Requirements
SUSE Observability Self-hosted
Overview
Requirements for SUSE Observability client (browser) can be found at the bottom of the page.
Kubernetes and OpenShift
Supported versions
SUSE Observability can be installed on a Kubernetes or OpenShift cluster using the Helm charts provided by SUSE Observability. These Helm charts require Helm v3.x to install and are supported on:
Kubernetes: 1.21 to 1.30
OpenShift: 4.9 to 4.14
Resource requirements
There are different installation options available for SUSE Observability. It is possible to install SUSE Observability either in a High-Availability (HA) or single instance (non-HA) setup. The non-HA setup is recommended for testing purposes only. For production environments, it is recommended to install SUSE Observability in a HA setup. For a standard, production, deployment, the SUSE Observability Helm chart will deploy many services in a redundant setup with 3 instances of each service.
In the table below you can find the resource requirements for the different installation options. For the HA setup you can find different installation profiles depending on the size of the environment being observed.

The requirement shown for profile represent the total amount of resources needed to run the Suse Observability server. To ensure that all different services of Suse Observability server can be allocated:
For non-HA installations the recommended node size is 4VCPU, 8GB
For HA installations the min recommended node size is 8VCPU, 16GB
These are just the upper and lower bounds of the resources that can be consumed by SUSE Observability in the different installation options. The actual resource usage will depend on the features used, configured resource limits and dynamic usage patterns, such as Deployment or DaemonSet scaling. For our Self-hosted customers, we recommend to start with the default requirements and monitor the resource usage of the SUSE Observability components.
The minimum requirements do not include spare CPU/Memory capacity to ensure smooth application rolling updates.
For installation of SUSE Observability please follow the installation instructions provided below:
Storage
SUSE Observability uses persistent volume claims for the services that need to store data. The default storage class for the cluster will be used for all services unless this is overridden by values specified on the command line or in a values.yaml file. All services come with a pre-configured volume size that should be good to get you started, but can be customized later using variables as required.
For our different installation profiles, the following are the defaulted storage requirements:
Retention (days)

The storage estimates presented take into account a default of 14 days of retention for NONHA and 1 month for HA installations. For short lived test instances the storage sizes can be further reduced.
For more details on the defaults used, see the page Configure storage.
Ingress
By default, the SUSE Observability Helm chart will deploy a router pod and service. This service's port 8080 is the only entry point that needs to be exposed via Ingress. You can access SUSE Observability without configuring Ingress by forwarding this port:
When configuring Ingress, make sure to allow for large request body sizes (50MB) that may be sent occasionally by data sources like the SUSE Observability Agent or the AWS integration.
For more details on configuring Ingress, have a look at the page Configure Ingress docs.
Namespace resource limits
It isn't recommended to set a ResourceQuota as this can interfere with resource requests. The resources required by SUSE Observability will vary according to the features used, configured resource limits and dynamic usage patterns, such as Deployment or DaemonSet scaling.
If it's necessary to set a ResourceQuota for your implementation, the namespace resource limit should be set to match the node sizing requirements.
Client (browser)
To use the SUSE Observability GUI, you must use one of the following web browsers:
Chrome
Firefox
