ovdb_stat − Display information from the ovdb database


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

ovdb_stat −Hklmtv [−d database]


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



Newsgroup himark, lowmark, article count, and flag for the given newsgroups (as stored in the ovdb "groupinfo" database) are displayed.


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.


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".


Output is presented in HTML format.


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


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


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


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


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


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).


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.
