StackState Self-hosted v4.5.x
This page describes StackState v4.5.x. The StackState 4.5 version range is End of Life (EOL) and no longer supported. We encourage customers still running the 4.5 version range to upgrade to a more recent release.
Go to the documentation for the latest StackState release.
Function query
A telemetry query is a conjunction of equality conditions. E.g. name = 'system.load.norm.15' and host='localhost'. There are several builder methods available that help to refine query time range, limit the number of points returned, or set a metric field.
Telemetry.query(dataSourceName: String, query: String)
As of yet, telemetry queries only support metric queries. If you need event queries, please enter a feature request at support.stackstate.com​
Args:
dataSourceName - name of the data source.
query - set of equality conditions.
Returns:
AsyncScriptResult[TelemetryScriptApiQueryResponse]
Builder methods:
aggregation(method: String, bucketSize: String) - returns aggregated telemetry using method and bucketSize. See the available aggregation methods.
start(time: Instant) - sets the start time of the query, for example -3h.
end(time: Instant) - sets the end time of the query, for example -1h.
window(start: Instant, end: Instant) - sets query time range. Use only start to get all telemetry up to now or only end to get all telemetry up to an instant in time.
limit(points: Int) - limits the number of points returned, applicable to none aggregated queries.
metricField(fieldName: String) - optional, but may be required for some data sources. Sets a field that holds metric value.
compileQuery() - returns the telemetry query that was created with this function and the builder methods. After this builder method no more builder methods can be called.
Examples:
Get raw metric by query
Telemetry
  .query("StackState Metrics", "name='system.load.norm' and host='host1'")
  .metricField("value")
Get metric aggregated using Mean during with bucket size 1 minute:
Telemetry
  .query("StackState Metrics", "name='system.load.norm' and host='host1'")
  .metricField("value")
  .aggregation("99th percentile", "1m") // get 99th percentile of each minute
Query metrics starting 3 hours ago till now:
Telemetry
  .query("StackState Metrics", "name='system.load.norm' and host='host1'")
  .metricField("value")
  .start("-3h") // starting from 3 hours ago
Query metrics starting beginning of the data till last hour ago:
Telemetry
  .query("StackState Metrics", "name='system.load.norm' and host='host1'")
  .metricField("value")
  .end("-1h") // ending 1 hour ago
Query metrics within time range starting 3 hours ago up to 1 hour ago:
Telemetry
  .query("StackState Metrics", "name='system.load.norm' and host='host1'")
  .metricField("value")
  .window("-3h", "-1h") // from 3 hours ago to 1 hour ago
Query metrics from field "value" and limits points returned:
Telemetry
  .query("StackState Metrics", "name='system.load.norm' and host='host1'")
  .metricField("value")
  .limit(100)
Aggregation methods
The following aggregation methods are available for use with telemetry:
MEAN - mean
PERCENTILE_25 - 25 percentile
PERCENTILE_50 - 50 percentile
PERCENTILE_75 - 75 percentile
PERCENTILE_90 - 90 percentile
PERCENTILE_95 - 95 percentile
PERCENTILE_98 - 98 percentile
PERCENTILE_99 - 99 percentile
MAX - maximum
MIN - minimum
SUM - sum
EVENT_COUNT - the number of occurrences during bucket interval
SUM_NO_ZEROS - sum of the values (missing values from a data source won't be filled with zeros)
EVENT_COUNT_NO_ZEROS - the number of occurrences during bucket interval (missing values from a data source won't be filled with zeros)
