Not showing controllers on SCI

[luis_oliveira]

Since about 10 days agora SCI is not finding controllers. We have one ZD3000 and a vSZ does someone know how to solve this?

From the side of the controllers, they are connected to SCI.

Hi Luis,

Good day to you.

This issue may happen due to many reasons as mentioned below:

1. High disk usage.

2. Storage might be high.

3. We may need to restart the docker. 

4. We may also need to Increase leap size. ( depending on the issue we see ) or We have Incomplete edit files processing.

5. Could you please confirm do we have any events like Disk usage is high ? Navigate to Admin > Status and Update > Check for Notifications if we have any such.

6. We may need screenshots of Spark Master, HDFS, Druid Coordinator, Druid Overlord from Admin > Diagnostics ( which will also give an idea on why the issue started )

This depends on the command outputs and the information mentioned above so that we can proceed with the procedure to solve or fix it.
