A tool for monitor connectivity inside a ES cluster

Introduction

This exporter queries data from each ES nodes API. Then expose these data at /metrics. You need to put your full ES node list of every cluster need to be monitored inside targets folder for the expoter to queries data from.

Manual query to ES node

curl -s 10.0.0.10:9200/_cluster/stats | jq ._nodes

10.0.0.10:9200
{
  "total": 10,
  "successful": 7,
  "failed": 3,
}

Supported metrics

The exporter support 3 metrics at: {local_IP}:{listen_port}/metrics

• Successful connected node: elasticsearch_node_connectivity_successful{cluster,exported_instance}
• Disconnected node: elasticsearch_node_connectivity_failed{cluster,exported_instance}
• Total node of cluster: elasticsearch_node_connectivity_total{cluster,exported_instance}

How to use

Target file

Put your list of ES nodes inside "./targets" folder

Target file is in json format

Example: cluster1.json

{
    "cluster_name": "es_6_3",
    "node_list": [
        "{{IP_1}}:9200",
        "{{IP_2}}:9200",
        "{{IP_2}}:9200",
    ]
}

Build command

go run main.go -port 8080 -folder ./targets/ -log-file ./log.txt

Build it from source

env GOOS=linux GOARCH=amd64 go build -o ./bin/es_connectivity_exporter ./

# Run it
./es_connectivity_exporter -port 8080 -folder ./targets/ -log-file ./log.txt
