Composite SLA

In this screen, you can define SLA rules for both availability and response time of your websites and servers.

To get started, click the New Composite SLA link under SLA->New SLA.

To configure a new composite SLA, you need to follow the steps explained below:

SLA Name:  Provide a name that uniquely identifies the SLA. This is a mandatory field.
Description: You can provide a brief description explaining the SLA in this field.
Business Hours: If you have defined any business hours previously, you can specify it here. The response time SLA will then be applicable for the timeframe defined within the Business Hour.

For example, assume you have defined a business hour named 'Friday' as between 08:00 to 20:00 hours. This timeframe is applicable every Friday. Now if you specify this business hour for the SLA, the SLA will be considered for a time period of 08:00 to 20:00 hours on Fridays.

SLA Period: Specify the time period for the SLA. You can select either monthly, quarterly or yearly SLA.
SLA Goal: To meet the SLA, availability can be set as equal to, greater than, greater than equal to, less than or less than or equal to a percentage value. By default, it is 99.0 %.

You can add multiple SLA goals if required by clicking the 'more' link adjacent to the 'SLA Goal' field. You may use color coding to differentiate between multiple SLA goals or targets. Click the colored icon next to the first text field in the SLA  Goal section. This will open the color picker tool with which you can select appropriate color for the goal.

Refer the screenshot below for a sample SLA Goal setting:

Define Service Level Objectives: In this section, you need to define the service level objectives (SLO) for your SLA, the availability and response time criteria and the total weightage to be applied for each criteria.

SLO represents the service level objectives for the SLA. The objectives have to be defined for availability and response time of the monitor.
Weightage represents the level of importance, expressed as a percentage value, for availability & response time.

The SLA Achieved value is calculated using the below formula:

Associate SLA to Monitors: In this step, you associate the monitors in your account to the SLA. You can select the monitors from the available list.
