Alfred Version: 0.0.3
```

Alfred was built as a tool to handle maintenance work on ElasticSearch.
Alfred will delete, flush cache, optimize, close/open, enable/disable bloom filter, as well as put settings on indexes.
Alfred can do any of these actions based on either time or size parameters.

Examples:
```
java -jar alfred.jar -e48 -i"cron_*" -d
```
Delete any indexes starting with "cron_" that are older that 48 hours
```
java -jar alfred.jar -e24 -i"cron_*" -S'{"index.routing.allocation.require.tag":"historical"}'
```
Set routing to require historical tag on any indexes starting with "cron_" that are older that 24 hours
```
java -jar alfred.jar -e24 -i"cron_*" -b -o
```
Disable boom filter and optimize any indexes starting with "cron_" that are older that 24 hours
```
java -jar alfred.jar -ssize -E"1 GB" -d
```
Find all indxes, group by prefix, and delete indexes over a limit of 1 GB. Using the size style with an expire size does not check space based on a single index but rather the indexes adding up over time. Such as the following...
```
java -jar alfred.jar -i"cron_*" -d -ssize -E"500 GB"
GENERAL: cron_2014_04_02_08 is 469.9 GiB bytes before the cuttoff.
GENERAL: cron_2014_04_02_07 is 436.5 GiB bytes before the cuttoff.
GENERAL: cron_2014_04_02_06 is 404.0 GiB bytes before the cuttoff.
GENERAL: cron_2014_04_02_05 is 372.1 GiB bytes before the cuttoff.
GENERAL: cron_2014_04_02_04 is 341.2 GiB bytes before the cuttoff.
GENERAL: cron_2014_04_02_03 is 310.1 GiB bytes before the cuttoff.
GENERAL: cron_2014_04_02_02 is 276.8 GiB bytes before the cuttoff.
GENERAL: cron_2014_04_02_01 is 240.7 GiB bytes before the cuttoff.
GENERAL: cron_2014_04_02_00 is 202.2 GiB bytes before the cuttoff.
GENERAL: cron_2014_04_01_23 is 158.2 GiB bytes before the cuttoff.
GENERAL: cron_2014_04_01_22 is 110.6 GiB bytes before the cuttoff.
GENERAL: cron_2014_04_01_21 is 58.6 GiB bytes before the cuttoff.
GENERAL: cron_2014_04_01_20 is 3.1 GiB bytes before the cuttoff.
GENERAL: Index cron_2014_04_01_19 would have been deleted.
GENERAL: Index cron_2014_04_01_18 would have been deleted.
GENERAL: Index cron_2014_04_01_17 would have been deleted.
GENERAL: Index cron_2014_04_01_16 would have been deleted.
GENERAL: Index cron_2014_04_01_15 would have been deleted.
GENERAL: Index cron_2014_04_01_14 would have been deleted.
GENERAL: Index cron_2014_04_01_13 would have been deleted.
GENERAL: Index cron_2014_04_01_12 would have been deleted.
GENERAL: Index cron_2014_04_01_11 would have been deleted.
GENERAL: Index cron_2014_04_01_10 would have been deleted.
GENERAL: Index cron_2014_04_01_09 would have been deleted.
GENERAL: Index cron_2014_04_01_08 would have been deleted.
GENERAL: Index cron_2014_03_29_08 would have been deleted.

If you are using daily indexes, such as the marvel indexes, you could use the following examples to manage them
```
java -jar alfred.jar -i".marvel-*" -d -ssize -E"500 GB"
```
Keep the past 500 GB worth of marvel indices
```
java -jar alfred.jar -i".marvel-*" -d -T"day" -e7
```
Delete marvel indices older than 7 days old
```
java -jar alfred.jar -i".marvel-*" -b -o -T"day" --max_num_segments=4 -e1
```
Disable bloom filter and optimize marvel indices with max_num_segments=4 over 1 day old
```
java -jar alfred.jar -e48 -i"*" -x"marvel,kibana" -d
```
Delete all indexes excluding any that contain the keywords "marvel" or "kibana" that are older that 48 hours

The following regular expression is used to split indexes into appropriate variables...
```
^((?<Name>[a-zA-Z0-9\\.\\-_]+)(?<PrefixSeparator>(_|-)+)(?<Year>[0-9]{4})(?<Separator>(\\.|_|-))(?<Month>[0-9]{2})(\\.|_|-)(?<Day>[0-9]{2})(\\.|_|-)?(?<Hour>[0-9]{2})?)$
```
As long as your indexes following the pattern of this regular expression, Alfred will be glad to manage your indices.
