 ====== elasticsearch ======
-==== Ant中將logging設定改為rolling file ====
+===== 透過ant將預設logging.yml設定改為rolling file =====
+目標是要將
+<code>
+  file:
+    type: dailyRollingFile
+    file: ${path.logs}/${cluster.name}.log
+    datePattern: "'.'yyyy-MM-dd"
+    layout:
+      type: pattern
+      conversionPattern: "[%d{ISO8601}][%-5p][%-25c] %.10000m%n"
+</code>
+修改為
+<code>
+  file:
+    type: rollingFile
+    file: ${path.logs}/${cluster.name}.log
+    maxFileSize: 8000KB
+    maxBackupIndex: 10
+    layout:
+      type: pattern
+      conversionPattern: "[%d{ISO8601}][%-5p][%-25c] %.10000m%n"
+</code>
+ant內容如下:
 <code xml>
 <replaceregexp file="config/logging.yml" match="type: dailyRollingFile" replace="type: rollingFile${line.separator}    maxFileSize: 8000KB${line.separator}    maxBackupIndex: 10" flags="g"/>
 <replaceregexp file="config/logging.yml" match="[ \t]*datePattern: .*[\r\n]*" replace="" flags="g"/>
 </code>
-==== Reference ====
+===== 打開search與index的debug =====
+在使用預設的loggin.yml情況下，新增以下內容到elasticsearch.yml:
+<code>
+index.search.slowlog.threshold.query.debug: 0s
+index.search.slowlog.threshold.fetch.debug: 0s
+index.indexing.slowlog.threshold.index.debug: 0s
+</code>
+接著使用rest client去操作elasticsearch:
+<code>
+curl http://127.0.0.1:9200/_search
+</code>
+最後就可以查看index_search_slowlog.log的內容；裡面要有資料才會有log產生。
