Adjust scan performance summary logs

By default, the performance summary for hit, missed, and skipped scans is logged every 8 hours if the hit ratio (hits / (hits + misses)) drops below 0.95.

You can change scan performance summary logging in the following ways:

• Adjust the log frequency.

• Disable logging for unsolicited input points.

1. To adjust the frequency of logging using PI ICU, set its value on the Debug tab. In the startup batch file, set the perf parameter.

2. For interfaces that use unsolicited input points, deactivate performance summaries using PI ICU by going to the UniInt > Debug tab and setting Scan performance summary to 0, or specify /perf=0 in the .bat file.

   Performance summaries are meaningless for unsolicited inputs.
