Fixed Timeshift and Moving Average on 0.0.5

[drsoares]

Issue fix, #122. Inside TimeShift functions and MovingAverage there were some results not wrapped into promises leading into the following issues:

Datasource: OpenTSDB

[Gauravshah]

@ShilpaSivanesan had we not fixed this as part of previous PR ?

@ShilpaSivanesan had we not fixed this as part of previous PR ?

Yes I added this at this.query
here is the PR #118

@drsoares added this specifically for timeshift.
But our fix should handle this

[drsoares]

Those two parts were missing and not working for OpenTSDB at least. Inside timeshift and movingaverage methods, please double check. I'm assuming that 118 is already released on 0.0.5 version.

[drsoares]

Some other datasources are experiencing the same problem.

#124 (comment)

[xpatos]

I can confirm that this fix works in my case for elastic search. I just applied the fix in Chrome Dev tools. Please merge this PR.

[Gauravshah]

@drsoares can you help me understand why does this fix things ?
we are converting all before sending it to grafana

grafana-meta-queries/src/datasource.js

Line 89 in c9042c9

if(ds_res.then){

Not working on grafana 7.4.5 with influxdb

[xpatos]

@drsoares Can you please help @Gauravshah understand what is the problem so our graphs can start working again.

[earth08]

I started using autohome-comparequeries after waiting so long

[drsoares]

Apologies for the long absence. @earth08 do you mean this change or the plugin before the change?

@Gauravshah I think the best explanation is trying to reproduce the error with the mentioned datasources. (influx, opentsdb and elasticsearch) I wonder if there's any in which this plugin is working, not sure if there are any behavioural diferences bettween the query datasources from different plugins, the contract is the same and never returns a promise, it results an observable. I've just let that if statement to make it consistent with the remaining plugin.
Cheers

@drsoares
I have never got it working,
In my case arithmetic is working, but timeshif doesnt

[drsoares]

@earth08 but have you tried with this patch? Without these changes only arithmetic was working for me as well.
Cheers

[earth08]

@drsoares which patch,
As I only see 0.0.5 version
And time shift is not working

[giom-l]

I confirm this fix perfectly works with grafana 7.5.2 and metaqueries 0.0.5 (tested with timeshift)

[xpatos]

Since @Gauravshah seems reluctant to merge this fix, can we create a fork or use a branch or something. Many graphs in our company is broken due to this bug. It has soon been two months since this bug was reported.

[garyhodgson]

Can also confirm that manually applying the change in this PR and restarting grafana got timeshift to work again (grafana 7.5.5)

[earth08]

How to apply and what change are u talking about?

How to apply and what change are u talking about?

I just applied the changes detailed here: https://github.com/GoshPosh/grafana-meta-queries/pull/128/files

• On the grafana server go to the plugins folder.
• In the grafana-meta-queries folder is a file called datasource.js. Open this file in an editor.
• Go to line 202 where it says "return ds.query(options)" and replace it with text:

var ds_res = ds.query(options);
if(ds_res.then){
    return ds_res;
}
else{
    return ds_res.toPromise();
}

• do the same for line 271.
• restart grafana.

[elluishinojos]

Any updates on this? This plugin is really useful, but there is no way to manually update a plugin at Grafana Cloud and this is supposed to be the only plugin available that is supposed to allow to do time shifts

[Gauravshah]

@drsoares can you remove some of recent commits so that this PR can be merged. we have another competing PR here #132 was trying to avoid merge that

[ShilpaSivanesan]

@drsoares could you please pull the latest master and update this PR
Also please push dist/datasource.js

[ShilpaSivanesan]

Fixed here #141

[giom-l]

I still don't understand why this issue is closed.
I installed tag 0.0.8 some minutes ago, and I still hit the same issue with timeshift function.

runRequest.catchError TypeError: data is undefined
    promise https://grafana/public/plugins/goshposh-metaqueries-datasource/datasource.js:322

When I apply the patch stated above in datasource.js
replace

 return ds.query(options);

with

var ds_res = ds.query(options);
if (ds_res.then){
    return ds_res;
}
else {
    return ds_res.toPromise();
}

on lines 301 & 232
everything is working really fine.

Unless I'm missing something, #141 does not fix that point.

[giom-l]

I added a new PR to integrate changes proposed by @drsoares based on uptodate master branch.
I also added some stuffs in docker-compose for testing
#145
