I had deployed eck-1.3.0 and elasticsearch 7.9.0 in GKE with 2 data-ingest and 3 master pods. Below is the one when I do get pods:

```auto
kubectl -n <ns> get po

NAME READY STATUS RESTARTS AGE
elastic-operator-0 1/1 Running 0 36m
elasticsearch-config-es-data-ingest-0 1/1 Running 0 33m
elasticsearch-config-es-data-ingest-1 1/1 Running 0 33m
elasticsearch-config-es-master-0 1/1 Running 0 33m
elasticsearch-config-es-master-1 1/1 Running 0 33m
elasticsearch-config-es-master-2 1/1 Running 0 33m

```

Below is the response when I checked the elasticsearch nodes status

```auto

[root@elasticsearch-config-es-data-ingest-0 elasticsearch]# curl -u "es-admin:es-admin" -k -X GET "https://elasticsearch-config-es-http:9200/_nodes/stats?pretty"
{
  "_nodes" : {
    "total" : 5,
    "successful" : 5,
    "failed" : 0
  },
  "cluster_name" : "elasticsearch-config"

```

I forcibly down one of the elasticsearch node down, so that total nodes would be 5, active nodes should be 4 and failed nodes should be 1.

```auto
 kubectl -n <ns> get po
NAME READY STATUS RESTARTS AGE
elastic-operator-0 1/1 Running 0 58m
elasticsearch-config-es-data-ingest-0 1/1 Running 0 55m
elasticsearch-config-es-data-ingest-1 0/1 ErrImagePull 0 55m
elasticsearch-config-es-master-0 1/1 Running 0 55m
elasticsearch-config-es-master-1 1/1 Running 0 55m
elasticsearch-config-es-master-2 1/1 Running 0 55m

```

But I can see the status as below inside the pod:

```auto
curl -u "un:pwd" -k -X GET "https://elasticsearch-config-es-http:9200/_nodes/stats?pretty"
{
  "_nodes" : {
    "total" : 4,
    "successful" : 4,
    "failed" : 0
  },
  "cluster_name" : "elasticsearch-config"

```

Is this the exact behaviour?

Yes, the API shows the number of active nodes. It doesn't track nodes that have left.

Thanks @warkolm . But in which case, `failed` must be updated in elasticsearch cluster.  
I mean for the below command:  
curl -u "un:pwd" -k -X GET "[https://elasticsearch-config-es-http:9200/\_nodes/stats?pretty](https://elasticsearch-config-es-http:9200/_nodes/stats?pretty)"

The `failed` field counts the number of nodes that were in the cluster but which failed to respond to this specific `_nodes/stats` request. It doesn't include any nodes that aren't in the cluster any more.

Okay. Is there any way to test that `failed` field count scenario.

What do you mean "test"? You should be able to trust Elasticsearch to get this right.
