Ensure seamless network connectivity with Applications Manager’s TCP monitor
The hyper-connected environments that run today’s IT infrastructure need high availability and connectivity. Whether it’s a web server, database, or any custom application listening on a TCP port, uninterrupted communication is critical. ManageEngine Applications Manager’s TCP Monitor offers a simple yet powerful way to keep tabs on these network connections and detect issues before they escalate.
What is a TCP monitor?
A TCP monitor is a solution that verifies the availability of a TCP/IP service. The TCP monitor in Applications Manager provides a clear view of your port availability and responsiveness by periodically attempting to connect to a specific IP address and port combination. If the connection fails or takes too long, the system raises an alert, helping admin teams take immediate corrective actions.
Why is monitoring TCP ports necessary?
Applications often depend on TCP-based services, like HTTP (port 80), HTTPS (443), SMTP (25), or custom services hosted on arbitrary ports. Downtime or delays in these services result in application failures, revenue loss, and bad user experience. With TCP monitoring, you can:
Detect outages the moment they occur
Verify port accessibility from specific network locations
Ensure third-party services your app depends on are running and reachable
Measure response times to identify latency issues
Key features of a TCP monitor
Here are the key features you should look for in a TCP monitor:
Custom port monitoring: Monitor any port on any host in your network.
Response time tracking: Get insights into how long it takes to establish the TCP handshake.
Threshold-based alerts: Set response time thresholds and get notified if the connection exceeds them.
Downtime reports: Access historical data on availability and performance for trend analysis.
Root cause analysis: Combine TCP monitoring with other monitors (like DNS, HTTP, or process monitors) for a more holistic view.
How to set up a TCP monitor in Applications Manager
It takes less than a minute to set up a TCP monitor for your ports in Applications Manager. Here’s all that you will have to do:
Click on Add Monitor and select TCP Monitor
Enter the Hostname/IP and Port Number you want to monitor
Configure polling intervals and thresholds for response time
Set alert actions like email, SMS, and automated scripts
Save and track availability via the dashboard and reports
