InfluxDB – Time Series Database

InfluxDB is a high-performance time series database designed for handling high write and query loads. Built specifically for metrics, events, and real-time analytics, it provides the storage backbone for modern monitoring systems.

Key Features

• Purpose-Built: Optimized for time series data
• Flux Query Language: Powerful data scripting language
• Data Retention: Automatic data lifecycle management
• High Performance: Millions of writes per second
• Cardinality Handling: Efficient high-cardinality storage

Installation

Install InfluxDB on Ubuntu:

wget https://dl.influxdata.com/influxdb/releases/influxdb2-2.7.1-amd64.deb
sudo dpkg -i influxdb2-2.7.1-amd64.deb
sudo systemctl enable influxdb
sudo systemctl start influxdb

Usage Examples

Query data with Flux:

from(bucket: "monitoring")
  |> range(start: -1h)
  |> filter(fn: (r) => r._measurement == "cpu")
  |> mean()

Benefits

InfluxDB provides the ideal storage layer for observability data. Its native time series capabilities outperform general-purpose databases for metrics workloads, while Flux enables complex data transformations.
