Troubleshooting Channel in PARTIAL state

Why do that

The PunchPlatform command channelctl --start may report a PARTIAL state. This state indicates that one of the command (stop, start or reload) was interrupted, resulting in a channel being partially running. A typical example is to have one out of several topologies belonging to your channel not running.

This is of course serious, as your data will not be processed as you expect. A user action is necessary to check and rectify the situation.

What to do

Use the 'force' option of the PunchPlatform with the command :

channelctl stop --force

preferably on the selected channel. Next, check that the punchlines are effectively stopped in the relevant runtime, for example in the storm UI, or using the 'shiva-status' option for shiva punchlines.

Once done, restart your channels.
