On-Premise Poller for Linux

On-Premise Poller helps monitor your internal network and resources like URLs and network devices behind a firewall. Thus you can keep track of the resources behind the virtual private network (VPN). This software is near zero maintenance and firewall friendly and can be considered as a private monitoring station complementing Site24x7's 100+ global monitoring locations. To monitor your website transactions using a real browser monitor, you can set up a private monitoring location using our Linux flavored On-Premise Poller. The service name is Site24x7 On-Premise Poller service. Learn more about our On-Premise Poller architecture.
