9 Oracle VM Server

This chapter describes the Oracle VM Server metrics. This release of Enterprise Manager employs a new method for collecting performance metrics. To reduce load and increase scalability, metrics for the Oracle VM Server and Oracle VM Guest targets in an Oracle VM server pool are collected as part of the Oracle VM Server Pool target. However, all data are delivered to the correct targets.

For information about managing Oracle VM servers, see the Oracle Enterprise Manager Cloud Administration Guide.

9.1 Oracle VM Server Disk Activity (kb/s)

This metric is used to ”bulk” collect all disk activity-related metrics for all the Oracle VM Server targets in the Oracle VM server pool. This metric is not uploaded, but is used for alerts only. You can set separate thresholds for each Oracle VM Server using the Target ID. Different thresholds can be set for different Oracle VM Servers based on the Target ID. Only the collection schedule remains same for all the servers.

Thresholds should be defined against this metric, and the threshold values are applicable to all the Oracle VM Server targets in the server pool.

The collection schedule is governed by the schedule of the Oracle VM Server Disk Activity Scheduled metric. Any alerts generated are generated against the relevant Oracle VM Server target.

9.1.1 Disk

This metric displays the name of the disk.

9.1.2 Read Throughput (kb/s)

This metric displays the read throughput of the disk in kb/s. If unusually high values are observed, then check for crashing applications. If high values are expected, consider using high speed storage for better performance.

9.1.3 Total Throughput (kb/s)

This metric displays the total throughput of the disk in kb/s. If unusually high values are observed, then check for crashing applications. If high values are expected, consider using high speed storage for better performance.

9.1.4 Write Throughput (kb/s)

This metric displays the write throughput of the disk in kb/s. If unusually high values are observed, then check for crashing applications. If high values are expected, consider using high speed storage for better performance.

Note:

The collection schedule for Oracle VM Server Load metrics must be greater than the Oracle VM Manager statistics collection interval.

Oracle recommends setting the Oracle VM Server Load collection schedule to five times greater than the Oracle VM Manager statistics collection interval.

For example, if Oracle VM Manager statistics collection interval is defined at 100 seconds, then set the Oracle VM Server Load collection schedule to 500 seconds at a minimum.

For information about the Oracle VM Manager statistics collection interval, see Oracle VM User's Guide for Release 3.2.1.
