--cron

This option covers report, alert, persist and very short output suited for log file.

config file: --conf

If not provided, main config file will be searched for in /opt/cmt/conf.yml.

If the python script is used instead of the binay, the conf.yml will be the one next to the cmt.py script.

option: --report

Requires CMT to send metrology event to remote server (report to server).

Requires CMT to send Pager alert if any.

option: --persist

Requires CMT to persist some data accross consecutive runs. Not needed in CLI mode.

Some modules (may) use such data to compute delta/derivatives accross runs.

Some alert mechanisms use such data to estimate if an alert is not a transcient event.
