I am using a simple translate plugin to mark a device as access switch or not and is working ..But in the list if the device entry is "mnvt542ges02" but the input hostname comes as "MNVT542GES02" it does not match ..Basically how can make the translate non case sensitive ??
dictionary_path => "/etc/logstash/switches.csv"
field => "hostname"
destination => "Access_switch"
fallback => "No"
refresh_interval => 86400
