  8. View normal events, such as: • Event ID 8000 and 8001 • Event ID 700 and 701 • Event ID 1206 and 1207 View problematic events, such as: • Event ID 2064 and 2069 • Event ID 9582 • Events containing error 1018 JET_errReadVerifyFailure, 1019 JET_errPageNotInitialized, and 1022 JET_errDiskIO View additional event sources, such as: MSExchangeTransport, MSExchangeAL, MSExchangeIS and MSExchangeSA What to View in Event Viewer Use Event Viewer to monitor hardware and software activities Administrator

  9. To configure diagnostic logging: To view Exchange-related event sources: Open Event Viewer Select Application Log Select a specific set of events or leave the default setting Open the Properties dialog box of the server Configure the logging level for each service and category that you want to configure diagnostic logging for 1 1 2 2 3 Practice How to Monitor Event Viewer for Potential Issues A higher level of logging enables you to view more events in the Application log, and improves chances for determining the cause of the problem

  10. To verify server and connector status: Browse to Monitoring and Status Review the Status column for an indication of a potential issue 1 2 Practice How to Check Monitoring and Status for Potential Issues

  11. Queue viewer A utility to maintain and administer the organization messaging queues What Is Queue Viewer?

  12. To determine a problem witha queue: To find a message: Select the Queues node for the server you want to view Review the Status column Review the Number of messages and Total message size columns Select the queue in which you want to search for messages Search for messages View information about the messages found 1 1 2 2 3 3 Practice How to Monitor Queues for Potential Issues Use the Find Messages feature and the queue viewer to check for problem messages

  13. Lesson: Performing Scheduled Exchange Maintenance • What Are the Scheduled Maintenance Tasks? • Guidelines for Generating Reports and Identifying Trends • How to Review Protocol Logs for Potential Issues • What Is HTTP Monitor? • How to Monitor Outlook Web Access Servers for Potential Issues • How to Manage Mailbox Limits • How to Manage the Badmail Folder • How to Manage the Postmaster Mailbox

  14. What Are the Scheduled Maintenance Tasks? To perform scheduled maintenance tasks: • Generate reports and identify trends • Review protocol logs for potential issues • Monitor Outlook Web Access servers for potential issues • Manage mailbox limits • Manage the Badmail folder • Manage the Postmaster mailbox Administrator

  15. Monitoring and measurement tasks • Provide procedures for system monitoring • Provide procedures for system measurement Providing capacity planning • Establish baselines for each service • Monitor all levels of system operations Capturing and reporting performance data • Record and log system activity over a period of time • Chart the activity in real time and display information contained in log files Analyzing trends • Capture data and analyze the reports that you create by using that data Practice Guidelines for Generating Reports and Identifying Trends

  16. Practice How to Review Protocol Logs for Potential Issues Types of file formats for a protocol log: IIS Log NCSA Common Log ODBC Logging W3C Extended Log To enable the SMTP, NNTP, or HTTP protocol logging: Use the Properties dialog box of the virtual server to enable SMTP or NNTP protocol logging ‑ or ‑ Use the Properties dialog box of the Default Web Site to enable HTTP protocol logging Select a file format Specify the schedule and location for new log files Select the items you want to track if the file format is W3C Extended Log 1 2 3 4

  17. Real-Time Sampling Service Components SQL Reporting Server Client Monitor HTTP Monitor Benefits • Allows you to monitor Web sites • Allows you to test several sites and applications simultaneously • -------- • -------- • -------- • -------- Log File What Is HTTP Monitor? Checks Web sites Stores the results

  18. To install and configure HTTPMon: To run HTTPMon: Run Setup.exe from the Resource Kit Specify the appropriate information in the Setup program Run HTTPMon Configuration Manager .exe Configure Global Settings Add your server Start HTTPMon View the results by opening the .csv files Review events in Event Viewer 1 1 2 2 3 4 3 5 How to Monitor Outlook Web Access Servers for Potential Issues

  19. Practice How to Manage Mailbox Limits To use Exchange System Manager to manage mailbox limits: To respond to oversized mailboxes: Open System Manager Select Start Mailbox Management Process 1 Browse to the Servers container Browse to Mailbox Store and select Mailboxes Select Add/Remove Columns Select Storage Limits 1 2 2 3 4 Configure diagnostic logging on your server to see events in the Event Viewer application log when mailboxes reach the various stages of storage limit warnings • No Checking • Below Limit • Issue Warning • Prohibit Send • Mailbox Disabled

  20. To configure the location of the Badmail folder: To manage the Badmail folder: • Check the contents of the Badmail folder for messages that could not be delivered • Delete messages from the Badmail folder based on your company’s policies Select the virtual server that you want to configure Specify the new location for the Badmail folder 1 2 Practice How to Manage the Badmail Folder Home folder Virtual Server Badmail folder Define policies to monitor the Badmail folder

  21. To manually set an SMTP Postmaster mailbox to receive NDRs: Select the user account Create an SMTP proxy address Define that address on the virtual server 1 2 3 Practice How to Manage the Postmaster Mailbox To manage the Postmaster mailbox: Change the default display name to prevent displaying the name of your administrator account to outside users • Determine whether to associate or create a postmaster account • Delegate access to the postmaster’s mailbox • Establish a regular schedule • Determine if NDRs are to be sent to the postmaster account To change the origin of delivery status notifications: Remove the SMTP proxy address Locate the account and specify the postmaster address Change the Display Name 1 2 3

  22. Lesson: Performing On-Demand Exchange Maintenance • What Are the On-Demand Maintenance Tasks? • Why Defragment the Database? • How to Defragment Exchange Stores • How Isinteg Verifies the Exchange Store Integrity • How to Verify the Exchange Store Integrity • What to Look for When Checking Queues • Guidelines for Configuring a Performance Console

  24. Why Defragment the Database? Perform an offline defragmentation to reduce the database size and create a compacted database Use the Eseutil command-line tool to defragment the information store in Exchange Server 2003 Requirements for defragmenting: • Database must not be mounted • Free disk space at least 110 percent of the size of the database being processed

  25. To defragment mailbox and public folder stores by using Eseutil: Use Exchange System Manager to dismount the Exchange store that you want to defragment At the command prompt, run eseutil /d 1 2 Practice How to Defragment Exchange Stores

  26. 2 ? Browses all of the cross reference tables for errors 4 3 Compares the counts found to the counts in the reference database Performs the named to ID or named properties cleanup check How Isinteg Verifies the Exchange Store Integrity Use the Isinteg command-line tool to search an offline information store for integrity weaknesses and to repair detected issues 1 ? Checks whether MSExchangeIS service is stopped

  27. Practice How to Verify the Exchange Store Integrity Syntax: Isinteg -s ServerName [-fix] [-verbose] [-l LogFilename] -test TestName[[, TestName]...] To fix inconsistencies and errors in the Exchange store, at a commandprompt type: To test the integrity of the Exchange store, at a command prompt type: c:\program files\exchsrvr\bin>isinteg -s ServerName -fix c:\program files\exchsrvr\bin>isinteg -s ServerName -test alltests

  28. Check messages by using Queue Viewer Indicates an abnormal system event that warrants your attention • Indicates that a: • Server is down • Service is stopped • Network disruption is preventing the system from establishing a connection Indicates e-mail loop or DoS attack What to Look for When Checking Queues Extended periods of queues Spikes in queued messages Administrator

  29. Guidelines for creating a Performance console: To manually set an SMTP Postmaster mailbox to receive NDRs: Create a Performance console that has two different sample times Include a minimal set of counters in each console Examine your busiest server Save reference logs 1 2 Select the user account Create an SMTP proxy address Define that address on the virtual server 1 3 2 4 3 Guidelines for Configuring a Performance Console Create a Performance console to ask some basic questions about your environment • To monitor: • Use Microsoft Operations Manager to automate the monitoring of large numbers of servers and their applications • Use Exchange Application Management Pack to analyze and graph the performance data
