Ok thanks for your advice. I will look at your suggestion. Thanks once again

Have you read https://docs-v3.mango-os.com/about-mango-java-script ? Look at Statistical objects section. Hint, there is a delta in statistical object.

var pointValues = myContextPoint.getPointValuesBetween(fromTimestampInMilliseconds,toTimestampInMilliseconds); print(pointValues); Fox

@nurr Can you guide me on how to do that

@mattfox Ok thanks for that information. Will do that. best regards Ramhuzaini

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.

Hi @ramhuzaini You can use a maintenance event, it can be either bound to a data source and all its points or just a subset of points. There is an option to schedule it or toggle it manually.

@ralf Thanks for your help

Ok. it works. Thank you very much

Hi Ramhuzani I see how that message can be misleading. You will need to look in your ma.log file to see what error you are getting. If you go to system settings --> email settings you can confirm your SMTP server setting and test it from there. Then have a look at your ma.log file to see if it is an authentication failure or host failer etc. Note that it will send a test email to the email address of the user logged in. So you will need to make sure your user has an email address.

Hi everyone, Thank you for all the advice. The information is very helpful. Best regards Ramhuzaini

@ramhuzaini Were you able to connect to OPC servers on local machine? I am exploring mango and just can't see OPC servers installed locally on my PC. The server dropdown remains empty, which I assume should get filled with all registered OPC servers. Will appreciate any tips on how to correctly configure an OPC DA source in mango.
