logDNA supertenant agent volume mounts

Question

To accommodate multiple individual services in a single OpenShift cluster, I need to deploy multiple logDNA supertenant agents for each service in its own namespace.

These individual agents would then scrape logs from sub-directories under /var/log for example: agent-1 scrapes logs from /var/log/my-service-1, similarly agent-2 scrapes logs from /var/log/my-service-2.

However, while configuring these agents I also need to maintain isolation between each of them due to compliance requirements. This means I do not want these agents to unnecessarily share volumes, which I came across here while defining the agent yaml.

Please advise on why we need the below mentioned volumes and which I could drop from my configuration.

        - name: varlog
          hostPath:
            path: /var/log
        - name: vardata
          hostPath:
            path: /var/data
        - name: varliblogdna
          hostPath:
            path: /var/lib/logdna
        - name: varlibdockercontainers
          hostPath:
            path: /var/lib/docker/containers
        - name: mnt
          hostPath:
            path: /mnt
        - name: osrelease
          hostPath:
            path: /etc/os-release
        - name: logdnahostname
          hostPath:
            path: /etc/hostname

I understand for configuring lookback in the agent I need the /var/lib/logdna volume but not particularly sure on the other volumes. I specifically feel like I could drop the /var/data and /var/lib/docker/containers as these shared directories between the deployed cluster services and need not be mounted for compliance sake.
