Targeting Performance Counters
The following table describes the targeting performance counters that you should monitor for data that relates to LRU cache, Expression Evaluator, and Direct Mailer jobs. You can use the results of these performance counters to analyze the number of errors, messages, expressions, and entries in the cache to make sure that performance falls within the expected range.
Note
LRU cache objects are deprecated in Microsoft Commerce Server 2009. The LRU Cache performance counters are provided for backward compatibility.
You can find these counters in Microsoft Windows Server System Monitor. The System Monitor organizes performance counters by performance object. You should monitor your site by using performance counters and view the results collectively.
Commerce: Targeting
Counter name |
Description |
|---|---|
DML: Direct Mail Errors/sec |
The number of errors returned by Direct Mailer per second. |
DML: Direct Mail Jobs Running |
The total number of Direct Mailer jobs currently running. |
DML: Mail Messages Sent/sec |
The number of mail messages sent, by all Direct Mailer jobs per second. |
DML: Total Direct Mail Errors |
The total number of errors returned by all Direct Mailer jobs. |
DML: Total Messages Sent |
The total number of mail messages sent by all Direct Mailer jobs. |
EEE: Evaluations/second |
The number of expressions evaluated per second. |
EEE: Expression Cache Size |
The total number of expressions currently in the expression cache. |
EEE: Property Cache Hits |
The total number of property cache hits since the system started. |
EEE: Property Reads |
The total number of properties read by the Expression Evaluator since the system started. |
EEE: Property Reads/second |
The number of properties read by the Expression Evaluator per second. |
EEE: Result Cache Hits |
The total number of result cache hits since the system started. |
EEE: Total Evaluation Errors |
The total number of evaluation errors returned. |
EEE: Total Evaluations |
The total number of evaluations returned since the system started that includes both successful and incorrect evaluations. |
LRUCache: Cache Size |
The total number of entries in the cache. Cache size can grow to 10 percent more than the size set by the user, at which time, a flush will occur to bring the cache size back to the preset limit. LRUCache counters are grouped by site, not by the individual cache. |
LRUCache: Flushes/sec |
The number of items flushed out of the cache per second to deal with new items added to the cache. Records items flushed by the LRU algorithm and items flushed manually. |
LRUCache: Hits/sec |
The number of cache hits per second for the cache. |
LRUCache: Misses/sec |
The number of cache misses per second for the cache. |
DML: Direct Mail Jobs Running Performance Counter
The Direct Mail Jobs Running counter measures the number of jobs that exist simultaneously. There is no specific synchronization method in this service. More jobs that are concurrent may generate more throughput.
