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.
- -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 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 DB
environment.
