Monitoring ASM instances

Automatic Storage Management (ASM) is a feature of Oracle that you can use as a volume manager to manage and store Oracle database files, redo log files, control files, and archive log files. PATROL for Oracle monitors configured ASM instances, providing data for:

ASM instances
Online disk group for each monitored ASM instance
Parameters related to disk group space
Opened or cached online disks under each disk group
Parameters related to disk space

Note

For monitoring ASM instances, the PATROL OS account must have one of these primary group: DBA, ASMADMIN, ASMDBA, ASMOPER group.

During ASM instance configuration, the ORACLE_ASM KM discovers and monitors the diskgroups in the MOUNT state. After the configuration is complete, the KM monitors all states of the discovered diskgroups with the DiskGroupStatus parameter. Also, the KM discovers any newly added diskgroups in the MOUNT state during subsequent polling intervals.
If the Oracle Instance is using ASM, make sure that the following SQL*PLUS query does not return a 0 value:

export ORACLE_SID=xxxx

export ORACLE_HOME=/xx/xxxx/xxxxx/xxxxxx

export PATH=$PATH:$ORACLE_HOME/bin

sqlplus mon_account/password

SQL>select count(*) from v$asm_diskgroups_stat;

For each ASM instance, you must configure the instance from the ORACLE_ASM icon.
