The FairCom DB Server SNAPSHOT feature supports a mode to write snapshot statistics for all files open by the FairCom DB Server to disk. Use the ctstat utility’s -file option. The snapshot statistics for all open files are then written to the SNAPFILE.FCS file in comma-delimited or human-readable format.
CSV Example
Write statistics for all open files to SNAPFILE.FCS in comma-delimited format using the ctstat utility:
# ctstat -file csv -i 1 1
