metrics service configuration

compact_on_start

Run log compaction on service start

Default value	True
Possible values	True or False
YAML Path	metrics.compact_on_start
Key-Value Path	metrics/compact_on_start
Environment	NOC_METRICS_COMPACT_ON_START

compact_on_stop

Run log compaction on service stop

Default value	True
Possible values	True or False
YAML Path	metrics.compact_on_stop
Key-Value Path	metrics/compact_on_stop
Environment	NOC_METRICS_COMPACT_ON_STOP

flush_interval

Flushing is the process on moving collected changes from memory to persistent storage. You may loose up to flush_interval seconds of changes on unexpected crash.

To disable runtime flushing set parameter to 0. Changes will be flushed on graceful shutdown anyway.

Default value	1s
Possible values
YAML Path	metrics.flush_interval
Key-Value Path	metrics/flush_interval
Environment	NOC_METRICS_FLUSH_INTERVAL

compact_interval

Compacting is the process on aggregating the incremental changes to a larger chunks. Compacting allows to reduce disk space used by change log.

To disable runtime compacting set parameter to 0. Compacting still may be performed on service startup or shutdown when setting compact_on_start or compact_on_stop parameters.

Warning

Disabling of runtime compaction may lead to unlimited disk usages and may greatly increase the service startup time.

Default value	1s
Possible values
YAML Path	metrics.flush_interval
Key-Value Path	metrics/flush_interval
Environment	NOC_METRICS_FLUSH_INTERVAL
