Hardware Sentry monitors the health of your servers hardware within BMC Software® PATROL®. It's a KM for PATROL: it needs to be installed on each managed server with a PATROL Agent, and then you can check the hardware components of your servers from any PATROL Console. The operators will be alerted as soon as a hardware failure is detected somewhere in your IT infrastructure. It's greater and easier than any other hardware monitoring solution available on the market: with the same module, you can monitor the hardware of almost any server. Great server coverage and easy integration!
