Poem

Oh, what a hop, a joyful leap,
New dashboards bloom while metrics peep.
A service monitor now aglow,
Guiding data where it needs to go.
With a twitch of whiskers and ASCII art so neat,
This rabbit cheers for changes sweet!

2-3:

❓ Verification inconclusive

Service monitoring properly enabled for ClickHouse operator.

The addition of the serviceMonitor configuration with enabled: true will allow Prometheus to automatically discover and scrape metrics from the ClickHouse operator, enhancing observability.

---

🏁 Script executed:

#!/bin/bash
# Verify that the Prometheus Operator CRDs are installed in the cluster
# This is necessary for ServiceMonitor resources to work

# Check if ServiceMonitor CRD exists
kubectl get crd servicemonitors.monitoring.coreos.com > /dev/null 2>&1
if [ $? -eq 0 ]; then
  echo "✅ ServiceMonitor CRD exists, configuration will work as expected"
else
  echo "❌ ServiceMonitor CRD not found - monitoring may not work until Prometheus Operator is installed"
fi

# Check if the operator itself exposes metrics (should have a metrics port/endpoint)
echo "Checking if altinity-clickhouse-operator deployment exposes metrics..."
kubectl get deployments -A | grep altinity-clickhouse-operator

Attention Required - Verification Inconclusive

The serviceMonitor configuration in packages/system/clickhouse-operator/values.yaml is correctly set to enable Prometheus monitoring. However, the verification script did not yield conclusive results due to the absence of kubectl (as indicated by the "command not found" error). This makes it difficult to confirm if the Prometheus Operator CRDs (specifically the ServiceMonitor CRD) are installed and if the altinity-clickhouse-operator deployment properly exposes metrics.

• Action Required: Please run manual verification or re-run the verification script in an environment where kubectl is available. Confirm that the ServiceMonitor CRD exists and that the operator exposes the required metrics.

✅ Verification successful

ClickHouse operator dashboard successfully added.

Adding the ClickHouse Altinity operator dashboard complements the enabling of service monitoring in the operator configuration. This provides a comprehensive monitoring solution for the ClickHouse infrastructure.

---

🏁 Script executed:

#!/bin/bash
# Verify the dashboard exists in the repository or monitoring system

# Check if the dashboard file exists in standard locations
echo "Checking for dashboard file in common locations..."
fd -g "*altinity-clickhouse-operator*.json" || echo "Dashboard file not found in standard locations"

# Check if there are any references to importing this dashboard in the codebase
echo "Checking for references to importing this dashboard..."
rg -i "altinity-clickhouse-operator-dashboard"

Verified: ClickHouse Operator Dashboard Addition Is Correct

The ClickHouse Altinity operator dashboard has been successfully added. Verification confirms that:

• The dashboard file exists at dashboards/clickhouse/altinity-clickhouse-operator-dashboard.json.
• The dashboard is correctly referenced in packages/extra/monitoring/dashboards.list.

All changes are as expected.

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
