OpenSearch PerfTop metric values are not showing properly in k8s

[GaneshbabuRamamoorthy]

Hi All,

I tried deploying OpenSearch helm chart in my k8s cluster and below is the pod status,

[root@k8master1 robin]# kubectl get pods -n es
NAME                             READY   STATUS    RESTARTS   AGE
opensearch-cluster-master-0      1/1     Running   4          21d
opensearch-cluster-master-1      1/1     Running   4          21d
opensearch-cluster-master-2      1/1     Running   0          21d

and I tried executing the below commands inside the pod to enable performance analyzer

curl -XPOST https://opensearch-cluster-master:9200/_plugins/_performanceanalyzer/cluster/config -H 'Content-Type: application/json' -d '{"enabled": true}' -u 'admin:admin' -k
curl -XPOST https://opensearch-cluster-master:9200/_plugins/_performanceanalyzer/rca/cluster/config -H 'Content-Type: application/json' -d '{"enabled": true}' -u 'admin:admin' -k

curl -k -u admin:admin -XPOST https://opensearch-cluster-master:9200/_plugins/_performanceanalyzer/batch/config -H 'Content-Type: application/json' -d '{"enabled": true}'
curl -k -u admin:admin -XPOST https://opensearch-cluster-master:9200/_plugins/_performanceanalyzer/batch/cluster/config -H 'Content-Type: application/json' -d '{"enabled": true}'

[opensearch@opensearch-cluster-master-0 ~]$ curl -k -u admin:admin -XGET https://opensearch-cluster-master:9200/_plugins/_performanceanalyzer/config
{"performanceAnalyzerEnabled":true,"rcaEnabled":true,"loggingEnabled":false,"shardsPerCollection":0,"batchMetricsEnabled":true,"batchMetricsRetentionPeriodMinutes":7}

[opensearch@opensearch-cluster-master-0 ~]$ curl -k -u admin:admin -XGET https://opensearch-cluster-master:9200/_plugins/_performanceanalyzer/cluster/config
{"currentPerformanceAnalyzerClusterState":11,"shardsPerCollection":0,"batchMetricsRetentionPeriodMinutes":7}

and then I have tried downloading the opensearch perf top linux and copied the file to inside the pod,

https://github.com/opensearch-project/perftop/releases/download/1.0.0.0/opensearch-perf-top-1.0.0.0-linux-x64.zip

I executed the below command inside the pod to see the performance of cluster,

[opensearch@opensearch-cluster-master-0 opensearch-perf-top-linux]$ ./opensearch-perf-top-linux --dashboard ClusterOverview --endpoint localhost:9600

below is the response I got in the cmd line,

[opensearch@opensearch-cluster-master-0 opensearch-perf-top-linux]$ ./opensearch-perf-top-linux --dashboard NodeAnalysis --endpoint localhost:9600

below is the response I got in the cmd line,

[opensearch@opensearch-cluster-master-0 opensearch-perf-top-linux]$ ./opensearch-perf-top-linux --dashboard ClusterThreadAnalysis --endpoint localhost:9600

below is the response I got in the cmd line,

Can you please help me to understand why the special characters are showing in the dashboard.

Please correct me If I am doing anything wrong in the setup.

Attached the performance analyzer properties file for reference,
