Are there examples of external data collection modules written in languages that aren't Python or Go? #15972
-
|
I know Netdata itself collects a lot of system metrics in C, and there are plugin orchestrators for modules written in Go or Python. But are there external plugins that collect in C and send to Netdata without a plugin orchestrator? Or any that use an external database but not one of the provided plugin orchestrators? |

Well, we have a framework for shell scripts for data collection (found here in our source code: https://github.com/netdata/netdata/tree/master/collectors/charts.d.plugin), and we used to have some collectors written in Node.JS (it was removed a while back, but you can see an old copy of the code here: https://github.com/netdata/netdata/tree/v1.34/collectors/node.d.plugin). In general though, we don’t really have much in the way of ‘simple’ external plugins that don’t use our Python or Go frameworks or our internal C API any more. |

Is there a way for external plugins to access the internal C API then? Just wondering since you say "anymore". |

@Ferroin Sorry for the tag; I'm starting to wonder if GitHub notifies you of responses to your response because on the last few questions I've asked, I've gotten one reply and then nothing after that. |

Not really. The internal C API is built around the assumption of in-process messaging.
Yeah, for some reason GitHub doesn’t notify about replies to replies. It’s one of the ore significant limitations of the platform at the moment. |

I think this is an example in bash https://github.com/netdata/community/tree/main/collectors/charts.d.plugin/speedtest And a node.js one https://github.com/netdata/community/tree/main/collectors/node.d.plugin/snmp |

Thank you! GitHub wouldn't let me mark two answers, but I appreciate them both 👍 |
