3rd Party Server Monitor with Insight Mg

Does anyone know of a utility that can graph (or log somehow) the internal temps of Compaq servers using the measurement that Insight Manager reports? We have a farm of servers in a very small room that doesn’t get very good ventilation and we are concerned about the temperature of the boxes during the weekend when the AC isn’t on. CIM can give you the real-time temp, but not any past info. Compaq doesn’t know of anything that can do this. TIA
