[mrtg] Re: MRTG and QuickPage

[Dannie M. Stanley]

I am new to SNMP but I am pretty sure you could use SNMP to do this and 
bypass MRTG.  If you are using Linux/Unix a quick shell script should do 
the trick... here is some code that requires SNMP (command line tools) 
and Perl:


   #!/usr/bin/perl

   $hostname = "myhost";
   $community = "public";
   $testWhichValue = "tcp.tcpOutSegs.0"; # Might need a diff object
   $snmpThresh = 2; # some number
   $EmailAddress = "5555551212\@mymobileprovider.net";

   $snmpGet = `snmpget $hostname $community $testWhichValue`;


   if($snmpGet =~ /^.*:\s*(\d{1,})\s*$/){
     $snmpVal = $1;
     }

   if($snmpVal >= $snmpThresh){
     `echo \"my value is being exceeded\" |mail -s Alert $EmailAddress`;
     }

   exit 0;

You may also be able to set an SNMP trap depending on your device.
