10 Best Port Monitoring Tools in 2022
What is port monitoring?
Port is a point in a network where connection both starts, and ends. They are not physically hardwired (like the ethernet port) and are managed by the OS. Ports allow you to filter connections and easily recognize various sorts of traffic. Port monitoring enables you to make sure that your ports as they are supposed to and that there are not any losses of data, or connections refused.
What are the main benefits of Port Monitoring?
- Service reliability. You have one less thing to worry about with a port monitoring solution.
- Early detection of the root cause. Your service can crash for dozens of reasons. Having a monitoring solution for most of them will reduce the amount of time you need to discover the root cause.
- It's a simple, money-efficient, accurate, and yet powerful monitoring tool. A Port monitor is a periodic trigger, which sends a specific request to a given port yet can discover major flaws in the lifecycle of your software.
Best practices for Port Monitoring:
- Pick a suitable monitoring frequency. A long-trigger period can increase the downtime since it will take much longer to discover an issue. Too frequent checks could possibly waste resources. Try to stay within a range of minutes.
- Don't forget about the DNS. DNS is often called the Death Star exhaust port equivalent, and it is not far from the truth. Many people ignore the necessity of DNS monitoring because it is mainly provided by their hosting provider. Even if you don't have access to administration, you should monitor it because you can find the root cause more quickly and hold your partners accountable for any outages. You can read more about DNS attacks over at CyberNews.
- Go worldwide monitor your ports from various geographical locations. While monitoring behind the firewall is safe and efficient, it will not discover geography-related outages.
- Don't try to DIY if you don't have to. There are many open-source, free, or affordable monitoring solutions for port monitoring, or those that include it. Trying to re-invent the wheel will cost you time and money.
