The following files for the function of SAPOSCOL are stored in the Working Directory of SAPOSCOL :

• The file coll.put, in which SAPOSCOL writes the contents of its shared memory segment; this is performed only when SAPOSCOL is stopped and at user command
• The configuration file for monitoring selected processes, dev_proc (see Monitoring Selected Processes with SAPOSCOL)
• The file dev_filter that contains the file systems and hard disks that are not to be monitored by SAPOSCOL (see Deactivating Object Monitoring by SAPOSCOL)
• The log file dev_coll that contains SAPOSCOL messages and the status of SAPOSCOL

• The log files dev_col1 and dev_col2, which are written with a cyclical trace when SAPOSCOL is started (command saposcol –ztl)

1. The trace is first written in the file dev_col1
2. When dev_col1 exceeds a set size, the trace is written to dev_col2. The size is 50,000 lines. This number is not configurable.
3. When dev_col2 exceeds this size, dev_col1 is deleted and the trace is written to this file again.
