Hi,
You can create collections inside HP SIM with a treshold on certain values that get trespassed... Like for instance the temperature... And on that event collection you can create a task to send you a mail...
You can use also any other SNMP tool that can read the SNMP values of the temperature sensors through the ILO and create alert mails based on those ones too...
Used both already at customer sites...
