Templates

The following examples are provided:

TemplateDescription
Four golden signalsSafeguard your service with the four golden signals: latency, traffic, errors, and saturation. This minimum set of objectives focuses on what matters regarding service reliability and performance.
Kubernetes workload saturationSafeguard your Kubernetes environment with dedicated resource utilization objectives for a Kubernetes workload (i.e., K8s deployment). The objectives focus on memory and CPU consumption of the workload.
Kubernetes cluster saturationConstantly check the resource consumption of your Kubernetes environment by validating CPU and memory objectives of a Kubernetes cluster.
Kubernetes namespace saturationSafeguard your Kubernetes environment with dedicated resource utilization objectives for a Kubernetes namespace. The objectives focus on memory and CPU consumption of the namespace including a reliability objective on the container restarts.
Host utilization and saturationProtect your infrastructure with resource consumption and saturation objectives for a dedicated host.
Security gateEstablish a security gate in your release process to ensure your releases have no known and exploitable vulnerabilities.

Entity selection for an objective

You can select which entities to use for an objective. When selecting an entity, it is prefilled with the correct DQL queries for the objective. The prefilled DQL query helps to configure the objective properly for that particular entity.

Template entity selection enables you

  • To select the right service/entity to guard.
  • To define the proper objectives for that particular service/entity.

It is also possible not to select entities. The DQL objectives need to be adjusted afterward, as they will just filter for something similar to HOST-PLACEHOLDER.
