Description: the 'free buffer inspected' parameter from v$sysstat
What is oraDbSysFreeBufferInspected?
This counter reports the 'free buffer inspected' statistic from v$sysstat, counting buffers a server process examined while searching for a reusable slot in the buffer cache, including dirty ones it had to skip. A value much larger than free buffer requested signals the cache is struggling to find clean buffers, often meaning DB_BLOCK_BUFFERS is undersized or checkpointing is falling behind.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.111.4.1.1.1.5 snmpwalk -v2c -c public <target> ORADB-MIB::oraDbSysFreeBufferInspected
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.111.4.1.1.1.5.1 snmpget -v2c -c public <target> ORADB-MIB::oraDbSysFreeBufferInspected.1
