prtloganalyzer analyzes the content of an ISIS print.prt log file for application efficiency, frequency and validity. It reads the full contents of the ISIS log file (generally named print.prt but can be changed with command line and/or IsisPreferences files) and categorizes them by application name. Runtime statistics (run time, CPU utilization and I/O time) are computed for each applicaiton. A running total for all applications as well as each unique program are maintained. The results are provided in Pvl and comma separated value (CSV) file format for easy evaluation.

The ISIS print log file contain Pvl objects that, at a minimum, describe for each program its parameters and accounting numbers for each run. Nearly all ISIS applications write to this log at the end of their execution. Here is an small example of the contents an ISIS print.prt log file:

The following table summarizes the definitions of the keywords and values found in the Results group. This group provides a count summary of applications categorized to indicate the applications processing status as found in the log file.

Results Group Keywords

Description of Results group keywords as produced by the prtloganalyzer application

Keyword	Description
Programs	Provides the total number of all applications found in the print log file.
Unique	Count of the number of unique programs found in the print log. Programs with the same name are tabulated together to form an indication of a single programs efficiency.
Included	The application provides two ways to include only named applications (see the INCLUDE and INCLUDEFROM parameters). This keyword provides a count of all the included programs analyzed.
Excluded	The application provides two ways to exclude specific applications (see the EXCLUDE and EXCLUDEFROM parameters). This keyword provides a count of all excluded programs from the print log file.
Valid	This keyword provides a count of the number of valid programs that were found in the print log file. These are application Pvl objects that do not contain an Errors group.
ZeroTime	This keyword provides a count of the number of applications that have 0 times for ConnectTime and CpuTime in the Accounting group of an application. These occurances are not included in the efficiency analysis as the statistical results are skewed by them.
NoData	There are times when an application may not contain an Accounting group. These are rare occasions and may not ever occur in the wild, but a count is provided here.
BadData	Occasionally something can go wrong with the print log file and it can become corrupted or the application did not format the contents properly. This parameter counts the number of occurances where some of the data is invalid or missing entitirely.
Total	This number provides the total number of valid programs found in the given print log file. This number includes only those used in the ProgramTotals group in the results.

The ProgramTotals group provides the runtime numbers for all the programs. This will give an indication of performance for all applications included in the analysis. The SUMMARY parameter indicates the name of a file that will included the Results and ProgramTotals groups and a ProgramTotals group for each unique set of applications, such as cam2map. The following table describes the meaning of the keywords contained in the ProgramTotals group above.

All units of times are in seconds unless otherwise indicated. All these values are computed from the Accounting group in each application object entry in the log file. These numbers are computed from keywords in this group. The ConnectTime keyword is used to compute runtime values. The CpuTime keyword is used to compute CPU values. The I/O values are computed using the difference between the connect times and the cpu times. Not real scientific but is the best we can do given the data to work with. I/O times may also include wait states during the run of the application other than disk I/O. Our assumption is that I/O dominates this difference.

ProgramTotals Group Keywords

Description of ProgramTotals group keywords as produced by the prtloganalyzer application.

Keyword	Description
Hits	Provides the total number of all applications found in the print log file. Should be the same as the Total keyword in the Results group.
ConnectTimeMinimum	Indicates the minimum time an application took to complete.
ConnectTimeMaximum	Indicates the maximum time an application took to complete.
ConnectTimeAverage	Indicates the average time an application took to complete.
ConnectTimeStdDev	Indicates the standard deviation of the time an application took to complete.
CpuTimeMinimum	Indicates the minimum cpu time an application used.
CpuTimeMaximum	Indicates the maximum cpu time an application used.
CpuTimeAverage	Indicates the average cpu time an application used.
CpuTimeStdDev	Indicates the standard deviation of the cpu time an application used.
IOTimeMinimum	Indicates the minimum I/O time an application used.
IOTimeMaximum	Indicates the maximum I/O time an application used.
IOTimeAverage	Indicates the average I/O time an application used.
IOTimeStdDev	Indicates the standard deviation of the I/O time an application used.

Finally, the name of the file specified in the LOG parameter will contain a flat file of comma separated values (CSV) for each program. This files is intended to be used to plot the computed values for each of the applications. The following is the contents of the LOG file.

As you can see the file contains certain fields from each application selected from the print log file. The name of the program is provided as well as the FROM and TO parameters to the program if they exist. It either one does not exist, a NULL values is written (some programs don't have a FROM or a TO parameter). The time the program was executed/started is also provided. This parameter provides the ability to plot a time based parameter. The connect, CPU and I/O times then follow.

Description

This parameter provides the name of the ISIS print log file. The name is typically "print.prt" but can vary. Note that many different print.prt files can be concatenated together in one file so that analysis can be performed on many files. One such way to concatenate print files is to use the UNIX cat command to combine two or more files to a single file. The general form is cat file1 file2 file3 > catfile.

Type	filename
File Mode	input
Default Path	.
Internal Default	print.prt
Filter	*.prt

Description

This parameter is optional and can be used to list the names of programs that will be included in from the print file. This is handy to limit the full-up analysis to a specific set of applications. The file should contain the name of a single application on each line.

If applications of the same name exist in the exclude list as well, exclusions always takes precedence over the inclusions.

Type	filename
File Mode	input
Internal Default	None
Filter	*.lis

Description

This parameter is optional and can be used to list the names of programs that will be excluded in from the print file. This is handy to exlude programs that are mostly benign in nature (.e.g., getkey) that may skew the analysis. The file should contain the name of a single application on each line.

If applications of the same name exist in the include list as well, exclusions always takes precedence over the inclusions.

Type	filename
File Mode	input
Internal Default	None
