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.

This package provides a distributed monitoring solution (server-side)

This package provides a tray icon for ActivityWatch.

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

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.

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.

Conky is a lightweight system monitor for X that displays operating system statistics (CPU, disk, and memory usage, etc.) and more on the desktop.

This package provides a AFK watcher for ActivityWatch.

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.

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

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.

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 X11 window watcher for ActivityWatch.

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 provide an input watcher for ActivityWatch.

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

This package provides the ActivityWatch server, for secure storage and retrieval of all your quantified self data.

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).

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.

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.

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 Prometheus exporter for PostgreSQL server metrics.

This package provides a wayland window watcher for ActivityWatch.

This package provides a file system monitor.
