### 1. Tomcat server.xmlファイルにロギング関連設定を修正します。 <a href="#id-1" id="id-1"></a>

{% hint style="info" %}

```
# Change for PLURA log format

 <Valve className=”org.apache.catalina.valves.AccessLogValve” directory=”/var/log/plura”
 rotatable=”false”
 renameOnRotate=”false”
 prefix=”weblog” suffix=”.log”
 pattern=”{“Remote-addr”: “%a”, “X-forwarded-for”: “%{X-Forwarded-For}i”, “Request-date”: “%{dd/MM/yyyy:HH:mm:ss.SSS}t +0900”, “Method”: “%m”, “Request”: “%r”, “Host”: “%A”, “Uri”: “%U”, “Cookie”: “%{Cookie}i”, “Referer”: “%{Referer}i”, “User-Agent”: “%{User-Agent}i”, “Status”: “%s”, “Resp-Content-Length”: “%b”}” />

 2localhost.org.apache.juli.FileHandler.suffix = log
```

{% endhint %}

### 3. Tomcatリブート <a href="#id-3" id="id-3"></a>
