MetaQuery breaks in latest version of Grafana

[yuvarajhere]

From version 6.4.2, the metaquery plugin breaks and doesn't return any value. The reason might be the Grafana recent version is using a different data format and it breaks the plugin.

I have tested with "Arithemetic" type and not sure about the other types.

Error Message:

Can confirm that something with metaqueries and grafana is not working as it used to. I use metaqueries to retrieve data from the source, but plotting in grafana returns undefined error.

Same problem here. I don't even get an error message. My browser hangs up if i try to use metaqueries. (Grafana 6.4.3 on Ubuntu Server)

We also have error after upgrade to 6.4. Plugin works great with data from Elasticsearch, but error appears when datasource is Prometheus

Grafana 6.5.0-beta1 is showing similar behavior. I receive an error message when using it with multiple Azure Application Insight data sources which were previously working in 6.4.x

Each query and panel displays:

Metric request error

@tonymadbrain It should generally work with any datasource , can you help with 1 metric and 1 meta query on top of just trying to print the same value ?

[Gauravshah]

@bhozar can you add stack trace and dashboard config ?

[bhozar]

^ You mean this bit of the config? Where can I find the stack trace?

[bhozar]

Found it:

error="{\"error\":{\"message\":\"The request had some invalid properties\",\"code\":\"BadArgumentError\",\"details\":[{\"code\":\"BadArgumentError\",\"target\":\"granularity\",\"message\":\"Failed parsing 'PTPTMM' as ISO8601 duration\"}],\"innererror\":{\"code\":\"QueryValidationError\",\"message\":\"Failed parsing the query\"}}}"

Looks like it works if I set the time grain to something else:

[Gauravshah]

@bhozar thats the error, can you send trace. It should be part of browser console

[bhozar]

Unfortunately I cannot replicate it now. Changing the Time Grain and changing it back seems to have fixed it. If it happens again I'll grab the browser console trace.

For me there isn't even an error. It does not even display any data when selecting metaQueries data source ("No data"). Selecting prometheus data source in the panel works fine for the shown query. Browser console looks clean.

Query inspector returns valid data:

  xhrStatus:"complete"
  request:Object
    method:"GET"
    url:"api/datasources/proxy/1/api/v1/query_range?query=up&start=1574116920&end=1574289720&step=120"
  response:Object
    status:"success"
    data:Object
      resultType:"matrix"
      result:Array[8]

Any idea how to debug this?

Grafana v6.4.4 (commit: 092e514) Promethes version: 2.14.0

@tonymadbrain It should generally work with any datasource , can you help with 1 metric and 1 meta query on top of just trying to print the same value ?

my metric:

when added metaquery with timeshift by default:

when changed timeshift to arithmetic, just no data:

[Gauravshah]

@tonymadbrain Query -- MIXED -- is incorrect. It should be Query -- Meta Queries --

[tonymadbrain]

@tonymadbrain Query -- MIXED -- is incorrect. It should be Query -- Meta Queries --

If I choose Meta Queries there is no data at all:

Also no errors in console

[Gauravshah]

@tonymadbrain I am unsure why prometheus would not work

[siegmund42]

@Gauravshah Can we somehow support debugging this? Although #84 is now fixed, this still makes MetaQuery unusable for prometheus users. (Problem persists with Grafana 6.5.2)

[Gauravshah]

@tonymadbrain @siegmund42 I can take a look at prometheus after 2 weeks. I do not know Prometheus so if you can add a link that can give prometheus test machine with sample data that would be helpful.

[siegmund42]

@Gauravshah You might want to use this Prometheus demo server as data source (I've already added a very basic query to the URL): http://demo.robustperception.io:9090/graph?g0.range_input=1h&g0.expr=up&g0.tab=1

[siegmund42]

Any news on this? I just took a quick look in the javascript console and it gives: TypeError: this.props.panelData is undefined PromLink.tsx:23:19

Anyway, request and response data look good so it's just a matter of presentation I guess.
