The FairCom DB Server SNAPSHOT support collects c-tree function call counts and timings on a per-c-tree file basis. This support enhances the FairCom DB server’s existing support for collecting c-tree function call counts and timings, which are collected as totals for all files. Enabling collection of c-tree function timings now enables collection of both the total and file-specific function timings.
The ctstat utility includes a -wrktime option to enable the collection of this data. Accepted values are case sensitive and include:
on | off | reset.
Note:
ctstat -wrktime on enables the collection of function timing data; it does not generate any output.
ctstat -text is needed to see output to SNAPSHOT.FCS,
ctstat -funcfile sends per-file timings to SNAPFUNC.FCS.
ctstat -func sends the function timing output to stdout.
Example
Turn on function call timings:
# ctstat -wrktime on -u ADMIN -p ADMIN -s FAIRCOMS
Turn off function call timings:
# ctstat -wrktime off -u ADMIN -p ADMIN -s FAIRCOMS
Reset function call timings:
# ctstat -wrktime reset -u ADMIN -p ADMIN -s FAIRCOMS
Example Output in SNAPSHOT.FCS
