NAME

       ovdb_stat - Display information from the ovdb database

SYNOPSIS

       ovdb_stat [-Hgci] [-r artnumrange] newsgroup [newsgroup ...]

       ovdb_stat -HklmMtv [-d database]

DESCRIPTION

       ovdb_stat displays information from the ovdb database: Berkeley DB statistics, newsgroup
       data, and overview records.  The output can optionally be in HTML format.

       The number of overview records stored in the database can be obtained with the "inndf -n"
       command.

OPTIONS

       -g  Newsgroup high water mark, low marker mark, article count, and flag for the given
           newsgroups (as stored in the ovdb groupinfo database) are displayed.

       -c  Similar to -g, 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.

       -i  Internal data regarding the given newsgroups are displayed.

       -r artnumrange
           Overview records are retrieved.  The artnumrange parameter may be a single article
           number, or a range of articles in the format "low-high".

       -H  Output is presented in HTML format.

       -k  Displays lock region statistics, as returned by the Berkeley DB "lock_stat()" call.

       -l  Displays log region statistics, as returned by the Berkeley DB "log_stat()" call.

       -m  Displays global memory pool statistics, as returned by the Berkeley DB "memp_stat()"
           call.

       -M  Same as -m, and also displays memory pool statistics for each database file.

       -t  Displays log region statistics, as returned by the Berkeley DB "txn_stat()" call.

       -v  Displays ovdb version, and Berkeley DB version.

       -d database
           Displays information about the given database, as returned by the Berkeley DB
           "db->stat()" call.  This operation may take a long time on busy systems (several
           minutes or more).

WARNINGS

       ovdb_stat may be safely killed with the INT, TERM, or HUP 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 database environment.
