GitLab log files and forwarding to a SIEM
Which GitLab logs matter for operations and security, shipping structured JSON logs to Elasticsearch, OpenSearch or Splunk, and handling stdout logs on the Helm chart.
GitLab monitoring and maintenance
Day-two operation of self-managed GitLab: logs, health checks, Prometheus metrics, maintenance mode and collecting data for support.
GitLab health check endpoints for load balancers and Kubernetes
Using /-/readiness and /-/liveness correctly in load balancers and probes, IP allowlisting for monitoring hosts and why /health_check should not drive autoscaling.
GitLab Maintenance Mode
Putting GitLab into read-only Maintenance Mode for upgrades, migrations and Geo failover: what users can still do, background jobs and the Premium requirement.
Monitoring self-managed GitLab with Prometheus
Scraping GitLab's bundled exporters into Prometheus and Grafana, the metrics worth alerting on and monitoring Gitaly, PostgreSQL and Redis tiers separately.
Collecting GitLab logs and diagnostics for support
Preparing a support case for self-managed GitLab: gitlab-ctl tail captures, the main log locations by component and what to collect before escalating to GitLab or a partner.
