You can specify thresholds and optional alerts for Cloud Services metrics.
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:
The following threshold types are available:
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%.
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.
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:
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.
