For many organizations, Exchange is the communications
lifeblood without which business comes to a standstill. Without it, customers
become detached from support and sales personnel. As such, keeping these
Exchange servers in good health is of prime importance.
Exchange includes some built-in resource monitors that will
alert you when some component of your server has gone awry and needs attention.
To get started, open the Exchange System Manager. Once open, expand the
Administrative Groups > First Administrative Group > Servers branch and
right-click the server for which you would like to configure monitoring. From
the resulting shortcut menu, choose the Properties option and, from the
Properties window, select the Monitoring tab.
With this tab, you can configure a number of different
monitors, including:
- Available
virtual memory: Determine at what point warning and critical states are
initiated for virtual memory. When virtual memory on your Exchange system
gets too low, Exchange may stop working. Use this option to alert an
administrator via e-mail when available virtual memory drops below a level
that specify. With this option, you need to tell the monitoring service
for how many minutes virtual memory needs to be below the target
percentage before an administrator is notified. - CPU
utilization: Consistently high CPU utilization on your Exchange server may
indicate a need to add additional resources to your Exchange environment. Again,
you can tell the Exchange monitor at what point warning and critical
states are initiated and an administrator can be notified when these
targets are hit. Like virtual memory, CPU utilization needs to stay peaked
beyond your target percentages for a certain number of minutes (that you
specify) before any action is taken. - Free
disk space: Allows you to define warning and critical states that are
based on the amount of disk space available on your Exchange system. Exchange
is very disk intensive, and having enough space to grow is critically
important. - SMTP
queue growth: If a queue continually grows, it can signal that one of your
connectors is on the fritz and not sending messages. For this monitoring
object, you can specify the number of minutes of continual growth after
which the queue is placed into a warning or critical state. - Windows
2000 service: Allows you to watch specific Windows services and throw an
error and notify an administrator when a service stops. - X.400
queue growth: Same as SMTP queue growth, but watches the X.400 queue.
To add one of these items, click the Add button. From the
Add Resource window, choose the resource from the list above that you want to
monitor. For any selection, you will have to make some choices about warning
levels and timing. (For example, if you choose CPU utilization, you’re asked to
provide a duration and CPU thresholds.) Click OK when
you’re finished.
Now, in order to notify an administrator via e-mail when one
of your warning thresholds is violated, you need to tell the Exchange System
Manager who should get these reports. Here’s how:
- In the
manager, go to Tools > Monitoring and Status > Notifications. - Right-click
Notifications and choose New > E-mail Notification - In the
resulting window, provide the e-mail address of an administrator and
decide under which condition–warning or critical–you want to email the
administrator. You can set up separate notifications for each state. - Also,
specify the name of the mail server that should be used to send the
notification. If possible, use a different server that the monitored
system to send the message. - Click
OK when you’re finished.
