4 ways NOC teams monitors your network for any changes that might affect performance, such as configuration updates and software updates.

Network Monitoring By Network Operations Centers

In general, NOC teams monitor the network for changes that could affect performance, such as configuration updates and software updates. Network engineers handle this task.

4 ways to monitor network changes

However, NOC teams that monitor these changes are more likely to detect performance issues sooner. It is important for the tool to not only monitor performance and availability but also track configuration changes. The following are few different types of configuration changes that should be monitored.

Changes NOC monitor for —

  1. A change in the device’s running state

If someone logs into a network device and makes changes, the device’s state can change. Most network devices have a configuration file that contains parameters for booting the device. Any changes to the running state affect the device that is running, but not the configuration file.

When a change is made incorrectly, a performance problem occurs. The NOC operator then attempts to diagnose the issue. Since the operator may not always be aware of the change, it can take some time for it to be discovered.

Monitoring and configuration tools for networking can speed up troubleshooting by showing the NOC operator changes made to the device. In that case, the operator can send that information to the network engineers, who won’t have to search for the problem. There is also a chance the tool will enable the NOC operator to fix the issue without involving the network engineers.

2. Changes not saved

When a performance problem is addressed through an unsaved change, the person making the change never saves the change to the boot configuration file. Changes must be reported to the NOC team that haven’t been saved because the performance problem will reappear after a reboot of the router.

The NOC team can use this information to alert network engineers when a change is made but doesn’t get saved.

Any unsaved changes can be detected by a networking performance monitoring and configuration tool. It will also show the difference between the “fixed” configuration that wasn’t saved and the “unfixed” one from the configuration file after a reboot.

3. Changing the boot configuration of the device

A change window occurs in most IT departments during the midnight hours when a change affects the fewest users.

Consider a case where a new regulation has gone into effect and a company’s network device must be modified to adhere to the new rule. Changing the boot configuration is not a critical change, so the network engineer does it during the normal change window. However, not every change that a person makes will work the way it is supposed to.

The change the network engineer made could have a negative side effect if the device is rebooted, likely in the middle of the night. This can happen either right away or after a lot of people are using the network.

Most of the time, the NOC operator will observe a huge performance problem and need to find out what caused it. By using the network performance monitoring and configuration tool, the IT manager can check what changed and how it performed. In some cases, the tool can track the performance back for 30 days.

An operator can notify network engineering of the possible source of the performance problem. “We’ve got a performance problem. By the way, there was a change at 2:00 a.m. Maybe that can help or perhaps that is the problem.”

4. The device has been updated with software

In this case, the change is software-based rather than configuration-based. Vendors such as Apple, Microsoft, and Cisco often release software updates that don’t always work as intended and may have negative consequences.

In addition to software updates, change windows are also commonly scheduled for these purposes. Changes in the device’s boot configuration can have a delayed negative impact. As an example, the change in the device’s boot configuration.

The network engineering team will be able to determine the potential problem if the network operators are using network performance monitoring and configuration software.

Are you having issues with network monitoring and troubleshooting?

The Field Engineer can help you if you have tried the network monitoring steps above and are still having trouble getting everything online or you lack the technical know-how or confidence to implement them. Bring a technician into your business who can troubleshoot network issues, as well as implement solutions to prevent downtime.
