The part I was missing was using the subclass FileAttachment. doh

Yep, having the EmailAttachment class as an abstract class means it cannot be instantiated. Gotta use the public child classes.

All the parts work now. Once I get the code cleaned up, I will post it here.

Need to make sure I bookmark the javadocs. I think I recall seeing them before but forgot all about them. heh

1. get the full path to your attachment.

var toAttach = "/opt/mango/overrides/web/modules/mangoUI/web/ui/manifest.json";    
    var emailAttachment = new com.serotonin.web.mail.EmailAttachment.FileAttachment("manifest.json",toAttach);

First parameter is the name of the file that will appear in the email. This means if your attachment hasa really bizarre name or is timestamped to oblivion you can make it "Easier to read".

NEXT:
When you generate the email content object, simply call the in class method for attaching a file:

emailContent.addAttachment(EmailAttachment ea )

//simply generate and append
var emailContent = new com.serotonin.web.mail.EmailContent(null, writer.toString(), com.serotonin.m2m2.Common.UTF8);
emailContent.addAttachment(emailAttachment);

THEN!

com.serotonin.m2m2.rt.maint.work.EmailWorkItem.queueEmail(recipientsArray, "Email with attached file", emailContent, null); //FIRE!

Et voila!

EDIT:

@phildunlap are there any javadocs?

Here is the link @phildunlap provided we practically posted this within a few minutes of each other :D
https://github.com/infiniteautomation/ma-core-public/blob/main/Core/src/com/serotonin/web/mail

This will be hugely beneficial for other mango users.

So far so good. Using the examples you provided, I am able to query the data points I want for the last hour of samples and save the data to a csv file on the server.

The email example works fine but I'm stuck trying to attach the csv file to the email. I haven't been able to find any javadocs or api docs for the Serotonin classes and my experiments haven't worked yet. Hopefully I haven't been blind. heh

Do you have any examples of attaching a file?

@phildunlap are there any javadocs?

Thanks for the starting points. As I pick through the requirements for the csv and email, it looks like the scripting data source is the more likely option. Will let you know how things go.

Ian

and for the RQL query: (I grossly simplified mine)

var allPoints = DataPointQuery.query("and(like(deviceName,My Device*),eq(name,probe1))&sort(deviceName,name)&limit(10000)");

Then simply iterate through all of the points:

for (var k = 0; k < allPoints.length; k+=1) {
    //do magic here
    
}```

The existing Excel scheduled report function would work fine if it was able to be generated as a csv instead of a xlsx. The csv report would be emailed as an attachment to the client.

I guess the next question would be: what is the best way to generate a csv report containing multiple data points for a specific time period?

Seeing the script you used would be interesting. At least gives me some insight as to how to create my own queries.

Thanks
Ian
