Checkly allows users to create Private Locations to monitor resources deployed inside their own network, which are not accessible from public locations. To do this, users can deploy an agent inside their network using Checkly's Private Locations agent. This enables monitoring of private resources such as AWS RDS, Elasticsearch, and Elasticache, with reduced latency compared to public locations. Users can install and run the Checkly agent locally or use Terraform to create a container instance in AWS, and then add checks to monitor specific resources. The Checkly Terraform Provider allows users to easily create checks for private resources using a YAML file, which is configured using Goss. Additionally, users can create dashboards to visualize their check results, making monitoring infrastructure an appealing and cost-effective solution.
