A practical deployment has four parts: configure DNStap on each DNS server, secure and configure the collector’s listener, define an output and routing policy in config.yml, then validate the flow from DNS query to stored event.
How the deployment fits together
DNS-collector uses pipeline components for collection, optional transformation, routing, and output. A collector needs a routing policy that forwards events to a logger. For a centralized design, multiple DNS servers stream DNStap over TCP/TLS to one collector; the project describes this as its centralized deployment pattern: Centralized Deployment. The pipeline guide explains that components are configured in pipeline stanzas: Pipeline Routing.
The project’s quick start listens on TCP port 6000 and prints events to standard output. That is useful as a smoke test, not a production destination or a recommendation to expose an all-interface listener without network controls. See the project repository for the quick-start example.
Choose an installation method and destination
The official installation guide documents precompiled binaries for Linux, macOS, and Windows, Docker containers, and building from source. Its Docker example mounts a custom configuration at /etc/dnscollector/config.yml. Check the installation instructions and current release for platform-specific details, since releases and instructions can change.

Choose a destination that fits your existing logging stack, event format, operational ownership, and the project’s stated support maturity. The logger catalog currently labels Loki and Elasticsearch production-ready, while ClickHouse and InfluxDB are labeled beta. Those are the project’s own labels, not an independent reliability assessment; check the logger catalog for current status.
| Destination | What the project documents | Useful fit questions |
|---|---|---|
| Loki | HTTP push logger with text, JSON, or flat JSON output; batching, retries, TLS, and authentication options. The project catalog labels it production-ready. Loki logger; logger catalog. | Do you already operate Grafana and Loki? How will you design labels and queries, secure the endpoint, and tune batching? |
| Elasticsearch | Direct logger integration; project catalog status is production-ready. Logger catalog. | Does the existing cluster, schema, indexing and retention approach, and query workflow suit DNS events? |
| Syslog | Catalog lists RFC3164/RFC5424 formats and TLS. Logger catalog. | Can the existing SIEM or log receiver accept the chosen message format and transport settings? |
| Kafka | A producer logger for publishing events to topics. Logger catalog. | Do downstream consumers need a brokered event stream, and how will delivery and retention be managed? |
| ClickHouse or InfluxDB | The project catalog labels both beta. Logger catalog. | Is beta status acceptable for this deployment, and do the database’s query and operations model fit the use case? |
Configure DNStap input on the DNS servers and collector
Enable DNStap logging on each DNS server using that server’s own documentation, then point its stream at the collector. DNS-collector accepts TCP or Unix DNStap streams and supports listener TLS. The documented listener settings include bind IP, port, TLS enablement, minimum TLS version, certificate file, and private key file; see the DNStap collector options.

- MANUAL NETWORK SETUP REQUIRED: Configuration via web interface (static IP or DHCP) using LPR queue “LP1"; Not plug-and-play, requires intermediate network knowledge for installation; Access our online FAQs for additional helpful tips and instructions
- USB PRINTER COMPATIBILITY: Works with most USB 2.0 printers using standard drivers; Not compatible with USB hubs, multi-function printers with proprietary drivers, or printers requiring full bi-directional communication
- COMPATIBILITY: The USB to Ethernet print server is USB 2.0 compliant and works with macOS and Windows; It also supports LPR network printing and Bonjour Print Services for broad compatibility; Included software is compatible with Windows only
- PRINT FROM ANYWHERE: Print from any computer connected to the Ethernet; This print server doesn’t require a wired connection to a computer, however it must be connected to your networking device (eg. router or switch) with the included RJ45 network cable
The quick-start example binds to 0.0.0.0:6000, meaning all IPv4 interfaces. In production, choose a deliberate bind address and restrict reachability to authorized DNS servers. Use TLS when the stream crosses a network that requires protection, and configure the listener’s certificates and minimum TLS version to match your security policy. The sample bind is not a firewall policy.
Define the pipeline and validate its configuration
The project’s YAML configuration file is named config.yml. A pipeline stanza defines an input collector or output logger, optional transformations, and a routing policy. This example follows the documented collector-to-Loki shape; adapt names, addresses, TLS, and output settings to your deployment.

- Save the adapted YAML as

./dnscollector -config config.yml -test-configbefore rolling out the service. Correct any reported configuration errors before proceeding. - Start the collector using the deployment method you selected, then check its logs and the destination’s own query interface as you test the stream.
Decide what DNS detail to retain
DNS telemetry can reveal queried names and client context, so decide what investigators need before collecting and retaining it. DNS-collector’s privacy transformer can mask IP host bits, hash query or response IP addresses, and keep only the second-level domain. Other transformations can normalize names, filter traffic, or enrich events; see the transformer documentation and the user-privacy transformer options.

Secure and operate the collection path
For DNStap input, use valid certificates and keys when enabling TLS and keep the listener reachable only by intended senders. For Loki output, the logger documents CA, certificate, key, minimum TLS version, Basic Auth, and password-file options, as well as retries and batch/flush controls. Protect configuration and key files, keep secrets out of readable examples, and do not disable certificate verification in production without a specific, accepted reason. Consult the DNStap options and Loki logger options.
The project documentation does not establish a supported throughput-to-resource sizing matrix or a current benchmark for a particular workload. There is no defensible universal CPU, memory, network, or storage recommendation here. Size the collector and destination with representative event-rate tests, required retention and buffering, and the destination’s ingestion limits.
