Hey all,
I was wondering if the kamctl stats output could be updated to provide a bit more parseable JSON? For instance:
# kamctl stats shmem | jq . { "jsonrpc": "2.0", "result": [ "shmem:fragments = 18", "shmem:free_size = 467187808", "shmem:max_used_size = 69694104", "shmem:real_used_size = 69683104", "shmem:total_size = 536870912", "shmem:used_size = 41048984" ], "id": 4300 }
I would hope would be more like this:
{ "jsonrpc":"2.0", "result":[ { "shmem":[ { "fragments":18, "free_size":467187808, "max_used_size":69694104, "real_used_size":69683104, "total_size":536870912, "used_size":41048984 } ] } ], "id":4300 }
I apologize in advanced because I don’t have the skillset to contribute such a feature.
Thanks!

Hello,
The jsonrpc-s module has a pretty_print option. Or is that not where you're dispatching this JSON output from?

Alex,
This is how that output was generated:
# kamctl stats shmem | jq .
Thanks!

You may want to consider an alternate and more streamlined method of pulling these.

Alex,
We are using this for time series monitoring (e.g. Zabbix). It doesn’t make sense, at least to me, to implement jsonrpc-s just to get the kamctl stats output. I mean, currently I’m just chaining the output with cut and tr, and that’s fine. I just suggest utilizing JSON a bit better here.
Thanks!

Hello,
jsonrcps is the module required by kamctl starting with version 5.0 (being the module renamed from jsonrpc-s).
Then, back to the main topic here -- the output for 'kamctl stats' was inherited from old times when MI (with no standard format in its output) was used to interact with kamailio and it was like a printed string in the form of "group.name = value" for each of the available statistics.
As I also wanted for quite long time to get a more json friendly output for stats, this discussion brought it back in my attention and I just added the rpc command stats.fetch. This one returns a json structure like in next example for getting shared memory stats:
# kamctl rpc stats.fetch shmem: { "jsonrpc": "2.0", "result": { "shmem.fragments": "1", "shmem.free_size": "64288976", "shmem.max_used_size": "2819888", "shmem.real_used_size": "2819888", "shmem.total_size": "67108864", "shmem.used_size": "2578288" }, "id": 44590 }
I left the value as string in order to accommodate large numbers (as the rpc interface works usually with integers), but if people finds it inconvenient, I can look at seeing if large numbers are actually needed here.
Cheers, Daniel

Looking to get usrloc stats in pure json format.
When trying to run from the example above:
kamctl rpc stats.fetch shmem:
I get a message of Method Not Found
Was this command not released, or is there another way to do this?
Thanks

Hello,
probably a stupid question, but do you tried to execute the command with ":" at the end? Do you get a result with kamctl rpc stats.fetch shmem?
And why are you looking into the shmem stats for usrloc statistics?
Best regards,
Henning
Point was that kamctl rpc stats.fetch usrloc or kamctl rpc stats.fetch shmem
both return
{ "jsonrpc": "2.0", "error": { "code": 500, "message": "Method Not Found" }, "id": 29575 }
shmem was the specific example given by Daniel Constantin Mierla so I'm not sure why its not working. I ended up using "kamcmd stats.get_statistics all" and parsing the raw text returned there.
