Data Volume Monitor

Data Volume Monitor is an Unraid plugin for interface traffic accounting with vnStat. It displays network usage and can run configured notifications, Docker operations, VM network-link changes, and custom functions when limits change state. It is maintained by alexphillips-dev.

The first stable release is 2026.11.04.11, with the full cumulative change list from the original plugin in its release notes. Stable (main) and Development (dev) share the same dvm identity. Use Stable for the published release or Development to test subsequent changes. Read the installed version/channel before following these guides. Live host acceptance remains separate from automated validation.

Traffic belongs to interfaces. Matching a container or VM supplies a label; it does not create independent application-level accounting. Virtual interfaces can change when workloads restart, so prefer physical interfaces for important automation.
