There are a variety of potential problems your network may experience over time. MxToolbox offers a free TCP lookup tool and monitoring to alert you when you have a problem with critical services (such as POP, LDAP, IMAP). The first step to fixing a problem with those critical services is identifying which problem your network is currently experiencing by running a TCP Port Status Check.

Once you know which network problem(s) your critical services are encountering, you can easily add a tcp monitor to alert you if your critical services go down.

Tests we run include:

Benefits to TCP Monitoring:

Each TCP monitor runs multiple tests against your network every day
Monitors alert you instantly when you have a network performance issue
