This is an Android application that takes the x-y-z axis metrics from your phone accelerometer and then sends this data to your InfluxDB.

A logger for logging OPCUA data to InfluxDB (and possibly other later). Has been running in production in several factories since mid 2016.

statsd-jvm-profiler is a JVM agent profiler that sends profiling data to StatsD. Inspired by riemann-jvm-profiler, it was primarily built for profiling Hadoop jobs, but can be used with any JVM process.

This program interfaces ham radio APRS-IS servers and saves packet data into an influxdb database. aprs2influxdb handles the connection, parsing, and saving of data into an influxdb database from APRS-IS using line protocol formatted strings. Periodically, a status message is also sent to the…

Gatling is a load testing framework and traffic generation engine used to measure response times and error rates under heavy load. It functions as an as-code testing library, allowing users to define high-volume traffic simulations and performance tests through programming languages rather than graphical interfaces. The system enables multi-language load simulation and the ability to model concurrent user traffic to identify infrastructure bottlenecks and stability limits. It supports a test-as-code workflow, where version-controlled scripts are integrated into build pipelines as performance

cAdvisor is a container resource monitoring agent and performance analyzer that collects and exports CPU, memory, network, and disk usage statistics from running containers. It functions as a telemetry tool for discovering containers across various runtimes and serves as a Prometheus-compatible metrics exporter. The agent distinguishes itself by analyzing Linux control groups to provide visibility into resource consumption and limits. It utilizes kernel perf events and NUMA statistics for low-level hardware performance tracking and diagnostics, and it can identify out-of-memory kill events th

Telegraf is a modular, cross-platform telemetry pipeline designed to collect, process, and route metrics from diverse infrastructure, applications, and hardware. It functions as a server-side middleware that normalizes heterogeneous data into a unified format, enabling consistent monitoring across complex environments. By utilizing a plugin-driven architecture, the agent manages the entire lifecycle of telemetry data from initial ingestion to final transmission. The project distinguishes itself through a declarative, configuration-driven execution model that allows users to define complex dat

Heapster enables Container Cluster Monitoring and Performance Analysis for Kubernetes (versions v1.0.6 and higher), and platforms which include it.

k6 is a developer-centric load testing suite and command-line load generator designed for network performance validation. It functions as a JavaScript load testing tool that utilizes a Go-based runtime engine to simulate concurrent user traffic and validate API responses across HTTP, gRPC, and WebSockets. The project distinguishes itself by using code rather than a graphical interface to define workload scenarios and performance thresholds. It features a pluggable protocol architecture and an extension ecosystem that allows for the addition of custom protocols and specialized testing capabili

Logs and metrics are one! Professional logging, metrics and analytics for your apps.

DEPRECATED: Data collection and processing made easy.

Glances is a cross-platform system monitoring tool designed to track real-time resource usage and hardware health metrics across diverse computing environments. It functions as a command-line utility that provides a unified view of system performance, identifying bottlenecks and maintaining infrastructure stability through a consistent abstraction layer that translates kernel calls into actionable data. The project distinguishes itself through its distributed capabilities, offering a web-based interface that enables remote access to live performance metrics from any device without requiring d

This is a tool written in Go that helps you do your own custom tailored monitoring, capacity planning and performance debugging of VMware based infrastructures. It collects all possible metrics from vCenters and ESXi hypervisors about hosts, clusters, resource pools, datastores and virtual…

Cernan is a telemetry and logging aggregation server. It exposes multiple interfaces for ingestion and can emit to multiple aggregation sources while doing in-flight manipulation of data. Cernan has minimal CPU and memory requirements and is intended to service bursty telemetry without load…

Influx-capacitor collects metrics from windows machines using Performance Counters. Data is sent to influxDB to be viewable by grafana.

metrics.sh is a lightweight metrics collection and forwarding daemon implemented in portable POSIX compliant shell scripts. A transparent interface based on hooks enables writing custom collectors and reporters in an elegant way.

Riemann is a Clojure-based event stream processor and real-time analytics engine. It functions as a network telemetry pipeline and extensible event router that ingests, transforms, and routes event data from distributed systems. The system uses a domain-specific language to compute metrics and statistical patterns over continuous streams, enabling network trend analysis and real-time alerting. It supports dynamic plugin loading from the classpath and allows for live configuration reloading without interrupting active event streams. Capabilities include centralized telemetry aggregation, even

Logagent is a modern, open-source, light-weight log shipper. It is like Filebeat and Logstash in one, without the JVM memory footprint. It comes with out of the box and extensible log parsing, on-disk buffering, secure transport, and bulk indexing to Elasticsearch, Sematext Logs, and other…

Sematext Agent integrations are built, contributed, and maintained by both the community and Sematext. Like its integrations the Sematext Agent is open-source as well.
