Microsoft Exchange Server Monitoring
Exchange Server's architecture consists of many components and dependencies. This expansive surface makes it more important than ever to monitor. Some of the Exchange Architecture Components include:
  • Simple Mail Transfer Protocol (SMTP) that transports electronic mail across the network.
  • Exchange Information Store (IS) that manages Microsoft Exchange Information Storage.
  • Exchange MTA Stacks that provide Microsoft Exchange X.400 services.
  • Exchange Routing Engine that processes Microsoft Exchange routing information.
  • Exchange System Attendant that provides system related services for Microsoft Exchange.

Monitoring Exchange Server complexity requires continually looking at all elements involved to know and understand if health and performance is optimal. Each Exchange Server aspect is important including:

  • Connections & Queues
  • Database Size
  • SMTP Availability
  • Process Utilization
  • Services states and events
  • Eventlog Errors, Warnings, and Informational Events
  • Underlying Platform Performance
  • Dependent Infrsutructure Performance
Customizable Microsoft Exchange Server Dashboards
Live performance dashboards give you the performance metrics,  and events of Microsoft Exchange Server in a single view with quick link access to powerful analytical charting. Dashboards include:
  • Exchange Server Database
  • Exchange Server Processes
  • Exchange Server Queues
  • Exchange Server SMTP
  • Exchange Server Spam
  • Exchange Server Summary
Powerful Analytics

  		The tools make the difference when finding the root-cause of performance bottlenecks, application faults, and performing trend analysis. Analytical Charting features include:
  • Correlation of Live or Historical Data
  • Drill-Down, Zoom, and Statistic Lines
  • OpenGL 3D Surface Analysis
  • Live, Second, Minute, Hourly, and Monthly Data Periods

  Other I/O
  \Database()\Database Cache % Hit
 
  Database Cache % Hit is the percentage of database file page requests that were fulfilled by the database cache without causing a file operation. If this percentage is too low, the database cache size may be too small.
  \Database()\Database Cache Size
 
  Database Cache Size is the amount of system memory used by the database cache manager to hold commonly used information from the database file(s) to prevent file operations. If the database cache size seems to be too small for optimal performance and there is very little available memory on the system (see Memory/Available Bytes), adding more memory to the system may increase performance. If there is a lot of available memory on the system and the database cache size is not growing beyond a certain point, the database cache size may be capped at an artificially low limit. Increasing this limit may increase performance.
  \Database()\Database Page Faults/sec
 
  Database Page Faults/sec is the rate that database file page requests require the database cache manager to allocate a new page from the database cache.
  \Database()\I/O Database Reads/sec
 
  I/O Database Reads/sec is the rate of database read operations completed.
  \Database()\I/O Database Writes/sec
 
  I/O Database Writes/sec is the rate of database write operations completed.
  \Database()\I/O Log Reads/sec
 
  I/O Log Reads/sec is the rate of logfile read operations completed.
  \Database()\I/O Log Writes/sec
 
  I/O Log Writes/sec is the rate of logfile write operations completed.
  \Database()\Log Record Stalls/sec
 
  Log Record Stalls/sec is the number of log records that cannot be added to the log buffers per second because they are full. If this counter is non-zero most of the time, the log buffer size may be a bottleneck.
  \Database()\Log Threads Waiting
 
  Log Threads Waiting is the number of threads waiting for their data to be written to the log in order to complete an update of the database. If this number is too high, the log may be a bottleneck.
  \MSExchangeIS\Active Connection Count
 
  Number of connections that have shown some activity in the last 10 minutes.
  \MSExchangeIS\RPC Averaged Latency
 
  RPC latency in milliseconds averaged for the past 1024 packets.

  Processes
  \Process(emsmta)\% Processor Time
 
  % Processor Time is the percentage of elapsed time that all of process threads used the processor to execution instructions. An instruction is the basic unit of execution in a computer, a thread is the object that executes instructions, and a process is the object created when a program is run. Code executed to handle some hardware interrupts and trap conditions are included in this count.
  \Process(emsmta)\Handle Count
 
  The total number of handles currently open by this process. This number is equal to the sum of the handles currently open by each thread in this process.
  \Process(emsmta)\IO Read Bytes/sec

  \Process(emsmta)\Page Faults/sec
 
  Page Faults/sec is the rate at which page faults by the threads executing in this process are occurring. A page fault occurs when a thread refers to a virtual memory page that is not in its working set in main memory. This may not cause the page to be fetched from disk if it is on the standby list and hence already in main memory, or if it is in use by another process with whom the page is shared.
  \Process(emsmta)\Private Bytes
 
  Private Bytes is the current size, in bytes, of memory that this process has allocated that cannot be shared with other processes.
  \Process(emsmta)\Thread Count

  \Process(exmgmt)\% Processor Time
 
  % Processor Time is the percentage of elapsed time that all of process threads used the processor to execution instructions.
