Request: allow detecting when hubot-slack has disconnected and will not reconnect

[mistydemeo]

Description

While hubot-slack has support for reconnecting when the connection to Slack is lost, there is a limit to the number of reconnection attempts. If several reconnection attempts fail, the bot will simply hang without a connection. This causes trouble for our process manager, since the client staying open means we don't end up automatically restart it. When this has happened for us a few times lately, we had to manually notice and restart the service in order to get it back up.

I'd like to see some form of event be emitted in this condition to allow us to determine when this has happened so that we can terminate the process and let the process manager restart it.

related: #215

it looks like at some point in this package's history, there was an environment variable used to configure whether the process would terminate in this condition, not just fire an event. should we reintroduce that configuration? fire the event? both?

It would be really nice to get this back into Hubot. We have a major issue at the moment with our hubot just disconnecting randomly from our slack, and there is no way to detect this so that we can restart the docker container it's running on.

For our hubot, I workaround at the moment with a cron script that checks the logs for the reconnect message. Then kill/restart the container 🤷‍♂

CHECK_STATUS=`docker logs $CONTAINER_ID | grep "INFO Slack client closed, waiting for reconnect" | wc -l

There's been no activity because it was never fixed. I opened this in 2018.

Hi @mistydemeo, sorry for the false alert. It was not an intentional behavior of the triage bot that we recently introduced recently. I've marked this issue as "auto-triage-skip".

Hey guys any update on this issue?

Im having the same problem.

Suddenly hubot loses connectivity to slack and nothing shows on the logs.
