Ray command-line parameter to turn OFF monitoring completely?

How severe does this issue affect your experience of using Ray?

  • High: It blocks me to complete my task.

This is somewhat of a repeat / cross-post, extracting a question I had embedded in a recent post to the Ray Clusters category.

Question is: What is the command-line parameter to completely turn OFF anything to do with dashboard, monitoring etc.?

I am starting ray as:

$ ray --logging-level debug start --head --object-manager-port=8076 --include-dashboard=false --disable-usage-stats --object-store-memory=1073741824

I was under the impression that the combination of --include-dashboard=false --disable-usage-stats should turn OFF dashboard and relevant monitoring completely.

But I do see logs/dashboard.log and logs/dashboard_agent.log being created.

The 2nd file has several messages indicating some monitoring processes are being executed.

Due to some limitations on the platform I am trying this on, I get errors like so:

Basically, I want to disable completely the execution of monitoring stuff like dashboard/modules/reporter/reporter_agent.py.

What is the command-line option to turn these monitoring modules OFF (disable) completely?

Why aren’t the pair of --include-dashboard=false --disable-usage-stats enough to disable all this monitoring activity?

Thanks, in advance,

I don’t think there is a way to completely disable dashboard agent at the moment.

@sangcho to confirm.

Hmm if you turn off dashboard & usage stats, agent is alive, but it doesn’t really do anything meaningful, so technically you can simply ignore it.

Doing no monitoring at all is unfortunately not possible now. You should create an Github issue for this one
