Axibase Time Series Database is a non-relational database optimized for collecting, storing, and analyzing temporal data from IT infrastructure, industrial equipment, smart meters, and IoT devices.
ATSD requires a Java 8 runtime environment and is supported on major Linux distributions in 64-bit mode.
A single-node ATSD instance can process up to 200,000 metrics per second with millisecond accuracy and handle out-of-order sample writes without any loss of numeric precision.
The number of metrics inserted per second can be increased by adding region servers to the underlying HBase cluster.
Storage efficiency ultimately determines how many metrics and individual series can be stored in the system.
Compared to traditional databases, ATSD requires up to 50 times less disk space. Refer to compression tests for more details.
The storage capacity can be scaled by adding data nodes to the underlying HDFS cluster. With ATSD on AWS EMR, storage capacity is right-sized automatically, independent of processing capacity.
- High-performance metrics backend.
- Consolidated statistics repository.
- Centralized monitoring system.
- EDM database.
- Data Lake component for time series data.
- Econometrics data store.
ATSD is a modular systems which includes the following components in addition to the core storage engine:
- Rule Engine
- SQL Engine
- Portal Server
- Charts Library
- Search Service
- REST API Server
- Network API Server
- CSV Processor
- Upload CSV.
- Stream CSV.
- Stream network commands via TCP/UDP.
- Stream network commands with Kafka.
- Insert data using REST API.
- Insert rows using JDBC driver.
- Use API clients or storage drivers.
- Install pre-integrated collectors/agents.
- Deploy Axibase Collectors to copy data from relational databases, plant historians, and IT infrastructure using open and proprietary protocols.
For more information about inserting data, refer to Writing Data.
ATSD provides an optimized line protocol to insert high volumes of metrics with user-defined dimensions called network commands.
echo "series e:sns-001 m:temperature=15.4 m:rpm=302 t:panel=front" \ > /dev/tcp/atsd_hostname/8081
The commands can be streamed into ATSD on ports
8082/udp or uploaded to the
/api/v1/command REST API endpoint.
The following protocols are supported for extended compatibility:
New entities and metrics are registered by the database automatically and support the collection of data from numerous different domain models in a single extensible schema.
The underlying tables are listed on the Settings > Storage > Database Tables page. Table schemas are self-managed by the database.
| ||Name of the object being monitored.|
| ||Name of the numeric attribute describing the object.|
| ||Timestamped numeric metric value, |
| ||Sequence of |
| ||Custom attribute describing the |
The commands listed below store temperature observations for the bioreactor enclosure
BR1740 located at site
SVL2 in Sunnyvale, as well as room temperature at the same site.
Metadata commands contain descriptive attributes sent initially and on change.
entity e:BR1740 t:type=Bioreactor t:city=Sunnyvale t:site=SVL2 entity e:SVL2 t:type=site t:city=Sunnyvale metric m:Temperature t:units=Celsius
Series commands carry the actual measurements and contain only the series key.
series d:2018-05-20T00:15:00Z e:BR1740 m:Temperature=70.5 t:part=enclosure series d:2018-05-20T00:15:00Z e:SVL2 m:Temperature=25.2 series d:2018-05-20T00:16:00Z e:BR1740 m:Temperature=72.5 t:part=enclosure series d:2018-05-20T00:16:00Z e:SVL2 m:Temperature=25.1 ...
By separating inserted data into metadata and time series data, each type of information is stored and processed separately and thus, more efficiently. Both types of data are readily available and can be accessed in SQL queries and REST API requests.
SELECT datetime, value, entity FROM atsd_series WHERE metric = 'Temperature' AND entity.tags.type = 'Bioreactor' ORDER BY datetime
