This figure is the coordinator's measurement for the WHOLE RUN, across every droplet it held. There is no per-droplet utilization measurement; the tests timeline below is this droplet's own answer to the same question.
Phase timeline

Phase	Entered	Duration
provisioning droplet		1m 23s
installing dependencies		6.7s

build rules		40.5s
Tests on this droplet

No test attempt has been attributed to this droplet. A run whose tests have not started yet, and a run whose coordinator recorded no droplet for its attempts, both look like this.
Build log from this droplet

This run has one recorded droplet, so the whole of its build log is shown here. There is no per-droplet prefix to filter on when a run records a single droplet.
