Powershell Custom Sensors and Time

Hello Gerald,

Thank you for your message.

Regarding what you would like to achieve, I'm afraid that it's not possible to configure the channel to display all decimal during its creation. Nevertheless, you can override that parameter in the channel settings, by enabling the option Custom under Decimal Places and provide the value "2" there.

Here is also an updated version of the script:

$lastscan = Get-Date -Format "yyyy/MM/dd HH:mm:ss"						# Time Now
$midNight = Get-Date -Hour 0 -Minute 00 -Format "yyyy/MM/dd HH:mm:ss"	# Midnight
$timeDiff = new-timespan -start $midNight -end $lastscan				# Calc diff as Structure of Times
[string]$timeDiffS = ([string]$timeDiff.hours).PadLeft(2,'0') + '.' + ([string]$timeDiff.minutes).PadLeft(2,'0')

Write-output @"
{
    "prtg": {
        "result": [
            {
                "channel": "Time of Last Scan",
                "value": "$timeDiffS",
                "float": "1"
            }
        ],
        "text": "$timeDiff"
    }
}
"@

The latter provide the possibility to return information in the sensor message field via the key "text".

If you have questions, let us know.

Regards.

Isnt that what "decimalmode": "2.2",' does, in my script?

re Text

There are 32 other channels in this sensor and the text attribute doesnt work as it doesnt show up on my Map which looks like this:

Downtime

And i would like to suppress the Downtime channel in my map, but this doesnt work (if i do it manually it does, so i am guessing i have the wrong ID for the channel?)

Write-Host ' {' Write-Host ' "channel": "Downtime",' Write-Host ' "showChart": "0",' Write-Host ' "showTable": "0",' Write-Host ' }'

Hello Gerald,

The setting DecimalMode allows to choose between the option "auto" and "all" only. The latter is the default option when float is set to 1 however it automatically remove the trailing 0. Therefore, the only option is to manually configure the channel setting Decimal Places to "Custom" with the value set to 2.

If you have to change the setting for all channels, I invite you to have a look at the PowerShell module PRTGAPI to modify them all at once. Here is the wiki of the module: https://github.com/lordmilko/PrtgAPI/wiki

Here is the command you can use for it:

Get-Sensor -id SensorID | get-channel | Set-ChannelProperty -DecimalMode Custom -DecimalPlaces 2

Regarding the downtime channel, it is not possible to "remove" it at the creation of the sensor. However, you can hide it from the table and graph when the sensor is created, as you noticed.

If you have further questions, let me know.

Regards.
