      Which did you do? You probably would have to have had done one of the last two, I doubt the first two work in this case.

      tail -n 30 /opt/mango/logs/ma.log

      This will always kill Mango (and any other Java processes running): kill -9 $(pidof java); (edit: okay, it won't kill a process in D sleep)

      This will start Mango with both stdout and stderr coming back to the command line, if you think Mango is having trouble starting: sudo /opt/mango/bin/ma.sh start

          Upload your entire ma.log file. I also provided steps for trying again on a clean setup.

              Hi Arvand,

              No but I just changed something that might fix it. Can you try again?

                    Should i attempt to upgrade before trying clean?

                      I do not see Timer Already Cancelled errors in your log after you restarted Mango.

                          You ran out of memory using a large excel report. Are you using rollups? You should probably be watching the console output while you're developing your solution.

                            i dont understand. what i was developing is that simple httpget, unless that javascript load issue is causing issues up again.

                                thanks. i deleted it and it worked. Now i see the httpget running. but the issue is that it runs only the first time (when i enable the datasource). My update period is set to 2 min but i dont see the time stamp for the virtual DP to be ever updated after that initial enable toggle button clicked, Thanks.

                                  ok, just to be exact, it does seem that it actualy updates the DP but it doesnt do it every 2 minutes. I left it since the last post and I see the value time stamp is 13:50.

                                    ok, so the problem was that the virtual data point was set to update every 10 min and the httpget was 2 minutes. I changed virtual dp to 2 min and now its working as expected. Thanks for the help :)

                                        Hi,
                                        Its been a while but i'm encountering a new issue that is very related to what we discussed here before. I developed the code and everything was working fine in the test box and i left it for few months. Didn't pay much attention until now.
                                        I have an HTTP Retriever that calls a local url (my file is in /opt/mango/web). This url, reads bunch of XIDs and then does some calculations and then sets bunch of other XIDs.
                                        My HTTP Retriever runs fine with no error (set on update every 2 minutes and I see it under Polls) but my values dont get updated. Its as if the code is not running. I dont see any errors in ma.log and so far i coudln't see any indication of an issue. Even when i enable/disable the data source, i still dont see the data being updated (in ma.log, i see the data source being disabled/enabled with no issue).
                                        To test the url for the http retriever, i manually ran it in a browser and it actually updated the values but if i do "curl" from the mango command prompt, i dont see the values being updated.
                                        Where can i see the actual result from HTTP Retriever, is there a log for it? Thanks.

                                          Hi arvand,

                                          It doesn't look like there's more logging to be enabled. Be sure to keep an eye on your events, as I would expect an event to be raised in Mango if there was an error. It's possible an error is escaping to stderr, but I wouldn't think so. You can launch Mango manually with /opt/mango/bin/ma.sh start and then trigger a poll to see if there's an exception escaping.

                                          More likely than not, if the checkmark on the data source fetches the data (unless your browser has some authenticating cookie), it's going to be a problem with a point of some kind. If you've made recent edits, I would try disabling those points, or all but one, and trying again.

                                          I do not know what you mean, "but if I do curl from the mango command prompt." I don't refer to anything as the Mango command prompt. Do you mean you SSH'ed into the device?

                                            What imeant was that if i ssh to the box and run curl with the url, i still dont see the values being updated. The only case that it works is to run the url through a web browser.
