SSH check monitors the availability of SSH services that you have open to internet access. As is known, SSH (Secure Shell) is an encrypted access protocol that makes the data transmission secure. SSH check, not only tests whether the port you specify is up or down but also performs a true ssh login to the corresponding server. You can set up your success criteria for your monitor after you select the parameters such as Monitoring address, SSH port (default ssh port is 22) and monitoring frequency for controlling SSH service. These criteria are;

• Success of SSH connection
• The response time (delay) is below a certain amount of time

After you select success criteria, you can also select failure criteria with data rule. The options are;

• Assume downtime, if any of the probe results are unsuccessful.
• Assume downtime, if all of the probe results are unsuccessful.
• Assume downtime, a specific ratio of the probe results are unsuccessful.

These selections allow you to choose how sensitive the measurements are to the fault. By selecting the following alarm criteria after the data rule, you can receive alarm notifications when there is an degredaton in performance that does not meet your defined success criteria. The alarm criteria are as follows:

• Alarm is active
• Notify if measurement is unsuccesful for a number of measurement periods
• Notify when the monitor is successful again
• Refresh alarm at a specific period of time

You can select the users you want to be notified whan an alarm occur, and then decide how you want to receive the notifications. Notification options include;

• Email
• webhook
• slack
• twitter DM
• Push notification (mobile applications)
