ovdb_stat - Display information from the ovdb database
ovdb_stat [-Hgci] [-r artnumrange]
newsgroup [newsgroup ...]
ovdb_stat -HklmMtv [-d database]
ovdb_stat displays information from the ovdb database:
Berkeley DB statistics, newsgroup data, and overview records. The
output can optionally be in HTML format.
- -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).
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.
