# kepware-opc-telegraf
|
|
|
|
Generate a **Telegraf** config file to ingest **OPC-UA** data based on a **KEPServerEX** project file.
|
|
|
|
The generated config includes two inputs, one based on `opcua_listener` (event-based, instant updates, no initial values or periodic polling) and one based on `opcua` (polling-based, slow, but provides initial values and outputs a value at least every `interval`).
|
|
|
|
|
|
## Inputs
|
|
|
|
- **kepware_export.xml** - list of OPC nodes from KEPServerEX (see below)
|
|
- **base_telegraf.conf.toml** - base Telegraf conf (should contain at least one of `inputs.opcua` or `inputs.opcua_listener`)
|
|
- **generated_telegraf.conf.toml** - path where to save the generated Telegraf conf
|
|
|
|
## Getting the project file
|
|
|
|
Open **KEPServerEX**, go to File > Save as > select XML in the file type dropdown. Save it as `kepware_export.xml`.
|
|
|
|
## Base Telegraf configuration
|
|
|
|
You'll need to configure the base Telegraf config according to your setup. This probably means changing at least `outputs.influxdb_v2.{urls,organization,bucket,token}`.
|
|
|
|
You will also need to set your OPC-UA connection parameters in both of the input config blocks. If you want to disable one of the inputs, remove or comment out the entire block.
|
|
|
|
## Running the converter
|
|
|
|
If you're running from source, build it first:
|
|
|
|
```sh
|
|
go build
|
|
```
|
|
|
|
Once you have the executable:
|
|
|
|
```sh
|
|
./kepware-opc-telegraf kepware_export.xml base_telegraf.conf.toml generated_telegraf.conf.toml
|
|
```
