Oracle Tablespaces: General Information
|Distribution:||official part of Check_MK|
|Supported Agents:||Linux, HPUX, Solaris, Windows|
This check monitors the state of Oracle tablespaces. It
checks the current and maximum size, the online state
and the autoextension and optionally the setting of
the increment size.
Autoextension: During inventory the autoextension setting is determined
and remembered for later. That means that if the auto extension setting
changes later, the check will get critical. A table space may consist of
several data files with different settings. If at least one data file
has auto extension turned on, the table space is considered to have auto
extension turned on. The behaviour of autoextension setting can be configured
with a check parameter.
Increment size: If the configuration parameter
oracle_tablespaces_check_default_increment is set to
True (which is the default), then the check will warn
you, if the increment size is set to the Oracle default
value of 1 (which is generally considered as a non-optimal
State: Only table spaces in state ONLINE and READONLY
will be found by inventory and monitored. If the state changes
later, the check will not get critical. The state will
just be displayed. We assume that state changes are due
to normal operations.
Size: The logic of the size check depends on whether
autoextend is on or off. If auto extension is on, then
the still possible extensions are accounted for as free
spaces as well as the space currently free in the
data files. If auto extension is off, only the currently
free space will be honored. Table spaces in state READONLY
will not be checked for the size.
temptablespace: Ignore temporary Tablespace by default. This
can be changed when this parameter is True.
This check needs the Checkmk mk_oracle-plugin installed in
the agent. Please refer to the online documentation
for how to install that plugin.
The SID and the tablespace name, separated by a dot, for example "pengt.TEMP".
One service is created for each tablespace which is ONLINE, READONLY or OFFLINE.
