A simple, terminal-based Erlang dashboard.
erldash connects to an Erlang node using [the dynamic node name feature] (since OTP-23) to collect metrics.
It only depends on [erlang] and [erpc] modules.
So you can use this dashboard out of the box without installing any additional packages to the target Erlang node.
Metrics are collected using [erlang:statistics/1], [erlang:memory/0] and [erlang:system_info/1] functions.
Pre-built binaries for Linux and MacOS are available in the releases page.
console
// An example to download the binary for Linux.
$ VERSION=... # Set the target erldash version such as "0.1.2"
$ curl -L https://github.com/sile/erldash/releases/download/${VERSION}/erldash-${VERSION}.x86_64-unknown-linux-musl -o erldash
$ chmod +x erldash
$ ./erldash
If you have installed cargo (the package manager for Rust), you can install erldash with the following command:
console
$ cargo install erldash
$ erldash
Note that you need to use Rust-v1.58.0 or later to build erldash.
Just execute the following command:
console
$ erldash $TARGET_ERLANG_NODE
If you need to specify a cookie value other than $HOME/.erlang.cookie, please specify that to --cookie option.
