# DATABASE ELASTICSEARCH DataDog monitors
## How to use this module
```hcl
module "datadog-monitors-database-elasticsearch" {
source = "claranet/monitors/datadog//database/elasticsearch"
version = "{revision}"
environment = var.environment
message = module.datadog-message-alerting.alerting-message
}
```
## Purpose
Creates DataDog monitors with the following checks:
- Elasticsearch average index flushing to disk latency
- Elasticsearch average indexing latency by document
- Elasticsearch average Old-generation garbage collections latency
- Elasticsearch average search fetch latency
- Elasticsearch average search query latency
- Elasticsearch average Young-generation garbage collections latency
- Elasticsearch change alert on the average time spent by tasks in the queue
- Elasticsearch change alert on the number of currently active queries
- Elasticsearch change alert on the number of query cache evictions
- Elasticsearch change alert on the number of request cache evictions
- Elasticsearch change alert on the number of search fetches currently running
- Elasticsearch change alert on the total number of evictions from the fielddata cache
- ElasticSearch Cluster has unassigned shards
- ElasticSearch Cluster is initializing shards
- ElasticSearch Cluster is relocating shards
- ElasticSearch Cluster status not green
- ElasticSearch does not respond
- ElasticSearch free space < 10%
- Elasticsearch JVM HEAP memory usage
- Elasticsearch JVM memory Old usage
- Elasticsearch JVM memory Young usage
- Elasticsearch number of current open HTTP connections anomaly detected
