Components

This section provides detailed explanations of the functions, command-line parameters, configuration parameters, etc., of the main product components in TDengine.

📄️ taosd

taosd is the core service of the TDengine database engine, and its configuration file is by default located at /etc/taos/taos.cfg, but you can also specify a configuration file in a different path. This section provides a detailed introduction to the command-line parameters of taosd and the configuration parameters in the configuration file.

📄️ taosc

The TDengine client driver provides all the APIs needed for application programming and plays an important role in the distributed computing across the entire cluster. In addition to the API and its specific parameters, the behavior of the client driver can also be globally controlled through a configuration file. This section lists the configuration parameters that can be used by the TDengine client. Some parameters take effect for Native connections, while others apply to WebSocket connections. Please note the distinction when using them.

📄️ taosAdapter

taosAdapter is a companion tool for TDengine, serving as a bridge and adapter between the TDengine cluster and applications. It provides an easy and efficient way to ingest data directly from data collection agents (such as Telegraf, StatsD, collectd, etc.). It also offers InfluxDB/OpenTSDB compatible data ingestion interfaces, allowing InfluxDB/OpenTSDB applications to be seamlessly ported to TDengine.

📄️ taosX

taosX is a core component of TDengine Enterprise, providing the capability of zero-code data access. taosX supports two modes of operation: service mode and command line mode. This section discusses how to use taosX in these two ways. To use taosX, you must first install the TDengine Enterprise package.

📄️ taosX Agent

TDengine taosX Agent is used when TDengine TSDB cannot access a data source directly, for example due to network restrictions. In such cases, you deploy taosX Agent close to the data source or on the same machine as the data source. taosX Agent reads data from the data source and passes it to taosX within your TDengine TSDB cluster.

📄️ taosKeeper

taosKeeper is a monitoring metric export tool for TDengine version 3.0, which can obtain the running status of TDengine with a few simple configurations. taosKeeper uses the TDengine RESTful interface, so there is no need to install the TDengine client to use it.

📄️ taosExplorer

taosExplorer is a web service that provides users with a visual management interaction tool for TDengine instances. Although it is not open source, it is provided for free with the open source version installation package. This section mainly discusses its installation and deployment. All its features are based on a simple and easy-to-use graphical interface, which you can try directly. If needed, you can also refer to the related content in the advanced features and operation and maintenance guide. To ensure the best experience when accessing taosExplorer, please use Chrome version 79 or above, or Edge version 79 or above.

📄️ Configuration Parameter Scope

This document compares the configuration parameters of taosd (server-side) and taosc (client-side) in TDengine TSDB, clearly identifying the scope of each parameter.

📄️ TDinsight

TDinsight is a monitoring solution for TDengine using [Grafana].
