What is the NAV Nurse?

The NAV Nurse is our online monitoring service that tracks key indicators of a Navision, Dynamics NAV or Dynamics 365 Business Central system’s health in real-time. Its job is to alert us to issues with your system as they begin to develop.

To keep your system healthy, it must be regularly maintained and supported by the right hardware and network resources. Modifications need to be well architected. The NAV Nurse runs tests to measure and track Dynamics NAV and Business Central error codes, locking behaviour, disk capacity, memory, and processor utilisation. It then automatically alerts us to critical issues or degradation over time.

Benefits of the NAV Nurse service

By using the NAV Nurse, you can rest easy in the knowledge that potential system performance issues are being monitored by our expert team. The NAV Nurse is:


The NAV Nurse knows what factors have a big impact on your system health and alerts us to any potential issues before they become a problem.


Tests are run on your system non-invasively, meaning no adverse effects on performance or unexpected charges from extra usage requirements.


Data collected by the NAV Nurse is shared with our team and yours, so there is complete transparency on both sides.


Reports are only conducted on your system data, not the information within the system itself.


Any customer of TNP hosting their ERP solution on-premise or a Managed Service can benefit from this service (unless the same agent is already installed on the system by you or a third-party)

NAV Nurse - Work 600x600

How does the NAV Nurse work?

The NAV Nurse works by using modern performance monitoring software to spot potential issues in your systems before they become problematic.

It does this using the N-able N-central agent, which monitors the following things:

  • Memory and CPU usage
  • Disk Space
  • SQL - MAXDOP setting, max memory setup, Recovery module
  • Index rebuild job
  • Backup failures
  • Disk configuration
  • Locks and deadlocks
  • SSL certificate expiry date
  • Table sizes (change log and AutoNAV task log entry)

The system needs to be looked after and maintained. Many customers don’t

do this and delay seeking attention until the issue is serious, often painful and
sometimes expensive.

NAV Nurse - Alert to slice 600x600

What can the NAV Nurse alert you to?

We want to keep your systems as performant as possible. The NAV Nurse will help TNP and you to do that. We can stop issues before they become a problem, enabling you to continue with business-as-usual.

Some of the system performance issues we’ve come across are:

  • Impending expiry of SSL certificates: If not picked up until expiry date, this prevents access to your website until the SSL certificate is renewed.
  • Failure of backups: In a case of an Disaster Recovery situation, backups are crucial way to get you back up and running with minimal data and time loss.
  • The impact that limited system resources are having on system performance
  • Large size of change logs: The size of tables (both storage and record count) have direct impact on system performance. Correct management and maintenance is important but you first need to know if the data is growing too much.

NAV Nurse - Helped 600x600

Who has the NAV Nurse helped?

The NAV Nurse has alerted us and our customers to issues including locks, SSL certificate expiry, licence issues, table sizes and this has prevented some system stopping from working.

SSL certificates usually expire on Fridays - something you don't want to worry about just before the weekend! Where this has happened, we have been able to purchase the certificate ahead of expiry, schedule the renewal for a time that suited our customer and their users and have a seamless move from one to another.

The same goes for table sizes. We know that, as the change log table grows, it takes longer to write to and slows the process that it is trying to monitor. This gradually slows to a point that it is unusable. The NAV Nurse will highlight potential issues with the set up and allows for a solution to be planned and implemented prior to any visible issues.

Who can benefit from the NAV Nurse?

The NAV Nurse service is an integral part of our support offer – available to all our customers under the terms of their current contract.

Why can't I have the NAV Nurse if I'm on Business Central SaaS?

To allow us to monitor your system, we need to install RRM Agent on the servers. TNP (and you) don’t have access to those when on SaaS.

What if I already have N-Central Windows Agent installed by a third-party IT support/MSP?

If this agent is already installed then, unfortunately, we are unable to offer the NAV Nurse service due to conflicting software.

What are the common Dynamics NAV system performance issues you encounter?

There have been multiple areas of performance that NAV Nurse has identified, but some of the bigger ones are the number of records in change log, SSL certificate expiry and SQL configuration. There are other areas that we are planning to add as a metric and we will continue to expand as we find more suitable ones. You can break down the performance in a few different groups, the biggest ones being code issues, environment issues and workload. While NAV Nurse might not be able to identify the exact root cause, it will alert us to performance degradation.

What happens when NAV Nurse finds an issue?

If we are alerted to something that you, your IT company or TNP need to action, we will notify you with the details and raise an internal support ticket on your behalf. We will aim to offer suggestions or solutions. If, however, it is something that you or your IT company do not have the right skills for, we will be able to offer help, either under your support contract or as chargeable work.

How do TNP implement this agent into my systems?

We create a specific agent installation file for you that can be run on the relevant server, either by yourselves or our team.

What happens if I want to remove the agent?

The agent can simply be uninstalled directly from the server.
