This article details how logic triggers alerts, as well as how to view, filter and manage them.
What are Alerts?
Alerts are the result of the deployed Logic Modules. When a deployed Logic Module is TRUE for a period of time, that will generate an Alert.
Alerts are time periods of interest on connect equipment. They can represent faults, behaviour of interest, or simply a notification that a combination of variables meets some value. The meaning of an alert is entirely dictated by a User's Logic Modules.
Alerts are collected in the Alerts Analysis feature of the Platform.
There are two different Alerts Analysis views in the platform.
The first is a Portfolio level Alerts Analysis view, accessed through the Portfolio menu, and the second is a Site level Alerts Analysis view, accessed through the Site menu.
These views, while almost identical, are independent of each other, and saved views will not transfer between them. The main difference between them is that the Site version is pre-filtered to only show Alerts for that Site.
Which one should I use?
Both views perform the same function, so it's entirely up to you; we tend to use the Portfolio version for general investigation as all sites can be viewed simultaneously, and use the Site version to store filtered views we are interested in for each Site - but this doesn't need to be the same for you!

Views & Filtering
There are a few layouts available to the User when using Alerts Analysis - Stream, Grid, Time Series and Map. In each view, the Alerts can be filtered by site, date, category, name and severity.
The images below show the Time Series layout, with each of the view setting menus and the layout selector, found on the left hand side of the Alerts Analysis window.
Managing Alerts (in the Time Series view)
In the Time Series view, the alerts are 'rolled up' into a summary row for each Logic Module. These rows can be expanded to show the alerts generated for each individual Tag that the Logic Module has been shared to.
Expanded AHU Supply Pressure Alert
Every alert on the Switch Platform contains trend data from the data points that comprise their parent Logic Module. By clicking on an individual Tag within an expanded alert row, a User can see the actual data that triggered that Alert.

Filtering Using the Search Bar
The Search Bar is another useful tool that allows the user to filter down alerts based on any criteria of their choosing.
If a user wished to see all alerts for a particular tag, they could simply type it in the search bar.
For example, searching the tag 'AHU-HR-HC1-SAT' filters alerts by this tag.
As the user types, available search options are automatically suggested by the Platform.
