Set and configure a counter alert threshold

Set a counter alert threshold

To set an alert threshold on a counter, it is necessary to display the Counter Configuration wizard:

from the monitored machines tree, in the Alert Thresholds after selecting a counter, or
from the monitored machines tree, in the Alert Thresholds after clicking on the Configure Counters button and selecting a counter.

Enable alert triggering: Checking the check box causes alerts to be triggered when the alert thresholds defined for the selected counter are exceeded.

Add a new threshold: Clicking the button adds a new alert threshold to the selected counter.

Remove the selected threshold: Clicking the button deletes the selected alert threshold.

Move the selected threshold up: Clicking the button moves the selected alert threshold up the displayed list.

Move the selected threshold down: Clicking the button moves the selected alert threshold down the displayed list.

Restore the default setting of the selected threshold: Clicking the button restores the default alert thresholds for the selected counter.

Copy alert thresholds: Clicking the button makes a copy of the alert thresholds for the selected counter.

Paste alert thresholds: Clicking the button pastes the copied alert thresholds.

To set an alert threshold from the counter definition, follow these steps:

Select the required counter in the monitored machines tree.
In the right-hand panel, click on the Alert Thresholds tab. The wizard is displayed.

To set an alert threshold on a counter from the monitor definition, follow these steps:

Select the required Monitor in the monitored machines tree.
In the right-hand panel, click Configure Counters.
Select the required counter, and click on the Alert Thresholds tab in the right-hand panel. The wizard is displayed.

Configure a counter alert threshold

NeoLoad is able to set default alert thresholds. Counter alert thresholds can be also modified or added manually. Each alert threshold defines a condition under which an alert is triggered. When an alert threshold is exceeded during a test, an alert is generated. Alerts can be viewed in the Alerts tab both in the Runtime section and the Results section.

Thresholds definition

A threshold definition contains the following information:

Operand: the condition that triggers the alert.

The available conditions are: lesser or equal to, greater or equal to, equal to and between two values.
Value: the value that triggers the alert.
Delay: the triggering delay for the alert.

An alert is triggered when the corresponding condition is met for a period at least equaling the triggering delay. The triggering delay is set either for a given time or for a number of times the condition is met.
Severity: the alert severity level (critical or warning).

Only one alert threshold may be exceeded at one time for one given counter. By default, a critical alert is considered more important than a warning alert. If more than one alert threshold is exceeded simultaneously on a same counter, the alert threshold taken as having been exceeded will be the one that is highest placed in the list of thresholds.

The severity depends on the resources used for the selected counter. A critical-level alert denotes a critical problem with a given resource that can only be resolved through the user's intervention. A warning-level alert indicates that a resource is close to its operational limits.
Description: the alert description for the user's information purposes.

This description appears in the final report.
