Description

Number Of Network Probes

USD 1.5 per 10,000 probes

Daily

A network probe is counted each time a probe node performs a protocol check on a monitoring target, such as a domain name or an IP address. A probe is billed regardless of whether the check succeeds or fails.

Number Of Text Message Alerts

USD 0.225 per message

Daily

If you configure text message alerts, an alert message is sent to the specified contact when an alert event occurs. You are charged for each successfully sent text message.

Cost estimation example

Assume that you enable DNS resolution monitoring for www.example.com.

The following NS addresses are configured for the domain name:

  • vip1.alidns.com

  • vip2.alidns.com

Enabled metrics:

  • Consistency monitoring of resolution results from authoritative DNS servers against the expected results (all NS addresses are probed)

  • Consistency monitoring of resolution results from the local carrier of the probe node against the expected results

Probe frequency: 1 probe/minute

Probe nodes: China Mobile - Beijing, China Mobile - Shanghai

The estimated total number of network probes per month is: (2 authoritative DNS probes + 1 local carrier probe) × 2 nodes × 1 probe/minute × 60 minutes/hour × 24 hours/day × 30 days/month = 259,200 probes.

The estimated total number of text message alerts per month: If 1 alert is generated per day, the total number of text message alerts per month is 1 message/day × 30 days/month = 30 messages.

Estimated total cost: Probe fees + Text message alert fees (if any) = USD 38.88 + USD 6.75 = USD 45.63.
