OVDB_STAT(8)


NAME

  ovdb_stat - Display information from the ovdb database


SYNOPSYS

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

  ovdb_stat -Hklmtv [-d database]


DESCRIPTION

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


OPTIONS

  -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).


WARNINGS

  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.
