There are 3 different ways you can create alert / event filters:

  1. manually create an event filter (gear icon -> event filters)
  2. when you look at a specific event under "Events", you can select "Filter similar events". A filter will then be created and can be viewed under "Event filters"
  3. from Topology, at any section you can select "Mute". This will create a filter for the component you are currently viewing. You can edit or delete the filter under "Event filters"

Below is a video going through the three different options.
