Operating system(s): Debian-based Linux

Package PPA: ppa:ethz-asl/ros

Description

This project provides system monitoring tools for ROS in the form of the following ROS nodes:

CPU monitor
HDD monitor
Memory monitor
Network monitor
NTP monitor

Each node publishes ROS diagnostics which can conveniently be visualized in the runtime monitor.

Installation

Here, we assume you intend to build/install the project for the ROS distribution named ROS_DISTRO.

Installing from packages (recommended for Ubuntu LTS users)

The maintainers of this project provide binary packages for the latest Ubuntu LTS releases and commonly used system architectures. To install these packages, you may follow these instructions:

Add the project PPA to your APT sources by issuing
```
sudo add-apt-repository ppa:ethz-asl/ros
```
on the command line
To re-synchronize your package index files, run
```
sudo apt-get update
```
Install all project packages and their dependencies through
```
sudo apt-get install ros-ROS_DISTRO-system-monitor
```
or using your favorite package management tool

Building from source

This project may be built using the CMake build system with an open-source macro extension called ReMake.

Installing build dependencies

The build dependencies of this project are available from the standard package repositories of recent Ubuntu and ROS releases. To install them, simply use the command

sudo apt-get install ros-ROS_DISTRO-rospy, ros-ROS_DISTRO-message-generation, ros-ROS_DISTRO-std-msgs, ros-ROS_DISTRO-diagnostic-msgs

Building with ReMake

Preparing the build system

If you already have installed ReMake on your build system, you may skip this step. Otherwise, before attempting to build this project the traditional CMake way, you must install ReMake following these instructions.

Building with CMake

Once ReMake is available on your build system, you may attempt to build this project the CMake way. Assuming that you have cloned the project sources into PROJECT_DIR, a typical out-of-source build might look like this:

Create a build directory using
```
mkdir -p PROJECT_DIR/build
```
Switch into the build directoy by
```
cd PROJECT_DIR/build
```

In the build directory, run

cmake -DROS_DISTRIBUTION=ROS_DISTRO PROJECT_DIR

to configure the build

If you want to inspect or modify the build configuration, issue
```
ccmake PROJECT_DIR
```
Build the project using
```
make
```
If you intend to install the project, call
```
make packages_install
```
(from packages on Debian-based Linux only) or
```
make install
```
