# Changing the Maximum Size of a Log File

By default, nnl.log can grow to 10 MB and nnlgateway.log to 1 MB before rolling over. To modify:

1. If you are configuring nnl.log, search log4j2-nnl.xml for the RollingFile element pertaining to it. Otherwise, skip this step.

```plaintext
<RollingFile fileName="${sys:catalina.base}/logs/nnl.log"
```

1. To change the maximum size of a log file, find the following string in this section.

```plaintext
<SizeBasedTriggeringPolicy
```

Change the size parameter to what you want.

```plaintext
<SizeBasedTriggeringPolicy size="9 MB"/>
```
