=head1 CONFIGURATION
Make symlink:
cd /path/to/munin/etc/plugins
ln -s /path/to/munin/lib/plugins/oracle_sysstat .
ln -s /path/to/munin/lib/plugins/oracle_sysstat oracle_sysstat_asmusage # if necessary
...
The following shows example settings for this plugin:
[oracle_sysstat]
user oracle
env.ORACLE_SID ORCL
env.ORACLE_HOME /path/to/oracle/home
env.oracle_auth / as SYSDBA
[oracle_sysstat_asmusage]
user grid
env.ORACLE_SID +ASM
env.ORACLE_HOME /path/to/grid/home
env.oracle_auth / as SYSASM
env.include_module asmusage
env.plugin_name oracle_sysstat
=head1 ENVIRONMENT VARIABLES
env.ORACLE_SID:
example: env.ORACLE_SID SOMESID
default: ORCL
env.ORACLE_HOME:
example: env.ORACLE_HOME /opt/oracle/...
default: Try to find from oratab file
env.oracle_auth:
example: env.oracle_auth user/pass as SYSDBA
default: / as SYSDBA
env.exclude_module:
example: env.exclude_module asmusage tablespace
default: asmusage
Module name(s) to exclude seperated by white-space.
By default, asmusage module is excluded because another privilege
is necessary to connect ASM instance.
env.include_module:
example: env.include_module asmusage
default: none
Module name(s) to include seperated by white-space.
If both include_module and exclude_module are set, exclude will be
ignored.
env.plugin_name:
example: env.plugin_name oracle_sysstat_2
default: program name (usually oracle_sysstat)
Used for internal graph name.
It will be useful to monitor multi-instance databases.
env.db_name:
example: env.db_name dbname
default: none
Used for graph title.
It will be useful to monitor multi-instance databases.
=head1 NOTES
Uses the command "sqlplus".
Tested with Oracle Database 12c R1.
