OS Health States

Each operating system (OS) is monitored for the following characteristics:

• Connectivity
• File system status
• CPU usage
• Memory usage

You can set specific threshold values for different operating systems.

The OS health states are displayed as follows:

• Good - The server is working properly.
• Unknown - An error occurred while attempting to retrieve information about the health of the OS resource. The server is connected but does not return any information.
• Unreachable - The server agent IP address cannot be contacted for the status of the health of the OS resource. This status indicates network problems or that the server is in standby mode.
• Uninitialized - The server is not showing the status of OS resource health because the OS monitoring feature has not been added to the server.
• Warning Failure - A potential or impending fault condition has been detected on the server. Action should be taken to prevent the problem from becoming more serious.
• Critical Failure - A fault condition has occurred on the server. Corrective action is required.

Monitoring Thresholds

Some attribute threshold values are measured in terms of percentage. The valid range is 0 to 100%. If a value is entered outside this range, an error is generated. For attributes that do not measure percentages, the values depend on the number of processors in your system and on the usage characteristics of your installation.

The value of any given monitored OS health attribute is compared to a threshold value. Warning and critical threshold values can be configured. Attribute values are compared against the thresholds at regular intervals.

If the value of a monitored OS health attribute rises above the warning threshold, notification is issued with the status of Warning Failure. If the value continues to increase and passes the critical threshold, notification is issued with the status of Critical Failure.
