List of Load Balancing Mode values for iControl Rest API Call

You can find the list of load-balancing methods from tmsh help. Run the command below from your console:

# tmsh help ltm pool

The command yields

load-balancing-mode [
          dynamic-ratio-member | dynamic-ratio-node |
          fastest-app-response | fastest-node |
          least-connections-members |
          least-connections-node |
          least-sessions |
          observed-member | observed-node |
          predictive-member | predictive-node |
          ratio-least-connections-member |
          ratio-least-connections-node |
          ratio-member | ratio-node | ratio-session |
          round-robin | weighted-least-connections-member |
          weighted-least-connections-node]

You can get the same information from the Configuration Utility (GUI) too: Just click the Help tab.

You can do the same with iControl REST, however, there is no direct iControl REST API for tmsh help, unfortunately. So, you need to call /mgmt/tm/util/bash to call tmsh to get a desired help (I know, it's awkward).

# curl -sku admin:<pass> https://<mgmtIP>/mgmt/tm/util/bash \
  -X POST \
  -H "Content-Type: application/json" \
  -d '{"command":"run", "utilCmdArgs":"-c \"tmsh help ltm pool\""}'

You may want to pipe the output to the following python one-liner for readability:

| python -c 'import sys,json; o=json.load(sys.stdin); print o["commandResult"]'

I hope this helps.
