Question 1

How do I set up Slack alerts in kwatch?

Accepted Answer

Configure the Slack webhook URL or bot token in the alert.slack section of config.yaml. For webhook mode, use the webhook parameter; for bot token, provide the token and channel, as specified in the Slack configuration table.

Question 2

kwatch vs Prometheus: which is better for Kubernetes monitoring?

Accepted Answer

kwatch is focused on real-time crash detection and immediate multi-channel alerts, while Prometheus offers comprehensive metrics collection, storage, and querying. Use kwatch for simple alerting; Prometheus for full observability with tools like Grafana.

Question 3

Can kwatch ignore crashes from specific pods?

Accepted Answer

Yes, use the ignorePodNames parameter with regex patterns in the general configuration to exclude certain pods from monitoring. This allows fine-grained control over which events trigger alerts.

Question 4

How to monitor PVC usage with kwatch?

Accepted Answer

Enable pvcMonitor.enabled in the config and set the threshold percentage. By default, it checks every 15 minutes and alerts if usage exceeds 80%, as described in the PVC monitor section.

Question 5

Does kwatch support alert escalation to multiple channels?

Accepted Answer

No, kwatch sends alerts to all configured channels simultaneously but lacks built-in escalation policies. For escalation, you need to rely on external services like PagerDuty or custom scripting.

Question 6

How to deploy kwatch in a custom namespace?

Accepted Answer

Use the Helm install command with the --namespace flag, e.g., --namespace monitoring, or modify the deploy.yaml file to specify the desired namespace before applying with kubectl.
