Which 30 Node Exporter metrics matter for Prometheus monitoring. Skip the 200 noisy ones. Textfile collector trick included.

Self-host Grafana OnCall as a free PagerDuty alternative: escalation policies, Alertmanager webhooks, and phone alerts for your home lab (plus the 2026 catch).

Self-hosted Healthchecks.io for cron monitoring with dead-man-switch alerting, Docker setup, and backup integration. Never miss a silent failure again.

Prometheus pull metrics are great until they aren't. When batch jobs, NAT, and ephemeral containers break scraping, Pushgateway, PushProx, and alternatives explained.

Blackbox exporter Prometheus probes HTTP TCP DNS ICMP synthetic monitoring without paying for Pingdom or SaaS uptime tools

SigNoz killed install.sh and its bundled Compose files. Here's how to self-host it with Foundry, wire an app via OTLP, and set retention and alerts.

Error budgets work on a home lab too. What an SLI and SLO actually are, picking an availability target you can hit, 28-day windows, and burn-rate alerts.

Distributed tracing with Tempo and Grafana for self-hosted multi-service stacks. OpenTelemetry, sampling, exemplars, and when tracing actually matters at home scale.

Prometheus federation for multi-site home labs: hierarchical scraping, cross-cluster aggregation, federation vs remote_write, practical config.

TrueNAS Scale ditched Kubernetes for native Docker. Apps catalog vs raw Compose, when each wins, dataset snapshots, and why custom apps took so long.

Four file-sharing protocols compared for home labs: NFS speed, SMB compatibility, SSHFS convenience, WebDAV over HTTP, and which one to pick per use case.

Compare cold storage tiers: Backblaze B2, Storj decentralized cloud, and Scaleway Glacier. Pricing, egress, restore times, and which backup service wins.
