Uptime and server monitoring with one-minute checks, status pages and blacklist monitoring. Free for 15 uptime monitors.
About HetrixTools
HetrixTools is a web-based monitoring service for websites, servers, IP addresses and domains. It runs uptime checks every minute from up to 12 locations and reports an outage only when most of those locations agree. Its server monitoring uses an installable agent, and its blacklist monitor checks IPs and domains against major blacklists, including Microsoft SNDS. Results can be shared on public status pages and sent through alert channels.
The homepage lists free tiers of 15 uptime monitors and 32 blacklist monitors. Phone calls and SMS alerts use credits, sub-accounts require a paid plan, and the server agent must be installed on each monitored machine.
