv_requests_notify = 0", "core:rcv_requests_options = 500785", "core:rcv_requests_prack = 0", "core:rcv_requests_publish = 0", "core:rcv_requests_refer = 0", "core:rcv_requests_register = 42", "core:rcv_requests_subscribe = 0", "core:rcv_requests_update = 0", "core:unsupported_methods = 19", "dialog:active_dialogs = 27", "dialog:early_dialogs = 2", "dialog:expired_dialogs = 14", "dialog:failed_dialogs = 59781", "dialog:processed_dialogs = 197375", "dns:failed_dns_request = 5762", "httpclient:connections = 0", "httpclient:connfail = 55", "httpclient:connok = 101123", "pike:blocked_ips = 0", "shmem:fragments = 61", "shmem:free_size = 532084488", "shmem:max_used_size = 5328880", "shmem:real_used_size = 4786424", "shmem:total_size = 536870912", "shmem:used_size = 4454760", "siptrace:traced_replies = 0", "siptrace:traced_requests = 0", "sl:1xx_replies = 0", "sl:200_replies = 827319", "sl:202_replies = 0", "sl:2xx_replies = 0", "sl:300_replies = 0", "sl:301_replies = 0", "sl:302_replies = 0", "sl:3xx_replies = 0", "sl:400_replies = 83", "sl:401_replies = 0", "sl:403_replies = 1847", "sl:404_replies = 4", "sl:407_replies = 0", "sl:408_replies = 0", "sl:483_replies = 0", "sl:4xx_replies = 883", "sl:500_replies = 4", "sl:5xx_replies = 976", "sl:6xx_replies = 0", "sl:failures = 0", "sl:received_ACKs = 1634", "sl:sent_err_replies = 0", "sl:sent_replies = 831116", "sl:xxx_replies = 0", "tcp:con_reset = 0", "tcp:con_timeout = 0", "tcp:connect_failed = 0", "tcp:connect_success = 0", "tcp:current_opened_connections = 1", "tcp:current_write_queue_size = 0", "tcp:established = 2", "tcp:local_reject = 0", "tcp:passive_open = 2", "tcp:send_timeout = 0", "tcp:sendq_full = 0", "tmx:2xx_transactions = 2844324", "tmx:3xx_transactions = 0", "tmx:4xx_transactions = 709680", "tmx:5xx_transactions = 10733", "tmx:6xx_transactions = 495", "tmx:UAC_transactions = 3196487", "tmx:UAS_transactions = 3561209", "tmx:active_transactions = 6", "tmx:inuse_transactions = 7", "tmx:rpl_absorbed = 287838", "tmx:rpl_generated = 571117", "tmx:rpl_received = 3632903", "tmx:rpl_relayed = 3345065", "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}');

Hi Joel, thank you very much for the hints and the input. I am not sure if i should run that in the REQUEST, but it works for me. Only headache with that is, that i also use Websockets in my event_route. And AFAIK there is "only one" event_route[xhttp:request]. Would be nice to separate the /stats to an local bound listener without break the WS stuff. An working one is this config snipped for me: [...] event_route[xhttp:request] { set_reply_close(); set_reply_no_connect(); if ($Rp != MY_WS_PORT #!ifdef WITH_TLS && $Rp != MY_WSS_PORT #!endif ) { xlog("L_WARN", "HTTP request received on $Rp\n"); if ($sel(cfg_get.mylog.logint) > 1) { xhttp_reply("200", "OK", "text/html","<html><body>Received HTTP request to $hu from [$si:$sp] with protocol $proto</body></html>"); } else { xhttp_reply("403", "Forbidden", "", ""); } exit; } xlog("L_DBG", "HTTP Request Received\n"); xlog("L_INFO", "HTTP Request Received hu:($hu) src_ip:($src_ip)\n"); #!ifdef WITH_JSONSTATS # Metrics endpoint if ( ($src_ip == "127.0.0.1") && ($hu =~ "^/stats") ) { 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) = $var(metrics_count) + 1; } xhttp_reply("200", "OK", "application/json", "$var(metrics_json)"); exit; } #!endif if ($hdr(Upgrade)=~"websocket" && $hdr(Connection)=~"Upgrade" && $rm=~"GET") { [...] curl -s --interface lo -k https://MY-WEBRTC-IP:MY-WEBRTC-PORT/stats | jq '.' { "core-bad_URIs_rcvd": 0, "core-bad_msg_hdr": 0, "core-drop_replies": 0, "core-drop_requests": 3, "core-err_replies": 0, "core-err_requests": 0, "core-fwd_replies": 0, "core-fwd_requests": 3, "core-rcv_replies": 16, "core-rcv_replies_18x": 0, "core-rcv_replies_1xx": 3, "core-rcv_replies_2xx": 13, "core-rcv_replies_3xx": 0, "core-rcv_replies_401": 0, "core-rcv_replies_404": 0, "core-rcv_replies_407": 0, "core-rcv_replies_480": 0, "core-rcv_replies_486": 0, "core-rcv_replies_4xx": 0, "core-rcv_replies_5xx": 0, "core-rcv_replies_6xx": 0, "core-rcv_requests": 30, "core-rcv_requests_ack": 3, "core-rcv_requests_bye": 3, "core-rcv_requests_cancel": 0, "core-rcv_requests_info": 0, "core-rcv_requests_invite": 6, "core-rcv_requests_message": 0, "core-rcv_requests_notify": 0, "core-rcv_requests_options": 8, "core-rcv_requests_prack": 0, "core-rcv_requests_publish": 0, "core-rcv_requests_refer": 0, "core-rcv_requests_register": 0, "core-rcv_requests_subscribe": 0, "core-rcv_requests_update": 0, "core-unsupported_methods": 0, "dns-failed_dns_request": 0, "mysql-driver_errors": 0, "registrar-accepted_regs": 0, "registrar-default_expire": 3600, "registrar-default_expires_range": 0, "registrar-expires_range": 0, "registrar-max_contacts": 0, "registrar-max_expires": 3600, "registrar-rejected_regs": 0, "shmem-fragments": 62, "shmem-free_size": 1064748608, "shmem-max_used_size": 9040400, "shmem-real_used_size": 8993216, "shmem-total_size": 1073741824, "shmem-used_size": 5363816, "sl-1xx_replies": 0, "sl-200_replies": 17, "sl-202_replies": 0, "sl-2xx_replies": 0, "sl-300_replies": 0, "sl-301_replies": 0, "sl-302_replies": 0, "sl-3xx_replies": 0, "sl-400_replies": 0, "sl-401_replies": 0, "sl-403_replies": 0, "sl-404_replies": 0, "sl-407_replies": 3, "sl-408_replies": 0, "sl-483_replies": 0, "sl-4xx_replies": 0, "sl-500_replies": 0, "sl-5xx_replies": 0, "sl-6xx_replies": 0, "sl-failures": 0, "sl-received_ACKs": 3, "sl-sent_err_replies": 0, "sl-sent_replies": 20, "sl-xxx_replies": 0, "tcp-con_reset": 0, "tcp-con_timeout": 0, "tcp-connect_failed": 0, "tcp-connect_success": 0, "tcp-current_opened_connections": 1, "tcp-current_write_queue_size": 0, "tcp-established": 10, "tcp-local_reject": 0, "tcp-passive_open": 10, "tcp-send_timeout": 0, "tcp-sendq_full": 0, "tmx-2xx_transactions": 6, "tmx-3xx_transactions": 0, "tmx-4xx_transactions": 0, "tmx-5xx_transactions": 0, "tmx-6xx_transactions": 0, "tmx-UAC_transactions": 0, "tmx-UAS_transactions": 6, "tmx-active_transactions": 0, "tmx-inuse_transactions": 0, "tmx-rpl_absorbed": 3, "tmx-rpl_generated": 3, "tmx-rpl_received": 9, "tmx-rpl_relayed": 6 } 2018-03-15 22:21 GMT+01:00 Joel Serrano <joel(a)gogii.net>et>:

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.

This is an example: joel@sbc-dev:~$ curl -q http://127.0.0.1/statistics 2> /dev/null | python -m json.tool { "core-bad_URIs_rcvd": 0, [cut some output "tmx-rpl_received": 436444, "tmx-rpl_relayed": 379358, "tmx-rpl_sent": 489589, "usrloc-registered_users": 0 } joel@sbc-dev:~$ We have all those metrics available now in influxdb, then, as others have stated, Grafana is your best friend to make those metrics look nice. Hope these little snippets help you and anyone else getting started with Kamailio metrics. Cheers, Joel. On Wed, Dec 6, 2017 at 1:20 AM, Daniel-Constantin Mierla < miconda(a)gmail.com> wrote:

Hello, have you seen the article posted at: - https://www.kamailio.org/w/2015/03/kamailio-statsd-best-practices/ Eloy had a blog about it linked from above page.

How do you solved that? Timer based routes or statsd or whatever?

Hello Joel and List, okay i found a "maybe good" way to bind it to localhost without break WSS. Btw - if the returning lines of data within var(metrics_count) are higher than 100, the max_while_loops protection cuts off the rest.

Good stuff!! We use something similar too, so only stats served when requested on 127.0.0.1/stats while keeping websockets as usual. I’m not good with grafana but it would be nice if anyone shares some dashboard or graph ideas that make the metrics look nice ;) Joel.
