juju_statepool_report¶
juju_statepool_report shows the internal details of the pool of MongoDB sessions
used to provide MongoDB connectivity for each model. This primarily a diagnostic
tool for developers. As such, enabling the developer-mode feature flag results
in the addition of a stack trace for each pooled state showing the orign of
that state’s acquisition.
Usage¶
Must be run on a Juju controller machine.
