Introduction
An agent is a low-footprint, secure application that runs on managed servers. The agent runs as two (2) OS processes: Agent and Agent Shield.
- On Windows, the agent and agent shield run as Windows services.
- On Linux, they run as OS processes.
Connectivity methods
Agents can be configured to connect to OpsRamp in one of the following ways:
- Connect directly
- Connect via proxy
Connecting directly
Each agent connects to OpsRamp directly over the internet.
This configuration is suitable for small environments that do not have a local gateway deployed.
Connecting via proxy
Each agent connects to OpsRamp via a proxy.
The gateway includes an embedded proxy and is the recommended proxy for this configuration. This configuration is recommended for large environments. With this configuration, you avoid opening outbound access for each agent.
Outbound connectivity requirements
| Requirement | Purpose |
|---|---|
| TCP port 443 | To connect to OpsRamp via its public IP addresses (link below), if the agents are configured to connect directly. |
| TCP port 3128 | To connect to OpsRamp, via the gateway's embedded proxy, if configured in this setup. |
