- severity = warning
Annotations:
- message = System memory usage of 1.091G on os-wrk-0 exceeds 90% of the reservation. Reserved memory ensures system processes can function even when the node is fully allocated and protects against workload out of memory events impacting the proper functioning of the node. The reservation may be increased (https://docs.openshift.com/container-platform/latest/nodes/nodes/nodes-nodes-managing.html) when running nodes with high numbers of pods.

TODO: add graph url from annotations.
