Icinga2 - Tdengine — ContextQMD

import Icinga2 from "../../assets/resources/_icinga2.mdx"

icinga2 is an open-source host and network monitoring software, originally developed from the Nagios network monitoring application. Currently, icinga2 is released under the GNU GPL v2 license.

To store data collected by icinga2 into TDengine, simply modify the icinga2 configuration to point to the corresponding server and port of taosAdapter. This allows full utilization of TDengine's efficient storage and query performance for time-series data and cluster processing capabilities.

Prerequisites

The following preparations are needed to write icinga2 data into TDengine:

TDengine cluster is deployed and running normally
taosAdapter is installed and running normally. For details, please refer to taosAdapter user manual
icinga2 is installed. For icinga2 installation, please refer to official documentation

Configuration Steps

Verification Method

Restart taosAdapter:

shell

sudo systemctl restart taosadapter

Restart icinga2:

shell

sudo systemctl restart icinga2

After waiting about 10 seconds, use the TDengine CLI to query TDengine to verify if the corresponding database has been created and data has been written:
