Prometheus
The Prometheus output module turns your system into a web server that hosts values in a format that can be read by Prometheus.
The URL to read is http://servername/prometheus.
This is a service module - meaning that rather than writing data to another system, it opens a server to make that data available to systems that might want to read the information.
| Parameter | Default | Meaning |
|---|---|---|
| port | The port number to host the web server on. | |
Notes
It is important to note that if you have multiple output modules that require a web server, they will share a single server with the port number specified by the last module in your configuration file.
For example, if you wanted both Prometheus output on port 90 and REST output on port 9002 (in that order), your Prometheus endpoint would be available on port 9002 rather than 90.
Availability
This module is only available for key-value data.
Example
[
{
"method": "prometheus",
"port": 82
}
]
The above example would make your data available via OPC-UA on port 703
