When I tried using aliases I got random read failures so I stopped using
them and instead implemented "aliases" in my polling script:
------------------------------------------------------
my %sensors = (
"28.EC30A5020000" => "bedroom1",
"28.154BA6020000" => "bedroom2",
"28.6618A7020000" => "bedroom_master",
"28.B844A9020000" => "garage",
"28.CE4892020000" => "breakfast_nook"
);
foreach my $sensor (keys %sensors) {
if (!open SENSOR, "/owfs/$sensor/temperature") {
print STDERR "Can't open temperature file for sensor $sensor:
$!\n";
next;
}
my $temperature = <SENSOR>;
close SENSOR;
$temperature =~ s/ *//; # " 82.7375" -> "82.7375"
$output .= "$sensors{$sensor}:$temperature ";
}
------------------------------------------------------
(This produces output that can be consumed by a Cacti external poller
script.)
This has been very stable for me. I first reported the problem of read
failures when using aliases in this message, but I never heard from
anyone on it:
