[Mono-dev] Print GC counters from a daemon

Normally, logging gc activity in real time is done by passing MONO_LOG_LEVEL=debug and MONO_LOG_MASK=gc. This will output time and memory information about each collection (minor + major). Another option, if you want to force your application to log the standard counters (obtained with --stats, that you mentioned) also on the run, and not only when the app stops, I guess you could pinvoke into the runtime (mono_counters_dump, __Internal as DllImport).

Subject: [Mono-dev] Print GC counters from a daemon
We need to regularly log some GC counters from a running application. We now enabling log on DEBUG will print it when the app stops, but we need to track it on a production server.
The following counters would help:
Minor GC time
Major GC time
Major GC time concurrent
Basically we would like to understand if we are forcing too much time in GC.
Any hints on how to print it, in case it is doable?
