# Aerospike Input Plugin

The aerospike plugin queries aerospike server(s) and get node statistics & stats for
all the configured namespaces.

For what the measurements mean, please consult the [Aerospike Metrics Reference Docs](http://www.aerospike.com/docs/reference/metrics).

The metric names, to make it less complicated in querying, have replaced all `-` with `_` as Aerospike metrics come in both forms (no idea why).

All metrics are attempted to be cast to integers, then booleans, then strings.

### Configuration:
```toml
# Read stats from aerospike server(s)
[[inputs.aerospike]]
  ## Aerospike servers to connect to (with port)
  ## This plugin will query all namespaces the aerospike
  ## server has configured and get stats for them.
  servers = ["localhost:3000"]

  # username = "telegraf"
  # password = "pa$$word"

  ## Optional TLS Config
  # enable_tls = false
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
  ## If false, skip chain & host verification
  # insecure_skip_verify = true

  # Feature Options
  # Add namespace variable to limit the namespaces executed on
  # Leave blank to do all
  # disable_query_namespaces = true # default false
  # namespaces = ["namespace1", "namespace2"]

  # Enable set level telemetry
  # query_sets = true # default: false
  # Add namespace set combinations to limit sets executed on
  # Leave blank to do all sets
  # sets = ["namespace1/set1", "namespace1/set2", "namespace3"]

  # Histograms
  # enable_ttl_histogram = true # default: false
  # enable_object_size_linear_histogram = true # default: false

  # by default, aerospike produces a 100 bucket histogram
  # this is not great for most graphing tools, this will allow
  # the ability to squash this to a smaller number of buckets
  # To have a balanced histogram, the number of buckets chosen 
  # should divide evenly into 100.
  # num_histogram_buckets = 100 # default: 10
```

### Measurements:

The aerospike metrics are under a few measurement names:

***aerospike_node***: These are the aerospike **node** measurements, which are
available from the aerospike `statistics` command.

      ie,
      ```
        telnet localhost 3003
        statistics
        ...
      ```

***aerospike_namespace***: These are aerospike namespace measurements, which
are available from the aerospike `namespace/<namespace_name>` command.

      ie,
      ```
        telnet localhost 3003
        namespaces
        <namespace_1>;<namespace_2>;etc.
        namespace/<namespace_name>
        ...
      ```
***aerospike_set***: These are aerospike set measurements, which
are available from the aerospike `sets/<namespace_name>/<set_name>` command.

      ie,
      ```
        telnet localhost 3003
        sets
        sets/<namespace_name>
        sets/<namespace_name>/<set_name>
        ...
      ```
***aerospike_histogram_ttl***: These are aerospike ttl hisogram measurements, which
is available from the aerospike `histogram:namespace=<namespace_name>;[set=<set_name>;]type=ttl` command.

      ie,
      ```
        telnet localhost 3003
        histogram:namespace=<namespace_name>;type=ttl
        histogram:namespace=<namespace_name>;[set=<set_name>;]type=ttl
        ...
      ```
***aerospike_histogram_object_size_linear***: These are aerospike object size linear histogram measurements, which is available from the aerospike `histogram:namespace=<namespace_name>;[set=<set_name>;]type=object_size_linear` command.

      ie,
      ```
        telnet localhost 3003
        histogram:namespace=<namespace_name>;type=object_size_linear
        histogram:namespace=<namespace_name>;[set=<set_name>;]type=object_size_linear
        ...
      ```

### Tags:

All measurements have tags:

- aerospike_host
- node_name

Namespace metrics have tags:

- namespace_name

Set metrics have tags:

- namespace_name
- set_name

Histogram metrics have tags:
- namespace_name
- set_name (optional)
- type
