What are Microsoft Exchange Server monitoring tools?

Microsoft Exchange Server is the most widely used email, calendaring, and communication server. Its popularity arises from its ease of use, powerful applications, and clear navigation controls – mainly because of its familiar GUI – and its proven performance, robustness, and reliability.

Like all servers, Exchange also needs to be monitored and tracked to make sure it is always at optimal performance levels.

Even though its own administration and configuration dashboard can do much of the monitoring well, it can still be further enhanced – or even out-performed – by some of the best Microsoft Exchange Monitoring tools.

1. SolarWinds Server & Application Monitor (FREE TRIAL)

SolarWinds SAM - Exchange Server Monitoring vie

SolarWinds Server & Application Monitor (SAM) is an Exchange Server monitoring tool which has the ability to drill into any component for easier troubleshooting of server issues.

SolarWinds SAM was built to monitor Exchange Server for important metrics that could impact its performance: mailbox database size, mount status, replication status, information store, and much more; and when it detects an issue it triggers an alert.

It can drill right into an individual mailbox’s details and help with the decision on whether or not a large mailbox needs to be moved to another database in case there is a need to improve load distribution.

The tool also helps prevent email storms with the help of its Active Exchange Server Monitoring. With the help of SAM, admins can track critical aspects of Exchange like the Hub Transport Server, Mailbox Server, Edge Transport server, and the CAS – and a failure in any one of them will trigger alerts.

SAM has an added advantage as it allows the monitoring of servers other than Exchange Server itself – it can be used to monitor other supporting Microsoft servers, applications, and services that help keep Exchange Server up and running; examples are DNS, DHCP, IIS, and CRM servers.

It proactively alerts administrators to keep them informed while, at the same time, keeping an eye on forecasted storage metrics – using historical and real-time data – to keep Exchange operational into the future.

SAM automatically tracks and saves data about incidents, so it can be used in the future to easily troubleshoot issues; it also uses both real-time and historical Exchange Server performance data to allow admins to drill down into any older issues for more details – all thanks to SAM’s advanced reporting tools

PRTG tracks usage of critical information regarding mailboxes, public folders, subfolders, and the number of items in the outgoing queue of the Exchange Server. It ensures the security of an Exchange Server by testing the SSL (Secure Sockets Layer) connectivity to the port of a device. It also keeps track of other peripheral servers like the number of sent/received emails in an IIS server using WMI (Windows Management Instrumentation) or Windows performance counters, for example.

It’s easy to install and use – PRTG comes with a set of pre-configured sensors for Exchange that are created automatically during the setup process. Its highly customizable alert system allows for alarms to be triggered – this, in turn, allows for issues to be resolved before they build up.

Admins can check to see if a database is shared by too many users and, if needed, move a few of them to another database for optimal performance.

It can troubleshoot Outlook connectivity issues by measuring the number of requests per second or average response times, for example, using Web Access Counters. It tracks failures by identifying mailbox access failures, directory access failures, number of rejected inbound calls, and other details.

ManageEngine OpManager Exchange IS Monitor

Admins can use various tools to ensure Exchange Server security – against spam and viruses, for example – by monitoring details like scan time, the number of rejected or timed-out scan requests, and blocked recipients; they can also keep an eye on the server burden using load assessment counters and queue length counters.

ManageEngine OpManager can track communication issues in integrated dial-in access performance and even monitor emails, voicemails, faxes, calendar information, and contacts to make sure that all voice and email messages reach their destinations.

It measures memory and disk utilization while also keeping an eye on the status of various services that are critical for the performance of an Exchange Server. It monitors mailbox database sizes, queues, mounted status, mailbox quotas (both used and remaining), the total number of mailboxes, and the average mailbox size.

ManageEngine offers a free trial.

Choosing a Microsoft Exchange Server monitoring tool?

The email server is perhaps one of the most important servers on a corporate network. It is the communication server that everyone relies on to deliver messages, share ideas, and collaborate on. It, therefore, makes sense to have a dedicated Microsoft Exchange monitoring tool to keep an eye on this important asset.

Among the advantages of such tools we have:

  • Ensuring the health of Exchange Servers to guarantee uninterrupted communication.
  • Making sure an Exchange Server is up and running, relaying messages to destinations, and that it is in communication with other servers in the domain.
  • Keeping on top of issues before they occur and troubleshooting them for quicker resolution.
  • Keeping and updating audits to help with reporting, troubleshooting, and tracking.
  • Informing administrators and users about stuff like policies or discrepancies in bandwidth or storage utilization to prevent bottlenecks or even total server crashes.
  • Sending – and if necessary or unanswered, escalating of – smart alerts to administrators to improve tech-support response times.
  • Checking configurations and monitoring packets and traffic to making sure an Exchange Server hasn’t been taken over by malicious code or entities for spamming and spoofing purposes, for example.
