The prometheus_client package supports exposing metrics from software written in Python, so that they can be scraped by a Prometheus service.

Metrics can be exposed through a standalone web server, or through Twisted, WSGI and the node exporter textfile collector.

This package contains a Prometheus exporter for the TEMPer sensor devices.

zabbix-cli is a command-line client for the Zabbix monitoring system. It can configure and display various aspects of Zabbix through a text-based interface.

This package provides a distributed monitoring solution (client-side agent)

darkstat is a packet sniffer that runs as a background process, gathers all sorts of statistics about network usage, and serves them over HTTP. Features:

• Traffic graphs, reports per host, shows ports for each host.

• Embedded web-server with deflate compression.

• Asynchronous reverse DNS resolution using a child process.

• Small. Portable. Single-threaded. Efficient.

• Supports IPv6.

Nagios is a host, service, and network monitoring program written in C. CGI programs are included to allow you to view the current status, history, etc. via a Web interface. Features include:

• Monitoring of network services (via SMTP, POP3, HTTP, PING, etc).

• Monitoring of host resources (processor load, disk usage, etc.).

• A plugin interface to allow for user-developed service monitoring methods.

• Ability to define network host hierarchy using "parent" hosts, allowing detection of and distinction between hosts that are down and those that are unreachable.

• Notifications when problems occur and get resolved (via email, pager, or user-defined method).

• Ability to define event handlers for proactive problem resolution.

• Automatic log file rotation/archiving.

• Optional web interface for viewing current network status, notification and problem history, log file, etc.

Prometheus exporter for metrics exposed by *NIX kernels, written in Go with pluggable metric collectors.

Prometheus exporter for metrics exposed by *NIX kernels, written in Go with pluggable metric collectors.

collectd gathers metrics from various sources such as the operating system, applications, log files and external devices, and stores this information or makes it available over the network. Those statistics can be used to monitor systems, find performance bottlenecks (i.e., performance analysis) and predict future system load (i.e., capacity planning).

This package provides a daemon that monitors device power levels, notifying the user and optionally running a command when it reaches user-configured power thresholds. This can be used to force powering off a laptop when the battery gets below critical levels, instead of damaging the battery.

This package provides a utility to report system wide file access events from all running processes. Its main purpose is to find processes which keep waking up the disk unnecessarily and thus prevent some power saving.

This package provides a distributed monitoring solution (client-side agent)

pyzabbix is a Python module for working with the Zabbix API.

HostScope displays key system metrics of Linux hosts, such as detailed CPU load, speed and temperature, I/O rates of network interfaces, I/O rates of disks, and user process summary information. All metrics are multicast on the LAN, if wanted, and clients can switch between multiple hosts on the network. Hostscope features a bridge to Influx DB. So Grafana can be used to visualize the recorded data over time.

dgop is a system monitoring tool. It supports cursor-based sampling of CPU/memory/disk/network, plus an optional REST API server. It supports cursor-based sampling for building real-time monitoring tools like htop. Instead of relying on instantaneous snapshots, it may track system state changes over time for more accurate CPU usage calculations and network/disk rates.

Moreutils is a collection of general-purpose command-line tools to augment the traditional Unix toolbox.

GNU Motti is a simple multiplayer strategy game played in a terminal. The objective of the game is to conquer enemy capitals by occupying and encircling territory.

Mpc123 is a command-line player for files in the Musepack audio compression format (.mpc files).

MP3Info is a little utility used to read and modify the ID3 tags of MP3 files. MP3Info can also display various technical aspects of an MP3 file including playing time, bit-rate, sampling frequency and other attributes in a pre-defined or user-specifiable output format.

Id3lib is a cross-platform software development library for reading, writing, and manipulating ID3v1 and ID3v2 tags. It is an on-going project whose primary goals are full compliance with the ID3v2 standard, portability across several platforms, and providing a powerful and feature-rich API with a highly stable and efficient implementation.

RipperX is a GTK program to rip CD audio tracks and encode them to the Ogg, MP3, or FLAC formats. Its goal is to be easy to use, requiring only a few mouse clicks to convert an entire album. It supports CDDB lookups for album and track information.

TagLib is a C++ library for reading and editing the meta-data of several popular audio formats. Currently it supports both ID3v1 and ID3v2 for MP3 files, Ogg Vorbis comments and ID3 tags and Vorbis comments in FLAC, MPC, Speex, WavPack TrueAudio, WAV, AIFF, MP4 and ASF files.

Wavbreaker is a WAV and MP3 file splitter. It can be used to break up a WAV or MP3 audio file into multiple WAV files. Wavbreaker contains a helpful waveform display of the audio file being edited, to help the user in splitting the file at the right point. Wavbreaker also supports splitting MP3 files without re-encoding them, to preserve their original audio quality.

eyeD3 is a Python tool for working with audio files, specifically mp3 files containing ID3 metadata (i.e. song info). It provides a command-line tool (eyeD3) and a Python library (import eyed3) that can be used to write your own applications or plugins that are callable from the command-line tool.
