<![CDATA[RegEx in DCI]]>Quick one...

How would you handle regex in the DCI transformation?

Let's say you poll an SNMP OID which returns a string similar to "MyVal=18#-99#AB_01".
You want to extract the "-99" and return an integer to graph it...

In Perl it would sth like $1 ~=/#(.+)#/ - if I'm right.

Solution is...

sub main()
{
   $1~="#(.*)#";
   return $1;
}

This script will return "-99" if I give it as input "MyVal=18#-99#AB_01".
And for those interested...

sub main()
{
    $1~="#(.*)#(.*)$";
    return $2;
}

This one will return "AB_01"

PS.: "main" not "Main"!!! Otherwise -> Error
