logstash - Remove unnecessary fields in ElasticSearch -

-

we populating elasticsearch via logstash. thing see unnecessary fields had remove example:

@version file geoip host message offset tags

is possible defining/extending dynamic template? if yes, how? if no, can via logstash configuration?

your appreciated.

you can remove fields using logstash filter - when filter succeeds, remove field.

it makes sense me use mutate:

filter {     mutate {         remove_field => [ "file" ]     } }

that said, of these fields incredibly useful , should not removed.

this function st3 = (x, y) -> console.log "#{x?}, #{y?}" if [x?, y?] [true, true] # <- line 'good' 'bad' this output true, true bad i want able tuple comparison in python. in python, if can written as if (x, y) == (true, false): return 'good' the coffescript if loop translated javascript such if ([x != null, y != null] === [true, true]) { 'good'; } that's why not evaluated true. is there alternative way express in coffeescript? if want check see if of arguments not none , this: def check_all(*args): return all(arg not none arg in args) if wanted check if they're true (like literally true) use def check_all(*args): return all(arg true arg in args) if wanted take in list (instead of variable number of parameters, remove asterisk.
