The Http Indexing Service object counters report statistics regarding queries run by Indexing Service through Internet Information Service. Unlike other Indexing Service counters, which can report values even if Indexing Service is not being used in conjunction with a Web server, these counters only report values when Indexing Services queries are executed through the Web server.
| Counter Name | Description | Counter Type |
|---|---|---|
| % Cache Hits | Shows the percentage of queries that were found in the cache, out of the total number of times the cache was queried. | PERF_RAW_FRACTION |
| % Cache Misses | Shows the percentage of times queries that were not found in the cache, out of the total number of times the cache was queried. | PERF_RAW_FRACTION |
| Active Queries | Shows the current number of running queries. | PERF_COUNTER_RAWCOUNT |
| Cache Items | Shows the number of completed queries that are stored in the cache since the Web service was started and the first query was posted. | PERF_COUNTER_RAWCOUNT |
| Current Requests Queued | Shows the current number of query requests that are pending. | PERF_COUNTER_RAWCOUNT |
| Queries per Minute | Shows the number of queries executed per minute by the server. This counter can be used to determine server usage. | PERF_COUNTER_RAWCOUNT |
| Total Queries | Shows the total number of queries run since the service was started. | PERF_COUNTER_RAWCOUNT |
| Total Requests Rejected | Shows the total number of query requests that were rejected because the server was too busy. If this value begins to increase steadily, a bottleneck is developing. To alleviate this condition, reconfigure the server by adding more random-access memory (RAM) or use less resource-intensive queries. See the Indexing Service documentation for more information. | PERF_COUNTER_RAWCOUNT |
