# elasticache-redis-cost

Command elasticache-redis-cost suggests AWS ElastiCache for Redis instance

types that can fit existing Redis instances.

    Usage of elasticache-redis-cost:

      -any-family

        	take into account all instance families, not only memory-optimized

      -any-generation

        	take into account old generation instance types

      -csv

        	print report in CVS instead of formatted text

      -html path

        	path to HTML file to save report; if empty, text report is printed to stdout

      -max-load int

        	source dataset must fit this percent maxmemory utilization of the target, [1,100] range (default 80)

      -redises path

        	path to file with Redis addresses, one per line (/dev/stdin to read from stdin)

      -region region

        	use prices for this AWS region (default "us-east-1")

      -reserved-memory-percent int

        	value of reserved-memory-percent ElastiCache parameter, [0,100] range (default 25)

    

    Please see AWS documentation regarding reserved-memory-percent if you decide to change it:

    > The percent of a node's memory reserved for nondata use. By default, the

    > Redis data footprint grows until it consumes all of the node's memory. If

    > this occurs, then node performance will likely suffer due to excessive

    > memory paging. By reserving memory, you can set aside some of the available

    > memory for non-Redis purposes to help reduce the amount of paging.

    

    > This parameter is specific to ElastiCache, and is not part of the standard

    > Redis distribution.
