The key to solving any kind of problem is fault isolation. More time is spent on finding out what is causing the issue than actually fixing it. This is why application monitoring (of mission-critical applications like Email) is very important. Let’s take a look at what all affect the performance of an application. The three main pieces of the puzzle that contribute to application performance, or lack thereof, are the three usual suspects- network, server and the application itself. Slowdowns on the network and the server directly affect application performance.

  2. 2. AgendaMonitoring your email servers and applications, and having visibilityinto their faults, failures, slowdowns will help in quicker issue resolutionand improved business productivity.Here are some tips and tricks to help you understand what is needed toeffectively monitor email services..We’ll discuss…Fault Isolation for Application MonitoringMicrosoft Exchange MonitoringTroubleshooting Common Email Monitoring IssuesHow SolarWinds Server & Application Monitor can help you withEmail MonitoringMonitoring & Diagnosing Email Issues - Slide 2 -
  3. 3. Fault Isolation for Application Monitoring An application’s performance is normally affected by one of the three: » Network » Server » Application It is important to find out the where the issue/fault/error has occurred in order to perform the necessary troubleshooting action A slowdown in the network or server will have a direct impact on the applications’ performance Visualize performance & availability of all components of the application in one view for quick isolation.Monitoring & Diagnosing Email Issues - Slide 3 -
  4. 4. Microsoft Exchange Monitoring Email Monitoring, in general, focusses on two areas » Monitoring the health of the email servers » Monitoring the health of the applications running on the email servers MS Exchange needs the following to function without issues: » An Internet connection (to send and receive emails) » A server with adequate resources (CPU, RAM, Disk I/O) » Core services up and running and receiving adequate physical resources like processor time and memory » Email database up and running and in a non-corrupted state Slowdown or failure of any one or combination of the above can cause MS Exchange to malfunction.Monitoring & Diagnosing Email Issues - Slide 4 -
  5. 5. Troubleshooting Email Monitoring Issues 1. Email is slow » Some network conditions that affect email delivery speed are: • Latency • Queuing delays • Routing loops, etc. » Physical constraints on the server that slowdown email are: • Over utilized CPU • Memory or high Disk I/O » Some application issues that impact email speed are: • Services hung/crashed • Memory leaks • Database corruptions Monitoring & Diagnosing Email Issues - Slide 5 -
  6. 6. Troubleshooting Email Monitoring Issues (contd.) 2. Cannot send email » Check if the network connection for the Exchange server is down » Check the Exchange services. An important one to look for here is MS Exchange Active Directory Topology service. Almost 80% of Exchange services and functions are dependent on this one service. » Simple things like Anti-Virus software installed on the Exchange server can make registry changes that prevent this all-important service from starting 2. Cannot receive email » In addition to the above, check your inbound SPAM rules and quarantined messages in your SPAM appliance. This might be the reason for not receiving emails.

  7. 7. How SolarWinds Server & Application Monitor (SAM)can help  SAM has built-in templates to monitor various useful attributes of the email server, and core applications running on it.  Monitors performance & user experience for virtually any application » Microsoft Exchange, Active Directory, IIS, any ODBC database, & more  Drill down to various components and attributes within an email server node to find the root cause of the issue  Use SAM’s built-in IMAP4 and POP3 User Experience Monitors to test email round trips from your SMTP mail server to your IMAP4 and POP3 mail servers and measure the time it takes to complete the trip Monitoring & Diagnosing Email Issues - Slide 7 -
