The Clusterer tool maps over the Clusterer OpenSIPS module, allowing full provisioning and monitoring of a cluster of OpenSIPS servers.
The tool provide standard provisioning operations like adding, editing and deleting nodes from the OpenSIPS clusteres - all these are DB operations. To push your changes into OpenSIPS you need to force OpenSIPS to DB reload by using the Reload on server button.
Tool specific settings are configurable via the setting panel - see gear-icon in the tool header.
All settings are explained via ToolTip and have format validation.
