On some nodes i have dci that logs packet loss. when node is unreachable i get two alerts, one for node down and another one for high packet loss. Is it possible to mute other dci alerts when node is already unreachable? 

You can make transformation script like this for your packet loss DCI:

if ($node->state & NodeState::Unreachable) abort;
return $1;
"abort" keyword will cancel collection of datapoint. You can also use "return null" instead of "abort" - this will put the DCI into data collection error.

it was giving script errors, so i changed it bit:

if ($node->state & NodeState::Unreachable) {
abort;
}

return true;

Last line
return $1;is there so transformation script returns DCI's value. Currently your DCI return "true" all the time.
