.SH "NAME"
ovdb_stat \- Display information from the ovdb database
.SH "SYNOPSIS"

\&\fBovdb_stat\fR [\fB\-Hgci\fR] [\fB\-r\fR \fIartnumrange\fR] \fInewsgroup\fR [\fInewsgroup\fR ...]
.PP
\&\fBovdb_stat\fR \fB\-HklmMtv\fR [\fB\-d\fR \fIdatabase\fR]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBovdb_stat\fR displays information from the ovdb database: Berkeley\ \s-1DB\s0
statistics, newsgroup data, and overview records.  The output can
optionally be in \s-1HTML\s0 format.
.PP
The number of overview records stored in the database can be obtained with the
\&\f(CW\*(C`inndf \-n\*(C'\fR command.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-g\fR" 4
.IX Item "-g"
Newsgroup high water mark, low marker mark, article count, and flag
for the given newsgroups (as stored in the ovdb \fIgroupinfo\fR database)
are displayed.
.IP "\fB\-c\fR" 4
.IX Item "-c"
Similar to \fB\-g\fR, except the high water mark, low water mark, and
article count are calculated by actually scanning the overview records
and counting them.  This can be a lengthy operation on groups with lots
of articles.
.IP "\fB\-i\fR" 4
.IX Item "-i"
Internal data regarding the given newsgroups are displayed.
.IP "\fB\-r\fR \fIartnumrange\fR" 4
.IX Item "-r artnumrange"
Overview records are retrieved.  The \fIartnumrange\fR parameter may be
a single article number, or a range of articles in the format \f(CW\*(C`low\-high\*(C'\fR.
.IP "\fB\-H\fR" 4
.IX Item "-H"
Output is presented in \s-1HTML\s0 format.
.IP "\fB\-k\fR" 4
.IX Item "-k"
Displays lock region statistics, as returned by the Berkeley\ \s-1DB\s0
\&\f(CW\*(C`lock_stat()\*(C'\fR call.
.IP "\fB\-l\fR" 4
.IX Item "-l"
Displays log region statistics, as returned by the Berkeley\ \s-1DB\s0
\&\f(CW\*(C`log_stat()\*(C'\fR call.
.IP "\fB\-m\fR" 4
.IX Item "-m"
Displays global memory pool statistics, as returned by the
Berkeley\ \s-1DB\s0 \f(CW\*(C`memp_stat()\*(C'\fR call.
.IP "\fB\-M\fR" 4
.IX Item "-M"
Same as \fB\-m\fR, and also displays memory pool statistics for each
database file.
.IP "\fB\-t\fR" 4
.IX Item "-t"
Displays log region statistics, as returned by the Berkeley\ \s-1DB\s0
\&\f(CW\*(C`txn_stat()\*(C'\fR call.
.IP "\fB\-v\fR" 4
.IX Item "-v"
Displays ovdb version, and Berkeley\ \s-1DB\s0 version.
.IP "\fB\-d\fR \fIdatabase\fR" 4
.IX Item "-d database"
Displays information about the given database, as returned by the
Berkeley\ \s-1DB\s0 \f(CW\*(C`db\->stat()\*(C'\fR call.  This operation may take a long time
on busy systems (several minutes or more).
.SH "WARNINGS"
.IX Header "WARNINGS"
\&\fBovdb_stat\fR may be safely killed with the \s-1INT, TERM,\s0 or \s-1HUP\s0 signals.
It catches those signals and exits cleanly.
Do not kill \fBovdb_stat\fR with other signals, unless absolutely necessary,
because it may leave stale locks in the database environment.
