MonitLab performs ICMP request monitoring (PING), TCP port checks, UDP port checks, FTP checks and SSH checks.
Network connectivity monitoring (PING checks)
PING checks are a standard way to check the network connectivty to any internet-connected device.
Not only does MonitLab use them to establish connectivity status (working / not working), but it collects performance information on each check (measuring network packet loss and response times).
As a means of overcoming false positives, as well as provoding more thorough results, we perform such checks from multiple locations and collect the data from each one.
No matter if you're using our website monitoring services or not, setting up a PING check for any website/server is a great idea.
TCP port checks
If you have an online service that runs on a given TCP network port, you can make sure it's working by using MonitLab's TCP port monitoring services.
Just specify a host:port pair and let MonitLab check connectivity, as well as performance (response times) for your service.
Additionally, you can specify some data to send to that port and the response you wish to receive. Set that up and have MonitLab watch that not only is your service alive on that port, but it's also servicing requests in an expected manner.
UDP port checks
Just like TCP ports above, we can monitor connectivity using the UDP network protocol.
Just specify a host:port pair and the data to send/receive and let MonitLab check connectivity, perform request/response verification, as well as collect performance data (response times) for your service.
FTP server checks
An FTP server can be checked using the TCP port check (discussed above) or using our dedicated FTP server check.
Just give MonitLab a host:port pair and it will make sure your FTP server is alive and speaking the FTP protocol.
SSH server checks
An SSH server can be checked using the TCP port check (discussed above) or using our dedicated SSH server check.
Just give MonitLab a host:port pair and it will make sure your SSH server is alive and speaking the SSH protocol.
