Customize RPA logrotate

The section describes how to tweak the log rotation on RPA Server. This feature is needed to free disk space and improve security.

Go to ${rpa_installation_folder}\rpa-grid (by default it is C:\RPA\rpa-grid).
Change the following values in logback-hub.xml and in all needed logback-nodeX.xml files:
- To change the max size of RPA log, add the <maxFileSize> tag inside the <timeBasedFileNamingAndTriggeringPolicy> tag, and set value of this tag (1024KB, 100MB, 1GB etc.):
```
<timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
    <maxFileSize>100MB</maxFileSize>
</timeBasedFileNamingAndTriggeringPolicy>
```
- To change max days of history of logs, add the <maxHistory> tag inside the <rollingPolicy> tag, and set value of this tag as a number (10, 30, 60, etc.):
```
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
    <maxHistory>30</maxHistory>
</rollingPolicy>
```

<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <fileNamePattern>${LOG_DIR}/${LOG_FILE_NAME}-%d{yyyy-MM-dd}.%i.log</fileNamePattern>
        <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
            <!-- or whenever the file size reaches 100MB -->
            <maxFileSize>100MB</maxFileSize>
        </timeBasedFileNamingAndTriggeringPolicy>
        <!-- keep 30 days' worth of history -->
        <maxHistory>30</maxHistory>
    </rollingPolicy>
    <encoder>
        <charset>UTF-8</charset>
        <pattern>%date{ISO8601} %-5level [%thread] %class.%M[:%L] - %msg%n</pattern>
    </encoder>
</appender>

Customize RPA logs location

RPA Nginx

Open nginx.conf located in <RPA_ROOT>/nginx/conf directory and add the following lines before server section:
```
access_log d:/RPA/nginx/access.log;
error_log d:/RPA/nginx/error.log;


server {
...
```
Make sure that target directory exists before restarting nginx.

tip

If rotation scripts are used, update rotate_nginx_logs.bat script.

RPA grid

Open logback-*.xml located in the <RPA_ROOT>/rpa-grid directory and edit the LOG_DIR property:

<property name="LOG_DIR" value="d:/RPA/logs-grid"/>

Required files:

logback-hub.xml
logback-node0.xml
logback-node1.xml

Optional files depending on the number of configured RPA nodes:

logback-nodeX.xml
