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 ";}

Tak uz jsem na to asi prisel. Nevim proc, ale nemuze se tam psat to posledni cislo OID.

taky jsme to resili, od nejake trojkove verze to prestalo chodit.. a ve verzi 4.6 uz to zase jde

$host predavej jako IP: napr 10.10.10.10

Muj skript jako napoveda :) chodi na nekterych 3 verzich, snad ti to nejak pomuze. Nepsal sem to vsechno ja, neco je okopirovany, ale dohromady to fakci. :)
