Nacitam nejake info v php z MT pres snmp, ale nejak nevim jak funguje OID. Kdyz si ho vypisu treba > /system resource print oid , zjistim treba pro cpu ".1.3.6.1.2.1.25.3.3.1.2.1", ale to nejde, dude vypise seznam vseho co se da vypsat, ale jediny na co skript reaguje je ".1.3.6.1.4.1.14988.1.1.1.2.1.3",coz je signal wifi, prefix ".1.3.6.1.4.1.14988.. ma kazda hodnota z MIB i podle dokumentace. Jaka OID se daji pouzit pro jednotlive hodnoty?
<?php
$ip="x.x.x.x";
$community = 'public';
$object_id = '.1.3.6.1.4.1.14988.1.1.1.2.1.3';
$a = snmpwalk($ip, $community, $object_id);
foreach ($a as $val)
{echo "$val <br>";}
?>
