Searcher worker metrics
Parameter | Description |
procCpu | The CPU utilization. |
procMemRss | The amount of resident set size (RSS) memory that is used. |
procMemRssRatio | The memory usage. |
Query metrics
Parameter | Description |
inQpsPhase1 inQpsPhase2 | The number of independent phase-1 queries or phase-2 queries that are performed on Searcher per second. |
emptyQrsPhase1 | The number of phase-1 queries that are performed on Searcher per second. |
Query duration metrics
Parameter | Description |
requestPoolWaitTime | The period of time for which a request waits to be executed on Searcher. |
beforeSearchLatency | The period of time that is required by Searcher to execute the init function. The value is calculated based on the following formula: beginSession - rankStart. |
rankLatency | The period of time that is required by Searcher to perform rough sorting. |
rerankLatency | The period of time that is required by Searcher to perform fine sorting. |
extraRankLatency | The period of time that is required by Searcher to perform the final sorting. |
afterSearchLatency | The interval between the point in time when Searcher completes sorting and the point in time when Searcher returns the result. |
fetchSummaryLatency | The period of time that is required by Searcher to retrieve summary information. |
extractSummaryLatency | The period of time that is required by Searcher to create a dynamic summary. |
SearcherProcessLatencyPhase1 SearcherProcessLatencyPhase2 | The period of time that is required by Searcher to perform phase-1 queries or phase-2 queries. |
sessionLatencyPhase1 sessionLatencyPhase2 | The period of time that is required by Searcher to process sessions in Phase 1 or Phase 2. The value is calculated based on the following formula: PoolWait + ProcessLatency. |
aitheta_seek_latency | The period of time that is required to perform vector indexing. |
Query result metrics
Parameter | Description |
seekCount | The exact total number of documents that the system seeks in layers. |
seedDocCount | The number of documents that match the search query. |
matchCount | The exact total number of documents that match the search query in all layers during inverted indexing. The value is calculated based on the following formula: Number of documents that the system seeks - Number of documents that are filtered out. |
seekDocCount | The number of documents that Searcher scanned. |
reRankCount | The number of documents that are finely sorted. |
matchDocSize | The number of matched documents that are returned by Searcher in Phase 1. |
totalFetchSummarySize | The number of fields that are included in the summary that is retrieved by Searcher. |
aitheta_seek_sount | The number of documents that the system seeks during vector indexing. |
aitheta_recall_ratio | The retrieval ratio of vector indexes. |
Index metrics
Parameter | Description |
partitionDocCount | The number of documents in a partition. |
segmentCount | The number of segments in a partition. |
deletedDocCount | The number of deleted documents in a partition. The value is obtained based on delete mapping. |
partitionMemoryUse | The memory that is used by a partition. The value is calculated based on the following formula: + + |
incIndexMemoryUse | The memory that is used by incremental indexes. This value is equal to the total memory that is used by mmap lock files, slice files, in_mem files, and cache files. |
oldInMemorySegmentMemoryUse | The memory that is used by segments that are not released. The memory that is used by each segment includes the memory that is used by SegmentWriter and OperationWriter. |
rtIndexMemoryUse | The memory that is used by real-time indexes. The value is calculated based on the following formula: + |
rtIndexMemoryUseRatio | The real-time memory usage. |
buildingSegmentMemoryUse | The memory that is used by Building Writer, including the memory that is used by SegmentWriter, PartitionModifier, and OperationWriter. |
addQps | The number of add queries that are performed per second in real time. |
deleteQps | The number of delete queries that are performed per second in real time. |
buildQps | The number of build queries, including add, delete, and update queries, that are performed per second in real time. |
dumpSegmentLatency | The real-time segment dump duration. |
end2endLatency | The real-time data latency that indicates the interval between the point in time when data is pushed to the engine and the point in time when the data is available for search queries. |
SQL query metrics
Parameter | Description |
qps | The number of SQL queries that are performed per second. |
totalLatency | The query duration. |
