Gauges behavior

[ipeacocks]

According to original Statsd:

If the gauge is not updated at the next flush, it will send the previous value. You can opt to send no metric at all for this gauge, by setting config.deleteGauges

https://github.com/etsy/statsd/blob/master/docs/metric_types.md#gauges

As I can see Brubeck by default doesn't send previous value if no data. Is it bug or feature? Do you have an option for changing that?

[ipeacocks]

It was my bad. Gauges are fine there.

@ipeacocks how did you solve it? I am in the same situation, brubeck sends my value just once.

[ipeacocks]

Sorry, but I dont remember.

I also ran into this problem.

In the config exists expire parameter. The documentation about it does not say anything.

This parameter indicates time expire gauge in seconds.

HTTP Endpoint GET /metric/{{metric_name}} displays status expire.

My /etc/brubeck.conf

{
  "sharding" : false,
  "server_name" : "brubeck",
  "dumpfile" : "./brubeck.dump",
  "capacity" : 15,
  "expire" : 1800,
  "http" : ":8080",

  "backends" : [
    {
      "type" : "carbon",
      "address" : "localhost",
      "port" : 2003,
      "frequency" : 10
    }
  ],

  "samplers" : [
    {
      "type" : "statsd",
      "address" : "0.0.0.0",
      "port" : 8125,
      "workers" : 3,
      "multisock" : true,
      "multimsg" : 1
    }
  ]
}

This working for me. Gauges send 30 minute.
