# tos-mviz(1)

Launch MViz, the TinyOS network visualizer

## NAME

tos-mviz - Launch MViz, the TinyOS network visualizer

## SYNOPSIS

**tos-mviz** \[**-comm** *serial-source*\] *mig-class* \[*mig-class\]...*

## DESCRIPTION

**tos-mviz** launches MViz, the TinyOS network visualizer. MViz is a replacement for the Surge application of earlier TinyOS versions. MViz reads packets from a packet source and displays their data in a GUI. MViz takes the class names of mig-generated Java classes as parameters; it parses these packets and displays their fields. For MViz to be able to understand a mig packet, it must have an *origin* field which denotes which node the data is from. Please see TinyOS tutorial 12: MViz, for more detail.
