Managing Disk Space Requirements

Prism uses /usr/tmp for storing trace data files by default because that directory resides locally on each machine. For that reason, the processes that generate trace records are not slowed by writing their TNF probe records across a network connection.

You can use another directory for trace data collection files. To direct Prism to create trace data files in your chosen directory, set the PRISM_TNFDIR or TMPDIR environment variables to the directory you choose. For example,

% setenv PRISM_TNFDIR directory
