VictoriaMetrics (VM for short) is a time-series database compatible with the Prometheus ecosystem. It uses fewer resources than Prometheus and comes in both single-node and cluster editions. The single-node edition can directly replace Prometheus storage; the cluster edition splits reads, writes, and storage across vmstorage / vminsert / vmselect, giving it stronger horizontal scaling.

1. Background Node Exporter is a common component in the Prometheus ecosystem for collecting host metrics, but by default it does not provide access authentication. This article describes how to add basic authentication to Node Exporter in a Kubernetes environment to improve security. 2. Configuring Credentials for Node Exporter 2.1 Generating an Encrypted Password Use the htpasswd tool to generate an encrypted password:

1. What smokeping-prober Is smokeping-prober is a tool for probing network quality. It probes network quality by sending ICMP requests to target nodes. 2. Deploying smokeping-prober 2.1 Generating the smokeping-prober.yaml Configuration File 1 2 3 4 5 6 7 8 9 10 11 cat > smokeping_prober.yaml <<EOF --- targets: - hosts: - 1.

1. Skipping Certificate Verification Prevents Scraping If you can skip TLS authentication when scraping metrics, that is the easiest path. The Prometheus ConfigMap configuration looks like this: 1 2 3 4 5 6 7 8 9 - job_name: etcd metrics_path: /metrics scheme: https tls_config: insecure_skip_verify: true static_configs: - targets: ["1.1.1.1:2379"] - targets: ["2.
