Creating Threshold Profile

Thresholds let you define the status of an attribute based on specific conditions. A threshold is a predefined set of values associated to an attribute, based on which an Alarm can be generated. For example, you can define a threshold to show the status of the webserver as critical, if the response time exceeds 100 seconds. Likewise, you can define a threshold to show the status as clear, if the MBean's attribute - Active is equal to true.

To define a threshold, follow the steps given below:

1. Click New Threshold. This opens the Create New Threshold Profile screen.
2. You can create new Threshold Profiles for Numeric, String or Float values. Select the value type from the New Threshold Profile drop-down menu.
3. Select the Threshold Profile Type : Standard or Adaptive.
4. Threshold Profile Type — You can select if you are creating a profile for Standard or Adaptive Thresholds:
   • Standard Thresholds - You can set the profile for Critical, Warning or Clear severity with two conditions supported for every severity.
   • Adaptive Thresholds - Adaptive threshold has two categories - 'Automatic' and 'Manual':
     • Automatic: You can set the deviation percentage for the alert raised.

     • Manual:This can be categorized as:

       • Baseline: You can set a fixed Baseline Date Range from the drop-down menu. Check the checkbox to specify Baseline as %. If the box is unchecked, you can enter hard-coded values instead of the percentage.
       • Custom expression: Users can define their own expression from the available system options provided by the Applications Manager. Here are the Available System Variables:

       Use this option for Expressions	Description
       $10D_MVA	Ten Days Moving Average
       $30D_MVA	Thirty Days Moving Average
       $6H_MVA	Six Hours Moving Average
       $7D_MVA	Seven Days Moving Average
       $LastHourValue	Last Hour Average
       $10H_MVA	Ten Hours Moving Average

5. Specify the Threshold Name.
6. Configure the threshold for Critical, Warning or Clear severity. You can configure the threshold for Warning and Clear severity by enabling the Show Advanced Options checkbox.

7. Now specify the conditions for the Critical, Warning or Clear severity. We provide two condition support for every severity when creating Threshold Profiles. You can set the monitored value of a particular severity to be > (greater than), < (lesser than), = (equal to), != (not equal to), <= (lesser than or equal to), >= (greater than or equal to) to a customizable Threshold Limit. You can set additional condition when defining your threshold limit for each severity by clicking on the More link at the right-hand corner of the Create New Threshold Profile table.

   Note:

   • When creating a threshold for multiple strings, separate the values with commas. Ensure there are no spaces between a comma and a value.
   • While configuring threshold condition for all the severities, ensure that all values within the threshold's start and end points are considered. The threshold should be set in a way that the specified values are mapped and unique based on the conditions used for all the severities.
   • For example, if the value collected for the response time attribute of a Windows server monitor is 100 and the thresholds condition configured for that attribute is Critical > 50, Warning = 50, Clear < 50, then the condition matches for the Critical severity alone, whereas, it does not satisfy the conditions for Warning and Clear severities. As a result, only Critical alarm is generated for that attribute.
8. You can also specify a message that has to be appended to the alarm. By default, you can configure Critical severity, By clicking on advanced, you can configure Warning and Clear severity.

9. Specify the number of polls that can be scheduled before reporting an error. If you do not want to generate an alarm for the very first time the threshold condition is crossed, you can set Applications Manager to examine a certain X number of polls from a Y number of consecutive polls (both numbers are customizable), before generating an alarm. For e.g., If you want an email alarm to be generated only if the CPU Disk utilization is above 100%, consecutively for more than three polls out of five polls, then you can configure the number of polls to be examined out of a number consecutive polls before generating an alarm. By default, it takes the value from Global Settings. Refer Configuring Consecutive Polls for setting configurations for individual monitors.

   Note: In the case of Automatic Adaptive profiles:

   • Alarms will only get raised when the same severity occurs consecutively.
   • Globally configured settings will not be applied.
10. If you wish to apply the threshold only during specific time periods in a day/week, enable the Apply Threshold based on Business Hours option and select the Business Hour during which the threshold has to be applied.
11. In the Advanced Configuration section, specify the values for the following options:
    • Suppress Limit: If the monitored value falls below the configured limit, the alert is automatically marked as CLEAR. This setting bypasses all adaptive or baseline threshold checks and helps avoid alerts for very small or insignificant values.
    • Static Threshold: If the monitored value exceeds the configured static threshold limit, the alert is immediately marked as CRITICAL. This setting ignores adaptive threshold behavior and ensures that sudden or critical spikes are detected without delay for safety purposes.
12. Click Create Threshold Profile to add the threshold after defining all the conditions.
13. Choose the View Threshold option available on the top menu to view the threshold. The Threshold Profile screen lists all the default thresholds and newly created thresholds. Note: You can also edit the threshold created using the edit ( ) icon.

The thresholds thus defined can be associated with the attributes for determining the status of the attributes of the Monitor Group. You can also associate thresholds and actions directly through Global Alarm Configuration instead of the individual Monitor screen.

Refer to Associating Threshold and Action with Attributes for more details. 

Threshold & Action Profile CSV

Applications Manager gives you the ability to create a Threshold & Action profile report in .csv format. This report shows the threshold creation time, Monitor Group, Type, Threshold Profile, Threshold Status, Critical, Warning, and Clear Actions and more for catagorized and uncatagorized monitors. Here's how you can create the report:

• Click on View Threshold Profiles under the Threshold Profiles tab.
• Click the Threshold & Action Profile CSV button at the right- corner of the Threshold Details page.
• Select the checkbox for the kind of thresholds you want to create a report for. You can create a report for all thresholds, particular groups or disassociated monitors alone.
• Click Create CSV.
• A notification appears at the top of the page informing you that the "Threshold & Action profile report was successfully created. Download"
• Click Download to download the CSV file.

The downloaded CSV report contains the following columns:

Threshold Profiles in the Enterprise Edition

You can create Threshold Profiles from the Central Server in Applications Manager, the same as in the Professional Edition, and the profiles created automatically sync with the Probe Servers. However, these profiles can only be used and cannot be edited from the Probe Servers.
