1.Perfmon data collection: Collect performance data to log file or analyze previously collected logs. ExPTA can collect for durations between 5 minutes to 8 hours. Collection works remotely. Data is analyzed in 20 minute time ranges, and results are grouped by the time in which the problem occurred. You can analyze logs previously collected by ExPTA or via perfmon.ExPTA will expect that the performance counters listed below are included in any log that is analyzed.
4.LDAP latency checks: MSExchangeDSAccess Domain Controllers\LDAP Search Time and MSExchangeDSAccess Domain Controllers\LDAP Read Time thresholds were added to detect problems due to bottlenecks on the AD server.
5.RPC requests: Max RPC requests, average RPC request thresholds are now dependent on the number of users per server
6.Memory changes: Validate that the DatabaseCacheSizePeak < 1.2 GB.In addition, most of the memory rules have been changed to work off the maximum rather than the average values.
7.Improved reporting: Reporting of results between steps and the summary are now displayed in a consistent fashion, using tabbed pages for the different reports.
