The \fBlockstat\fR(1M) command is implemented as a DTrace consumer that uses the lockstat provider to gather raw data. .sp .LP The \fBlockstat\fR driver is not a public interface and you access the instrumentation offered by this provider through DTrace. Refer to the \fISolaris Dynamic Tracing Guide\fR for a description of the public documented interfaces available for the DTrace facility and the probes offered by the \fBlockstat\fR provider. .SH ATTRIBUTES .sp .LP See \fBattributes\fR(5) for a description of the following attributes: .sp .sp .TS tab() box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) .
