(Othel Yarwick) #1

Hi guys. I am having some weird issue with my emoncms feeds page. Before I proceed a bit of an intro to my configuration.

I have the raspberry pi 3 connected to 3 victron devices via serial to usb cable. I setup emonhub with the appropriate interfacer config and all that works fine. The RPi is based on the latest stable emonsd image.

I also created an emoncms instance on my VPS and pointed emonhub to put data to this emoncms instance installed to the cloud. All was well with the world and I had no issue.

2 days ago while trying to install a graph module on my emoncms installed in the cloud. I did a git pull in the emoncms web root directory which I believe pulled in the latest emoncms files from git. The graph module installed fine without any issues.

However yesterday I started noticing my dashboard was devoid of any data whatsoever. The feed/list page is also stuck in loading. Weirdly though. The dashboard works fine from my android device with chome browser (I run Kubuntu on my laptop with chromium) but the feeds page also does not load on the phone…

Below are some log/ debug outputs and also some information about my version of emoncms

emoncms feed json file seems to load fine http://energy.bobby.com.ng/feed/list.json

when I load the feed page with developer tools on chromium I get the following

what I have done and checked

Time stamp on the emoncms and emonpi are the same. The node page loads fine and the nodes are updated every 22 seconds and the values are as it should be. Again athough the feed page does not load on my mobile phone, the dashboard and all the values works fine on the phone browser.

What could be wrong with the emoncms. Could the latest update from git have broken something?


(Othel Yarwick) #2

It seems for some reasons, emoncms is requesting for a feedid that does not or never existed. could this be as a result of update I ran? I don’t know much about emoncms internal working or programming for that matter, but it seems emoncms tries to load feeds are don’t exist and is thus through that error. I can recreate the error if I try to view the value of feed through json. valid feed values are displayed but when I trying to view feeds with id1 or 0. it throws up the request feed does not exit error.


(Brian Orpin) #3

Did you run a database update?


(Othel Yarwick) #4

The more I look at this the more it is obvious that something is seriously broken since I ran the git pull on the emoncms web directory. I just noticed that I can not even create dashboard entries for existing or even new dashbaords… and it is looking more and more that I have to recreate emoncms from scratch!

I think documentation for installing new modules should remove the requirement for updating emoncms via gitpull or better still add a caveat so the user knows the implication. gitpull updates emoncms files to the latest from git… however there is a recommended for upgrading emoncms which requires backing up database and some directories/files all of which I did not do because I followed the documentation for module installation to the letter.


(Othel Yarwick) #5

I did.


(Brian Orpin) #6

Don’t get too hasty, it is likely something that can be fixed (though outside my knowledge area) especially as the mobile works. The database is likely to be fine (they are actually just files).

Yes updating can be a little fraught. As with any system a backup is always a good idea :slightly_smiling_face:.

Have you tried building a new dashboard and visualization?
Is your logging set to ‘INFO’? If not that may give you some more information.

Can you run this command from the command line git -C /var/www/emoncms/ status (with the right path) which will confirm the branch you are on.

One of the beauties of Git is that you can roll back if necessary though I would not know what the best way of doing this is.

status
On branch stable
Your branch is up-to-date with ‘origin/stable’.

Thanks for that suggestion. I now have the following in the emoncms log file

Yes. I tried building a new dashboard but I am unable to create entries or objects because those are missing for the toolbox. I am able to create visualisation though

besides the occasional feed does not exist which comes up once every 2 3 hours. Everything from the logs seems fine. Yet my dashboard is empty of any data or values and the feeds page is completely broken and stuck in loading.

I feel the upgrade broke something. I just can’t figure out what. I really should never have followed the documentation for module installation blindly.

On my phone. I have a strong feeling the mobile works because it has some data cached from before the update to emomcms was done. A friend confirmed the dashboard does not work on his phone. I also doubt a roll back would work but it is something I won’t mind giving a try.

Hi

You may need to do a git pull in some of the sub directories of emoncms. I had a display problem recently and went through all the directories under Modules and did a git pull on each. Some were up to date but some updated. This solved my problem. A git pull in /var/www/emoncms does not update everything.

Regards

Ian

This makes a lot of sense. I will try it and update this page once I am on a pc

There is an update script in the useful scripts repository. It will update all the different Modules that are not included as part of the core - just check the hardcoded path.


(Othel Yarwick) #13

That was it!.. I went to the different modules and did a git pull… The issue was from an outdated dashboard module which was updated with a git pull. All is well with the world again :smiley: Thanks.


(Othel Yarwick) #14

Thanks for the tip. It is a keeper.


(Othel Yarwick) #15

How do I mark this thread as solved?


(Othel Yarwick) #16

Dashboard is at http://energy.bobby.com.ng/dashboard/view?id=1 in case anyone wants to confirm. I can confirm it works on my computer and the feed list is now also working fine

Click on the ellipsis ( … ) below the reply that solved the problem, then click on the Tick.

Looks like it’s working OK. I clicked the D/W/M buttons on your graphs and they updated straightaway. Everything else was updating at regular intervals.

Nice looking dash, BTW.


(Othel Yarwick) #19

Thanks :slight_smile:

Did an upgrade on my good old pi2 with a new emonsd … it went rather well and I even could get the backup in but I think I have the same issue

the solution seems to be a git pull … ooookkk heu can a nice person write down the correct command before I blow up the full stuff please ?? :grin:

I tried the useful scripts but that didn’t give any change … except that it is loading data and pushing it to a remote emoncms … just that error when I go to inputs or feeds page.

thanks a lot
