[[examples]] == Examples === Delete _all_ indices with matching <> which are older than 30 days ----- curator --host 10.0.0.2 delete indices --older-than 30 --time-unit days \ --timestring '%Y.%m.%d' -----   In previous versions of Curator, you would have needed as many runs of the command-line as you had prefixes, no matter the matching pattern. Not so any more! With this example, _all_ indices with a pattern of `%Y.%m.%d` inside will be deleted. This is useful for managing both Logstash and Marvel indices with a single command, if you want the same retention period. NOTE: Kibana indices are omitted from deletion by default. === Alias a subset of indices ----- curator --host 10.0.0.2 alias --name lastmonth indices --newer-than 60 \ --older-than 30 --timestring '%Y.%m.%d' --time-unit days --prefix logstash -----   In this example, logstash indices older than 30 days--but newer than 60--are added to alias `lastmonth`. Please note that Curator does not create aliases. It can only add to them or remove from them. Let's take this example further, though. ----- curator --host 10.0.0.2 alias --name lastmonth --remove indices --older-than 60 \ --timestring '%Y.%m.%d' --time-unit days --prefix logstash curator --host 10.0.0.2 alias --name lastmonth indices --newer-than 60 \ --older-than 30 --timestring '%Y.%m.%d' --time-unit days --prefix logstash -----   The updated, 2 line example now _removes_ indices older than 60 days first, and then proceeds to make sure that everything between 30 and 60 days is in the alias. Note that Curator will not re-alias if the index is already in the alias. === Optimize only the specified indices ----- curator --host 10.0.0.2 optimize --max_num_segments 1 --delay 120 \ --index indexname1 --index indexname2 -----   This command will _only_ operate on the named indices, `indexname1` and `indexname2`. It will pause for `120` seconds after optimizing each index. === Show only indices with a timestring ----- curator --host 10.0.0.2 show indices --timestring '%Y.%m.%d' -----   While timestring may nearly always be seen alongside <>, <>, and <>, there may be cases when you just want to act on indices with a timestamp in the name. === Close all indices, excepting those matching patterns `do-not-touch` and `logstash-2015.03` ----- curator --host 10.0.0.2 close indices --exclude do-not-touch --exclude logstash-2015.03 -----   In this case, all indices saving those matching pattern `kibana`, or all Logstash indices for the month of March 2015 will be closed.
