System.Metrics.Json
Contents
Description
Encoding of ekg metrics as metricbeats compliant JSON. This module is originally from egk-json with some tweaks for metricbeats
- data BeatEvent = BeatEvent {}
- data Beat = Beat {}
- newtype BulkRequest = BulkRequest [(CreateBulk, BeatEvent)]
- newtype CreateBulk = CreateBulk {}
- sampleToJson :: Sample -> Value
- valueToJson :: Value -> Value
- sampleBeatEvents :: Store -> [Text] -> IO [BeatEvent]
- beat :: Lens' BeatEvent Beat
- timestamp :: Lens' BeatEvent POSIXTime
- beatTags :: Lens' BeatEvent [Text]
- ekg :: Lens' BeatEvent Sample
- rtt :: Lens' BeatEvent Int
- newtype Sample = Sample Sample
- newtype Value = Value Value
Converting metrics to JSON values
Types
Encode a Sample as a
metricbeat event
For reference this is the event structure

Conversion functions
sampleToJson :: Sample -> Value Source #
Generate the nested json for a Sample
Each "." in the metric name introduces a new level of nesting. For example,
the metrics [("foo.bar", 10), ("foo.baz", "label")] are encoded as
{
"foo": {
"bar": {
"type:", "c",
"val": 10
},
"baz": {
"type": "l",
"val": "label"
}
}
}valueToJson :: Value -> Value Source #
Encodes a single Value as a JSON object. Examples:
{ "count": 89460 }
{ "gauge": 300 }
