Description

I tried to configure the metadata channel for UST. After that I get an error when listing the session.
Could someone please verify this? See below for the commands I used and the error message.

This problem happens also with LTTng Tools 2.6 RC1.

Many thanks in advance!

Best Regards
Bernd

Hi Bernd,

I can confirm that I observe the same behavior here with lttng-tools HEAD. The list command seems to be the culprit here. We will investigate.

Thanks

This bug seems to be a current limitation of the "hackish" metadata channel. If you configure the metadata channel and don't have any other channels enabled, the list command will fail.

One workaround is to enable an event prior to the configuration of the metadata channel. The enabling of any event will create the default "channel0".

We will investigate a proper fix for this issue.
