### Is there an existing issue for this? - [x] I have searched the existing issues ### Current Behavior When using GreptimeDB as the time-series database in HertzBeat 1.8.0, the metrics labels of monitoring tasks are not written into the database. However, when switching to VictoriaMetrics, the labels are written correctly. <img width="3002" height="1632" alt="Image" src="https://github.com/user-attachments/assets/289019a8-e9a5-428d-b267-4ffbfe60a1ca"; /> **VictoriaMetrics (labels are present)** <img width="3024" height="1650" alt="Image" src="https://github.com/user-attachments/assets/e8b3a17a-0c3c-4203-b4b3-fa4a9b11020b"; /> → Custom labels are correctly stored and can be queried. --- **GreptimeDB (labels are missing)** <img width="3024" height="1654" alt="Image" src="https://github.com/user-attachments/assets/40c84387-ab4a-4f93-9f49-5b982c6cbc25"; /> → Custom labels are NOT written into the database. ### Expected Behavior Metrics labels should be written consistently regardless of the selected time-series database backend. ### Steps To Reproduce 1. Deploy HertzBeat 1.8.0 2. Configure GreptimeDB as the storage backend 3. Create a monitoring task with labels 4. Check stored metrics in GreptimeDB → labels missing 5. Switch to VictoriaMetrics 6. Check metrics again → labels exist ### Environment ```markdown HertzBeat version(s): v1.8.0 Time-series DB: GreptimeDB (issue occurs) VictoriaMetrics (works as expected) ``` ### Debug logs _No response_ ### Anything else? _No response_ -- This is an automated message from the Apache Git Service.
