Is there a way to display the content of a file on a map ?

Hello,

I am looking for a way to get the content of an txt File displayed on a map. The content of the file gets refreshed every 5 minutes.

A script-sensor doesn’t work for me, for every "new" line of data a new channel is created and the channel from a line that got replaced just gets a "no value" message instead of being deleted. In addition to that, I couldn´t find a way to sort the channels by their Value, from high to low.

This is the script I used

Write-output '<?xml version="1.0" encoding="Windows-1252" ?>'

Write-output '<prtg>'

$InputData = @(Get-Content C:\folder\file.txt)
foreach ($line in $inputData) {
$lineName = $line.SubString(3)
$lineNumber = $line.SubString(0,2)

Write-output '   <result>'
$channel ='      <channel>' + $lineName + '</channel>'
$value ="      <value>"+ $lineNumber + "</value>"
echo $channel
echo $value
Write-output '   </result>'
}

echo '   <text>Demo values. OS: %OS%^</text>'
echo '</prtg>'

My next approach was to display the whole TXT file with a Custom-HTML-Object here is what I tried:

(The "file.txt" is located on the PRTG-Server himself)

<iframe src='file://PRTGserver/c$/folder/file.txt'></iframe>

If I try to access file:PRTGserver/c$/folder/file.txt manually with a web-browser, it works great. I also tried to use "localhost" and the IP-Address. But in all three cases it doesn´t work with the Custom-HTML-Object.

Then I made the folder a network share with read permissions for everyone. I could verify that the network share worked as intended by opening the file from my own PC (with Web browser of cause). But again, it didn’t work with the Custom-HTML-Sensor. <iframe src='file://PRTGserver/folder/file.txt'></iframe>

Does someone either has another idea how I could display the file content or know what I must change to make my approaches work ?

Best regards, More

Hello,

Thank you for your post.

One way that may work is to use the script sensor, and have the text from the file appear in the sensor message instead of the channels. Then you can use a "Sensor (message only)" map object (from the "Status Icons" group) to display the entire sensor message.

Hello, thanks for the response. I did as you said and wrote the value to the channel message, looks good so far. But now I struggle to change the font size of my custom "only-message-sensor".

I read in the forms that I must use

style="font-size:48px"

to change the font size but wherever I tried to paste it in it wouldn’t work ...

This is the sensor-code:

!--Status Icons: Sensor message only-->
<div class="map_object map_icon2 map_icon_large mapicon_status_transparent" id="<@itemid>" objectid="<@objectid>" subid="<@subid>" style="<#mapobject type="coordinates" subid="<@subid>" mode="<@editmode>">
  <#mapobject type="objectgrip" mode="<@editmode>">
  <#mapobject type="htmlbefore" subid="<@subid>">
  <#checkobjecttype objecttype="sensor" nicemessage="true" id="<@objectid>">

  <div style="clear: both;"><#objectstatus name="message" show="textraw" id="<@objectid>"></div>

  <#mapobject type="htmlafter" subid="<@subid>">
</div>

Hi,

unfortunately, the solution mentioned in this article doesn´t work for me.

i tried adding .customalarms_biggerfont td { font-size: 30px !important; }

to the styles_custom.css (which was blank)

This is the Sensor Code I used:

<!--Status Icons: Sensor message only-->
<div class="map_object map_icon2 map_icon_large mapicon_status_transparent customalarms_biggerfont" id="<@itemid>" objectid="<@objectid>" subid="<@subid>" style="<#mapobject type="coordinates" subid="<@subid>" mode="<@editmode>">">
  <#mapobject type="objectgrip" mode="<@editmode>">
  <#mapobject type="htmlbefore" subid="<@subid>">
  <#checkobjecttype objecttype="sensor" nicemessage="true" id="<@objectid>">

  <div style="clear: both;"><#objectstatus name="message" show="textraw" id="<@objectid>" ></div>

  <#mapobject type="htmlafter" subid="<@subid>">
</div>

I also tried adding .customalarms_biggerfont td { font-size: 30px !important; }

to the styles_custom_v2.css, which I already use to customize the color of another Sensor

but this change also didn´t have any effect. Even a Server restart, which was required to make the color change take effect back then, didn´t help.

Any idea what’s wrong?

I have looked into this a bit further, and it seems that you can't increase the font for map objects that have a fixed size. This does work for map object for which you can change the size (like for the "Data Tables" objects).

Hello,

I'm afraid that the map editor is a little bit limited regarding this matter. Nevertheless, I found an other KB article which may help you: https://kb.paessler.com/en/topic/62000-values-only-on-maps

I'm afraid that we can't provide further support for advanced customizations.

Kind regards.
