Default Parameters for OraAsmDiskSpaceTest

This test closely monitors how each disk in a disk group uses the space available to it, points you to the disks that are running out of space, and thus holds a mirror to space contentions on a disk group.

This page depicts the default parameters that need to be configured for theOraAsmDiskSpaceTest.

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed. 

• By default, the USE ASM INSTANCE flag is set to Yes indicating that the eG agent extracts the metrics based on the name of the ASM instance. If you want the eG agent to extract the metrics using SID instead of the name of the ASM instance, set this flag to No.

• In order to monitor an Oracle database server, a special database user account has to be created in every Oracle database instance that requires monitoring. A Click here hyperlink is available in the test configuration page, using which a new oracle database user can be created. Alternatively, you can manually create the special database user. When doing so, ensure that this user is vested with the select_catalog_role and create session privileges.

  The sample script we recommend for user creation (in Oracle database server versions before 12c) for eG monitoring is:

  create user oraeg identified by oraeg
  create role oratest;
  grant create session to oratest;
  grant select_catalog_role to oratest;
  grant oratest to oraeg;

  The sample script we recommend for user creation (in Oracle database server 12c) for eG monitoring is:

  alter session set container=<Oracle_service_name>;
  create user <user_name> identified by <user_password> container=current default
  tablespace <name_of_default_tablespace> temporary tablespace <name_of_temporary_tablespace>;
  Grant create, session to <user_name>;
  Grant select_catalog_role to <user_name>;

  The name of this user has to be specified here. If the USE ASM INSTANCE flag is set to Yes, then, the user monitoring the Oracle database server should be vested with an additional SYSDBA privilege. To provide this privilege, do the following:

  grant sysdba to user <user_name>;

  The name of this user has to be specified here.

• Specify the password of the specified USER in the PASSWORD text box.

• Confirm the password by retyping it in the CONFIRM PASSWORD text box.

• Once the necessary values have been entered, clicking on the Update button will register the changes made.

When changing default configurations of tests, the values with "$" indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to "xyz" and $port will be changed to "80" when configuring a test.
