Release 10.1A: OpenEdge Deployment:
Startup Command and Parameter Reference

Statistics With Cross-reference (-yx)

Use Statistics with Cross-reference (-yx) to collect procedure call statistics and write them to an output file.

Operating system and syntax	UNIX Windows	-yx
Use with	Maximum value	Minimum value	Single-user default	Multi-user default
Client Session	–	–	–	–

With this parameter, you can monitor information to answer the questions:

How many calls were made in a given period of time?
How long did a procedure spend executing?
How often was a procedure swapped to and from the temporary file (SRT file)?

Progress places the default output file for the -yx parameter, proc.mon, in your current working directory. However, you can specify a different output file by using the PROCMON environment variable. Simply set PROCMON to point to the file you want to use.

For example, in a UNIX environment, if you want to use a file named stats in the /usr/tmp directory, enter the following command on the command line:

PROCMON=/usr/tmp/stats; export PROCMON

Use the SHOW-STATS statement to write the procedure call statistics to the output file. The CLEAR option sets all counters and timers (such as Calls and Time) to 0. When you exit Progress, the -yx parameter writes the procedure call statistics to the output file whether or not you use SHOW-STATS.

The following example shows sample procedure call statistics as they appear in the output file:

The fields that appear in the output file proc.mon are as follows:

Caller — The names of any calling procedures. The word <top> indicates there was no calling procedure, and you ran the called procedure directly from the Procedure Editor.
Callee — The names of the called procedures.
Load Size — The size, in bytes, of each called procedure as Progress loads it into memory.

If you see a load size of 0, the called procedure is an uncompiled source procedure (.p file), or an r-code file (.r file) that was previously loaded into memory.

Calls — The number of times the Caller procedure calls the Callee procedure.
Rd Bytes — Generally, the called procedure’s load size. However, if the procedure is swapped out of memory and later restored, Rd bytes equals the procedure’s Load Size added to the number of bytes read from the SRT file. Rd Bytes grows larger each time the procedure is swapped out of memory and restored from the SRT file.
Reread — The number of bytes Progress reads from the SRT file to restore a Caller procedure that was overwritten. Progress restores only what is necessary to continue executing the Caller procedure. In some cases, this is less than the amount swapped to the SRT file.
Time — The total execution time of the called procedure, in milliseconds.
