Parameters for Cloud Services Metrics

You can specify thresholds and optional alerts for Cloud Services metrics.

Thresholds

A threshold defines when a metric will receive a certain rating, such as Info (blue), Ok (green), Warning (yellow), Critical (red), or Fatal (red). If no threshold is defined for a metric, Health Monitoring uses the rating for the metric reported by the cloud service.

The types of threshold available depend on the type of metric:

Metric type: Status
- Available thresholds: Info Only, Status
Metric type: Performance
- Available thresholds: Info Only, Status, Numeric, Numeric (Critical)
Metric type: Quota
- Available thresholds: Info Only, Status, Numeric, Numeric (Critical)

The following threshold types are available:

Info Only: When you assign a threshold of the type Info Only to a metric, the rating of the metric that is reported by the cloud service is overwritten by the rating Info Only.
Status: When you assign a threshold of the type Status to a metric, the rating of the metric that is reported by the cloud service can be overwritten by a specified rating. For example, if the cloud service reports a Warning rating, you can specify in the threshold that the reported rating is overwritten by Critical.
You can also switch on Use delay and specify a delay in minutes before the rating of the metric is set to Critical. This means the rating of the metric is not set to Critical as soon as the threshold is reached, but only after the specified delay.
Numeric: When you assign a threshold of the type Numeric to a metric, you specify a limit at or above which the rating of the metric is set to Warning and a second limit at or above which the rating of the metric is set to Critical. For each limit, you must also specify the condition for setting the rating – for example, if the value of the metric is below or above the limit. Additionally, you can switch on Use delay and specify a delay in minutes before setting the rating of the metric to Critical. This means the rating of the metric is not set to Critical as soon as the limit is reached, but only after the specified delay.
When you specify a limit for a metric of the type Performance, you have to use the metric value when defining a limit.

Example of a Performance metric
The rating of the metric HDBCPU is set to Warning when the value of the metric is above 50%. The rating of the metric HDBCPU is set to Critical when the value of the metric is above 80%.

Example of a metric of the type Quota
The rating of the metric HDBMemoryConsumption is set to Warning when the usage is above 50%. The rating of the metric HDBMemoryConsumption is set to Critical when the usage is above 90%.

Numeric (Critical)
This threshold type offers similar functionality to the threshold of the type Numeric, with one exception: You can specify only one limit at or above which the rating of the metric is to be set to Critical.

Alerts (optional)

When you don't maintain a threshold, an alert is generated when the cloud service reports a metric status red (critical or fatal). When you maintain a threshold for a metric, an alert is generated when the defined threshold is reached. Alerts are displayed in the Health Monitoring and Alert Management applications.

The following Alert settings are available:

Alert Active
Set the switch to On to generate an alert when the metric rating is set to red. Set to Off to prevent alerts being generated.
Alert Name
Specify a name for your alert. Be sure to use a descriptive name that others can easily understand.
Notification Variant
Select an alert consumer variant of the type Notification to be informed when the metric turns red (for example, by e‑mail).
Outbound Variant
Select an alert consumer variant of the type Outbound Integration to create a support ticket in a ticketing system, for example.
Alert Category
Choose a category to categorize an alert so that you can display alerts by category in the Alert Management app.
Severity
Select a severity value from 0 (Very Low) to 9 (Critical).
Separate by Label
Create an alert for metrics with the specified label.
Alert Documentation
Describe the alert and provide any additional information that the user may need.

Alert Rules
An alert rule selects metrics of the destination. Select metrics by either their name or their label.
Use the Include table to select metrics for which alerts are created.
Use the Exclude table to select metrics for which no alerts are created.
