NodePing, website and server monitoring service, offers the NodePing API that enables IT departments to incorporate NodePing functionality into third party apps and existing maintenance and monitoring tools. Every minute, NodePing sends messages to a variety of services and protocols (e.g. SSL, HTTP, IMAP4, DNS, etc.) to ensure a site or server remains up and running. If NodePing receives an error, users can identify an unlimited amount of contacts to receive alerts via email, text, voice, Twitter, webhook, and more.
