Getting information from System Report

@mhuppert there is an Extension Attribute template that will pull Battery Health Status. Just create a new EA, click the "New from Template" button, and find the Battery entries.

Once you have that, you can scope an Smart Group to that EA and set it to email on change of the group.

There are several Extension Attribute templates that you can use to collect and report battery info e.g. Battery Cycle Count.

You can also look at "Determining battery cycle count for Mac notebooks" for more info on that.

Hi. I suggest going into your JSS under Computer Management > Management Framework > Extension Attributes. Choose "New From Template" and scroll down to the System Information section. There are 9 template EAs you can add for all kinds of battery monitoring. Examples:

• Battery Charge Percentage
• Battery Charging
• Battery Cycle Count
• Battery Fully Charged
• Battery Health Status
• Battery Installed
• Battery Manufacturer
• Battery Serial Number
• Battery Time Remaining

I'm sure one of those, or several, will help out. The one that I think you're looking for is the "Battery Health Status"

Edit: What everyone else said before me!

Thank you for all of your responses.

I got the group set up for the extension attribute of Battery Health Status. the problem is that the template script will look for a specific item value of 1 or 0. 1 will return a "Failure" and a 0 will return an "OK". All of the computers are coming back as OK. That means that "Service Battery" does not mean "Failed Battery" (to the system). In other words, we are close but no cigar.

Any other ideas on how to glean this information from the computers through JSS?

BTW, a Google search was not productive in finding any additional information.

Thanks again.

If it makes a difference, I forgot to mention that these computers are running OS 10.9.5.

Thanks.

Just an FYI, its a bit faster to get the model name of the Mac from either ioreg or sysctl, rather than using system_profiler. I tend to only use system_profiler in scripts when there is no other choice, just because its a little sluggish. In the case of sysctl, its also easier in addition to being faster.

## Using ioreg
$ ioreg -rd1 -c IOPlatformExpertDevice | awk -F'"' '/model/{print $4}'
$ MacBookPro11,1

## Using sysctl
$ sysctl hw.model | awk '{print $NF}'
$ MacBookPro11,1

You can then use that with a 'like' comparison in the script, as in:

if [[ "$model" =~ "Book" ]]; then

since all Mac laptops have the word "Book" in them, whereas desktop models do not.

Thanks bpavlov, that script worked!

I just wanted to post these here to follow up on @mm2270 suggestion.

#!/bin/bash

#Determine model
model=$(ioreg -rd1 -c IOPlatformExpertDevice | awk -F'"' '/model/{print $4}')

if [[ "$model" =~ "Book" ]]; then

#Determine Battery Cycle Count
result=$(ioreg -r -c "AppleSmartBattery" | grep -w "CycleCount" | awk '{print $3}' | sed s/"//g)
    echo "<result>$result</result>"
else
    echo "<result>Not A MacBook</result>"
fi

#!/bin/bash

#Determine model
model=$(ioreg -rd1 -c IOPlatformExpertDevice | awk -F'"' '/model/{print $4}')

if [[ "$model" =~ "Book" ]]; then

#Determine Battery Serial Number
result=$(ioreg -r -c "AppleSmartBattery" | grep "BatterySerialNumber" | awk '{print $3}' | sed s/"//g)
    echo "<result>$result</result>"
else
    echo "<result>Not A MacBook</result>"
fi

This may be a Catalina thing, or a MacPro 16" thing, but parsing the Cycle Count using ioreg now includes the next line of info, which I don't want. Suggestions on stripping out the cruft?

# Display battery cycle count
runCommand=$( /usr/sbin/ioreg -r -c "AppleSmartBattery" | /usr/bin/grep -w "CycleCount" | /usr/bin/awk '{print $3}' | /usr/bin/sed s/"//g )
batteryCycleCount="Battery Cycle Count: $runCommand"

Results:

3
{StateOfCharge=97,PMUConfigured=0,Voltage=12691,QmaxCell1=9323,AdapterPower=1107761963,SystemPower=1108040831,ResScale=244,QmaxCell2=9352,QmaxCell0=9325,CycleCount=3,DesignCapacity=8790}

Never mind, my Google-Fu finally kicked in...

This command gives me just what I want, the numerical value only:

system_profiler SPPowerDataType | grep "Cycle Count" | awk '{print $3}'

There are now a second line that matches '-w "CycleCount"', that is why you get the CycleCount value (3 in your case) twice.

I think what you are looking for is just the 'BatteryData', so using '-w BatteryData' in the grep (or drop the grep and use "/usr/bin/awk '/BatteryData/ {print $3}'" would be to your liking.
