Spam filter support in Infrastructure as Code

Spam filters in Dash0 let you drop unwanted logs, spans, and metrics before they reach storage by matching on structured attribute conditions. You can now manage spam filters as code using the Dash0 CLI, Terraform provider, and Kubernetes operator, so your data-hygiene rules live right alongside the rest of your infrastructure.

How it works

Every spam filter is expressed as a YAML document with kind: Dash0SpamFilter. The Dash0 CLI, Terraform provider and Kubernetes operator all accept the same YAML document that you can download from the Dataset configurations:

Dash0 CLI

The spam-filters command is currently experimental and requires the --experimental (or -X) flag:

sh
spams-filters.sh
1234567891011121314
# Create a spam filter from a YAML file
dash0 spam-filters create -X --dataset default -f drop-health-checks.yaml
# List all spam filters in a dataset
dash0 spam-filters list -X --dataset default
# Get a single spam filter as YAML
dash0 spam-filters get -X --dataset default <id>
# Update an existing spam filter
dash0 spam-filters update -X --dataset default <id> -f drop-health-checks.yaml
# Delete a spam filter
dash0 spam-filters delete -X --dataset default <id>

Terraform provider

spam-filters.tf
1234
resource "dash0_spam_filter" "drop_health_checks" {
dataset = "default"
spam_filter_yaml = file("${path.module}/filters/drop-health-checks.yaml")
}

Kubernetes operator

yaml
spam-filter.yaml
1234567891011121314
apiVersion: operator.dash0.com/v1alpha1
kind: Dash0SpamFilter
metadata:
name: drop-health-checks
namespace: monitoring
spec:
contexts:
- log
filter:
- key: "k8s.namespace.name"
value:
stringValue:
operator: "equals"
comparisonValue: "kube-system"

One more thing…

We have reworked the Spam Filters UI under Datasets so that you can name your spam filters (which of course works also via Infrastructure as Code), and download both the SpamFilters CRD to use with the Terraform provider for Dash0, the CLI and the Kubernetes operator.

OK, I meant two more things

With any luck, there will be another much requested capability about spam filters going live in the new few weeks. Keep your eyes peeled ;-)
