}

An AnomalyConfig defines the bounds for which a change in a matching metric can be considered "anomalous". For metrics that are matched, we apply the anomaly config to determine whether we should create an alert.

The configuration settings defined for an anomaly configuration override defaults that are defined by the anomaly detection algorithm.

TODO(eduardoyap): Figure out default values and document them here.

type Rules 

type Rules struct {
	Match   []string `protobuf:"bytes,1,rep,name=match,proto3" json:"match,omitempty"`
	Exclude []string `protobuf:"bytes,2,rep,name=exclude,proto3" json:"exclude,omitempty"`
	// contains filtered or unexported fields
}

Rules specify how to capture traces for Anomaly Detection.

A match or exclude string must be of the string format: "{key1}={value1}&{key2=value2}&..." where key is the name of the parameter and value is the value to filter for. If a key doesn't match an actual key in the Skia DB, the alert config will simply get ignored.

For matching, if a parameter is not specified, the default value is wildcard "*", meaning match to any value. For excluding, each statement must only include a single key.

Consider the example below: 

{
  match: [
    "master=ChromiumPerf"&bot=~lacros-.*-perf&benchmark=Speedometer2",
    "master=ChromiumPerf&benchmark=Jetstream2",
  ],
  exclude: [
    "bot=lacros-eve-perf",
    "bot=lacros-x86-perf",
  ]
}

In SQL grammar, this would translate to: ... SELECT * FROM Metrics WHERE (main='ChromiumPerf' AND bot REGEXP 'lacros-.*-perf' AND benchmark='Speedometer2' AND bot!='lacros-eve-perf' AND bot!='lacros-x86-perf') OR (main='ChromiumPerf' AND benchmark='Jetstream' AND bot!='lacros-eve-perf' AND bot!='lacros-x86-perf')

	AnomalyConfigs []*AnomalyConfig `protobuf:"bytes,8,rep,name=anomaly_configs,json=anomalyConfigs,proto3" json:"anomaly_configs,omitempty"`

}

A Subscription describes a configuration through which we determine:

  • A set of metrics a group of users are interested in alert monitoring. These anomalies are grouped together into anomaly groups if they overlap.
  • Anomaly detection settings.
  • Alerting settings.
