eG Monitoring
 

Measures reported by SybStmtStatsTest

This test reports critical resource usage and general performance statistics related to transactions that are executed on the Sybase server. For execution, this test requires the enable monitoring, statement statistics active, per object statistics active, statement pipe max messages, and statement pipe active configuration parameters to be enabled.

 The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
AvgCpuTime Indicates the average cpu time consumed by the transactions to this database. MillSec Ideally, this value should be low. If the value is high, then use the detailed diagnosis of this measure to view the top transactions in terms of CPU consumption. Such transactions can then be fine-tuned, so that they are more resource-efficient.
MaxCpuTime Indicates the maximum CPU time of transactions to this database. MillSec  
AvgLogicalReads Indicates the average number of logical reads performed by the transactions to this database. number Use the detailed diagnosis of this measure to view the complete details of transactions causing logical reads to occur on the database.
MaxLogicalReads Indicates the maximum number of logical reads performed by transactions to this databases number  
AvgPhysicalReads Indicates the average number of physical reads performed by transactions to this database. number Physical database reads can cause processing overheads to escalate, thereby affecting database performance. These transactions therefore have to be minimized. If the value of this measure is very high, then use the detailed diagnosis of this measure to view the details of the transactions that are causing physical reads to occur.
MaxPhysicalReads Indicates the maximum number of physical reads performed by transactions to this database. number  
AvgPageModified Indicates the average number of pages modified by transactions to this database. number Use the detailed diagnosis of this measure to view the details of transactions that are modifying pages.
MaxPageModified Indicates the maximum number pages modified by transactions to this database. number  
AvgLongWaited Indicates the average execution time of transactions that have taken too long to execute. Millsec If the value of this measure is high, it could indicate that one/more inefficient queries are executing on this database. You might then have to use the detailed diagnosis of the measure to view the top transactions in terms of execution time, and identify that transaction that has taken the longest to execute. Fine-tune the transaction to prevent database slowdowns."
MaxLongWaited Indicates the maximum number of times transactions waited in a database. Millsec
