PMM client restarts

I am testing the PMM on kubernetes cluster. I am running percona operator with percona-pxc, haproxy and pmm-server. When I enable pmm client in helm values it starts pmm-client side-cars in percona-pxc and haproxy pods. I am adding mysq services from pmm-client with pmm-admin add mysql. The problem is that in the event when pmm-client container restarts I have to run pmm-admin add mysql again. How can I keep the metrics going even if the pmm-client restarts?
