I'm looking for a pretty-print of an Ubuntu process with python. I'm getting to know psutil but any idea if there is something better?

Question

I've looked about the psutil library (https://code.google.com/archive/p/psutil/wikis/Documentation.wiki) and got some useful things like

```

PROCESS_ATTRS = ['username', 'cpu_num', 'num_ctx_switches', 'pid', 'memory_full_info', 'connections', 'cmdline', 'create_time', 'ionice', 'num_fds', 'memory_maps', 'cpu_percent', 'terminal', 'ppid', 'cwd', 'nice', 'status', 'cpu_times', 'io_counters', 'memory_info', 'threads', 'open_files', 'uids', 'num_threads', 'exe', 'name', 'gids', 'cpu_affinity', 'memory_percent', 'environ']
for proc in psutil.process_iter():
    print("Querying process: %s [%s]" % (proc.name(), proc.pid))
    print proc.as_dict(attrs=PROCESS_ATTRS)

```

Is there any other library for this, or any useful methods about psutil that I'm missing?

Thanks in advance!

Answer 1

>>> import psutil
>>> from pprint import pprint as pp
>>> pp([p.info for p in psutil.process_iter(attrs=('pid', 'name'))])
[{'name': 'systemd', 'pid': 1},
 {'name': 'kthreadd', 'pid': 2},
 {'name': 'ksoftirqd/0', 'pid': 3},
 {'name': 'kworker/0:0H', 'pid': 5},
 {'name': 'rcu_sched', 'pid': 7},
 {'name': 'rcu_bh', 'pid': 8},
 {'name': 'migration/0', 'pid': 9},
 {'name': 'watchdog/0', 'pid': 10},
 {'name': 'watchdog/1', 'pid': 11},
 {'name': 'migration/1', 'pid': 12},
 {'name': 'ksoftirqd/1', 'pid': 13},
 ...
