Timestamp

The Timestamp filter accepts a UNIX timestamp from metadata and observes the duration between that timestamp and now. Mostly useful in combination with other filters such as Capture to pull timestamp data from packets.

Filter name

quilkin.filters.timestamp.v1alpha1.Timestamp

Configuration Examples

#![allow(unused)]
fn main() {
let yaml = "
version: v1alpha1
filters:
  - name: quilkin.filters.capture.v1alpha1.Capture
    config:
      metadataKey: example.com/session_duration
      prefix:
        size: 3
        remove: false
  - name: quilkin.filters.timestamp.v1alpha1.Timestamp
    config:
        metadataKey: example.com/session_duration
clusters:
  - endpoints:
    - address: 127.0.0.1:26000
";
let config = quilkin::config::Config::from_reader(yaml.as_bytes()).unwrap();
}
