The InfluxData Platform is the leading modern time series platform designed from the ground up for metrics and events. It is comprised of four core components: Telegraf, InfluxDB, Chronograf, and Kapacitor (often referred to as the TICK stack). Each fulfills a specific role in managing your time-series data: data collection, data storage, data visualization, and data processing and alerting.
Enterprise versions of InfluxDB and Kapacitor provide clustering, access control, and incremental backup functionality for production infrastructures at scale.
The TICK stack - Open Source Components
Telegraf is a data collection agent that captures data from a growing list of sources and translates it into Line Protocol data format for storage in InfluxDB. It’s “pluggable”, extensible architecture makes it easy to create plugins that both pull and push data from and to different sources and endpoints.
InfluxDB stores data for any use case involving large amounts of timestamped data, including DevOps monitoring, log data, application metrics, IoT sensor data, and real-time analytics. It provides functionality that allows you to conserve space on your machine by keeping data for a defined length of time, then automatically downsampling or expiring and deleting unneeded data from the system.
Chronograf is the user interface for the TICK stack that provides customizable dashboards, data visualizations, and data exploration. It also allows you to view and manage Kapacitor tasks.
Data Processing & Events
Kapacitor is a data processing framework that enables you to process and act on data as it is written to InfluxDB. This includes detecting anomalies, creating alerts based on user-defined logic, and running ETL jobs.
InfluxData Enterprise - Commercial Offerings
InfluxData’s Enterprise offerings allow you to run the TICK stack at scale and provide enterprise-grade features added to our open source components as well as support directly from InfluxData’s support team.
The open source versions of Telegraf and Chronograf can be used in conjunction with either the open source or Enterprise editions of InfluxDB and Kapacitor. Additionally, Telegraf and Chronograf do not require the purchase of an enterprise subscription.
InfluxDB Enterprise provides functionality necessary to run a high-availability (HA) InfluxDB cluster, providing clustering, horizontal scale out, and advanced access controls.
Data is written across nodes using an eventually consistent write model. All writes are added to the Hinted Handoff Queue (HHQ), then written to other nodes in the cluster.
InfluxDB Enterprise’s Anti-Entropy (AE) process ensures data shards in the cluster are in sync. When “entropy” (out-of-sync data) is detected, AE will repair the affected shards, syncing the missing data.
In InfluxDB Enterprise, fine-grained authorization can be used to control access at the measurement or series levels rather than just the database level.
Enterprise meta nodes expose the
/debug/pprof API endpoint that allows you to
profile and potentially diagnose performance bottlenecks in your cluster.
InfluxDB Enterprise allows for incremental backups that write only newly added data to existing backup files rather than backing up all data in a new backup.
Kapacitor Enterprise provides functionality necessary to run a high-availability Kapacitor cluster.
Kapacitor cluster management
Kapacitor Enterprise is packaged with
kapactorctl, a command line client for creating
and managing Kapacitor clusters.
As alerts are triggered in a multi-node Kapacitor cluster, Kapacitor Enterprise deduplicates alert data to prevent duplicate alert notifications from being sent.
Data is passed between InfluxDB and Kapacitor via subscriptions. Kapacitor Enterprise includes configuration options that allow you to encrypt communication between your Kapacitor Enterprise and InfluxDB Enterprise clusters.
