Types of VPO Monitor Available
VPO supports the following types of threshold monitor:
❏ Monitoring With User-defined Programs or Scripts
This method uses a program or script provided by the user that is
invoked by the VPO Monitor Agent (opcmona). It collects the
monitored value and transmits it to the VPO management server
using the opcmon(1|3) C library API or command.
Monitoring Performance Metrics
Performance metrics are collected by way of the embedded
performance component. Use the following syntax in the Monitor
Program or MIB ID field:
OVPERF\\<data source>\\<object>\\<metric>
Where:
<data source> Identifies the data source. When collecting metrics
from the embedded performance component
<data source> must be set to CODA.
<object> Identifies the name of the object class to be
monitored.
The performance component collects the following
object classes:
• Global (object name: GLOBAL)
• CPU (object name: CPU)
• Network interface (object name: NETIF)
• File system (object name: FS)
• Disk (object name: DISK)
<metric> Identifies the metric to be collected.
The metrics that are currently available for each object class are
described in more detail on the following Web page:
