Advanced I/O Monitoring 2
The PolyServe MxS Oracle Database Solution Pack (MxODM) with the
mxodmstat(8) command is the perfect compliment to the performance
monitoring tools provided by Oracle Corporation.
MxODM I/O Monitoring: Features at a Glance
PolyServe has implemented the Oracle Disk Manager specification in the
MxODM product. Not only is MxODM a complete implementation of the ODM
specification with such features as asynchronous I/O, cluster keys, and atomic file
creation, it also contains a powerful advanced I/O performance monitoring
infrastructure that accumulates very rich, informative I/O statistics.
While typical system-level I/O tools such as iostat offer little more data than the
count of device read and write operations, blocks read and written, and response
times, MxODM offers information the DBA needs. In today's complex clustered
environments, information is much more valuable than raw data when it comes
to performance monitoring.
Core Reporting Elements
The MxODM I/O monitoring package provides the following basic I/O
performance information. These reported items are referred to as the Core
Reporting Elements:
• Number of File Read and Write Operations
• Read and Write throughput per second in Kilobytes
• Count of synchronous and asynchronous I/O operations
• I/O service times
• Percentages
