How do I edit threshold values for Web Application Monitoring?

Introduction

To edit threshold values

To edit the response size limit threshold

To remove/revert threshold overrides

Introduction:

In Entuity, there are two thresholds for SSL certificate expiry - Warning and Critical.

By default, these are set the following values:

• Warning - between 60 and 31 days until SSL certificate expiry.
• Critical - 30 days or fewer until SSL certificate expiry or the HTTP Response Code returned is 400 or higher.

These can be edited via the Thresholds dashboard.

Web Application Performance Polling has a default response size limit set to 1 megabyte (1000000 bytes) which refers to the maximum number of bytes to read from the response. If there is additional data after the limit, the rest of the data will be discarded.

This limit can be edited via the entuity.cfg file.

To edit threshold values:

You can edit the threshold values of one or more web apps at the same time via the Thresholds dashboard. To access this:

1. Navigate to the Web Application Management page.
2. Select the web app(s) for which you wish to edit the threshold values.
3. Right-click to open the Context Menu, and click Threshold Settings.
   
   
   
   
4. This will open the Thresholds dashboard for the selected web app(s). Note, if multiple web apps are selected, the Threshold dashboard will be a standalone dashboard, and there will not be other dashboards available for the grouped web apps.
5. Select the threshold you wish to edit and click Set Override at the top of the page (or via the right-click Context Menu).
   
   
   
   
6. The Set Override form will open on the right of the window. Specify the new value (in days) for the selected threshold and ensure that it is Enabled.  Click Done in the top right to save your changes, otherwise click Cancel.
   
   
7. Once saved, the Thresholds table will be updated with the new value.

To edit the response size limit threshold:

You can edit the response size limit max value via the entuity.cfg file. For additional information, please refer to the entuity.cfg article or reach out to the Entuity Support team if you have any questions.

1. Navigate to the [Entuity Home]/etc directory and open the entuity.cfg file.
2. Add the following section to the file with the new limit as bytes. The example below sets the limit to 2 MB (2000000 bytes).
   
   • Note, this must be a positive number, if a negative number is set polling will not complete successfully.

   • [WebApp]
     responseSizeLimit=2000000

3. Once this has been entered, save the file.
4. Follow the configuration procedure based on your operating system from the [Entuity Home]\install directory:
   • On Linux, enter:

     • ./configure [defaults]

   • On Windows, enter:

     • configure [text | defaults]

To remove/revert threshold overrides:

You can revert edited thresholds to their original value from the Thresholds dashboard, by selecting the desired threshold and clicking Remove Override from the right-click Context Menu.
