TICK Stack

1. Telegraf
Telegraf is the Agent for Collecting & Reporting Metrics & Data
It is part of the TICK stack and is a plugin-driven server agent for collecting and reporting metrics. Telegraf has plugins or integrations to source a variety of metrics directly from the system it's running on, pull metrics from third-party APIs, or even listen for metrics via a StatsD and Kafka consumer services. It also has output plugins to send metrics to a variety of other datastores, services, and message queues, including InfluxDB, Graphite, OpenTSDB, Datadog, Librato, Kafka, MQTT, NSQ, and many others.
2. InfluxDB
InfluxDB is the Time Series Database in the TICK Stack
InfluxDB is used as a data store for any use case involving large amounts of timestamped data, including DevOps monitoring, application metrics, IoT sensor data, and real-time analytics. Conserve space on your machine by configuring InfluxDB to keep data for a defined length of time, automatically expiring & deleting any unwanted data from the system. InfluxDB also offers a SQL-like query language for interacting with data.
