有的时候咱们在使用ES时,因为资源有限或业务需求,咱们只想保存最近一段时间的数据,因此有以下脚本能够定时删除数据curl
delete_es_by_day.shpost
#!/bin/sh # example: sh delete_es_by_day.sh logstash-kettle-log logsdate 30 index_name=$1 daycolumn=$2 savedays=$3 format_day=$4 if [ ! -n "$savedays" ]; then echo "the args is not right,please input again...." exit 1 fi if [ ! -n "$format_day" ]; then format_day='%Y%m%d' fi sevendayago=`date -d "-${savedays} day " +${format_day}` curl -XDELETE "10.130.3.102:9200/${index_name}/_query?pretty" -d " { "query": { "filtered": { "filter": { "bool": { "must": { "range": { "${daycolumn}": { "from": null, "to": ${sevendayago}, "include_lower": true, "include_upper": true } } } } } } } }" echo "ok"
