Error handling<br />

Check CPU Overload<br />

This nested error handling rule set handles measures that are taken when the CPU load exceeds a<br />

configured value.<br />

Nested error handling rule set — Check CPU Overload<br />

Criteria — Statistics.Counter.GetCurrent(“CPULoad”)<br />

greater than or equals 95<br />

The rule set criteria specifies that the rule set applies when the value of the Statistics.Counter.<br />

GetCurrent property for CPU load is 95 or higher. This value indicates the percentage of the maximum<br />

load that the CPU is currently running with.<br />

The Statistics module, which provides the value, runs with default settings, as is specified after the CPU<br />

Load property parameter.<br />

The rule set contains the following rules:<br />

Create notification message<br />

Always –> Continue — Set User-Defined.loadMessage =<br />

“CPU load at “<br />

+ Number.ToString (Statistics.Counter.GetCurrent(“CPULoad”))<br />

+ “%”<br />

The rule is always executed when the criteria of its rule set is matched. The rule then uses an<br />

event to set a user-defined property to a chain of values that make up a message text on the CPU<br />

overload.<br />

The Continue action lets processing continue with the next rule.<br />

Send SNMP trap and other rules<br />

Always –> Continue — ...<br />

The Send SNMP trap rule and other rules in the rule set are always executed when the rule set<br />

criteria is matched. The rules then use different events for taking measures to make the<br />

administrator aware of the CPU overload.<br />

Note: These rules are not enabled by default.<br />

Check Cache Partition<br />

This nested error handling rule set handles measures that are taken when the web cache usage<br />

exceeds a configured value.<br />

Nested error handling rule set — Check Cache Partition<br />

Criteria — Statistics.Counter.GetCurrent(“<strong>Web</strong>CacheDiskUsage”)<br />

greater than or equals 95<br />

The rule set criteria specifies that the rule set applies when the value of the Statistics.Counter.<br />

GetCurrent property for web cache usage is 95 or higher. This value indicates the percentage of the<br />

maximum allowed usage of the web cache that is currently in use.<br />

The Statistics module, which provides the value, runs with default settings, as is specified after the<br />

<strong>Web</strong>CacheDiskUsage property parameter.<br />
