### Correlation

Degree of dependency between consecutive packets. Tune it by using the `CORRELATION` environment variable.

The following YAML snippet illustrates the use of this environment variable:

[embedmd]:# (./static/manifests/pod-network-corruption/correlation.yaml yaml)
```yaml
apiVersion: litmuschaos.io/v1alpha1
kind: ChaosEngine
metadata:
name: engine-nginx
spec:
engineState: "active"
annotationCheck: "false"
appinfo:
appns: "default"
applabel: "app=nginx"
appkind: "deployment"
chaosServiceAccount: litmus-admin
experiments:
- name: pod-network-corruption
spec:
components:
env:
- name: CORRELATION
value: '100' #in percentage
- name: TOTAL_CHAOS_DURATION
value: '60'
```

### Destination IPs and destination hosts

Default IPs and hosts whose traffic is interrupted due to the network faults. Tune it by using the `DESTINATION_IPS` and `DESTINATION_HOSTS` environment variables, respectively.
