sdrwatch \- SDR non\-volatile data store activity monitor
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBsdrwatch\fR \fIsdr_name\fR \fIinterval\fR \fIcount\fR [ verbose ]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
For \fIcount\fR interations, \fBsdrwatch\fR sleeps \fIinterval\fR seconds and then
invokes the \fIsdr_print_trace()\fR function (see \fIsdr\fR\|(3)) to report on \s-1SDR\s0 data
storage management activity in the \s-1SDR\s0 data store identified
by \fIsdr_name\fR during that interval.  If the optional \fBverbose\fR
parameter is specified, the printed \s-1SDR\s0 activity trace will be verbose
as described in \fIsdr\fR\|(3).
.PP
If \fIinterval\fR is zero, \fBsdrwatch\fR merely prints a current usage summary
for the indicated data store and terminates.
.PP
\&\fBsdrwatch\fR is helpful for detecting and diagnosing storage space leaks.  For
debugging the \s-1ION\s0 protocol stack, \fIsdr_name\fR is normally \*(L"ion\*(R" but might be
overridden by the value of sdrName in the .ionconfig file used to configure
the node under study.

.SH "DIAGNOSTICS"
.IX Header "DIAGNOSTICS"
The following diagnostics may be issued to the \fBion.log\fR log file:
.IP "Can't attach to sdr." 4
.IX Item "Can't attach to sdr."
\&\s-1ION\s0 system error.  One possible cause is that \s-1ION\s0 has not yet been
initialized on the local computer; run \fIionadmin\fR\|(1) to correct this.
.IP "Can't start trace." 4
.IX Item "Can't start trace."
Insufficient \s-1ION\s0 working memory to contain trace information.  Reinitialize
\&\s-1ION\s0 with more memory.
