.SH NAME
ziomon_zfcpdd \- monitor zfcp through blktrace drv\_data traces


.SH SYNOPSIS
.B ziomon_zfcpdd
[ \-v ] [ \-V ] [ \-h ] [ \-i \fIinterval\fR ] [ \-b \fIfile\fR ]
[ \-Q \fImsgq_path\fR \-q \fImsgq_id\fR \-m \fImsg_id\fR ]


.SH DESCRIPTION
ziomon_zfcpdd monitors performance relevant data provided by the
zfcp device driver: channel und fabric latency, QDIO outbound queue
utilisation.

ziomon_zfcpdd periodically writes statistics every time a user-sepcified
interval elapses.

ziomon_zfcpdd consumes zfcp drv\_data traces provided by the binary output
of blktrace.
