Set up service level agreement
To set up the widget, go into edit mode by clicking on Edit in the top right corner.
Below the main area, enter a name for the widget and select a quota. You can manage the quotas by clicking on the Manage Quotas icon next to the Quotas dropdown (also see Quotas below).
- Pre-alarm when the projection exceeds quota
If you enable this option, you can select an alarm chain that should be triggered as soon as the calculated expected value will exceed the quota by the end of the year.
- Main alarm when the value exceeds quota
If you enable this option, you can select an alarm chain that should be triggered when the actual value exceeds the quota.
Quotas
A quota consists of a number of conditions that a given data point must satisfy over the course of a year. Each of these conditions can have a lower and an upper limit and a number of hours that the data point is allowed to remain between these limits per year.
Example
Assume the following rules should be monitored for the temperature of a computer room:
Condition |
Quota |
|---|---|
\(x < 2 °C\) |
none (i.e. raise alarm immediately) |
\(2 ≤ x < 12 °C\) |
max. 100 h/a |
\(12 ≤ x < 20 °C\) |
unlimited (target temperature) |
\(20 ≤ x < 28 °C\) |
max. 500 h/a |
\(28 ≤ x < 35 °C\) |
max. 50 h/a |
\(x ≥ 35 °C\) |
none (i.e. raise alarm immediately) |
Create a new quota for these rules, enter a name for it (e.g. “Computer Room”) and add the following conditions:
Minimum |
Maximum |
Quota [h] |
|---|---|---|
empty |
2 |
0 |
2 |
12 |
100 |
20 |
28 |
500 |
28 |
35 |
50 |
35 |
empty |
0 |
You don’t need to enter intervals that don’t have a time contraint.
Note
Quotas are saved on the client, meaning that all quotas are available in any Service Level Agreement widget anywhere in the same account. You can define as many quotas as you want, but only one quota can be active in any SLA widget. If you want to use multiple quotas, you’ll need to create a separate widget for each.
Locations
Locations are used to assign data points to the widget. A location can represent a physical place (e.g. a room or a plant) or any other part of your real estate you want to monitor.
To add a new location to the widget, click on Add Location above the Locations list.
For each location, you can configure the following settings:
- Label
Enter the name of the location, plant or room. This name will be displayed on the main view of the widget.
- Input
Drag a data point from the panel on the right onto this field. The prediction will be based on the values of this data points, both historic and current.
