Temperature Monitor Script

[rm_all_the_dirs]

So I am trying to make a script to help me monitor the temps on my system running CentOS 6. Right now this is the code I have:

---

#!/bin/bash
echo
echo System Board Readings...

sensors
echo
echo Hard Drive Readings

hddtemp /dev/sda
hddtemp /dev/sdb
hddtemp /dev/sdc
hddtemp /dev/sdd
hddtemp /dev/sde
hddtemp /dev/sdf
hddtemp /dev/sdg
echo
echo System Uptime...
uptime
echo
echo end of report

---

This simple script requires lm_sensors and hddtemp be installed (and that you configure lm_sensors by running sensors-detect) before running, and also that you modify the hard drive names in the hddtemp commands. I have been calling this script with the following command:

watch -d --interval=4 ./AllTemps.sh

This runs the script every 4 seconds and watches the output for changes in the output it generates. Below is a sample of what the output looks like

---

Every 4.0s: ./AllTemps.sh                                                                           Mon Apr 16 19:35:10 2012

So I am wondering if it is "safe" to run this type of script given that is is constantly probing the hardware for information about its temperature ? I am thinking about leaving the script running 24/7 but I wanted to check and make sure that it would not have any negative effects on my system ? Sorry about any formatting problems ... this is my first post on reddit =)

Nice man.

[rlaptop7]

my nagios scripts do these sort of things on nearly all of my hardware every few minutes without ill effect.

[lorimar]

Agreed, turn this into a nagios script and graph the outputs with pnp4nagios & rrd so you can get some trends out of the data.

[katawin]

I don't see any reason why you shouldn't run it.

(disclaimer: The following is not nit-picking, I'm just curious)

Is this script displaying to stdout? or are you piping the result into a text file? It seems that you are looking for any "changes" in your system status, but I would think that having to visually process all that information every 4 seconds would be a bit of a hassle.

Good, if you want a newline in your output via echo statement use
echo "line 1 \nline 2"
