I am trying Log to metric conversion feature. I tried getting data in using Add Data feature. But no data preview gets displayed when the sourcetype is selected for log to metric conversion. While playing around I observed that data preview is getting displayed when METRIC-SCHEMA-TRANSFORMS Advanced setting is removed.
Here is my stanza for the sourcetype I created
[log_to_met]
DATETIME_CONFIG =
INDEXED_EXTRACTIONS = csv
LINE_BREAKER = ([\r\n]+)
METRIC-SCHEMA-TRANSFORMS = metric-schema:log_to_met_1546498662303
NO_BINARY_CHECK = true
category = Log to Metrics
pulldown_type = 1
disabled = false
transforms.conf stanza
[metric-schema:log_to_met_1546498662303]
METRIC-SCHEMA-MEASURES = _value
So, what are these Metric Measures and how to get data in with these measures. Also what is the importance of log to metric conversion.
