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.

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.
