Hi CoraDias, welcome to the forum! It's not ideal to resurrect threads if it's not really related to the thread. Yes the MangoES will display the command line over the HDMI port. I believe this thread involved a kiosk type display, so he installed other packages on his ES. What IP issue was in this thread?

I couldn't say for sure. I would advise sorting that top window by memory (shift+f, arrows to mem, press 's'). You could experiment with removing the Xms parameter. Sometimes with larger heaps the garbage collector can be lazy, and then when it does run it has more work to do and a bigger pile of potential garbage to sift through, but I wouldn't expect that to cause what you're describing, as it also generally has more garbage it can collect, and it can meet its targets easily

It looks like you also deleted /opt/mango/ftl You could copy this directory from a complete Mango

Nvm, found it! var columnGraphs = event.chart.graphs.filter(function(graph) { return graph.type === 'column' && graph.ownColumns; }); var redrawNeeded = false; columnGraphs.forEach(function(graph) { var newWidth = Math.floor(graph.width / graph.ownColumns.length * 0.8); if (chart.categoryAxis.equalSpacing) { newWidth = undefined; } if (newWidth !== graph.fixedColumnWidth) { graph.fixedColumnWidth = newWidth; redrawNeeded = true; } }); if (redrawNeeded){ chart.validateNow(); }

@CraigWeb Hi, Craig Good to see you back on here. I will definitely submit this for my project since I have an existing Mango system running. Should I just get in contact with technical support?

Nevermind on that last post... all the test classes which compile correctly can be found in the source archive: bacnet4J-src.zip which can be found here: http://sourceforge.net/projects/bacnet4j/files/bacnet4j/1.2/ The are not in bacnet4j.jar or seroUtils.jar I would still love to know the basic design of this package or a good description of the LocalDevice and RemoteDevice classes...

Modbus/RTU Modbus/TCP My company (greenHouse Gas and Electric) supports j2mod which also has support for Modbus/UDP (Modbus/TCP packets over UDP), but I don't personally use Modbus/UDP. I mention j2mod because j2mod is being used as the "base" for posting open source Arduino sketches that support Modbus/RTU and eventually Modbus/TCP and/or Modbus/UDP. I'd like to do more with 1-wire, just haven't had the time. I'm toying with creating new protocols, but there are intellectual property issues to resolve.

It is done by the built-in process, done in the upgrade shell script. Also, that doesn't feel to me like an error that would be caused by a stale JSP. Jfree charts renders everything on the server and returns only an image, and look how nestled the call stack is into the JFree code. I don't rule it out, though.

Very true. The community definitely makes me take a closer look at many things, which I enjoy. Virtual points can be useful to check if your meta point is behaving as you expect. The blue help icon (?) in sections with scripts has a 'related item' called 'Mango JavaScript' that documents the functions a data point has. Examples are definitely spread around the forum as well. There's a whole section called 'Scripting general discussion'

Anytime, that's what we're (the forum) here for.

Hi phildunlap, I use a simple USB A male to B male cable to connect my Arduino and unfortunately I am not capable of building 485 type of connection. Any type of timing settings (even above 10 s) resulted in aborted polls in Mango, while as strict polling as 500 ms or 1 s in ScadaBR or RapidSCADA or any other Modbus Master (downloaded some applications acting as Modbus Master) do not act like Mango with the same settings. Therefore, I do not know what type of timing override I might employ to make it work.

what is required in "db.mysqldump" and "db.mysql" fileds? The path to invoke the mysqldump or mysql programs (or just the executables if they're on the Mango user's $Path). The error, backupMysqlWithOutDatabase:442) - java.io.IOException: Cannot run program "mysqldump" Indicates mysqldump is not on the path. what's the problem and how to solve it? That issue appears to have been solved in version 3.1.3 of the excel reports module. You will probably needs to work around it by manually deleting from the excelReports table and deleting from Mango/web/modules/excelReports/web/report-data/ as appropriate. It may only be one report with a null filename, you could perhaps investigate the excelReports SQL table to see.

I used that function because it will give a java.util.List which we could addAll to the other list acquired the same way. You could also use the lastValue function, as described in the JavaScript help, or simply use the .value and .time from the point (which actually wouldn't work quite right here because we need to go through the text renderer, and a .value is a primitive data type usually instead of a DataValue object.

Thanks for your time on this Joel, it's great to get a resolution and have the reports running again. Cheers Dan

I don't think that's a question that anyone here can answer. It could be noise on your network or something else. Joel.

I recently raised a support ticket for this - please disregard the Support Ticket - we applied this fix to the enterprise mango and the problem seems to have gone . We also applied this to the maintenance events table. I think during our upgrade from H2 -> MySQL this problem occurred. Thankyou for your help and suggestions for getting this problem fixed.

Nothing is returned from the subscribe function, so the command you have stopped on wouldn't have anything to print. Because the JavaScript in a browser executes in a single threaded way, the onmessage function couldn't log anything if execution is paused.

Hi Terry, That last Data Source seems to have fixed the crashing. How do I remove the added debug messages from the logs? I have removed the line from the log4j configuration file and restarted Mango but the messages keep coming. I am getting daily logs over 650MB in size. Cheers, Matt.

This forum is for discussions around the Modbus4J product, which is used in Mango, but otherwise no associated. It is possible to get Mango to act as a modbus slave, but not trivial. If you need this, please use the contact page to request a quote.

Glad to hear you got it resolved!
