Server Check Installation Files

The Server Check download is a 10-monitor FREE version. The software can be run without registration, allowing HTTP and Ping monitors only, and limits check frequencies to five minutes or more. The software can also be registered for free here to receive a license key which enables all monitor types to be deployed, and removes the 5-minute check restriction.

All other licenses that can be purchased for Server Check can also be applied to the free version to enable more monitors to be deployed.
