Carbon is a backend data caching and persistence daemon for Graphite. Carbon is responsible for receiving metrics over the network, caching them in memory for "hot queries" from the Graphite-Web application, and persisting them to disk using the Whisper time-series library.

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

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

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

StatsD is a friendly front-end to Graphite. This package provides a simple Python client for the StatsD daemon.

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 file system monitor.

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 (server-side)

This package provides a Prometheus exporter for PostgreSQL server metrics.

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.

Whisper is one of three components within the Graphite project. Whisper is a fixed-size database, similar in design and purpose to RRD (round-robin-database). It provides fast, reliable storage of numeric data over time. Whisper allows for higher resolution (seconds per point) of recent data to degrade into lower resolutions for long-term retention of historical data.

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 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.

pw is Pipe Watch, a utility that continuously reads lines of text from a pipe or pipe-like source, passes them through a FIFO buffer, and maintains a display based on the occasional sampling of the contents of the FIFO buffer, with useful features such as triggering and filtering.

With pw you can:

• Interactively apply and remove filters on-the-fly, without interrupting the source.

• Make recurring patterns in the stream appear to ``freeze'' on the screen, using triggers.

• Prevent the overwhelming amount of output from a program from flooding the terminal, while consuming all of that output so that the program isn't blocked. pw can pause its display updates entirely.

• Juggle multiple shell background jobs that produce output, yet execute indefinitely without blocking. When pw runs as part of a shell background job, it continues to consume input, process filters and take snapshots, without displaying anything. When put into the foreground again, display resumes.

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.

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.

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.

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

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.
