The OnSight vCollector is a lightweight appliance that functions similarly to our public monitoring nodes, which runs uptime checks and synthetic monitoring against your publicly available servers and web endpoints. However, the OnSight vCollector sits within your private network and monitors resources that are not publicly exposed. The OnSight can run uptime and synthetic checks on your private infrastructure, monitoring things like RDP, database connectivity, and port availability.

The OnSight can also function as a proxy for servers that have the Server Agent installed but have no outbound connectivity. Also, the OnSight can monitor network devices, storage arrays, VMWare clusters, and private network-managed cloud resources such as RDS and DynamoDB.

The OnSight is a collection of Docker containers that provide the necessary services. During the installation of the OnSight, if Docker is not found on the target machine it will automatically be installed.
