[CLOSED] Feature request: Updating ratio for a node (pool-member)

[RavinderReddyF5]

Issue by mayurikini Wednesday Oct 09, 2019 at 17:51 GMT Originally opened as https://github.com/terraform-providers/terraform-provider-bigip/issues/163

---

I have a pool with load_balancing_mode as ratio-member. I am able to set this via terraform. I have 2 nodes as pool members, and I want 1 node to have 99% of the traffic and the other to have 1%. I don't see an option to set ratio for a node. I would like to have ratio as an option.

I do see dynamic_ratio, but I am not sure if dynamic_ratio and ratio in big_ip are same. If I update the dynamic_ratio of the nodes, I am not able to see that change in bigip. I don't see a field called dynamic ratio in bigip.

Let me know id I need to provide any more info. Versions: Terraform v0.12.7 + provider.bigip v0.12.4 P.S I am new to terraform and big_ip concepts, I am following docs in https://www.terraform.io/docs/providers/bigip/, so correct me if I am wrong. :)

@mayurikini please find below document for overview on ratio based load balancing method: https://support.f5.com/csp/article/K01052782

and also noticed we didnot have attribute for ratio setting on nodes in our resource files. creating internal JIRA Ticket to fix this issue[TER-123]

@RavinderReddyF5 Do we have an estimated date for getting ratio setting on nodes?

@RavinderReddyF5 I updated the ratio value for a node and while applying I could see the following in commandline:

Terraform will perform the following actions:
   bigip_ltm_node.node[1] will be created
  + resource "bigip_ltm_node" "node" {
      + address          = "********"
      + connection_limit = 0
      + dynamic_ratio    = (known after apply)
      + id               = (known after apply)
      + monitor          = "default"
      + name             = "/Common/XYZ"
      + rate_limit       = "disabled"
      + ratio            = 11
    }

In bigip, I did see the update for the node's ratio, but I don't see this update in pool > member ( My pool's load_balancing_mode is "ratio-node"). Here the ratio value is still 1. Is this expected?

@mayurikini we also noticed similar behaviour while adding ratio manually, this is nothing to do with terraform resource module, we are checking this behaviour with bigip team. can you please confirm this is reflecting by running some traffic test scenario.

@RavinderReddyF5 I did some load testing and looks like it is working as expected. I had kept ratio to be 9:1 for the pool members. First row is the pool, second and third row are the pool members.
