Agents

The Agents page displays the Agents that are registered with Tripwire.io. An Agent is installed on each asset to be monitored and regularly checks the status of that asset.

An Agent scans the asset where it is installed once a day, using an appropriate CIS policy for its operating system.
Tripwire Anyware SCM automatically pushes updates to Agents whenever CIS updates a policy.
Whenever a policy is updated, the Agent immediately scans the asset with the new policy.

Click an Agent on this page to see details (hostname, IP address, OS, etc) about the Agent and the asset where it is installed.

Note:	For an overview of how Tripwire Anyware SCM works, see Getting Started.

The Agent Health column shows each Agent's current state:

Good: The Agent is scanning with the latest policy.
Warning: The Agent is scanning, but the Agent’s policy is not the latest version.
Bad: Something is wrong. Check the Agent’s Details for more information.
Unknown: The Agent has not communicated with Tripwire.io recently. Check the Agent’s Details for the Last Communicated time.
