# Example of parsing json out of a field and modifying the metric with it.
|
|
# this is great to use in conjunction with the value parser.
|
|
#
|
|
# Example Input:
|
|
# json value="{\"label\": \"hero\", \"count\": 14}" 1465839830100400201
|
|
#
|
|
# Example Output:
|
|
# json,label=hero count=14i 1465839830100400201
|
|
|
|
load("json.star", "json")
|
|
# loads json.encode(), json.decode(), json.indent()
|
|
|
|
def apply(metric):
|
|
j = json.decode(metric.fields.get('value'))
|
|
metric.fields.pop('value')
|
|
metric.tags["label"] = j["label"]
|
|
metric.fields["count"] = j["count"]
|

return metric
