# Elasticsearch Network Connectivity or Latency Issues.

This incident type refers to issues related to network connectivity or latency in Elasticsearch, which is an open source search and analytics engine. These issues can result in slow performance, timeouts, or even complete unavailability of the Elasticsearch service. The root cause of such incidents could be a variety of factors such as network congestion, hardware failure, configuration errors, or software bugs.

### Parameters

```shell
export ELASTICSEARCH_HOST="PLACEHOLDER"
export PORT="PLACEHOLDER"
export TIMEOUT_VALUE="PLACEHOLDER"
```

## Debug

### Check if Elasticsearch service is running

```shell
systemctl status elasticsearch
```

### Check Elasticsearch logs for errors

```shell
journalctl -u elasticsearch --since "10 minutes ago"
```

### Ping Elasticsearch host

```shell
ping ${ELASTICSEARCH_HOST}
```

### Check network connectivity to Elasticsearch host

```shell
nc -vz ${ELASTICSEARCH_HOST} ${PORT}
```

### Check Elasticsearch cluster health status

```shell
curl -X GET "http://${ELASTICSEARCH_HOST}:${PORT}/_cluster/health"
```

### Check Elasticsearch node status

```shell
curl -X GET "http://${ELASTICSEARCH_HOST}:${PORT}/_nodes/stats"
```

### Check Elasticsearch indices

```shell
curl -X GET "http://${ELASTICSEARCH_HOST}:${PORT}/_cat/indices?v"
```

## Repair

### Increase the timeout settings for Elasticsearch to allow more time for requests to complete.

```shell
bash
#!/bin/bash

# Set the Elasticsearch timeout value (in milliseconds)
es_timeout=${TIMEOUT_VALUE}

# Update the Elasticsearch configuration file to increase the timeout value
sudo sed -i "s/.*timeout:.*/timeout: ${es_timeout}/" /etc/elasticsearch/elasticsearch.yml

# Restart the Elasticsearch service to apply the new configuration
sudo systemctl restart elasticsearch.service
```
