New parms keywords: 2014 - 2018

  • Most of these keywords control how long historical data is retained. SarCheck uses a few lightweight agents to collect data that isn't found in a system's sar reports. This retention period has always been hard coded into scripts that are analagous to the sar "sa2" script. On UNIX systems, the retention period had been set to 14 days.
  • If you don't change anything, SarCheck will behave as it always has. There is nothing that you have to do. This is all optional because we try to never change the default behavior of SarCheck.
  • This change enables you to control the argument used by the mtime parameter in the find command. It is possible to send an invalid parameter to the command, just use an integer and you'll be fine.
  • The first change on AIX: Beginning with 7.01.41 (released April 23, 2014), the data files in the ps and fs directories can be retained for as long as you want, provided you have the storage space. Just use an integer and you'll be fine. The keywords are PS_REPORT_RETENTION and FS_REPORT_RETENTION. We typically use shorter keywords but this was the suggestion from a customer and we liked it the way it was. Here's an example, to retain 30 days of reports in the ps directory, the syntax is PS_REPORT_RETENTION 30./li>
  • The change on HP-UX: Beginning with 7.01.23 (released May 1, 2014), the ps directory can be retained for as long as you want, provided you have the storage space. Just use an integer and you'll be fine. The keyword is PS_REPORT_RETENTION. Here's an example, to retain 30 days of reports in the ps directory, the syntax is PS_REPORT_RETENTION 30.
  • The change on Solaris: Beginning with 7.01.28 (released May 12, 2014), the ps and static directories can be retained for as long as you want, provided you have the storage space. Just use an integer and you'll be fine. The keywords are PS_REPORT_RETENTION and ST_REPORT_RETENTION. Here's an example, to retain 30 days of reports in the ps directory, the syntax is PS_REPORT_RETENTION 30.
  • The change on Linux: Beginning with 7.01.18 (released June 9, 2014), the ps and procstat directories can be retained for as long as you want, provided you have the storage space. Just use an integer and you'll be fine. The keywords are PS_REPORT_RETENTION and PRST_REPORT_RETENTION. Here's an example, to retain 30 days of reports in the ps directory, the syntax is PS_REPORT_RETENTION 30.
  • The second change on AIX: Beginning with 7.01.43 (released September 2, 2014) there will be an option to not produce recommendations for restricted tunable parameters. This is a bit complicated and affects a number of recommendations because of the interrelationships between multiple parameters when some are restricted and some are not. The new -ir switch does the same thing and it's an easier way to try this out.
  • Another change on Linux: Beginning with 7.01.28 (released October 25, 2017) the keyword USEIP has been added. If your Linux system does not have the ifconfig utility, this keyword will tell SarCheck to use the ip utility instead. Default behavior will not change even though ifconfig has been depreciated because we strive to keep new versions of SarCheck backward compatible with older versions to help preserve your sanity.
