DESCRIPTION

This script allows you to change index settings on indexes whose name matches the specified pattern.

Usage:

$ es-apply-settings.pl --local --pattern logstash-*
> { "index.routing.allocation.exclude.ip": "192.168.10.120" }

Or specify a file containing the settings

$ es-apply-settings.pl --local --pattern logstash-* settings.json

OPTIONS

help

Print this message and exit

manual

Print this message and exit

close

IMPORTANT: Settings are not dynamic, and the index needs to closed to have the settings applied. If this is set, the index will be re-opened before moving to the next index.

older

When this option is used along with the --days option the the setting will only be applied to indexs that are older than the days specified.

es-apply-settings.pl --older --days 30 --pattern logstash-*

skip-alias

Protected aliases, which if present will cause the application of settings to be skipped for a particular index. The aliases .hold and .do_not_erase will always be skipped.

no-skip

Apply settings to all matching indexes, regardless of the protected aliases.

no-diff

During a normal run, the settings you're requesting will be checked against the indices and only indices with settings out of line with the desired settings will be applied. If for some reason you want to apply settings regardless of the current state, using --no-diff will disable the check and apply the settings to every index in scope.
