Trusted by teams at companies around the world

"Pulsetic made monitoring something I barely think about anymore. The interface is clean and the tracking is real-time, so I can glance at my site’s performance and get back to work."

Koen Kanters

Senior Software Engineer at ASML

"Pulsetic is easy-to-use and simple to get started. As an agency, I like that it includes unlimited status pages, because I can create one for each of my clients. Pulsetic includes every alert channel that I want, and advanced settings that give me greater confidence in the uptime. I can require that a response include certain text and respond within a certain timeframe in order for a site to be considered online. This gives me assurance that we would be notified if there were major performance issues or a bad deployment that made the site unusable. These features come with every paid plan, so our monthly bill is predictable. The API is a huge bonus on the teams plan. We have used it to add maintenance windows for certain monitors automatically based on events that happen in other software we use."

FAQ: TCP Port Monitoring

What is TCP port monitoring, and why is it important?

It's how you keep tabs on specific Transmission Control Protocol (TCP) ports: are they reachable, and how fast do they answer? The services sitting behind those ports, web servers and databases for instance, only work if the port is up and responsive, so watching the port tells you whether the service is healthy.

How does TCP port monitoring work?

The monitor opens a connection to the port you've named and times how long the handshake takes. No answer, or a sluggish one? That's the signal something's wrong, and you get flagged.

What's the best way to monitor TCP ports for uptime and performance?

Let an automated service do the checking on a schedule rather than poking ports by hand. It runs the checks for you and pings you the moment something fails or starts to slow down.

What issues can TCP port monitoring detect?

Plenty. Outright outages, firewall rules that block the wrong thing, servers buckling under load, connections that drop midstream. Any of these can take your system offline, and the monitor catches them.

Can TCP port monitoring help identify slow connections?

Yes. Every check records how long the port took to respond, so a connection that's dragging shows up in the numbers. From there your admins can dig into the cause and tune the network.

What types of services benefit from TCP port monitoring?

Web servers, databases, email and FTP servers, the list goes on. If an application talks over a TCP connection, keeping an eye on its port pays off.

How does TCP monitoring integrate with alerting systems?

Most services plug straight into the channels your team already watches: Slack, email, SMS, webhooks. When a problem turns up, the alert lands where you'll actually see it.
