It is not possible to link "Attached subscriber" and "Subscribing video" log messages

[danxuliu]

It would be useful to be able to link Attached subscriber and Subscribing video log messages, as right now it requires traversing the log back until the previous Attached subscriber message that has the same session ID as the Subscribing video message.

See the following real (with simplified session IDs) messages:

mcu_janus.go:652: Attached subscriber to room 6082999436119218 of publisher XXX in plugin janus.plugin.videoroom in session 3168146568089406 as 1807261776479180
mcu_janus.go:652: Attached subscriber to room 1221958394505625 of publisher YYY in plugin janus.plugin.videoroom in session 3168146568089406 as 5040447821437820
clientsession.go:1000: Subscribing video from XXX as 28417 in session ZZZ

This is required to then link Janus messages, like [1807261776479180] Creating ICE agent (ICE Full mode, controlling), with the subscriber.
