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.
