Check Oracle status
--tns SID/IP Address
Check remote TNS server
--db SID
Check remote database (search /bin/ps for PMON process)
--sessions SID
Check remote database concurrent active sessions
--asessions SID
Count sessions on the database (either active or not) per database user
--login SID
Attempt a dummy login and alert if not ORA-01017: invalid username/password
--userslocked SID
Check if there's any user account is locked
--cache
Check remote database for library and buffer cache hit ratios
--parsing
Check remote database for Soft/Hard parse ratios
--tablespace
Check remote database for tablespace capacity in ORACLE_SID
--undo
Check remote database for UNDO tablespace capacity in ORACLE_SID
--fra
Check remote database for FLASH_RECOVERY_AREA capacity in ORACLE_SID
--diskgroup
Check remote database for diskgroup capacity in ORACLE_ASM_SID (Tipically +ASM1/2...)
--dgstats
Dataguard statistics (Apply & Transport Lag). This check is done ON THE STANDBY (the master does not have information on V\$DATAGUARD_STATS. So ORACLE_SID and HOSTNAME must be the STANDBY ones.
--redogen
Daily check for yesterday's redo generation
--sessionlock
Watch for session locks (any lock with return CRITICAL)
--totalspace
Total Space taken by the database Excluding sytem tablespaces.
--totalspacedelta
Delta of the Total Space (Yesterday-thedaybeforeyesterday)
--developers
Number of sessions of the developers.
--help
Print this help screen
--version
Print version and license information
If the plugin doesn't work, check that the ORACLE_HOME environment
variable is set, that ORACLE_HOME/bin is in your PATH, and the
tnsnames.ora file is locatable and is properly configured on your Oracle server.
If you want to use a default Oracle home, add in your oratab file:
*:/opt/app/oracle/product/7.3.4:N
