This program scrapes /proc directory and gathers system-wide metrics and pid metrics about memory and cpu usage. Exports data as prometheus metrics or json (server sent events). This doesn't calculate the CPU time but shows utilization for each core.
Based on information gathered from Linux kernel manpage
You can provide your configuration file using --config-path=/some/path/config.toml or just place the config file in the same directory where your binary is.
If you don't provide config.toml configuration file default values are being used.
port = 80
enable_api = false
enable_prometheus = false
If you enable the json api then you should connect to it like this using /sse url path. (Javascript web)
const sse = new EventSource("/sse");
sse.onmessage = (evt) => {
console.log(evt.data);
};
If you want to use prometheus just use default /metrics url path.
Make sure to install Deno and that should be enough. This application is using some deno features that are currently unstable.
Default path for building the binary is <project_root>/out/bin.
To build run:
make build
Running in development
make run
