Not just the typical two-OID Get-Request that MRTG build.
You can't get much more than about 30 OIDs in the GET-REQUEST SNMP PDU before you run out of room. > Thanks for any advice. If I had to do this, I would write a program that does a bulk-get (the SNMP_Util.pm module automatically uses bulk-get when you call snmpwalk and are using SNMP v2c). That would store the values somewhere. Then I would write another program to pull the values two at a time into mrtg. Maybe combine them into something that wrote a little cache file if the cache was more than 100 seconds old and just looked in the cache the rest of the time. -- Daniel J McDonald <[EMAIL PROTECTED]> Austin Energy -- Unsubscribe mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/mrtg FAQ http://faq.mrtg.org Homepage http://www.mrtg.org WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
