#3869: RTS GC Statistics from -S should be logged via the eventlog system
---------------------------------+------------------------------------------
Reporter: cjs | Owner:
Type: feature request | Status: new
Priority: normal | Component: Runtime System
Version: 6.12.1 | Keywords: gc, garbage collection,
statistics
Os: Unknown/Multiple | Testcase:
Architecture: Unknown/Multiple | Failure: None/Unknown
---------------------------------+------------------------------------------
The -Sfilename option to the RTS gives useful GC statistics, but it's hard
to correlate these with other events, particularly to see if GC is
interrupting critical sections in mutator threads. If the same information
were instead logged via the eventlog system (perhaps enabled via a "-lg"
option) one could get more insight into the garbage generation and
collection behaviour of one's program.
Note that it's probably not necessary also to store the information given
at the end of the run with both "-s" and "-S", though it may be
interesting to contemplate moving this sort of thing into the eventlog
file as well.
