Module 11 Maintaining Microsoft Exchange Server 2010

Module Overview Monitoring Exchange Server 2010 Maintaining Exchange Server 2010 Troubleshooting Exchange Server 2010

Lesson 1: Monitoring Exchange Server 2010 Why Is Performance Monitoring Important? Tools for Monitoring Exchange Server Collecting Performance Data for the Exchange Server Collecting Performance Data for the Mailbox Server Collecting Performance Data for the Hub Transport and Edge Transport Servers Collecting Performance Data for the Client Access Server Using the Collected Performance Data

Why Is Performance Monitoring Important? Performance monitoring can help you: Identify performance issues Identify growth trends to improve plans for upgrades Measure performance against service level agreements Identify security issues and denial-of-service attacks

Tools for Monitoring Exchange Server The following tools can help you monitor system health: System Center Operations Manager or System Center Essentials (with Exchange Server 2010 Management Pack) Third-party monitoring products Performance and Reliability Monitor

Collecting Performance Data for the Exchange Server Suggested performance counters for all Exchange Server roles: Processor: _Total\% Processor Time _Total\% User Time _Total\% Privilege Time System: Processor Queue Length MSExchange ADAccess Domain Controllers: LDAP Read Time LDAP Search Time LDAP Searches time out per minute Long running LDAP operations/min Memory: Available Mbytes Pool Paged Bytes Transition Pages Repurposed/sec Page Reads/sec Pages/sec Page Input/sec Pages Output/sec

Collecting Performance Data for the Mailbox Server Suggested performance counters for all Mailbox server roles: LogicalDisk: Avg. Disk sec/Read Ave. Disk sec/Write Avg. Disk sec/Transfer MSExchangeIS Mailbox: Messages Queued for Submission MSExchangeIS: RPC Requests RPC Averaged Latency RPC Operations/sec RPC Num Slow Packets RPC Average Latency MSExchangeIS Public: Messages Queued for Submission

Collecting Performance Data for the Hub Transport and Edge Transport Servers Suggested performance counters for the Hub Transport and Edge Transport server roles: LogicalDisk: Avg. Disk sec/Read Avg. Disk sec/Write Avg. Disk Queue Length MSExchange Database ==> Instances: Log Generation Checkpoint Depth Version buckets allocated Log Record Stalls/sec MSExchangeTransport Queues: Aggregate Delivery Queue Length (All Queues) Active Report Delivery Queue Length Active Mailbox Delivery Queue Length Retry Mailbox Delivery Queue Length Unreachable Queue Length Largest Delivery Queue Length Poison Queue Length

Collecting Performance Data for the Client Access Server Suggested performance counters for the Client Access server role: LogicalDisk: Avg. Disk sec/Read Ave. Disk sec/Write ASP.NET: Application Restarts Worker Process Restarts Requests Current Request Wait Time MSExchange OWA: Average Response Time Average Search Time MSExchange ActiveSync: Average Request Time MSExchangeFS OAB: Download Task Queued RPC/HTTP Proxy: Number of failed back-end connection attempts per second ASP.NET Applications: Requests in Application Queue MSExchange Availability Service: Average Time to Process a Free Busy Request

Using the Collected Performance Data To use the collected performance data: Create a baseline: Monitor performance for a full business cycle Note any peaks or troughs in the data Set warning and error level thresholds Review growth trends regularly to: Adjust threshold Adjust server configuration

Lesson 2: Maintaining Exchange Server 2010 Discussion: What Is Change Management? Considerations for Managing Change Process for Deploying Exchange Software Updates Determining the Need for Hardware Upgrades

Discussion: What Is Change Management? How does your organization address change management? Are there some situations where change management is more important than others? What are the benefits of having a formal change management process? Are there situations in which you cannot follow the normal change process?

Considerations for Managing Change Define a process and use it consistently Support the change management process Use a process model like MOF to describe a system life cycle

Process for Deploying Exchange Software Updates Exchange Server is updated with rollup packages and service packs When updating Exchange Server, consider the following: During update, Exchange Server connects to CRLs Update process may update customized Logon.aspx file for Outlook Web App Apply updates to the Internet-facing Client Access servers first Exchange Services are stopped during the update process DAG members should be updated by following a specific procedure

Determining the Need for Hardware Upgrades Investigate causes of poor user experiences Monitor processor counters Monitor memory counters Monitor disk counters Monitor network counters Scale out instead of scale up

Lesson 3: Troubleshooting Exchange Server 2010 Developing a Troubleshooting Methodology Troubleshooting Tools Discussion: Troubleshooting Mailbox Servers Discussion: Troubleshooting Client Access Servers Discussion: Troubleshooting Message Transport Servers

Developing a Troubleshooting Methodology Clearly define the problem 1 1 List the probable cause of the problem 4 4 Rank the cause by probability and define solutions 5 5 Rank solutions by ease of resolution and impact to complete 6 6 Try the most probable and easily implemented resolution until the problem is resolved 7 7 Gather information related to the problem Turn up logging Review logs Try to reproduce the problem 3 3 Reduce logging to normal 8 8 Document resolution and root cause for future reference 9 9 Define the problem scope 2 2

Troubleshooting Tools All Exchange servers: Best Practices Analyzer Performance Troubleshooter Network Monitor Performance and Reliability Monitor Test cmdlets Microsoft Remote Connectivity Analyzer Hub Transport and Edge Transport servers: Mail Flow Troubleshooter Message tracking Queue Viewer Routing Log Viewer Telnet

Discussion: Troubleshooting Mailbox Servers A database has gone offline. What process can you use to troubleshoot the problem?

Discussion: Troubleshooting Client Access Servers Outlook users no longer can connect to the system. What process can you use to troubleshoot the problem?

Discussion: Troubleshooting Message Transport Servers Users are reporting undeliverable and slow-to-deliver outbound . What process can you use to troubleshoot the problem?

Lab: Maintaining Exchange Server 2010 Exercise 1: Monitoring Exchange Server 2010 Exercise 2: Troubleshooting Database Availability Exercise 3: Troubleshooting Client Access Servers Logon information Estimated time: 60 minutes

Lab Scenario You are the messaging administrator at A. Datum Corporation. You need to configure basic monitoring by using the Performance and Reliability Monitor. You also must troubleshoot issues with a mailbox database and a Client Access server.

Lab Review Was the Exchange Best Practices Analyzer helpful in troubleshooting the database error? When might using Exchange Best Practices Analyzer be a better fit? Why do you need to run IISReset after reconfiguring Outlook Web App?
