2. run command **logstash-plugin prepare-offline-pack logstash-filter-json\_encode**

```auto
Offline package created at: C:/Users/deepsing/Downloads/logstash-6.3.0/logstash-offline-plugins-6.3.0.zip

You can install it with this command `bin/logstash-plugin install file://C:/Users/deepsing/Downloads/logstash-6.3.0/logstash-offline-plugins-6.3.0.zip`

```

1. Uninstall the plugin the existing plugin **logstash-plugin uninstall logstash-filter-json\_encode**
2. Stop internet connectivity
3. Run this command to install plugin offline **logstash-plugin install file://C:/Users/deepsing/Downloads/logstash-6.3.0/logstash-offline-plugins-6.3.0.zip`**
