What is the Best Way to Monitor Server Temperature?
Solution 1:
If you were running Linux
For CPU and board:
lm_sensors + NetMRG or Nagios
For disks:
hddtemp or smartctl (smartmontools) + NetMRG or Nagios
Since you are running Windows, speedfan may be of some use.
Solution 2:
Usually, server hardware will have temperature sensors pollable via IPMI. This is true back to all the servers I have, even generic brands, to about 2002... and is also true for my home PC.
On linux, you can access this information using the ipmitool
. Some servers also expose it to snmp
if you have the appropriate MIB for your vendor. Servers without an ipmi interface may expose the data through lm_sensors
.
On windows, you can use the ipmiutil project to access ipmi information... there are a variety of other ways to do it, and I'm not a windows admin so I can't tell you for sure what the best way is, but you might consider running the windows version of NRPE to provide secure access to the data for nagios.
Solution 3:
Nagios and Zenoss are both extensible enough that you should be able to implement temperature monitoring easily, and they're both free.
If you want to be really simple just write a script that uses the lm_sensors tools and emails the answer, then schedule it with cron. Really, that's only a good course of action if you have just a couple of servers, but it is quick and easy to manage.
Depending on your servers there may be tools with them, or you can use SNMP too. I know the Dell PowerEdge's come with the web based servertools to alert on this sort of thing.
