Check target health statuses

If you don't have the Yandex.Cloud command line interface yet, install it.

The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name or --folder-id parameter.

1. See the description of the CLI's get attached resource status command:

   $ yc load-balancer network-load-balancer target-states --help
   

2. Get a list of all network load balancers:

   $ yc load-balancer network-load-balancer list
   +----------------------+--------------------+-------------+----------+----------------+------------------------+----------+
   |          ID          |        NAME        |  REGION ID  |   TYPE   | LISTENER COUNT | ATTACHED TARGET GROUPS |  STATUS  |
   +----------------------+--------------------+-------------+----------+----------------+------------------------+----------+
   ...
   | b7r97ah2jn5rmo6k1dsk | test-load-balancer | ru-central1 | EXTERNAL |              1 | b7roi767je4c574iivrk   |  ACTIVE  |
   ...
   +----------------------+--------------------+-------------+----------+----------------+------------------------+----------+
   

3. Choose the ID of the load balancer and the target group that is attached to it.

4. Request the status of the target group resources:

   $ yc load-balancer network-load-balancer target-states b7r97ah2jn5rmo6k1dsk --target-group-id b7roi767je4c574iivrk
   +----------------------+-----------+-----------+
   |      SUBNET ID       |  ADDRESS  |  STATUS   |
   +----------------------+-----------+-----------+
   | e9bc0iisdf7b00b7d4v0 | 10.10.0.4 | UNHEALTHY |
