rstat

Library rstat provides basic functionality for periodical health check of IoT devices running Linux. It has an API for invoking ps command on a remote device via ssh, returning a process tree with the requested metrics for each process.

Usage example:

// compose ssh command with the given ip, user, password and timeout in seconds
ssh := rstat.SSHCommand("192.168.0.16", "pi", "raspberry", 5)
// request process tree with 3 metrics per process
root, err := rstat.ProcTree(ssh, "%cpu", "%mem", "cmd")

if err != nil {
	return err
}

// iterate the process tree
root.ForEach(func(node *rstat.ProcNode) {
	// just for example, print the metrics
	fmt.Printf("%d %s %s %s %q\n", node.Pid, node.ParentPid, node.Stats["%CPU"], node.Stats["%MEM"], node.Stats["CMD"])
})
