Until now, IP sensors were limited to SNMP request-response communication over a local-area network (LAN). However, this was a major obstacle for GSM/GPRS communication. In the HTTP-based HWg-Push protocol, active communication is initiated by the sensor. The HWg-Push protocol addresses the needs and security of today's networks. Individual IP sensors can be located in separate firewalled networks, and the sensors actively connect to a central server. HWg-Push Nagios collector is a Nagios application for collecting data from IP sensors. Up to hundreds of IP sensors can connect to the central Nagios server and submit their data. The HWg-Push Nagios collector app then collects these data and passes them to the Nagios monitoring system.
Sensor monitoring in Nagios over LAN and GSM/GPRS
HW group introduces its new HWg-Push Nagios collector – a simple way of connecting LAN and GSM/GPRS sensors to Nagios-based monitoring systems. For a system integrator, this means reduced costs for monitoring moving sites or sites that are difficult to connect to a standard LAN. Moreover, remote monitoring of technology and equipment can be easily offered as a service – GSM sensors can monitor any premises anywhere.
