Configuring Threshold Profiles for Servers and Applications

Introduction

This section is common to all the editions of IT360 - Professional Edition, Enterprise Edition [Probes only] and MSP Edition [Probes only].

A threshold is a predefined set of values associated to an attribute, based on which an alarm is generated.
Example: You can create a threshold profile for the attribute- CPU Utilization and alarm will be generated if the CPU Utilization exceeds 70%.

Thresholds lets you define the status of an attribute, based on specific conditions. For example, you can define a threshold, to show the status of a web server as critical, if the response time exceeds 100 seconds. Similarly, you can define a threshold to show the status as clear, if the MBean's attribute - Active is equal to true.

Note:

1. An attribute is a parameter/property of a monitor which provides information about the monitor (Example: Response Time, CPU Utilization, Memory Utilization, etc.

2. "Polls to try": Leave this field empty, if you want the "Admin --> Alarms -> Action/Alarm Settings --> "Retry" settings to take effect. To reduce alarms due to a temporary surge in CPU Utilization, you may want to set the 'Polls to try' as two or a higher number. If you set it as two, then the alarm will be generated only if the CPU Utilization has crossed the threshold during two consecutive polls.

The following is the sequence in managing Threshold profiles:

  1. Adding a Threshold Profile

  2. Editing a Threshold Profile

  3. Associating Thresholds with Attributes

  4. Deleting a Threshold Profile

  5. Consecutive Polls

1. Steps to Add a Threshold Profile

To define a threshold, follow the steps given below. Refer the screenshots given, for better understanding;

  1. Login to IT360 console with the Username and Password of an Admin user.

  2. Click the Admin tab in the header pane.

  3. Click Threshold & Anomalies under Alarms.

  4. In the wizard displayed, by default, Servers & Applications will be chosen under the Action Profiles for dropdown. Also, you will see the List View of the existing threshold profiles. Click 'Add New'.
  1. In the 'Create New Threshold Profile' wizard displayed, do the following:

  2. Create New Threshold Profile for either Numeric Values, or String Values.

  3. Specify the Threshold Name.

  4. Specify the conditions for the different severity of the alarms. You can also specify a message that has to be appended to the alarm. By default, you can configure Critical severity.

  5. Select the Show Advanced Options checkbox to configure Warning severity and Clear severity.

  6. Click the Create Threshold Profile button, to add the threshold, after defining all the conditions.

Your threshold profile is successfully created. Now, you can associate the same to an attribute of a monitor instance using the 'Configure Alarms' link of the attribute, to receive Alarms.

2. Editing a Threshold Profile

  1. From the List View of the existing threshold profiles, click the icon beside the required threshold profile.

  2. Make the required changes and click Update Profile.

3. Associating Thresholds with Attributes

Once the thresholds are defined, the next step is to associate them with attributes, for determining the status of the attributes of a Business Service. Refer here for detailed steps.

4. Deleting a Threshold Profile

  1. From the List View of the existing threshold profiles, select the checkbox(es) beside the required threshold profile(s).

  2. Click the Delete link.

  3. Click OK in the confirmation window displayed.

    Note: Deleting a threshold profile will also delete its association with the attributes and alarms generated by it.

5. Consecutive Polls

Under the List View of the existing threshold profiles, you can see the Consecutive Polls section. Click the Configure link. It takes you to the Action / Alarm Settings wizard, where you can Configure the Consecutive Polls Count.
