Cumulus MX and Cumulus 1 data

From build 3044 the development baton passed to Mark Crossley. Mark has been responsible for all the Builds since. He has made the code available on GitHub. It is Mark's hope that others will join in this development, but at the very least he welcomes your ideas for future developments (see Cumulus MX Development suggestions).

Cumulus MX and Cumulus 1 data

Post by Jim_AFCB »

Hello all,

Currently running Cumulus 1 on my main Weather PC to run my website... alongside Weatherlink and VirtualVP.
Downloaded Cumulus MX, and testing it on another machine, connected successfully via network to Virtual VP.

I copied all the data from Cumulus 1 across, and it's there when I browse the data.

1. How do I get the graphs on MX to reflect all the data I have going back to 2009? Currently have only a day's worth that was downloaded when I fired MX up.
2. is there an easy way to automatically populate the monthly station records from the data? disregard, I found how to do it.

Thanks.

Please clarify what you mean by 'and it's there when I browse the data'.
Browse it by what means? Can you see it in the tables viewed in the CumukusMX web interface? Or only if you look in the directory where you copied it?

Did you copy "Cumulus.ini" across too? Does that file start with a capital letter just as I have written it?
In Cumulus 1, the file could be called "cumulus1.ini" and still be found, but MX is very fussy!

One difference between C1 and MX is that MX actually takes notice of the contents of "StartDate=" date in Cumulus.ini file [Station] section. (Cumulus 1 reads all files that it can find, and all it does with that date is output it twice on one web page). That date is not in any MX settings screen, but it is stored within Cumulus.ini, so if you did not copy the C1 file across, the default (for graphs and everything else) start date would be when you started MX.

Read the instructions at https://cumuluswiki.org/a/Migrating_fro ... us_1_to_MX if you need to know more.EDIT: that URL has been updated.

By "Browse the data", I mean in the CumulusMX web interface. Yes I had copied cumulus.ini across as well.

sfws: I had the start date down as 27-03-1996, as that is the date that shows up on the Records page, as the start of my records, but thats when I started my station using Weatherlink. I have now changed it to 01-01-2010, restarted MX and reloaded the web page.. but still only got the very most recent data. So I don't think thats the fix.

So thought 1, was rubbish.

Thought 2: When I started testing MX, (and still had C1 as my primary), I had problems with an existing web page that I had designed to show me spot values for the same time on each day in past week. It uses "recent history" web tags (as Cumulus only provides today and yesterday tags, I needed values for earlier days), MX was only able to show values since its start, it was not populating the web tags for earlier days.
I raised my issue here but the answers did not resolve why MX could only assign values to most recent tags.
Since each subsequent day more got populated, I concluded the answer was MX was not able to output data from before when it was first run.

So I now believe the answer for you is the same, MX is obviously creating another "database" (or internal storage) of some sort, we have not been told about, that it uses for your graphs and my recent history tags, and that "database" is not being populated when MX is first started with past data.

We will wait and see if anybody else can explain more, or come up with an alternative explanation.

I think you need to define "only recent data" in the context of being displayed on the graphs. And which graphs, admin interface or web site.

Just checking that you did realise that: "If your "Cumulus.ini" was actually called "cumulus.ini" you should rename it to start with a capital letter." Cumulus MX doesn't recognise it uncapitalized, so it will behave as if it did not exist and create a new file.
