First, you want to log into the Constellix control panel through the Sonar application. If you are already logged into another Constellix application, use the menu button in the top left corner to switch to the Sonar application.
From the dashboard, click “Add Check” in the top right corner and choose the kind of check you want to create.
There are four different kinds of checks you can create: web, TCP, DNS and RUM. In this example, we will create a web check to monitor the IP addresses of our web servers.
A. Name: Make sure you use a really specific name for your checks. For example, if we want to create a check for a web server in Europe, we might want to name it EU Web Server. This comes in handy later when you start applying checks to your DNS records.
B. Version: This specifies whether the check is with IPv4 or IPv6. By default, this is set at IPv4.
C. Protocol: Specifies whether the check is over HTTP or HTTPS. These settings are specific for web checks.
D. Host: Specify the endpoint for your check. An endpoint can be an IP address or FQDN (Fully Qualified Domain Name).
E. Port: Enter the port to check through.
F. Interval: This tells our systems how often to run the check from every 30 seconds to once a day.
G. Interval Policy: Specify if you would like your check to be run simultaneously from all of your selected locations, or if you would like to run the check once per selected location or region in a round robin fashion.
H. Verification Policy: For a Simple check, when a monitoring node detects an endpoint as down, we will also check from a nearby location. This helps rule out any false positives. You can also choose a Majority verification policy, which will use half of your available monitoring locations to verify that an endpoint is infact down before alerting you.
I. Check Regions: Regions and locations from which to run the check.
J. Contact Groups: Pick and choose which group(s) of contacts to alert.
K. Notification Report: Specify the expiration time of the notification report which is included in UP/DOWN alerts.
