I’d like to use fabric as a tool to gather all server loads and process the values afterward, I thought of something like this:

from fabric.api import run

for servername in servernames:
    load_str = run('cat /proc/loadavg | cut -d' ' -f1', host=servername)

but fabric doesn’t allow me to specify the hostname this way, I found this IMO ugly way:

from fabric.api import env, run

for servername in servernames:
    env.host_string = servername
    load_str = run('cat /proc/loadavg | cut -d' ' -f1')

are there more elegant ways?

Using paramiko directly, as suggested here pushes me to write an own module that abstracts it – quoting from fabrics website, that’s exactly what fabric should do for me:

In addition to use via the fab fool, Fabric’s components may be imported into other Python code, providing a Pythonic interface to the SSH protocol suite at a higher level than that provided by e.g. Paramiko (which Fabric itself leverages.)
