NAME¶

psmwatch - PSM memory partition activity monitor

SYNOPSIS¶

psmwatch shared_memory_key memory_size partition_name interval count [ verbose ]

DESCRIPTION¶

For count interations, psmwatch sleeps interval seconds and then invokes the psm_print_trace() function (see psm(3)) to report on PSM dynamic memory management activity in the PSM-managed shared memory partition identified by shared_memory_key during that interval. If the optional verbose parameter is specified, the printed PSM activity trace will be verbose as described in psm(3). To prevent confusion, the specified memory_size and partition_name are compared to those declared when this shared memory partition was initially managed; if they don't match, psmwatch immediately terminates. If interval is zero, psmwatch merely prints a current usage summary for the indicated shared-memory partition and terminates. psmwatch is helpful for detecting and diagnosing memory leaks.

EXIT STATUS¶

0

psmwatch has terminated.

FILES¶

No configuration files are needed.

ENVIRONMENT¶

No environment variables apply.

DIAGNOSTICS¶

The following diagnostics may be issued to the ion.log log file:

Can't attach to psm.

ION system error. One possible cause is that ION has not yet been initialized on the local computer; run ionadmin(1) to correct this.

Can't start trace.

Insufficient ION working memory to contain trace information. Reinitialize ION with more memory.
