OpenTSDB is a distributed time-series database designed to store and retrieve numerical measurements collected from servers, applications and network infrastructure. It uses Apache HBase as its storage backend, allowing time-series data to be maintained across a distributed database system.
The software is intended for environments that generate large numbers of measurements over extended periods. Each observation consists of a metric, timestamp, value and associated tags, giving users a way to distinguish measurements collected from different systems or services.
OpenTSDB provides interfaces for submitting data and retrieving historical measurements. Its query capabilities support operational monitoring, capacity planning and the examination of trends across infrastructure.
This is free and open source software.
Key Features
- Store timestamped numerical measurements in Apache HBase.
- Organise metric series using names and associated key-value tags.
- Accept incoming measurements through a network protocol and HTTP API.
- Query stored time-series data through HTTP requests.
- Aggregate measurements over configurable time intervals.
- Filter metric series according to tag values and query expressions.
- Apply supported aggregation and downsampling functions when retrieving data.
- Retrieve multiple metric series within a single query.
- Generate graphical representations of time-series data.
- Support asynchronous event ingestion through its processing architecture.
- Use distributed HBase storage to accommodate large collections of measurements.
- Configure retention and data handling through the underlying storage environment.
- Extend functionality through supported plugins.
- Provide interfaces for integration with external monitoring and graphing applications.
