@Nurr it is possible that you are seeing a rendered value which makes it look like there was a difference of 0.01 but if you look at the raw data you might find the difference to be slightly larger and being rounded by the TextRenderer on that point. Just a thought, the logging in your scenario works like I said about.

@Nurr never mind about the timestamps. You are using "Interval logging and point value changes". This type of logging will log every 5 minutes AND when the value changes.

@Nurr what type of data source is this? It could be from restarting the data point (or source). Also can you get the exact timestamps of the values?

@Ricardo there is some information here as to how to use iptables. I suggest you familiarize yourself with how they work as they are useful to redirect port I/O between privileged ports and non-privileged ports.

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

The user is tpacker with only the user role:

Excel Report Permissions:

Menu Item Permissions:

@dage I just tested this on our latest codebase and it works fine. This could be a bug in beta.3 but I doubt it so I suggest you review your permissions again and make sure your menu item permissions aren't set too restrictive. Not sure what else to tell you as it works in my tests just fine.

@cmusselm that setting may help depending on what you are doing. That setting will effectively send a short value to a register if it is 2 bytes according to the point locator's modbus data type. If it is > 2 bytes then no matter what it will send an array to the slave and likely will write > 1 register.

@dage your images are misleading as they show that you can see the report template? Note that each template has its own permissions:

Read generated report - which lets a user view the generated report
and
Edit report template - which lets a user edit the report template

Both of those in your 2nd image do not have the user role assigned to them.
