Ops Center monitors the health of your operating systems and hardware. Create and configure the Ops Center Notification Profile to alert specific users to receive an notification when a threshold or parameter is crossed.
This chapter discusses the following topics:
Ops Center enables you to monitor the health of your Solaris, Linux, and Windows operating systems, including the following:
Connectivity
File system status
Monitoring variables
CPU usage
Memory usage
Network usage
When a pre-defined threshold or variable is crossed, a notification is sent. You can edit the thresholds and variables that control how OS monitoring takes place. See Monitoring an OS in the Oracle Enterprise Manager Ops Center 2.5 documentation for the procedures to change thresholds and health states.
Ops Center enables you to monitor the following parameters on Sun hardware:
Hardware health status
Manage and monitor the power states of a system and power systems on and off
Power usage for ILOM based servers and chassis
Monitor hardware variables and connectivity, including M-series servers
The Management Connector enables you to forward Ops Center OS and hardware monitoring notifications to Enterprise Manager, thereby enabling better correlation of IT problems across the technology stack.After the notifications are forwarded to Enterprise Manager, they are associated with the appropriate targets, depending on the mapping option(s) that you selected. The connector tracks the alerts forwarded from Ops Center and automatically updates information in Enterprise Manager. The alerts are cleared from the Oracle Enterprise Manager Grid Control seven (7) days after the alert is sent.The Ops Center notification severity appear as the following Alert severity in Enterprise Manager:
| Ops Center Notification Severity | Enterprise Manager Alert Severity |
|---|---|
| Low | Warning |
| Medium | Warning |
| High | Critical |
You can specify how alerts are triggered, and which alerts are triggered by configuring the monitoring parameters and the user's Notifications Profile in Ops Center.
The date and time for an Ops Center generated alert that appears in the Grid Control console might differ from the those that are generated by Enterprise Manager. In most cases, the timestamp reflects the date and time that Grid Control received the alert from Ops Center.
If an Ops Center Notification was sent to Grid Control, the timestamp displayed in each field is defined as follows:
Table 2-1 Alert Timestamp Definitions
| Field Name | Description of the Date and Time |
|---|---|
|
Message |
The date and time that the alert was triggered in Ops Center |
|
Alert Triggered |
The date and time that Grid Control received the alert from Ops Center |
|
Last Checked |
The date and time that Grid Control received the alert from Ops Center |
|
Last Collected Timestamp |
The date and time that Grid Control received the alert from Ops Center |
Note:
The actual date and time that the alert was identified by Ops Center appears in the alarm text.
