ELK Stack on k8s instal

Hello everyone,
I would like to install ELK stack (Elasticsearch - Logstash - Kibana) with FileBeat and MetricBeat on an existing openedx on Kubernetes installed via Tutor.
I’m thinking about putting another Elastricsearch pod and not using the openedx’s one to avoid any conflict, would that be correct ?
Also, is it OK to install it on the same namespace as openedx?

Thanks !
