The Table Metrics page shows real-time monitoring data for a selected table, organized across four sections: core health, the Query Result Searcher (QRS) worker, the Searcher worker, and data updates.
To open the page, go to the instance details page and choose Metric Monitoring > Table Metrics in the left-side navigation pane. Select a table from the drop-down list and set a time range to scope the data.
Metrics
Core metrics
The Core section shows overall table health.
| Metric | Description |
|---|---|
| DocCount | Number of documents in the table. |
| QPS | Number of successful queries per second. |
| ErrorQPS | Number of failed queries per second. |
| Latency | End-to-end time to process a query request. |
QRS
The QRS section shows metrics for the Query Result Searcher (QRS) worker, which receives incoming queries, parses them, and formats responses before returning results to the caller.
| Metric | Description |
|---|---|
| EmptyQPS | Number of queries per second that return empty results. |
| QueryLength | Size of incoming query requests. |
| ParseQueryLatency | Time the QRS worker spends parsing a query request. |
| ResultLength | Size of the raw query results before formatting. |
| ResultCount | Number of documents returned. |
| ResultFormatLatency | Time the QRS worker spends formatting query results. |
Searcher
The Searcher section shows metrics for the Searcher worker, which executes searches against the vector index and returns matching documents to the QRS worker.
| Metric | Description |
|---|---|
| QPS | Number of queries the Searcher worker processes per second. |
| ProcessLatency | Time the Searcher worker spends processing a query request. |
| FetchFieldsLatency | Time the Searcher worker spends retrieving the requested return fields. |
| OutputCount | Number of results the Searcher worker outputs. |
| RecallRatio | Recall ratio of the vector index. |
| VectorIndexLatency | Time consumed to perform vector indexing. |
DataUpdate
The DataUpdate section shows metrics for data updates.
| Metric | Description |
|---|---|
| ProcessedDocSize | Total size of documents processed. |
| End2EndLatency | Time consumed for end-to-end data processing. |
| rtIndexMemoryUse | Current memory used by the real-time index. |
| RtIndexMemoryUseRatio | Ratio of real-time index memory usage to total available memory. |
