Diagnostics allways returns success:false

[zolgera]

I have maxwell running with connection to the master and the connector is working and reacting on changes in the master (inserts, updates, deletes, ...)

I am running rabbitmq mode

The diagnostics endpoint is always returning success:false

I increased the timeout but same result

{
    "success": false,
    "checks": [
        {
            "name": "binlog-connector",
            "success": false,
            "mandatory": true,
            "resource": "mysql:3306",
            "message": "check did not return after 60000 ms"
        }
    ]
}

Tried to figure out in the sourcecode what diagnostic actually does but did not get far (java not really my thing :))

• show master status; on the master is working fine with the same user maxwell is using
  settings that I am using
• --diagnostic=true
• --http_diagnostic=true
• --binlog_heartbeat=true

EDIT:
Just saw in the readme
| /diagnostics | for kafka, send a fake message that measures the client to server latency |

So am I right that the diagnostics only works for Kafka instances?

Is there a way to see if the connection to the configured replication_host is still up or it got droped?
Like part of the healthchecks?

Is the Custom health check the only option?
