Example
sum:my_metric{*}.as_count() # sum counts per-sample of `my_metric` sum:my_metric{env:prod} # `my_metric`, where tag `env=prod`
Basics
Entering Queries
There is both a JSON query (all-text), and a UI-aided query.
Notebooks: - New Notebook: - </> # on the far right of the query, this toggles interactive "json-syntax" queriesComponents
Queries have a

facet: @host, @url # provided by the application, applies to all metrics tag: status, perform_time # assigned to your specific metric when emittedtags
Datatypes
Metrics are assigned datatypes
Filters
Glob/Wildcard
You can glob-match metrics.

Tag-Search lets you conditionally match metrics by tag.
