parse Metrics Operator

The parse operator parses the specified field to create new fields to use in the metrics query.

tip

If you are querying Graphite metrics, and do not specify the field to be parsed, the metric name parsed.

Each wildcard in the pattern corresponds to a specified field. The parse operator supports both lazy (shortest match) and greedy (longest match wildcard matches.  Use '*' for a lazy match, or '**' for a greedy match.

parse syntax

parse [field=FIELD] PATTERN as PARSED_FIELD [, PARSED_FIELD, ...]

Where:

  • FIELD is the metric field you want to parse, 
  • PATTERN is an expression in which wildcards indicate how to parse FIELD
  • PARSED_FIELD is a field that results from the parsing process

parse examples

parse three fields from a metric field

In this query, we parse the LoadBalancer field. The format of the field is type/name/id, for example:

app/app-song-8d/4567223890123456

This query creates a field for each of the forward-slash-separated segments:  

AvailabilityZone=us-west-1a metric=HTTPCode_Target_2XX_Count | parse field=LoadBalancer */*/* as type, name, id

The parse operator creates fields named type, name, and id that have the values from the slash-separated segments of the LoadBalancer field.

Use a parsed field in a query

You can use the field(s) you’ve parsed within the same query, after the parse operator. For example this query parses the name field out of the  LoadBalancer field, returns the average value of the HTTPCode_Target_2XX_Count metric by the name field.

AvailabilityZone=us-west-1a metric=HTTPCode_Target_2XX_Count | parse field=LoadBalancer */*/* as type, name, id | avg by name
