if an cx wants to collect it, they can enable through using configmap
by changing
exclude_namespaces = ["kube-system","gatekeeper-system","azuresecuritylinuxagent"]
to
exclude_namespaces = ["kube-system","gatekeeper-system"]

exclude_namespaces = ["kube-system","gatekeeper-system","azuresecuritylinuxagent"]
# If you want to collect logs from only selective pods inside system namespaces add them to the following setting. Provide namepace:controllerName of the system pod. NOTE: this setting is only for pods in system namespaces
