Sync-udelement not working since move to IIS

Alc · January 9, 2020, 12:37pm

Hi all,

I have the following code in dashboard.ps1

$endpoint2 = New-UDEndpoint -Schedule $Schedule1 -Id sql -Endpoint {
    Sync-UDElement -id 'appservercolumn2' -Broadcast
    Sync-UDElement -id 'appservercolumn4' -Broadcast
}

Then in my page.ps1

New-UDColumn -id 'appservercolumn2' -size 2 -Endpoint {
            New-UDCard -id 'appservercolumn2card' -TextAlignment center -Endpoint {
                $oldest = $cache:appservergrid2 | Sort-Object 'Last Change' | Select-Object -First 1
                $duration = (Get-Date) - $oldest.'Last Change'
                
                $running = $cache:appservergrid2 | Where-Object { $_.State -eq "RUNNING" }
				
				if ([math]::ceiling($duration.TotalMinutes) -ge 60){ 
				$oldest = 60} else { $oldest = [math]::ceiling($duration.TotalMinutes) }
                
				New-UDGauge -PaddingVertical 8 -Width 250 -id 'AppServerActiveServers' -MaxValue 15 -NeedleColor white -StartColor green -EndColor red -value ($cache:appserverobject.'Active Servers') -Segments 3 -ValueText $('Total servers: ' + $($cache:appserverobject.'Active Servers'))
				New-UDGauge -PaddingVertical 8 -Width 250 -id 'AppServerRunningServers' -MaxValue 15 -NeedleColor white -StartColor green -EndColor red -value (@($running).count)  -Segments 3 -ValueText $('Running servers: ' + $(@($running).count))
                New-UDGauge -PaddingVertical 8 -Width 250 -id 'AppServerOldestChange' -MaxValue 60 -NeedleColor white -StartColor green -EndColor red -value $oldest -Segments 6 -ValueText $('Oldest change: ' + $([string]$([math]::ceiling($duration.TotalMinutes)) + ' mins'))
            }
        }

The page loads fine initially - the guages are shown as expected, however when the schedule runs, the elements disappear from the screen. Chrome console shows the following:

I have also tried syncing the card but I get 404’s on refresh with this too. It’s worth noting that before I moved over to IIS, it was working fine.

Any ideas?

Many thanks

I don’t see a New-UDElement anywhere in your code, is that somewhere else? I have an IIS site and i am using Set-UDElement successfully.

Alc · January 9, 2020, 1:11pm

As far as I am aware, you don’t have to use new-udelement as long as it is a control which uses the -endpoint param then it should work.

BoSen29 · January 9, 2020, 2:51pm

Hi @Alc
did you follow the guide on
https://docs.universaldashboard.io/webserver/running-dashboards/iis

Sounds like you forgot to install the websocket feature?

psDevUK · January 9, 2020, 5:29pm

Hello @Alc, I’m using the gauge control to, and there is no need to sync the element, I see you got it in an endpoint, and pretty sure if you scrub your sync element bits, and literally use the -AutoRefresh parameter on the endpoint holding your gauge components then they will automatically be refreshed…You did also include this custom component in the endpointinitilization script bit so that they can be used in an endpoint yeah?

Alc · January 10, 2020, 10:05am

@BoSen29 websocket is enabled

@psDevUK from looking it seems I can only use autorefresh on the column? I’ve just tried it and found something strange. I set it to refreshinterval 1 to test. Here’s a video of what happens: 2020 01 10 09 31 27 - Gifyu (sorry it’s quite big so takes a while to load - watch to the end to see the oddity).

I’ve uploaded the log file here: https://floobits.com/PoshCode/PowerShell.Slack.com/file/log.txt

Hmmm no I haven’t done this. How do you include a component in there? I’ve used it to bring in all my modules containing my functions but this is not used in this case.

I have uploaded my dashboard here: GitHub - paulharman/dashboard the page in question is under pages\page4.ps1

Big thanks to everyone.

psDevUK · January 10, 2020, 10:45am

I will attempt to put a demo of how to do this on my github script pages…As I am using the gauge on a complaints dashboard which goes up everytime you raise a complaint which works without issues…but have a look at this link https://psdevuk.github.io/ud-flix/Animated-Number-Counter/
Then scroll near the bottom for the bit that says

More Dynamic

Then look at my script New-UDEndpointInitialization -Module and how I import the module to be used within endpoints throughout my dashboard.

Alc · January 10, 2020, 11:26am

Will try and get my head around it.

Not sure if I misunderstand but I don’t see an autorefresh parameter on new-udgauge, so is new-udcolumn where it should go?

Just noticed something else going strange in the diagnostics page - look how many endpoints and sessions there are!

each of these unnamed endpoints relate to this code:

New-UDColumn -id 'appservercolumn2' -size 2 -Endpoint {
            New-UDCard -id 'appservercolumn2card' -TextAlignment center -Endpoint {
                $oldest = $cache:appservergrid2 | Sort-Object 'Last Change' | Select-Object -First 1
                $duration = (Get-Date) - $oldest.'Last Change'
                
                $running = $cache:appservergrid2 | Where-Object { $_.State -eq "RUNNING" }
				
				if ([math]::ceiling($duration.TotalMinutes) -ge 60){ 
				$oldest = 60} else { $oldest = [math]::ceiling($duration.TotalMinutes) }
                
				New-UDGauge -PaddingVertical 8 -Width 250 -id 'AppServerActiveServers' -MaxValue 15 -NeedleColor white -StartColor green -EndColor red -value ($cache:appserverobject.'Active Servers') -Segments 3 -ValueText $('Total servers: ' + $($cache:appserverobject.'Active Servers'))
				New-UDGauge -PaddingVertical 8 -Width 250 -id 'AppServerRunningServers' -MaxValue 15 -NeedleColor white -StartColor green -EndColor red -value (@($running).count)  -Segments 3 -ValueText $('Running servers: ' + $(@($running).count))
                New-UDGauge -PaddingVertical 8 -Width 250 -id 'AppServerOldestChange' -MaxValue 60 -NeedleColor white -StartColor green -EndColor red -value $oldest -Segments 6 -ValueText $('Oldest change: ' + $([string]$([math]::ceiling($duration.TotalMinutes)) + ' mins'))
            }
        }

@adam any idea why it would be creating so many endpoints and why they would be unique using guid rather than id as per my code?

adam · January 11, 2020, 10:45pm

When you expand the endpoints in the diagnotsics view, is it one of the endpoints in your example in this post? I see IDs on all of you components so I’m surprised you have so many endpoints with GUID ids.

Alc · January 11, 2020, 11:36pm

They are all the code above - New-UDColumn -id ‘appservercolumn2’

adam · January 11, 2020, 11:38pm

And those are just within a New-UDRow?

Alc · January 12, 2020, 5:53pm

Yes - code here: https://github.com/paulharman/dashboard/blob/master/pages/page4.ps1

adam · January 13, 2020, 3:33pm

Ok. Thanks! That’s helpful. Checking it out.

Alc · January 17, 2020, 9:20am

Can’t get to the bottom of this one. Resorting to a chrome plugin to automatically refresh the page at the moment

Jacob-Evans · January 21, 2020, 1:53pm

You know New-UDPage has -RefreshInterval to auto refresh the page? You don’t need to use a chrome plugin.

Alc · January 21, 2020, 4:34pm

Hi, yeah I do, but this would affect all users of the dashboard rather than just the one running on our tv screen in the office

Alc · January 28, 2020, 9:32am

Hi, does anyone have any ideas about this please?

BoSen29 · January 28, 2020, 9:54am

Hi @Alc

Could you verify Sync-UDElement working in a simpler implementation?

IE:


 New-UDElement -Id "SyncMe" -Tag span -Endpoint {
     New-UDHtml -Markup Get-Random
 }
 New-UDButton -Text "Update" -OnClick {
     Sync-UDElement -Id "SyncMe"
 }

As this might be a bug with either:
Sync-UDElement in scheduled endpoints
Broadcast parameter
UDGauge (probably not)
