Safeguard the Stability of your Website and Applications

We know you have better things to do than double checking and triple checking your network or web performance. Let Sonar do the hard work for you. Our monitoring nodes can verify performance as soon as every two minutes and alert you of any changes before your clients notice.

Sonar checks are fully integrated with Constellix DNS. That means you can configure web checks in Sonar to influence DNS failover and load balancing decisions... automatically!

HTTP Check

HTTP (Hypertext Transfer Protocol) checks are also known as “header” checks and status code checks. This is one of the most commonly used checks for web developers and designers. You can use this check to make sure your web server is responding.

  • Monitor domain availability and load times.
  • Schedule maintenance windows, so you're not alerted when you don't need to be.
  • Check for IPv6 connectivity with the click of a button.
  • Over 90 monitoring nodes to choose from.
Web Check

HTTPS Check

Keep your domain secure

HTTPS checks or SSL checkers can help you verify your SSL certificate if you just added SSL or HTTPS certificate to your domain.

If you recently added an SSL certificate to your domain, we recommended creating a CAA record.

Waterfall Check

Great for Web Designers and Developers

Waterfall checks make it easy to see exactly which assets and resources are affecting page-load performance. Each waterfall check is configurable by location so you can monitor domains from multiple vantage points around the world and see how your end-users are loading your site resources such as:

  • Document load (DOM)
  • CSS
  • Images
  • CSS Images
  • Javascript
  • Favicon

Web Check

TCP Check

A TCP Check, also known as a port check, allows you to verify connectivity of a hostname across various port and protocols. TCP, or Transfer Control Protocol, is one of the main protocols used to exchange information over the Internet –specifically for application programs.

Historical Traceroute

Traceroutes show you every hop between your browser and the hostname you want to connect to. You can also compare your current traceroute with past traceroutes result to identify: changes in network latency, packet loss, and bottlenecks in your traffic.

Instant Check

Instant Checks

Your new daily network troubleshooting utility.

Run basic monitoring checks for free within the Constellix Sonar dashboard. You can even run a check and then a traceroute without leaving the page. We took the same tools you've known and loved from our mobile monitoring app, Sonar Lite, and put in your browser.

  • HTTP and HTTPS check
  • TCP check
  • DNS check (A, AAAA, CNAME, SOA, NS, etc.)
  • Traceroute

Each check can be run from dozens of nodes within the Constellix network. You can even run a check through one location and then quickly check a different location, all without having to reenter your information.

DNS Check

There are two types of DNS checks. The first allows you to query a Resolving name server of your choice for an expected response when you input an FQDN (Fully Qualified Domain Name).

The second kind of DNS check is included in the free Instant Check feature. This kind of DNS check lets you query a specific record for an expected response.
