oraDbSysPhysReads
Module: ORADB-MIB
OID (symbolic): ORADB-MIB::oraDbSysPhysReads
OID (numeric): 1.3.6.1.4.1.111.4.1.1.1.8
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: the 'physical reads' parameter from v$sysstat
What is oraDbSysPhysReads?
This counter reports the 'physical reads' statistic from v$sysstat, the total number of data blocks read from disk rather than served from the buffer cache. It is one of the primary inputs for calculating buffer cache hit ratio, so a rising trend without a matching rise in workload can indicate the cache is too small.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.111.4.1.1.1.8 snmpwalk -v2c -c public <target> ORADB-MIB::oraDbSysPhysReads
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.111.4.1.1.1.8.1 snmpget -v2c -c public <target> ORADB-MIB::oraDbSysPhysReads.1
