PRTG API to Power BI - Historic Data

Good Morning,

Sorry if this has been asked before but I have been unable to find a relevant answer. I am using PowerBI to query the PRTG API. This has been simple in terms of getting all sensors an account can see, but less obvious for getting bulk historic data.

What I want is to be able to grab historic data for all sensors relevant to the account, and be able to identify which sensor that data is associated with. Currently I only end up with a lot of data with information on which sensor it belongs to.

Is there a property that can be added to the historic data API call to return the object ID or sensor name?

This is what I have done so far: -

  • Grab all the sensors for the account created with
  • /api/table.json?content=sensors&columns=objid,group,device,sensor,status,message,lastvalue
  • Navigate and Expand the list to get the record data.
  • Convert this to a table.
  • Expand the json values into columns.
  • Add a new column combining the URL and ID together to create an full URL for historic data.
  • /api/historicdata.json?id=" & Text.From([objid]) & "&avg=0&sdate=2018-11-02-00-00-00&edate=2018-11-02-23-59-59&usecaption=1)
  • Add a custom column with the contents of the URL
  • Convert this to a table
  • Create a new column based on the JSON output from the URL
  • data = List.Transform(#"Renamed Columns"[objecturl], each Json.Document(Web.Contents(_))),
  • Convert this to a table
  • Expand this column a few times to get the histdata as seperate columns.

Unfortunately I only see datatime, loading time, bytes received, download bandwidth, time to first byte and coverage - with no way to relate these back to the original object ID.

Hi Chris,

What works for me is to set up a daily scheduled task on my PRTG server to run a powershell script. This script exports the historic data that I need from PRTG, sorts through it, formats it and exports it as a .csv. I then can pick up the csv file with Power BI and use the data to create a dashboard.

I have posted my code below. Let me know if this helps or if you have any further questions. PRTGAPI by lordmilko is a must have if you're working with the API and powershell. https://github.com/lordmilko/PrtgAPI

Hello Chris,

Thank you very much for your question.

I don't see an approach to achieve this via the API. The possibilities for the historic data export via PRTG's API can be found under 'Setup | PRTG API | Historic Data' (corresponding manual article).

You might also check if Historic Data Reports might help to query the data as required. Additionally, please see this kb thread, as it also refers to Power BI even though it does not really provide you with the solution.

Please excuse that I am not able to provide you with a more satisfactory answer here.

Best regards,
Sebastian

Thanks for your reply, Matthew.

Since writing the initial request, I did manage to achieve this solely through Power BI.
With any luck, it will help others. Also, there may well be other ways to achieve the same result. I also admit this has not yet been optimised or tidied up!

Looks like the code formatting option broke on my two posts - hopefully Sebastian can correct that as there should be numbered lines ;)

Hi Chris,

The formatting should now be fixed ;)

Best regards

Hi, I've edited the script provided by Matthew but I can't find out how to change the date period; for example how can I set the daily report for the past month?

Thanks in advance.

Hi dl_infra,

The line to look at is the following

$reportcsv = Request-PRTGSensorHistoricData -ID $s.id -Days 1 -datemodifier $i

-datemodifier = how many days ago

    $i = 0
    do
    {
        $i++

        Write-Host "Obtaining Report..."
	    $reportcsv = Request-PRTGSensorHistoricData -ID $s.id -Days 1 -datemodifier $i
	    $dtresults = $($reportcsv | select "Downtime(RAW)")
	    $dt = 0
	    foreach($r in $dtresults)
	    {
		    $dt += $r.'Downtime(RAW)'
	    }
	    $Uptime = [math]::Round(100 - ($dt / ($dtresults.Count - 1)),2)
        $report = [PSCustomObject]@{
		    "Site" = $group
		    "Category" = $type
		    "Device" = $s.Device
		    "Uptime" = $Uptime
            "Date" = $((Get-Date).AddDays(-$i).ToString("dd-MM-yyyy"))
	    }
        $routerswitchUptimeReport += $report
        $report
    }
    until($i -eq 7)

This code with the last line "until($i -eq 7)" gets the report once per day for 7 days.

Alternatively...

You can modify the following code to specifiy start and end dates and set "until($i -eq 1)" This would return one line to the CSV per sensor rather than 7

$edate = (Get-Date).AddDays(-$datemodifier+1).ToString("yyyy-MM-dd")
$sdate = (Get-Date).AddDays(-$datemodifier).ToString("yyyy-MM-dd")
$url = "https://$PRTGHost/api/historicdata.csv?id=$ID&avg=3600&sdate=$sdate-05-00-00&edate=$edate-00-00-00&$auth"

Note: my script only returns data from between 5am till midnight

Hope that helps. If you need further help post your code and let me know where you are stuck.

Matthew

Hi Matthew, thanks for the quick reply.

Thanks to your suggestion I'm able to change the report period.

I'm now looking a method to always create a report for the past month so I can schedule it without change anytime the parameters.

Is that possible?

Thanks

Yes completely possible.

Change the line

$reportcsv = Request-PRTGSensorHistoricData -ID $s.id -Days 1 -datemodifier $i

to

$reportcsv = Request-PRTGSensorHistoricData  -ID $s.id

and change the function Request-PRTGSensorHistoricData from

function Request-PRTGSensorHistoricData
{
    Param (
        [Parameter(Position=0,Mandatory=$True)]
        [ValidateNotNullorEmpty()]
        [int]$ID,
		[int]$days,
		[int]$datemodifier
    )

    try
    {
        $edate = (Get-Date).AddDays(-$datemodifier+1).ToString("yyyy-MM-dd")
        $sdate = (Get-Date).AddDays(-$datemodifier).ToString("yyyy-MM-dd")
        $url = "https://$PRTGHost/api/historicdata.csv?id=$ID&avg=3600&sdate=$sdate-05-00-00&edate=$edate-00-00-00&$auth"
        $request = Invoke-WebRequest -Uri $url -MaximumRedirection 0 -ErrorAction Ignore
        convertFrom-csv ($request)
    }
    catch
    {
    
    }
}

to

function Request-PRTGSensorHistoricData
{
    Param (
        [Parameter(Position=0,Mandatory=$True)]
        [ValidateNotNullorEmpty()]
        [int]$ID
    )

    try
    {
        $edate = (Get-Date).AddDays(-1).ToString("yyyy-MM-dd")
        $sdate = (Get-Date).AddMonths(-1).ToString("yyyy-MM-dd")
        $url = "https://$PRTGHost/api/historicdata.csv?id=$ID&avg=3600&sdate=$sdate-00-00-00&edate=$edate-23-59-59&$auth"
        $request = Invoke-WebRequest -Uri $url -MaximumRedirection 0 -ErrorAction Ignore
        convertFrom-csv ($request)
    }
    catch
    {
    
    }
}

You can then use windows task scheduler to schedule it to run on the 1st of every month and it will report on the previous month.

Hi Matthew, sorry for the late reply.

I've changed the code lines as indicated by you and it works perfectly.

Thanks a lot
