Monitoring Documentation

Access to Monitoring

Monitoring checks are an optional feature. By default, there is a Free Monitoring plan, which includes one Monitoring check. 

Supported monitoring options

Monitoring checks are supported both for any IPv4 or IPv6 address. Each check can be configured separately, which means that the Monitoring check is compatible with Web services, Mail services, DNS services, etc.

Available monitoring types

Currently, our Monitoring checks system supports following monitoring types:

    • ICMP Ping - The system sends 12 ICMP ping checks to the given IP address. The packets are 4x 64bytes, 4x 512bytes, and 4x 1024bytes.
      • Ping with 15% threshold - If 15% or more of the packets fails, the check is marked as DOWN.
      • Ping with 25% threshold - If 25% or more of the packets fails, the check is marked as DOWN.
      • Ping with 50% threshold - If 50% or more of the packets fails, the check is marked as DOWN.
    • Web checks - The system makes HTTP(S) request to the given IP address. The hostname, port, and path can be customized.
      • HTTP - Check request is send over HTTP. If the request time outs or the returned response code is not 200, the check is marked as DOWN.
      • HTTPS - Check request is send over HTTPS. If the request time outs or the returned response code is not 200, the check is marked as DOWN.
      • HTTP with custom string in the response - Check request is send over HTTP. If the request time outs or the returned response code is not 200, or the returned response text is not equal to the defined custom string, the check is marked as DOWN.
      • HTTPS with custom string in the response - Check request is send over HTTPS. If the request time outs or the returned response code is not 200, or the returned response text is not equal to the defined custom string, the check is marked as DOWN.
    • TCP - The system makes TCP connection to the given IP address on the chosen port number. If the connection is unsuccessful, the check is marked as DOWN.
    • UDP - The system scans the chosen UDP port number on the given IP address. If the connection is unsuccessful, the check is marked as DOWN.
    • DNS - The system makes DNS query for chosen hostname and query type on the given IP address. If the response is not equal to the expected response, the check is marked as DOWN. Please, note, the IPv6 monitored servers must be added as extended IPv6 addresses with your AAAA records in your DNS zone. The compressed IPv6 form may cause a false downtime alert.
Compressed IPv6 Sample Expanded IPv6 Sample
2A06:FB00:1::1:96. 2A06:FB00:0001:0000:0000:0000:0001:0096.

Monitoring regions

You can use the monitoring regions to configure your records to be monitored only from a specific area. Here are the options:

  • Global - this is the default option, it sets your IP address to be monitored from all nodes globally.
  • Europe - your IP address will be monitored only from nodes located in Europe.
  • North America - your IP address will be monitored only from nodes located in North America (USA and Canada).

Monitoring regions are great options if you are runing GeoDNS and you want to monitor your nodes from the closest locations.

History

For each Monitoring check, we are recording history for the executed checks. The history is stored for a specific period of time, according to your plan.

Activation and deactivation

To activate a Monitoring check all you need to do is click on "Add new" button on your Dashboard in section "Monitoring" and configure the desired Monitoring check as required.
