+# 概要
+
+在[SLS对接Kibana](https://help.aliyun.com/zh/sls/user-guide/use-kibana-to-access-the-elasticsearch-compatible-api-of-log-service) 方案中，会自动创建Index Pattern。可能一开始没有设置好logstore过滤条件，导致创建了一些不需要的logstore pattern，这时候 可以通过脚本来批量删除一些不需要的Index Pattern
+
+
+# 操作步骤
+
+## List出需要删除的Index Pattern
+
+准备好 kibana_config.json，然后使用  [ptn_list.py](ptn_list.py.md){target="_blank"} 来list Index Pattern
+```
+{
+    "url" : "http://xxx:5601",
+    "user" : "elastic",
+    "password" : "",
+    "space" :  "default"
+}
+```
+执行
+```
+➜  python ptn_list.py kibana_config.json > /tmp/ptnlist.txt
+```
+
+/tmp/ptnlist.txt可能是长这样的
+
+```
+54c0d6c0-b83b-11ef-88c6-15adf26175c7	etl-dev.batch_test52

+538ceaa0-b83b-11ef-88c6-15adf26175c7	etl-dev.batch_test50
+```
+
+编辑这个/tmp/ptnlist.txt文件，只留下需要删除的index pattern 的行
+
+## 执行Index Pattern删除
+
+**注意，Index Pattern删除后对应的Dashboard等都会无法使用，请确保这些Index Pattern是没有用的。**
+
+使用  [ptn_delete.py](ptn_delete.py.md){target="_blank"} 删除 Index Pattern
+
+
+```
+
+➜  cat /tmp/ptnlist.txt # 再看一眼 /tmp/ptnlist.txt，确认都是要删除的Index Pattern
+
+# 执行删除
