Lookuptable

Translate key to value from file.

Configuration

filter:
  - type: lookuptable
    # Source field to match in lookup table, default: empty
    source: hostname
    # Target field where lookup value is set, default: empty
    target: service
    # File containing lookups, default: empty
    lookup_file: "hosts-lookuptable.txt"
    # (optional) Cache size, default: 1000
    cache_size: 1000

Lookup file contains one key-value pair per line. Mapping must be in format :. All additional colons in key or value must be escaped with ''. If source-field matches lookup key, a target field is set to lookup value.

Example lookup file

Map source hostname to service as per hosts-lookuptable.txt. Use example yaml config block.

hosts-lookuptable.txt:

192.168.100.10:webserver
192.168.100.20:db-server
192.168.100.20\:22:ssh-server
