Cluster Check

Allow me to introduce our newest check type, Cluster.

The Cluster check allows you to group interdependent NodePing checks in order to get notifications and track availability of the group of checks as a whole. You specify a threshold of how many of those checks must be passing in order for the cluster to be considered ‘up’. If the number of those checks passing drops below your configured threshold, the cluster check will fail and send the configured notifications.

We use it to keep an eye on our Cassandra servers but you can use it for any logical group of services that are interdependent. Some other use cases:

  • DNS services – monitor each DNS server with DNS checks and then a cluster check on those DNS checks to get that very important alert when all DNS servers are offline!
  • Web servers – monitor the backend web servers behind your reverse proxy or load balancer to make sure you have enough of them available to handle the traffic.
  • SMTP – monitor your SMTP checks and know that there’s always at least one server available to receive email for your domains.

Cluster checks are available to all NodePing plans today. If you’re not using NodePing yet, please sign up for our 15-day, free trial today.

WHOIS Monitoring

Need an alert when your domain is about to expire?

Want to make sure your domain admin contact hasn’t been tampered with?

Need a notification when your configured name servers get changed?

Maybe you’re running your own TLD (you lucky dog, you) and need to verify your WHOIS servers are up and responding properly?

NodePing’s new WHOIS monitoring has got you covered. Our new check will verify the presence or absence in the WHOIS response for any text you specify, helping you ensure your domain information hasn’t been hacked or altered without you knowing.  We’ll also send alerts before the domain expires. You choose how many days ahead of expiration you want to receive the notifications and how you want to be notified (email, SMS, Voice call, Pushover, Slack, etc)

You can optionally configure a specific WHOIS server to query via IPv4 or IPv6.

WHOIS checks are available to all NodePing accounts starting today. If you don’t have an account yet, sign up for your free, 15-day trial today and let NodePing keep an eye on your WHOIS info for you.

Support for Multiple Public Status Pages

Our public status report is a critical part of keeping your customers informed of your site and service status—which after all is one of the points of monitoring. Our status pages are customizable to your company, and support a custom domain so you can display your status at status.yourdomain.com, or whatever is most applicable to your business.

We have had a public status page as one of our key features for some time.  Now, we’re adding support for multiple status pages on one account. For instance, NodePing has a status report page for our websites at status.nodeping.com, and one specifically for our probe servers at probestatus.nodeping.com.  Business and Provider accounts can optionally set up an SSL cert for their status pages (contact support for info how).

To create a new status report, just log into your account , and go to the “Account Settings” tab, then the “Reporting” subtab. Click “Add new status report” and add as many checks as you want to your new status report.  

We hope you will find this feature just as useful as we do.  We also have several more enhancements for public status pages coming soon.  Let us know what you think at support@nodeping.com, by posting comments here, or by using our Contact Page.
