.IX Title "OVDB_STAT 8"
.TH OVDB_STAT 8 "2008-04-06" "INN 2.4.5" "InterNetNews Documentation"
.SH "NAME"
ovdb_stat \- Display information from the ovdb database
.SH "SYNOPSYS"
.IX Header "SYNOPSYS"
\&\fBovdb_stat\fR \fB\-Hgci\fR [\fB\-r\fR \fIartnumrange\fR] newsgroup [newsgroup ...]
.PP
\&\fBovdb_stat\fR \fB\-Hklmtv\fR [\fB\-d\fR \fIdatabase\fR]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBovdb_stat\fR displays information from the ovdb database: BerkeleyDB
statistics, newsgroup data, and overview records; and optionally
outputs in \s-1HTML\s0 format.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-g\fR" 4
.IX Item "-g"
Newsgroup himark, lowmark, article count, and flag for the given newsgroups
(as stored in the ovdb \*(L"groupinfo\*(R" database) are displayed.
.IP "\fB\-c\fR" 4
.IX Item "-c"
Similar to \fB\-g\fR, except the himark, lowmark, and 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\-hi\*(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 BerkeleyDB \fIlock_stat()\fR
call.
.IP "\fB\-l\fR" 4
.IX Item "-l"
Displays log region statistics, as returned by the BerkeleyDB \fIlog_stat()\fR
call.
.IP "\fB\-m\fR" 4
.IX Item "-m"
Displays global memory pool statistics, as returned by the
BerkeleyDB \fImemp_stat()\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 BerkeleyDB \fItxn_stat()\fR
call.
.IP "\fB\-v\fR" 4
.IX Item "-v"
Displays ovdb version, and BerkeleyDB version.
.IP "\fB\-d\fR \fIdatabase\fR" 4
.IX Item "-d database"
Displays information about the given database, as returned by the
BerkeleyDB db\->\fIstat()\fR call.  This operation may take a long time
on busy systems (several minutes or more).
.SH "WARNINGS"
.IX Header "WARNINGS"
ovdb_stat may be safely killed with the \s-1INT\s0, \s-1TERM\s0, or \s-1HUP\s0 signals.
It catches those signals and exits cleanly.
Do not kill ovdb_stat with other signals, unless absolutely necessary,
because it may leave stale locks in the \s-1DB\s0 environment.

.IX Header "HISTORY"
