Hi,
i am very beginner using ruby.
i use a application that its name is logstash. it is ruby based monitoring
tool.
it is let use ruby code in its configuration file.
i use this application for snmptrap messages.
these messages contain some key = value sections.
example output raw data:
raw datası:

more readable version.

There is a problem these keys
"VTP-MIB::vtpVlanIndexVlanID.3002" and "IF-MIB::ifName.10027". this field
contains digit section and this section is dynamic.
i want to remove this section on key.
it looks like "VTP-MIB::vtpVlanIndexVlanID" and "IF-MIB::ifName".
how can i do this modification?
i am not good at with ruby. i will push your patient :)
thank you :)
