V4 will give you the option is increase the number of threads used for starting data sources. You may also want to think about using MySQL for a system that size. But to answer your question I don't see anything abnormal with that starting time.

Interestingly i have just tested it out and it seems that there is some kind of a rounding thing coming up with values being exactly the threshold value. If value changes next fraction of the threshold then this does not happen.

A quick test

Create a virtual point with exact settings

Current value 1
Set point to 1.01
No logging
Set point back to 1.0
Set point to 1.011
Logging appears

If going to other way around

Current value 1.01
Set point to 1.00
Logging appears

I am guessing datalogging does not happen if new value is greater than current value in the defined threshold but if new value is lower then current value in the defined threshold then logging works correctly.

I might also fish out an idea that @Nurr polling time is related to the issue (I guess it might be once per minute?) where the cached value is the new over threshold limit but it does not get logged but still triggers a reset for interval logging and then it has been the same for 5 minutes and then it gets logged by the interval logging sequence.

But still even though this happens, interval logging still works in my instance so I guess this information is not actually so relevant.

Hi @chrapchp

I believe there is a bug in the module, please try enabling auto-reconnect this may work around the bug for now.

Hi @Nurr

The mango edge devices use IDrive. However, this is not really related to Mango and you can use the service you are familiar with. Basically, you just need to copy the backup folder to a safe storage location regularly.

@CraigWeb thanks. we got this error, when the device is offline on the site. As a result, we successfully get the data with OPC DA.

Anytime

@oru_david
this known issue. patch could be coming soon.

Are you running as administrator?
I wonder if that will influence anything...

The underlying Java library for generating Excel reports isn't great on memory usage, if you are generating too large of an excel file it can crash Mango. I would suggest you try running that report over a very small time range to see if that helps.

@mitchb6 said in Mango 3.7.7 free version will not start:

Caused by: java.lang.NoClassDefFoundError: jdk/nashorn/api/scripting/ClassFilter

The version/flavor of Java you are using doesn't have the nashorn scripting classes (which are required for Mango). We are working to migrate away from that but Mango 4.0.0 will still have this dependency too.

@dage here are some screenshots proving it works on the latest (un-released) Mango 4.0.0-SNAPSHOT
