• SHOW TAG VALUES EXACT CARDINALITY WITH KEY = "index";
• SHOW SERIES CARDINALITY group by "measurement"; → Important useful one.
• influxdata/influxdb#8636 → Good examples are here
• influx_inspect report -detailed /var/lib/influxdb/data/envoy/autogen/903 The best way to ficure out high cardinality series.
• figure out series in each database use _internal ; select * from "database" where time > now() - 900s limit 10; Faced this error ERR: cannot delete data. DB contains shards using both inmem and tsi1 indexes. Please convert all shards to use the same index type to delete data.

• Setup untagged VLAN network also works
• https://www.belgai.de/blog/harvester/harvester_bridge_network/ add cloud init network data made it to work
• Loadbalancer creation were failing. Goto settings in harvester and set vip pools.
• If you add one more extra nic using the untagged network then creating an service object will lead to issue. The best is use the default managment network and create and service object to get an ip in the Subnet.
• to ssh into vm using clusterIP we can do kubectl port-forward and ssh
• Goto preferences and enable all the 4 settings including longhorn and rancher UI.
• We can use Nodeport and forward traffic to host ip and nodeport in Route Virtual servers.
• When we are port forwarding in router to ingress make sure ingress is configured with static NodePort. so that recreation ingress will always leads to fixed port.
• nginx ingress with letsencrypt. https://cloud.yandex.com/en/docs/managed-kubernetes/tutorials/ingress-cert-manager
