Hi, Thank you for bringing this up and all the improvements Florian! Golang seems to gain more popularity for quite a lot cloud native software, it makes sense to have this type of plugins integrated well. I'm sure there will be interest in contributing to those. I like the idea you have described below with central community repository, with similar thoughts around. Best regards, KK

I think it makes sense to support Go plugins. While I can't speak about Go directly, maintaining a Rust crate [0] for creating collectd plugins over the years has taught me that there are some benefits to out-of-band plugins compiled to shared objects: - More rapid plugin releases (especially new plugins) that don't need to be tied to the main release - Being able to have a plugin target collectd versions prior to its existent. For instance, the rust crate allows one to compile to a shared object that is compatible with either 5.4, 5.5, or 5.7+'s collectd plugin API. So in effect, new plugins can be backported to older collectd installations. I don't know if those are in accordance with your thoughts, but I feel like allowing Go plugins could also lower the barrier to entry for contributors. Thanks -Nick.

Hi everybody, TL,DR: Should we create a new Git repository and maintain plugins written in the "Go" programming language? the last days, I spent some time improving the "collectd.org/plugin" package [0]. In a nutshell, it allows to implement a plugin in Go, compile it to a shared object and then load it like other "native" (implemented in C) plugins. The primary benefit over approaches such as the "collectd.org/exec" [1] and "collectd.org/rpc" [2] packages is, that it supports implementing "write" and "log" callbacks. "config" callbacks, allowing one to configure the plugin via the collectd config file, are work in progress. My question is: Should we attempt to maintain plugins written in Go? And if so, how? For Go-based plugins, i.e. plugins based on "collectd.org/plugin", I propose we create a separate repository, e.g. github.com/collectd/go-plugins, and maintain those there. This would make plugins easier to discover for users, allow easier changes to the API, and strive for consistency across the ecosystem. In the past, we have imported plugins in non-C languages into the main repository, in particular bindings/perl/ and bindings/java/. This model is not a good fit for Go, which makes much more assumptions about the directory structure of a repository. Also, for Perl and Java the "glue code" (code translating between Perl and Java, and C) is contained in the "main" reposiroty; that's not the case for Go. I'm also contemplating if we should try to support plugins using the "exec plugin" more, e.g. by creating a repository for them. There are a number of "collectd Docker" plugins and I feel like this duplication could have been avoided by better discoverability.
