🤔 Problems with trend chart warnings (ApiServlet)

[Maser]

I am working on a dashboard for data presentation, in one of them I am placing two trend charts with the following configuration.

After a while of feeding the graph sending the data from node-network to Groov Server the graphs remain with a warning symbol.

After about 5 min of feeding the graph sending the data from node-network to Groov Server the graphs are frozen with warning symbol.

These are the errors I get in my logs

7/6/2022 23:05:42	ApiServlet	An exception occurred while handling /api/v0/data-logging/fetch-interactive

What platform are you running on? Is this an EPIC system, or groov Server for Windows, or…?

Shot in the dark: how much free disk space is available on the system that groov View is running on?

[Maser]

@Jonathan_Fischer is groov Server for Windows, I have free space on disk 352GB.

Can you please go into build mode and click on Configure → Devices and Tags.
From there, highlight the controller/device that the tag is coming from and take a look at the Device Health.
I’m wondering if you are seeing some network issues between the GS4W and the edge device.

Here is example of one of my PAC R controllers that has a ton of trend data in my groov View.

[Jonathan_Fischer]

If I understand what he’s saying, he’s using Node-RED to populate a Data Store in groov View, and then trending that. There won’t be a device health thing to look at in that case.

Take a look in C:\Program Files(x86)\Opto22\groov\logged-data: there should be two directories in there named classic and interactive, and the interactive one at least should have files in it. Is there anything in there?

@Maser

feeding the graph sending the data from node-network to Groov Server

You might be right. I took what he said to be an edge node device somewhere on his network.

@Maser can you explain your setup a bit better please?

[Maser]

@Jonathan_Fischer , Checking the information if I have files in the directory.

[Maser]

@Beno,
This is what I am doing to test between Groov server and Node-red

This is the scheme I am working on. Groov Server and Node-Red are on the same computer. Disregard MQTT at this point I am simulating random values.

@Jonathan_Fischer, @Beno

I have identified the following behavior on the logged-data folder. When saving after making a change in the build mode the graphics restarts and the files in the folder are these:

After the graph fails only the following files would be there, the other initial files are gone.

[Jonathan_Fischer]

We’ll probably want to have you contact product support at this point. It’d help to get a look at your logs, and possibly your project to see what’s going on.

Sorry,

I have cleaned up all the pages that I am not using as well as the tags that I may have deleted. I have only left what I am actually using and I think that has solved the problem.

Thank you very much for your support.
