SharePoint Performance Counters
| Performance metric | Warning | Metric Description |
|---|---|---|
| SharePoint Publishing Cache: Number of cache Compactions | >2 | Indicates that the SharePoint cache may lack in size. |
| SharePoint Publishing Cache: Object cache flushes/Sec | >0 | Cache flushing during peak-use hours slows down performance. |
| SharePoint Publishing Cache: Object Cache Hit Ratio | <1 | Small number indicates the searches for non-published items. |
| SharePoint Publishing Cache: BLOB Cache % full | > 80% | Indicates that the SharePoint cache may lack in size. |
| ASP.NET Applications: Cache API trims | >1 | Indicates the lack of allocated memory for ASP.NET output cache. |
| ASP.NET: Requests Queued | >400 | Indicates the need for more Web Servers since a high number of requests can cause slow page load. |
| ASP.NET: Requests Rejected | >2 | Indicates the need for more Web Servers due to server busyness. |
| ASP.NET: Worker Processes Restarts | >1 | Any restarted worker process can indicate a potential problem. |
| Memory: Pages/Sec | >20 | Large value for page writes to memory indicates the lack of RAM memory. *Note: Tends to jump over 200 often. |
Microsoft SQL Server Performance Counters
| Performance metric | Warning | Metric Description |
|---|---|---|
| SQL Server General Statistics: User Connections | N/A | Number of users connected to the SQL server at the moment. Warning value is server dependent. |
| SQL Server Buffer Manager: Page life expectancy | <400 | Time the page is saved in the buffer cache, a low number indicates possible low RAM memory. |
| SQL Server Buffer Manager: Lazy Writes/Sec | >15 | Number of bad pages being removed from buffer per second. Zero is ideal. |
| SQL Server Buffer Manager: Buffer cache hit ratio | <90% | Percentage of data successfully fetched from a cached page. Low RAM memory indicator. |
| SQL Server SQL Statistics: Batch Requests/Sec | >1000 | Indicator of CPU usage by SQL Server affected by number of queries. |
| SQL Server SQL Statistics: SQL Compilations/Sec | >100 | Large number of compilations per second indicates high resource usage. |
| SQL Server Access Methods: Page Splits/Sec | >200 | Large number of page splits indicates high resource usage |
SQL Server Access Methods: Full Scans/Sec |
>100 | Full scans value can be ignored unless it peaks proportionally to CPU. |
SQL Server Locks: Lock Waits/Sec |
>1 | Indicates time passed for one server lock. |
| SQL Server Locks: Number of Deadlocks/Sec | >1 | Number of deadlocks on the SQL Server per second. |
| SQL Server Cache Manager: Cache Hit Ratio • > 85% • | <85% | Indicates the ratio between cache hits and lookups for plans. |
| SQL Server Databases: Transactions/Sec | N/A | Number of transactions per second on the SQL server, warning value is server dependent. |
