Architecture

Overview

fty-metric-tpower has 1 actor:

• fty-metric-tpower-server: main actor

It also has one built-in timer, which runs each minute, sends metrics for racks/DCS which request it and reloads the topology if reconfig was pending.

Protocols

Published metrics

Agent publishes power metrics for racks and DCs:

Mailbox requests

Agent doesn't receive any mailbox requests.

Stream subscriptions

METRICS stream

If the metric is not realpower metric, ignore it.

Otherwise, check whether the metric is relevant for any known rack/DC, recompute its power metrics and publish them if asked to do so.

ASSETS stream

On any ASSET message, postpone the reconfig if we are currently in the middle of one and set the timer to the next metric publish request.
