52-86: Consider adding time-based partitioning hintThe log query could benefit from time-based partitioning hints to improve performance, especially when dealing with large log volumes. Consider adding a comment about the expected query performance characteristics.
Add a comment above the query explaining the performance implications and any partitioning strategies:
-- Note: This query assumes time-based partitioning on the _gt_logs table -- for optimal performance when querying recent logscharts/greptimedb-cluster/README.md (1)
198-203: LGTM! Grafana datasource configuration looks good.The datasource configuration changes improve clarity through simplified naming and add the new information_schema datasource. Consider adding a comment to document the purpose of the information_schema datasource for better maintainability.
Add a comment above the datasources section explaining the purpose of each datasource, especially the new information_schema datasource. For example:
grafana.datasources | object | `{"datasources.yaml":{"datasources":[ +# metrics: Used for collecting and visualizing system metrics via Prometheus +# logs: Used for querying and analyzing system logs +# information_schema: Used for querying database metadata and system information {"access":"proxy","isDefault":true,"name":"metrics","type":"prometheus",

Line range hint 1-167: Overall dashboard configuration looks good
The dashboard configuration follows good practices:
- Proper use of template variables
- Effective time filtering with
$__timeFilter - Reasonable query limits (1000-3000)
- Good search functionality using pattern matching
87-88: Verify the new datasource configuration in Grafana
The datasource has been renamed from "greptimedb-logs" to "logs" with a new ID. Please ensure that this datasource ID matches the configuration in your Grafana instance.

87-89: Verify datasource ID consistency across configurations
The datasource has been renamed from "greptimedb-cluster-logs" to "logs" with a new ID. Ensure this ID matches the one configured in Grafana datasources.
✅ Verification successful
Datasource ID consistency verified
The new datasource ID "P98F38F12DB221A8C" is consistently used in the relevant dashboard configurations, and the old datasource references are no longer present.
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Check if the new datasource ID is consistently used across configurations
# Expected: The new datasource ID should be referenced in datasource configurations
# Search for the old datasource name or ID
rg -l "greptimedb-cluster-logs|ddxce12e8bl6oe" --type json
# Search for the new datasource ID
rg -l "P98F38F12DB221A8C" --type json

5-5: LGTM! Version bump looks good.
The version update from 0.2.29 to 0.2.30 is consistent with semantic versioning.

973-979: LGTM! Metrics datasource configuration looks good.
The metrics datasource has been renamed from greptimedb-metrics to metrics for better clarity. The configuration is properly set up to query metrics via the Prometheus API endpoint.
980-986: LGTM! Logs datasource configuration looks good.
The logs datasource has been renamed from greptimedb-logs to logs for better clarity. The configuration is properly set up to query logs and slow queries via MySQL protocol.
987-993: Verify the information_schema datasource access.
The new information_schema datasource is properly configured to query the information schema database via MySQL protocol. However, ensure that:
- The frontend service exposes the information_schema database
- The necessary permissions are granted to access this database
