Monitoring Linux And Unix Server Temperatures With Opsview

Monitoring Linux And Unix Server Temperatures With Opsview

Managing power consumption in a Datacenter is a key factor in helping keep overall business energy costs down and ensuring servers are running at optimum performance. Overheating can lead to increased costs for cooling and also runs the risk of servers crashing.  Opsview server monitoring software can be used to check and alert on server temperature and also the temperature of individual components within a server (Memory, CPU and Hard drives). Thresholds and alerts can be set for when critical temperatures are exceeded, helping to keep hot-running servers in check. This blog post details how to configure Opsview to monitor the temperature of Linux and Unix servers.
