ovdb_stat - Display information from the ovdb database

CONTENTS

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

ovdb_stat -Hklmtv [-d database]

ovdb_stat displays information from the ovdb database: BerkeleyDB statistics, newsgroup data, and overview records; and optionally outputs in HTML format.

-g	Newsgroup himark, lowmark, article count, and flag for the given newsgroups (as stored in the ovdb groupinfo database) are displayed.
-c	Similar to -g, 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.
-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-hi.
-H	Output is presented in HTML format.
-k	Displays lock region statistics, as returned by the BerkeleyDB lock_stat() call.
-l	Displays log region statistics, as returned by the BerkeleyDB log_stat() call.
-m	Displays global memory pool statistics, as returned by the BerkeleyDB 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 BerkeleyDB txn_stat() call.
-v	Displays ovdb version, and BerkeleyDB version.
-d database	Displays information about the given database, as returned by the BerkeleyDB db->stat() call. This operation may take a long time on busy systems (several minutes or more).

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 DB environment.
