An agent is a low-footprint, secure application that runs on managed servers. The agent runs as two OS processes: Agent and Agent Shield.

  • On Windows, the Agent and Agent Shield run as Windows services.
  • On Linux, the Agent and Agent Shield run as OS processes.

Connectivity methods

Agents can be configured to connect to OpsRamp in one of the following ways:

  • Connect directly
  • Connect using proxy

Connecting directly

Each Agent connects to OpsRamp directly over the internet. The direct connection configuration is suitable for small environments that do not have a local gateway deployed.

Connecting using proxy

Each Agent connects to OpsRamp using a proxy. The gateway includes an embedded proxy and is the recommended proxy for this configuration. The proxy connection configuration is recommended for large environments. When you connect the Agent using a proxy, you avoid opening outbound access for each agent.

Outbound connectivity requirements

RequirementPurpose
TCP port 443To connect to OpsRamp using its public IP addresses, if the agents are configured to connect directly.
TCP port 3128To connect to OpsRamp, using the gateway's embedded proxy.
Agent and gateway connectivity requirements

We recommend the following minimum hardware required for agents:

  • 2 Virtual CPUs
  • 2 GB RAM
  • 200 MB free disk space
  • 1 NIC
