• Consistent Gets — The number of accesses made to the block buffer to retrieve data in a
consistent mode.
• Physical Reads — The cumulative number of blocks read from disk.
• Buffer Cache Hit Ratio — The rate at which the database goes to the buffer instead of the
hard disk to retrieve data. A low ratio suggests more RAM should be added to the system.

Table C.51. Oracle::Buffer Cache settings
9.5. Oracle::Client Connectivity
The Oracle::Client Connectivity probe determines if the database is up and capable of receiving
connections from the monitored system. This probe opens an
rhnmd
connection to the system
and issues a
sqlplus connect
command on the monitored system.
The Expected DB name parameter is the expected value of
V$DATABASE.NAME
. This value is
case-insensitive. A CRITICAL status is returned if this value is not found.
Requirements — The Red Hat Network Monitoring Daemon (
rhnmd
) must be running on the
monitored system to execute this probe. For this probe to run, the
nocpulse
user must be
granted read access to your log files.
