Thoughts would really depend on your hardware specs. Most air coming out of a server should be around 75-80. If your internal room temp is about 64 you might be lucky and get that. It also depends on "where" your airflow is coming from, ceiling or floor and where you have you vented tiles located. Air flow distribution is the biggest thing to worry about before you can even start to think about where to place your probes.
If you setup your room(s) correctly then monitoring your center overall is best and can get even better if your server hardware can send traps if the temp is too high. So I guess what I am trying to say if your air flow distribution is correct the rest will fall into place. m2c Tv -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Syed Ali Sent: Tuesday, March 04, 2003 11:59 AM To: [EMAIL PROTECTED] Subject: [mrtg] Re: Monitoring APC UPS temp Since we are talking about temperature, any suggestions on which place is best in a data center for temperature and humidity probes? Some options that I can think of are: 1. in front of servers (all my servers take in care from the front and push it out of the back) 2. in back of servers 3. away from the servers With #1 I can get an estimate of the temp and humidity of the air intake for the servers. With #2 I can get an estimate of the temp and humidity of the air being output by the servers. With #3 I can get an estimate of the general temp and humidity in the data center. Any thoughts? -----Original Message----- From: Jerry Heidtke [mailto:[EMAIL PROTECTED] Sent: Monday, March 03, 2003 10:17 PM To: 'Sameh Ahmed'; [EMAIL PROTECTED] Subject: [mrtg] Re: Monitoring APC UPS temp Remove the # from in front of Options[DEVICE_NAME_batt-temp]. This needs to be specified as a gauge. Otherwise, mrtg tries to calculate a rate of degrees per second, which you surely don't want.
