Recently we covered what it means to configure server monitoring correctly, and the steps we can take to ensure that the information we get alerted on is useful and meaningful. We learned that improper configuration leads to support teams that ignore their alerts, and system monitoring becomes noise. Application monitoring isn’t any different, and what your organization sets up for these needs is likely to be completely different than what was done for your server monitoring. During this article we will focus on monitoring Microsoft Exchange on-premises, and what should be considered when choosing and configuring a monitoring tool to ensure that your organizational email is functioning smoothly to support your business.
Email Monitoring Gone Wrong
In the early days of server monitoring it wasn’t unusual for system administrators to spend months configuring their server monitoring tool for their applications. With some applications, this decision may be completely appropriate, but with Microsoft Exchange I have found that server monitoring tools typically are not enough to successfully monitor your organizational email system. Even if the server monitoring tool comes with a “package” that is specifically for monitoring email. The issue becomes that by default these tools with either alert on tool much or too little never giving your application owner exactly what they need.
So how can your business ensure that email monitoring is setup correctly, and that the information received from that tool is useful? Well it really comes down to several simple things.
- Evaluate several Exchange monitoring tools, and then choose a tool that will best suit your Exchange needs. In most cases this tool is not the same as your server monitoring tool.
- Implementation of Exchange monitoring should be project with a dedicated resource.
- The tool should be simple and not time consuming to configure. It should NOT take 6 months to be able to properly monitoring your email system.
- Choose a tool that monitors Active Directory too. Exchange depends heavily on Active Directory and DNS, so Active Directory health is also vital.
- Make sure you can easily monitor your primary email functionality. This includes email flow testing, your Exchange DAG, DAG witness, Exchange databases, ActiveSync, Exchange Web Services, and any additional email functionality that is important to your organization.
- Ensure that the tool selected has robust reporting. This will allow for time saving’s from scripting your own reports and allow for better historical trending of email information. These reports should include things such as mail flow SLA’s, large mailboxes, abandoned mailboxes, top mail senders, public folder data, distribution lists and more.
This approach will ensure that your email system will remain functional, and alert you before a real issue occurs. Not after the system has gone down.
Implementing the correct tool set for Microsoft Exchange monitoring is vital to ensuring the functionality and stability of email for your business. This is often not the same tool used for server monitoring, and should include robust reporting options to ensure your SLA’s are being met and that email remains functional for your business purposes.
