Methods

Method	Description
List(ctx, hostname)	List all running processes on the target
Get(ctx, hostname, pid)	Get information about a process by PID
Signal(ctx, hostname, pid, opts)	Send a signal to a process by PID

Request Types

Type	Fields
ProcessSignalOpts	Signal (string, e.g. TERM, KILL)

Usage

import "github.com/osapi-io/osapi/pkg/sdk/client"

c := client.New("http://localhost:8080", token)

// List all processes
resp, err := c.Process.List(ctx, "web-01")
for _, r := range resp.Data.Results {
    for _, p := range r.Processes {
        fmt.Printf("PID=%d name=%s cpu=%.1f%%\n",
            p.PID, p.Name, p.CPUPercent)
    }
}

// Get a specific process
resp, err := c.Process.Get(ctx, "web-01", 1234)
for _, r := range resp.Data.Results {
    for _, p := range r.Processes {
        fmt.Printf("PID=%d user=%s state=%s\n",
            p.PID, p.User, p.State)
    }
}

// Send TERM signal to a process
sigResp, err := c.Process.Signal(ctx, "web-01", 1234,
    client.ProcessSignalOpts{Signal: "TERM"})
for _, r := range sigResp.Data.Results {
    fmt.Printf("PID=%d signal=%s changed=%v\n",
        r.PID, r.Signal, r.Changed)
}

// Broadcast process list to all hosts
resp, err := c.Process.List(ctx, "_all")
