Table D–2 Kernel Reader Complex Rules

Rule ID 

Description 

Type of Alarm  

rknrd100

This rule covers a transitory event. The rule generates an alert alarm when the disk is over 75% busy, the average queue length is over 10, and the wait queue is increasing. The alert alarm remains until the disk is less than 70% busy and the average queue length is less than 8.

Alert 

rknrd102

This rule covers a transitory event. The rule generates an alert alarm if 90% of swap space is in use. The event causing the alarm remains until swap space in use is less than 80% of the total swap space.

Alert 

rknrd103

This rule covers a transitory event. The rule generates an alert alarm if swapping and paging is high for a given CPU. This behavior indicates that a CPU might be thrashing. An alert alarm is generated when CPU exceeds 1 swap-out, 10 page-ins, and 10 page-outs per second. The alert alarm stays on if CPU exceeds 1 swap-out, 8 page-ins, and 8 page-outs per second.

Alert 

rknrd105

File System Full error. This rule looks for a file system full error message in the syslog (/var/adm/message).

Alert alarm that is closed immediately 

rknrd106

No swap space error. This rule looks for a no swap space error message in the syslog (/var/adm/message).

Alert alarm that is closed immediately 

rknrd400

This rule checks for a continuous CPU load over six per CPU for four hours. 

Informational 

rknrd401

This rule checks for disks that are busy more than 90% of the file for x hours. The parameters field holds the last time CPU load was below six, and is initialized to some date in the year 2001.

Informational 

rknrd402

This rule checks if available swap space drops below 10% for x hours. The parameters field indicates the last time that the CPU load was below six. This field is initialized to some date in the year 2001.

Informational  

rknrd403 

This rule is not currently supported. 

Informational 

rknrd404

An informational alarm is generated if rule rknrd401 gets triggered 4 times. 

Informational 

rknrd405

An informational alarm is generated if rule rknrd402 gets triggered 4 times.
