Released: 20 July 2023
Highlights Copied
These are the highlights of this release:
-
The ITRS Infrastructure Agent has successfully passed beta testing and can now be used as a stable alternative to the Opsview and NSClient agents. We recommend that new and existing users use the ITRS Infrastructure Agent for new monitoring deployments, even though the Opsview Agent is still supported and available.
-
You can download pre-built packages of the Infrastructure Agent from the Agents Downloads website, or you can build the agent from source on ITRS Infrastructure Agent GitHub.
Note
The Infrastructure Agent can be used on monitored hosts with older Opsview versions, even if you do not upgrade to the latest version. However, we recommend that you upgrade to the latest version of Opsview to ensure that all changes, including security fixes and new features, will work correctly with the Infrastructure Agent.
