hostnag vs Site24x7

Site24x7 is the full suite from Zoho: website, DNS, SSL, domain, mail round-trip, blocklist and heartbeat monitors from 130+ locations, beside server, network, APM, RUM and log monitoring, with an On-Premise Poller for the inside of a network and MSP plans. The same rows on one timeline without the suite: no collector, no per-monitor licence arithmetic, and a free tier for five hosts.

What Site24x7 has that we don't

Server, network, APM, RUM and log monitoring in the same product, with an On-Premise Poller for the inside of a network.
A mail round-trip monitor that sends a message and reads it back, and an RBL monitor for IPs.
OCSP revocation and blocklisted-CA checks on certificates, 130+ locations and checks down to 10 seconds.

Switching

01List your monitors from the Site24x7 API; each is one row.
02Put them in a CSV with at least the columns type and target (name, interval, port, keyword, expected_status and record_type are optional; the import dialog links a template) and upload it in the import dialog.
03Website monitors become http, port monitors tcp, DNS server monitors dns with their record_type, SSL/TLS certificate monitors tls_cert, Domain Expiry monitors domain_registration; heartbeat monitors become heartbeats with a new hostnag ping URL to point the job at.
04Ping (ICMP) monitors carry over as Ping monitors, run from hostnag's own probes.
05RBL monitors become a mail monitor on the domain, which checks its MX addresses against four zones daily; server, network, APM, RUM and mail round-trip monitors have no counterpart in hostnag.
06Check intervals snap up to the nearest hostnag preset (1, 5, 15, 60, 360 or 1440 minutes).
07Monitors are created up to your plan's limit; the rest stay listed in the preview so nothing is lost silently.
