I'm trying to setup some basic temperature monitoring on my server - (without using third-party tools).
I've installed a couple of libraries on my linux box to get sensors working on my server, and now I can use the sensors command which might return data like the following:
asb100-i2c-1-2d
Adapter: SMBus nForce2 adapter at 5500
in0: +1.79 V (min = +1.39 V, max = +2.08 V)
in1: +1.79 V (min = +1.39 V, max = +2.08 V)
in2: +3.34 V (min = +2.96 V, max = +3.63 V)
in3: +2.96 V (min = +2.67 V, max = +3.28 V)
in4: +3.06 V (min = +2.51 V, max = +3.79 V)
in5: +3.06 V (min = +0.00 V, max = +0.00 V)
in6: +3.04 V (min = +0.00 V, max = +0.00 V)
fan1: 6136 RPM (min = 2777 RPM, div = 2)
fan2: 0 RPM (min = 3534 RPM, div = 2)
fan3: 0 RPM (min = 10714 RPM, div = 2)
temp1: +37.0°C (high = +80.0°C, hyst = +75.0°C)
temp2: +26.5°C (high = +80.0°C, hyst = +75.0°C)
temp3: -0.5°C (high = +80.0°C, hyst = +75.0°C)
temp4: +25.0°C (high = +80.0°C, hyst = +75.0°C)
cpu0_vid: +1.750 V
w83l785ts-i2c-1-2e
Adapter: SMBus nForce2 adapter at 5500
temp1: +30.0°C (high = +85.0°C)
I then realised I could narrow it down easily by adding | grep temp onto the end of the command, so I tried running sensors | grep temp, and got this:
temp1: +37.0°C (high = +80.0°C, hyst = +75.0°C)
temp2: +26.5°C (high = +80.0°C, hyst = +75.0°C)
temp3: -0.5°C (high = +80.0°C, hyst = +75.0°C)
temp4: +25.0°C (high = +80.0°C, hyst = +75.0°C)
temp1: +30.0°C (high = +85.0°C)
I realised that temp3 clearly wasn't functioning correctly, so I revised my command to eliminate that result: sensors | grep temp[1,2,4]
temp1: +36.0°C (high = +80.0°C, hyst = +75.0°C)
temp2: +26.5°C (high = +80.0°C, hyst = +75.0°C)
temp4: +25.0°C (high = +80.0°C, hyst = +75.0°C)
temp1: +30.0°C (high = +85.0°C)
Now I want to trim it right down, so all I have is a comma-separated string, which might look like this.
+36.0,+26.5,+25.0,+30.0
I can then set this up to submit this data to a server every 5/10 minutes.
How can I achieve this using grep or other commands?
