Changing Data Source but Retaining Data Point History?

mihairosu

Looks to me like this is something we would be interested in pursuing in case we want to change the data source:

It would be possible to achieve what you want by terminating mango and performing some operations on the database to change the dataSourceId column of the data point to the new source's id. This is not recommended but is possible if you know what you are doing.

With regards to this:

There are some migration tools with the NoSQL module assuming you use that for you point value store. Those tools coupled with the JSON Import/Export feature would likely work. The other option is to publish the data to the enterprise server assuming you are ok with the point becoming a Persistent TCP type data point and it won't have to be attached to a BACnet data source.

I may not have explained myself well or misunderstood your instructions. I want to make sure we're on the sama page. We already publish this data point to the Enterprise server, so there's no need to move the actual data from the ES. I'll attach an image, it might work best:

Just my few cents here @mihairosu, if you're going to go direct and your server is in the cloud, sorry to jump in Terry

How feasible is it for you to set up a VPN?
That will give you the ability to send data across the VPN into the server direct without firewalls posing an issue. This is also assuming you set up a bacnet server on a linux/windows box. //actually I think this isn't a concern here...
1.a) ALSO, have you tested this with a standalone unit to see if it will talk to your server direct without the mango in between? no point otherwise
Export all of your pointValue data and your point configuration data so your xids and names all line up from the mango unit
export any additional data from the enterprise server as you may have used a publisher prefix on your XID, be sure to amend the point value data export XIDs to match your system (remove the prefix in other words)
create a new bacnet data source, amend your exported point configs datasourceXID to match the new one then import. (or simply import the old datasource)
import your point values.
assuming bacnet works over the web you should be able to update the connection and go for it.
Terry if there's anything I've missed lemme know!

Hey Matt,

Actually this is all on the same internal network, I only need to migrate the data source between the two devices. Network communication is not a problem.

Thanks for the very helpful instructions; as soon as I get a chance, I'll see if I can work it out.

MattFox

I hope they're helpful! Looking back it looks a little bit like gibberish! Gimme a bell if you need anything

So right now I'm trying to backup and data itself.

We got 23 data points collecting data over many years.

I can't fit enough data into one watch list graph even from one point to be able to download it all.

I can't download 5000 points at a time for 23 data points.

Is there another reliable way to download all of this data?

MattFox

Yep,I remember here being a post by Jared:

<ma-watch-list-get ng-model="designer.watchList" parameters="designer.parameters" on-points-change="designer.points = $points" id="29305bf3-cc2a-4bac-9650-3cbf64d738a9" watch-list-xid="WL_Flow"></ma-watch-list-get>
<div class="ma-designer-root" id="1a2a6980-f5bb-4acc-a41a-f8f69d5c12d2" style="width: 1366px; height: 768px; position: relative;">

    <ma-calc input="designer.points | filter:{name:'Flow'}:true | maFirst" output="point"></ma-calc>
    
    <md-button id="2585b1fa-a630-4255-8670-41884b8754e2" style="position: absolute; left: 260px; top: 70px;" class="md-raised" ng-href="/rest/v2/point-values/time-period/{{point.xid}}?fields=TIMESTAMP&fields=VALUE&fields=ANNOTATION&from={{dateBar.from.toISOString()}}&to={{dateBar.to.toISOString()}}&format=csv2" download="{{point.name}}.csv">Download values</md-button>
</div>

Set your time period and off you go!

mihairosu

Okay cool I'll give that a try and report back. Thanks Matt.

MattFox

np, look at the button, that's where you'll want to set your variables. If you get stuck lemme know.

mihairosu

I am getting these errors when trying to import data point configuration for every point:

Data point with XID 'boosterPumpsOutputPress' does not already exist and references a data source that does not exist. Ignored.

I'm probably not following your instructions 100% somehow, I'll try to understand better.

MattFox

Probably show me your entire markup.
If this is a data-point configuration your dataSourceXid property must match a datasource that already exists in your system.
The markup I gave you above exports point-values.

mihairosu

@mattfox

What parts of this script should I be changing to get the points I am looking for?

<ma-watch-list-get ng-model="designer.watchList" parameters="designer.parameters" on-points-change="designer.points = $points" id="29305bf3-cc2a-4bac-9650-3cbf64d738a9" watch-list-xid="WL_Flow"></ma-watch-list-get>
<div class="ma-designer-root" id="1a2a6980-f5bb-4acc-a41a-f8f69d5c12d2" style="width: 1366px; height: 768px; position: relative;">

    <ma-calc input="designer.points | filter:{name:'Flow'}:true | maFirst" output="point"></ma-calc>
    
    <md-button id="2585b1fa-a630-4255-8670-41884b8754e2" style="position: absolute; left: 260px; top: 70px;" class="md-raised" ng-href="/rest/v2/point-values/time-period/{{point.xid}}?fields=TIMESTAMP&fields=VALUE&fields=ANNOTATION&from={{dateBar.from.toISOString()}}&to={{dateBar.to.toISOString()}}&format=csv2" download="{{point.name}}.csv">Download values</md-button>
</div>

I'll re-create the data source because it's easy in bacnet, but I am still trying to figure out how to download the data easily.

I don't fully understand what XID I need to match to something in my own syste,

There's no point XID in there, as far as I can tell.

MattFox

I'll break it down for you. The code above is filtering out a single point from a watchlist using ma-calc, the first point with Flow as the point name.
I think for you, my focus was around the button itself. I'll throw together some markup for you here. Since it's 23 points we should be able to knock them out with an ng-repeat....

<!-- 1. Generate a watchlist with your desired points that you want data for -->
<ma-watch-list-get ng-model="designer.watchList" parameters="designer.parameters" on-points-change="designer.points = $points" watch-list-xid="[YOUR_WATCHLIST_XID_HERE]"></ma-watch-list-get>

<!-- 2. ng repeat the buttons for each point in the list -->
<md-button  ng-repeat="point in designer.points" id="{{point.xid}}_button" style="" class="md-raised" ng-href="/rest/v2/point-values/time-period/{{point.xid}}?fields=XID&fields=TIMESTAMP&fields=VALUE&fields=ANNOTATION&from={{dateBar.from.toISOString()}}&to={{dateBar.to.toISOString()}}&format=csv2" download="{{point.name}}.csv">Download {{point.name}} values</md-button>
</div>
<!-- 3. use the date bar at the top of the page to set your time span -->
<!-- 4. hit the download button! -->

Ok I found the watch list for a test watchlist ID: WL_883061

{
         "xid":"WL_883061",
         "data":null,
         "query":null,
         "readPermission":null,
         "name":"Troubleshooting",
         "dataPoints":[
            "boosterPumpsFlowRate",
            "DHWBsmntReturnRate"
         ],
         "folderIds":null,
         "params":null,
         "type":"static",
         "user":"admin",
         "editPermission":null
      },

The page appears to work fine:

0_1583345621374_watch list download page.png

Data begins approximately Feb 7, 2017, so I set a test download from

Feb 7, 2017 to March 4, 2020 with 1 day rollup interval:

0_1583345750582_b2a128af-be91-4116-98e7-bbcda9e61382-image.png

I was getting lost connectivity and restored notifications.

Anyway, after the server is finished doing whatever it is doing, with a high processor load, I get an error for the CSV download:

0_1583348255792_de8facaa-05ec-4d97-b91a-3a88f54b3d25-image.png

Any idea what the issue may be?

I tried a smaller time period for the download and that had no problems.

I assume it's some limit in some sub-system that I may have to adjust values for?

edit: I think I see what the issue is. ma/log shows this error:

ERROR 2020-03-04T12:36:28,716 (com.serotonin.m2m2.rt.maint.BackgroundProcessingImpl$RejectableWorkItemRunnable.run:632) - Error in work item
java.lang.OutOfMemoryError: GC overhead limit exceeded

MattFox

Looks like you may need to break it up. Secondly, check your point limit count under the ui settings.

mihairosu

Okay thanks for everything, I can certainly handle it from here! If anything, I'll have to split it up, like you said, though I would have hoped to be able to get more out of this method. I hope it's more than I can get out of the watchlist page, haha.

MattFox

Another idea: add &limit=10000 to the url. That will override system limits rather than setting a higher settings limit.

Fox

mihairosu

Okay awesome, I'll play around with stuff, see what works well.

mihairosu

@mattfox said in Changing Data Source but Retaining Data Point History?:

&limit=10000

Since the last time we worked on this, this '&limit=10000" does not allow the page to load.

Anyway, the mango install just can't handle downloading an entire data set for even a single XID. The whole mango service comes to a slow crawl, as it pegs all cores to 100%. All screens can't reach the mango service, and in general is not ideal. And in the end, it still can't download it.

Plus how am I supposed to re-upload it. This download format is different than what you get using the watch list page downloads. Tn addition, the timestamp column appears messed up =( There are also not enough rows in excel for some of this data, I suspect, lol.

I will have to continue this conversation with IA.

As far as I can tell, there's no decent way, for the lay-man such as myself, to manipulate large amounts of data and other critical information. I suspect a lot of back-end work would have to be done to allow for such functionality.

My uneducated guess is that the whole structure is a bit rigid.

I'll keep putting this work off until a good solution appears, or I can get help directly from IA.

MattFox

I'm really sorry man. I'd hoped you'd been able to crack it.
Perhaps I should write a user module for you...
