Monitoring and Logs

PaaS Cloud includes a monitoring stack based on VictoriaMetrics (metrics), Loki (logs), and Grafana (dashboards and alerting) for your tenant workloads and virtual machines.

Access the Monitoring Stack

1. Log into https://chloe.platform.cloud.e-infra.cz/.
2. Navigate to the Monitoring section in your tenant.
3. Click the Grafana link to open the dashboards.

Authentication is generally integrated with your tenant identity. If you see a login prompt, use your standard PaaS Cloud credentials.

Available Dashboards

Typical dashboards include:

• Cluster / Node Overview — CPU, memory, disk, and network utilization.
• Application Metrics — Request rates, latency, error rates for deployed services.
• Database Metrics — Connection counts, query performance, storage usage for managed databases.
• Virtual Machine Metrics — Guest OS metrics when the QEMU guest agent is running inside the VM.

Viewing Logs

• In Grafana, open the Explore view.
• Select the Loki logging data source.
• Filter by tenant, application name, pod, or VM to narrow down results.
• Use labels and queries to search for errors, patterns, or specific time ranges.

VM Guest Metrics

For advanced VM monitoring, the QEMU guest agent provides guest-level metrics. You can query these through virtctl guest-agent commands or view them in Grafana when the agent is installed inside the VM. See Using virtctl for details.

Alerts

• The platform may define common alert rules (e.g., high CPU, low disk space, pod restarts).
• You can view triggered alerts inside the Grafana alerting section or in the dashboard notifications panel.
• Contact the cloud team if you need custom alert rules for your tenant.

Exporting and Sharing

• You can export dashboard snapshots or panels as images.
• Share dashboard links with project members. Avoid sharing publicly unless the data is non-sensitive.
