Filter Plugins
Filter plugins process the data. They can parse, enrich, or transform it. Here’s an example of using the grok filter to parse log data:
filter {
grok {
match => { "message" => "%{COMMONAPACHELOG}" }
}
}
The grok filter uses predefined patterns to parse log data. In this case, it’s using the COMMONAPACHELOG pattern to parse Apache access logs.
