labels
stage
The labels stage is an action stage that takes data from the extracted map and modifies the label set that is sent to Loki with the log entry.
Schema
labels:
# Key is REQUIRED and the name for the label that will be created.
# Value is optional and will be the name from extracted data whose value
# will be used for the value of the label. If empty, the value will be
# inferred to be the same as the key.
[ <string>: [<string>] ... ]
Examples
For the given pipeline:
- json:
expressions:
stream: stream
- labels:
stream:
Given the following log line:
{"log":"log message\n","stream":"stderr","time":"2019-04-30T02:12:41.8443515Z"}
The first stage would extract stream
into the extracted map with a value of
stderr
. The labels stage would turn that key-value pair into a label, so the
log line sent to Loki would include the label stream
with a value of stderr
.
