DESCRIPTION

This script assists in maintaining the indexes for logging clusters through routine deletion and optimization of indexes.

Use with cron:

22 4 * * * es-daily-index-maintenance.pl --local --all --delete-days=180 --replicas-age=90 --replicas-min=1

OPTIONS

close

Run the close hook

close-days

Integer, close indexes older than this number of days

delete

Run the delete hook

delete-days

Integer, delete indexes older than this number of days

optimize

Run the optimization hook

optimize-days

Integer, optimize indexes older than this number of days

replicas

Run the replicas hook.

replicas-age

The age at which we reach --replicas-min, default 60

replicas-min

The minimum number of replicas to allow replica aging to set. The default is 0

--replicas-min=1

replicas-max

The maximum number of replicas to allow replica aging to set. The default is 1

--replicas-max=2

skip-alias

Can be set more than once. Any indexes with an alias that matches this list is skipped from operations. This is a useful, lightweight mechanism to preserve indexes.

--skip-alias preserve --skip-alias pickle

In addition to user specified aliases, the aliases .hold and .do_not_erase will always be excluded.
