Threshold and Availability for Web Page Speed (Browser)

Add Threshold and Availability for Web Page Speed (Browser)

1. Click Admin > Configuration Profiles > Threshold and Availability.
2. Click Add Threshold and Availability in Threshold and Availability screen.
3. Specify the following details for adding threshold and downtime rules for Web Page Speed (Browser):
   • Monitor Type: Select Web Page Speed (Browser) from the drop down list.
   • Display Name: Provide a label for identification purpose.
   • Number of locations to report monitor as down: Choose from the drop down to receive alert notification when the website is down from specified number of locations.
     
     
4. Threshold Type: Choose the threshold type of your preference.    

   4.1 Static Threshold:
   Static threshold can be selected if you wish to configure thresholds for individual attributes manually. If you're choosing the static threshold, specify the following details for configuring the threshold:

   • Alerts if any objects broken: Enable to option to alert if there are any broken objects such as images, CSS, Javascript etc found in the webpage while monitoring.
   • Notify when the website content changes by percentage: Enter a value in percentage to get notified when the content in your website is changed beyond the specified value.
   • Notify when image count crosses: Receive alerts when the total number of images in your website cross the set threshold value.
   • Notify when image size changes: Get notified when the image size varies from the set value in percentage.
   • Notify when image size exceeds: Alerts will be triggered if the total image size exceeds the set value in bytes.
   • Notify when script count crosses: Receive alerts when the total number of scripts in the webpage cross the set threshold value.
   • Notify when script size changes: Get notified when the total size of the scripts in the webpage varies from the set value.
   • Notify when script size exceeds: Alerts will be triggered if the size of the scripts exceeds the set threshold value.
   • Notify when CSS count crosses: Receive alerts when the total CSS count cross the set threshold value.
   • Notify when CSS size changes: Get notified when the CSS size varies from the set value in percentage.
   • Notify when CSS size exceeds: Alerts will be triggered if the CSS size exceeds the set value in bytes.
   • Notify when the size of an image exceeds: Alerts will be triggered when the size of individual images exceeds the set threshold value.
   • Notify when the size of a script exceeds: Alerts will be triggered when the size of an individual script exceeds the set value in bytes.
   • Notify when the size of a  CSS exceeds: Alerts will be triggered when the size of an individual CSS exceeds the set threshold value.
   • Response time threshold for primary monitoring location: Enter a value in milliseconds to get notified when the response time from primary location crosses the specified value.
   • Response time threshold for secondary locations: Enter a value in milliseconds to get notified when the response time from secondary location crosses the specified value.
     
     
     
     Advanced Threshold Settings (Strategy):
     Poll count serves as the default strategy to validate the threshold breach. You can validate threshold breach by applying multiple conditions (>, <, >=, <=, =) on your specified threshold strategy. The monitor’s status changes to ”Trouble or Critical”  when the condition applied to any of the below threshold strategies hold true:

     • Threshold condition validated during the poll count (number of polls): Monitor’s status changes to trouble or critical when the condition applied to the threshold value is continuously validated for the specified “Poll count”.
     • Average value during poll count (number of polls): Monitor’s status changes to trouble or critical, when the average of the attribute values, for the number of polls configured, continuously justifies the condition applied on the threshold value.
     • Condition validated during time duration (in minutes): When the specified condition applied on the threshold value is continuously validated, for all the polls, during the time duration configured, monitor’s status changes to trouble or critical.
     • Average value during time duration (in minutes): Monitor’s status changes to trouble or critical, when the average of the attribute values, for the time duration configured, continuously justifies the condition applied on the threshold value.

     
     Multiple poll check strategy will not be applied by default. During the conditions where no strategy could be applied, the threshold breach will be validated for a single poll alone.
     
     
     To make sure the condition applied on the strategy “Strategy-3: Time duration or Strategy-4: Average value during time duration” for threshold breach detection works as intended, you must ensure that you specify a time duration which is at least twice the applied check frequency for that monitor.
     4.2. AI-based threshold:
     The AI-based threshold will track the abnormal spikes using anomaly detection and will offer a dynamic threshold which will be updated accordingly. If you're choosing AI-based threshold, choose associated anomaly severityand the status accordingly.
     • Response time threshold for primary monitoring location: Choose the anomaly severity, associated severity status and IT automation to be applied and get notified in case if trouble or critical status, if the response time from the primary location has an anomaly.
     • Response time thresholds for secondary monitoring location: Choose the anomaly severity, associated severity status and IT automation to be applied and get notified in case if trouble or critical status, if the response time from the primary location has an anomaly.
