The communications between Orion Server and the agent are fully encrypted using 2048-bit or 3072-bit Transport Layer Security (TLS) encryption, based on the agent and certificate versions.

Server-Initiated – The Orion server communicates with the remote Agent via port 17779 (All Operating Systems).

Agent-Initiated – The Agent initiates communication back to the Orion server via port 17778 (Windows and Linux).

Monitoring data retention during network outages between SolarWinds and the monitored host (up to 24 hours).Īfter completion of the Agent installation on the remote system, the Orion server communicates with the Agent in one of two ways:.

Polling nodes across domains where there are no domain or forest trusts.

Requirements for secure communication between the Orion server and monitored system.

Requirements of using a single TCP port versus WMI that uses random open ports in the operating system.

Monitoring hosts and applications behind firewall NAT or proxies.

Inability to use WMI in certain secure environments.Agents are commonly used as an alternative to WMI or SNMP to provide information about your system for several reasons such as:

How the Agent Provides Database Information on a Microsoft SQL ServerĪn Agent is a software application that provides a communication channel between the Orion server and a monitored system.

How to Modify the Local Account on the Remote Windows System.
