I have setup a dashboard that displays incoming message rates in a graph, filtered terms in a pie graph and all with nothing really to do. I want to be able to display a table/graph or some other type of panel to display elapsed time between two datetime fields that appear in my message:
{"pubDate":"2014-02-27T07:11:44",
"fetchDate":"2014-02-27T07:11:55",
"client":"ME",
"query":"(work OR my job boring OR mundane OR stodgy OR interesting
OR sucks OR exciting OR fun)",
"lang":"en"}
What I am able to get now is a language filter graph, and a query filtered pie chart with the normal incoming rate graph as well. I want to create a graph/table that gives the difference between the pubdate and fetchdate. Is this possible?
Also related to same project is that the query field does not work correctly in that elasticsearch seems to break long queries into individual terms and I wonder if it interperates the OR itself or just based on length.
Any advice appreciated.

I'm using several time series panels on my dashboards, which are showing the values based on the selected time range.
Now, I want to add a gauge panel, which should show the number of payment transactions since midnight (although I know all the problems about server restarts, the feature of the rate function, etc. the gauge panel will an interesting part of my dashboard). So my query has to be independant from the selected time range of the dashboard.
I've found the variables ${__from} und ${__to} in the Grafana docs, but I'm not sure, how I can use them in a query or how to use them flexibel, e.g. getting the current daten/time as "to" and calculating "from" als midnight value.
Has anybody an idea, if this is generally possible?
Thanks in advance

I am trying to use the drill through filter to take my user to other data related to that date. Essentially I have an overview page and I want the user to click on a date and drill through to the next page, where it will show them test scores nearest to that date.
I think I need to do two things 1) store the filter date as a variable so I can use it to find the nearest test date to the filtered date 2) create measures which ignore the filtered drill through date and can for example calculate the minimum or maximum test scores on all the tests overall.
I'm not sure if either of these options are possible but any help is greatly appreciated. TIA
I have two filters transfer* and transfer_failures. Each filter is the output of a database query using ES DB queries. I need to visualize a graph that aggregate monthly the number of transfer_failures/total transfers in the month.
Both have timestamp created field with the same format, but I wanna know how to plot table that uses two filters!
So suppose I have 40 total transfers on May 'should be calculated using the transfer* filter' and 10 transfer_failures 'should be calculated by the transfer_failure* filter' so the graph should blot 10/40=.25 on May supposing building a Vertical Bar.
I've some screenshots to show, but I am not allowed to post these here.
You can use the filter ratio aggregation on Visualize -> TSVB/Time Series Visual Builder if you want to calculate percentages using two filters.
My app has a class that saves picture that users upload. Each object in the class has a city property that holds the name of the city that the picture was taken at, and a like property that tracks the number of likes.
I want to be able to send a query that returns one picture per city and each picture should have the highest ranking of likes in the city it belongs to. How can I do that?
One way which I first thought about is doing multiple queries by fetching the most liked picture of a city and save it in an array, and then do the same to other cities.
However, each country has more than one city, thus it's not that efficient.
Parse doesn't support the ordinary operations used in databases. Besides, I tried to use a compound query. Unfortunately, I can't set limit or ordering on the subqueries. Any good solution for this?
It would be easy using group by. Unfortunately, Parse does not support "select distinct" or "group by" features.
As you've suggested you need to fetch for each country all the cities, and for each one get the top most rated photo.
BUT, since Parse has strict restrictions on the duration time execution of a request ( 3 sec for an event listener, 7 sec for a custom function ), I suggest you to do this in a background job, saving in a new table the top rated photo for each city. In this way you can easily query the db from client. The Background jobs can be executed up to 15 minuted before parse drop them, so you could make that kind of queries without timeouts.
Hope it helps
After performing a product evaluation by one of the managers other can change the scoring for certain categories. This changes in scoring are stored in the database for reference.
The structure of the evaluation is like this:
Evaluatoin
- Category
- Scoring point
an evaluation can have many categories which all can have many scoring points.
My problem is the following:
If I change a scoring point a few times all is entered in the database but in the reports i am only seeing the first scoring point. The rest of them with the same name are left blank but are using space just as it would if all were visible. The stored procedure that is delivering the data is working fine. It bring all data to the report which then displayes it wrong.
=Fields.CategoryName is working fine... every category name is displayed correctly
=Fields.ScoringPointName is not working... it displayes only the first and leavese all the rest blank... if for example a scoring point name is Product robustnes it would display only the first change of scoring but wouldnt display the rest
Any ideas???
Found out what the problem was. Maybe it will be helpful for other people
I was showing the data in a group header section with grouping =Fields.DefinitionText. Thus it will only repeat if the Fields.DefinitionText is distinct. About the empty space it's caused by the detail section that repeats for every data record. Thus if I want to display all of the data records I have to move the group header section textboxes to the report's detail section.
Here and Here are some usefull things about reporting.
Cheers
