Yes,
Now in the above case both Replicaset and Deployment replica count are the
same.
If the count is different its like below
input_series:
- series: kube_replicaset_spec_replicas{job="prometheus",
namespace="auth-proxy"}
values: '5+0x9 *5*+0x20'
- series:
kube_deployment_status_replicas_available{job="prometheus",
namespace="auth-proxy"}
values: '5+0x9 *4*+0x20'
It will generate an alert.
But if the count is the same, I still get an error.
