DNS availability and record monitoring
Detect resolution failures and slow responses before they interrupt websites, mail or application traffic. RMON queries the resolver and record type you rely on.
Verify DNS resolution from the networks your users depend on
RMON lets you choose the resolver and query the required record type. The check reports resolution failures and response time; it does not compare returned record values with an expected IP address or text.
Run checks from several monitoring locations to uncover resolver-specific or regional problems. Response time, current state and history help distinguish a temporary delay from a persistent failure.
Catch missing records
Alert when a required DNS record cannot be resolved from the selected resolver.
Detect slow resolution
Measure DNS response time and set a threshold for slow replies.
Find regional differences
Repeat the check from multiple locations and compare the observed result.
What this solution can cover
- A, CAA, CNAME, MX, NS, PTR, SRV and TXT checks
- Configurable DNS resolver
- DNS response-time measurement
- Retries and warning thresholds
- Multi-location assignment
- Failure and recovery notifications
Monitor a DNS record in four steps
- 01
Choose a resolver
Select the DNS server whose view of the record you need to verify.
- 02
Select the record
Enter the domain name, record type and resolver port.
- 03
Assign locations
Run the query from the agents or regions that represent real users.
- 04
Set alerts
Choose retries, timing thresholds and notification channels.
Common questions about dns record monitoring
Which DNS records can RMON check?
RMON supports common record types including A, CAA, CNAME, MX, NS, PTR, SRV and TXT.
Can I choose the DNS resolver?
Yes. Each DNS check can query the resolver that is relevant to the service or location.
Does RMON measure DNS response time?
Yes. DNS check results include response timing that can be used with alert thresholds.
