Problem to solve
Users that are already using our feature flags solution would get added value from seeing the metrics associated with the active flags that are reported by the clients. For exam[ple: When you enable a feature for a small group of users it is nice to know how many users actually get exposed to it.
Intended users
Further details
Metrics were added to Unleash 2.0. The SDK will locally collect metrics in the background and regularly share this information with the Unleash API. The API then aggregates the metrics from all clients and calculates how many times a feature toggle evaluated to enabled in a given time period.
This is the current Unleash display:
Proposal
/api/client/metrics
Send metrics
POST: http://unleash.host.com/api/client/metrics
Register a metrics payload with a timed bucket.
{
"appName": "appName",
"instanceId": "instanceId",
"bucket": {
"start": "2016-11-03T07:16:43.572Z",
"stop": "2016-11-03T07:16:53.572Z",
"toggles": {
"toggle-name-1": {
"yes": 123,
"no": 321
},
"toggle-name-2": {
"yes": 111,
"no": 0
}
}
}
}We will introduce a new tab under feature flags called "Metrics"
