Parameter Usage
===============
DatabaseAvailabilityGroup:
Name of database availability group. If nothing is specified then use the DAG which the
local node is a member of.
Database:
List of databases for which the *over report needs to be generated (can use wildcards)
e.g. -Database:"db1","db2"
-Database:"db*","Mailbox*"
TemporaryDataPath:
Location where temporary files will be stored. If nothing is specified, then
The name of directory will be decided by the following logic:
$env:SystemDriveTempCollectOverMetrics
StartTime:
Time at which the event data will start to be collected. If not specified, then
start time will be 12:00am yesterday
EndTime:
Time at which the event data will stop being collected. If not specified, then
collect events up to 11:59pm of yesterday
ReportPath:
Directory where the result of processing events will be stored
ReportAlias:
Email alias to which the generated reports needs to be emailed
IncludeApplogs:
Specify if application events should also be collected, merged and processed.
By default, the following providers will be included:
"MSExchangeIS", "MSExchangeIS Mailbox Store", "MSExchangeRepl"
AppLogProviders:
Specify if specific applog providers' events should be collected. If this is
specified, the above providers will not be included. Those need to be explicitly
specified again
AnalyzeOnly:
Specify if the data is already collected and only processing is required
MergedXmlFile:
Name of the file into which all of the event logs will be merged
GenerateHtmlReport:
Specify if a report needs to be prepared in a simple html table format for easy viewing
ShowHtmlReport:
Specify if an html generated report needs to be shown in an explorer window automatically
after it is generated
DotSourceMode:
Specify if nothing needs to be run immediately, but this file is dot sourced for using
powershell methods defined in it"
