When trying to remove a plugin, the application displays the error message:
An internal error has occurred, we're sorry about that
All BMC TrueSight Pulse plugins automatically install the relevant metrics, and some plugins also create dedicated dashboards, which use these metrics. When removing plugin, the application tries to remove its metrics, but this operation fails if those metrics are used by any dashboards.
This behavior is not by design, engineering has been notified and will resolve this issue shortly.
Before removing the plugin, delete its dashboards and also remove the plugin metrics from other custom dashboards, if you used the plugin metrics in other dashboards.
