What is Prometheus Node Exporter?

The prometheus-node-exporter image runs the Node Exporter, a Prometheus exporter that exposes a wide range of hardware and OS metrics from a Linux host — CPU, memory, disk I/O, filesystems, network, load averages — over a simple HTTP endpoint at `/metrics`. It's the canonical way to monitor cluster nodes, deployed as a DaemonSet on every node.

What is Echo's Prometheus Node Exporter image?

Echo's prometheus-node-exporter image is a hardened build of node_exporter on a minimal base. Echo images are designed to be a drop-in replacement: change the FROM line in your Dockerfile and CVEs go to zero without breaking your app. Every image is tested across clouds, image use cases, and deployment targets. Echo ships every image in two variants: a distroless variant optimized for runtime use, and a default variant that includes essential build tools, package managers, and shells. Because node_exporter runs as a DaemonSet on every node, the CVE multiplier is significant - every base-image CVE multiplies by your cluster size in compliance reports.

What is the difference between Echo's Prometheus Node Exporter image and the public Prometheus Node Exporter image?

Public node_exporter images often add OS tooling that the exporter doesn't actually use, contributing CVEs that scan reports flag on every node. Echo's build is reduced to what node_exporter needs, dropping the per-node CVE count to zero. Echo commits to a 7-day SLA for critical and high severity vulnerabilities, and 10 days for medium, low, and unknown - with vulnerabilities triaged within 24 hours. Echo images are recognized by all major scanners and mirrored to all major registries, so they fit into existing pipelines without changing your registry, scanner, or runtime tooling.

FAQ

Can I replace my prometheus-node-exporter image with Echo's prometheus-node-exporter image?

Yes. Echo's prometheus-node-exporter image is a drop-in replacement. Update the FROM line in your Dockerfile (or the image reference in your manifests) and your application keeps working - the CVEs disappear, the behavior doesn't.

Is Echo's prometheus-node-exporter image FIPS-validated?

Yes. Echo's FIPS-validated images use cryptographic modules with an active FIPS 140-3 CMVP certificate, making them fit for federal use - unlike FIPS-compliant images that haven't been validated.

What is Echo's vulnerability management SLA on the prometheus-node-exporter image?

Echo commits to a 7-day SLA for critical and high severity vulnerabilities, and 10 days for medium, low, and unknown - with vulnerabilities triaged within 24 hours. Patches are mirrored automatically into your private registry so you're always running a clean version.

Is Echo's prometheus-node-exporter image distroless?

Echo ships every image in two variants: a distroless variant optimized for runtime use, and a default variant that includes essential build tools, package managers, and shells.

How does Echo achieve such a drastic CVE reduction in prometheus-node-exporter?

Echo prometheus-node-exporter is built from source with only the absolute essentials needed to run the workload, which significantly shrinks the attack surface. Echo also patches aggressively over time, with backports available so you can stay on the version that works for you without forcing a functional change for the sake of security.

Will Echo's prometheus-node-exporter image help us achieve FedRAMP?

Yes. The hard parts of FedRAMP - managing vulnerabilities, applying fixes, and using FIPS-validated cryptography - are baked into Echo images, including STIG-hardened configuration and ConMon/POA&M-ready reporting.
