Template

Description

Four golden signals

Safeguard 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 saturation

Safeguard 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 saturation

Constantly check the resource consumption of your Kubernetes environment by validating CPU and memory objectives of a Kubernetes cluster.

Kubernetes namespace saturation

Safeguard 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 saturation

Protect your infrastructure with resource consumption and saturation objectives for a dedicated host.

Security gate

Establish 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.
