Set general threshold rule properties

NOTE:
The general rule properties tab is only valid for the Measurement Threshold Policy.

message

Threshold level description: This is a name you give to the rule to help you identify it. This name is visible in the rules list.

Threshold Limit: If you are setting a Minimum or Maximum rule, set the value that triggers a message if met or crossed.

Use the following syntax guidelines when specifying the threshold:

Sequence of Digits:

May include a decimal separator. (The character used as the separator is determined by the operating system language.)
For example: 0.5, 100.1

Sign (optional):

Plus sign (+). For example: +50

Minus sign (-). For example: -730

Exponent (optional):

Exponent character: e or E. For example: 15e2, 7E4

Exponent sign. For example: 8e+2, 4E-2

One or more decimal digits. For example: 25.88e4

TIP:
If you set a minimum or maximum threshold limit, you can override it for individual nodes if necessary. Click for details.

To override a threshold limit on an individual node, set a parameter locally on the node in the eaagt.thresholds namespace. Specify the parameter value in the following format:

<policy_name>/<threshold_level_description>/<limit>:<reset_value>

For example, if you have a policy called cpu load with a threshold level called condition critical that you want to override with the limit 75 and the reset value 70, set a parameter with the following value:

cpu load/condition critical/75:70

The following limitations apply:

Specify <policy_name> and <threshold_level_description> exactly as they appear in the policy editor. The first and last slash marks (/) delimit the <threshold_level_description>, which can itself contain slash marks.
<reset_value> is required, even if it is the same as <limit>.
Nodes must have the HTTPS agent installed.

Set the parameter using one of the following methods:

Deploy a node info policy that contains the following line:

<parameter_name>(thresholds) <parameter_value>

The <parameter_name> can be any alphanumeric string that is unique within the eaagt.thresholds namespace. Adding (thresholds) after <parameter_name> ensures that the node info policy sets the parameter in the eaagt.thresholds namespace. (See Node Info Policy Type.)
Use the command ovconfpar with the following syntax:

ovconfpar -change -host <node_hostname> -ns eaagt.thresholds -set <parameter_name> <parameter_value>

The <parameter_name> can be any alphanumeric string that is unique within the eaagt.thresholds namespace. (See ovconfpar.)

If you are setting a Visual Basic© Scripting Edition or Perl rule, you must write a script that evaluates the data you are monitoring and sets the Rule Object to either TRUE or FALSE. See Policy objects and examples for information about writing threshold scripts.

Short-term peaks Since it may not be reasonable to create a message when a threshold is exceeded only for a short time, HP Operations allows you to define a minimum time period over which the monitored value must exceed the threshold before generating a message. For a message to be sent, the value must be greater than the threshold each time the value is measured during a duration that you select. If the duration is set to 0 or the box is left empty, an alarm is generated as soon as HP Operations detects that the threshold has been equaled or crossed.

Reset The reset value is a limit below which the monitored value must drop (or exceed, for minimum thresholds) to return the status of the monitored object to normal. After the status of a monitored object returns to normal, a new start message can be issued if the monitored value again crosses the threshold value. You can either use the same value as the threshold limit, or specify a different reset value.

Set the Measurement Threshold general rule properties:

Right-click the policy and select All Tasks

Edit...

Select Threshold levels.

Select the rule to which you want to modify the conditions.

Select Modify.

Select General.
