    The Mistwatcher page appears.
  3. To add/update the mistwatcher, complete the input fields of the mistwatcher entry according to the following instructions.

    • Query Name: Enter the name of the mistwatcher entry. (Choose the name carefully, as it cannot be edited later.)
    • Active: If Active is enabled, your query is active to be executed. If not, it is inactive for execution.
    • Schedule: You can schedule how often this query needs to be executed (for example, @every 1h, @every5m...).

    • Profile: Choose the profile based on your query and requirement. Select the drop-down icon, which displays a list of available profiles.
    • Query String: Click on the Query String check box. This displays a text box prompting Enter Query String. Type your query here.
