Estimate archive utilization (piartool)

Examine output from the piartool -al command, as shown in the following procedure.

1. At a command prompt, go to the PI\adm directory.

2. Type the command: piartool -al.

   Output from the command lists archives in reverse chronological order (archives with newer data before archives with older data). The Used field indicates the percentage of that archive that is used.

   • For fixed sized archives, this is the percentage of the total available records in use and is an indication of how much space is available in the archive for data.

   • For dynamic archives, this is the percentage of primary records in use and is an indication of how close you are to the maximum number of points that can be created for that archive.
