In their own words
DNS Check
DNS Check monitors DNS records and name servers for changes, lookup failures and troubleshooting issues. Automated checks run every five minutes on all plans, with one-click rechecks, record history and shareable read-only reports. The checker compares entered records with DNS responses and can flag unresponsive name servers, missing or duplicate records and invalid SPF records. Fourteen record types are supported, including A, AAAA, ALIAS, CAA, CNAME, HTTPS, MX, NS, PTR, SOA, SPF, SRV, SVCB and TXT. Notifications can use email, PagerDuty and Slack on all plans, with listed integrations including Basecamp, Jira Service Management, Nagios, OpsGenie, Pingdom and Splunk On-Call. The REST API returns JSON, uses API keys and is available to every account for individual records or groups. Basic is free for 10 records and seven days of history. Professional costs $8 a month, or $80 yearly, for 100 records and 90 days. Higher plans cover up to 3,000 records; more requires a quote.
Nagios XI
Nagios XI monitors servers, network devices, applications and services from a Linux server you manage. It checks configured thresholds, records results and sends notifications. Standard includes more than 90 configuration wizards, auto-discovery, dashboards, performance graphs, an open REST API, automation, configuration rollback and snapshots. Enterprise adds SLA and capacity-planning reports, scheduled reports and pages, business process intelligence, bulk changes and an audit log. Users can be restricted to assigned host and service groups, with authentication options including Active Directory or LDAP over SSL, Microsoft Entra ID single sign-on and Duo two-factor authentication. It is self-hosted on Linux, with virtual machine images for several hypervisors and offline installation on Red Hat and CentOS Stream. A 30-day trial provides unlimited monitoring, Enterprise features and direct support without a credit card. The free plan is limited to 7 nodes or 100 services, whichever comes first. Paid perpetual licenses are priced by monitored nodes: Standard is $2,595.00 once and Enterprise is $4,690.00 once, each shown for 100 nodes.
