I have a Kibana search that returns the load average in a field called metric_value_number. This indexed field has a format of Number, and a Numeral.js format pattern of "0,0.[00]". This is default values.
Here is a screenshot of my search with sample data
When I try to make a visualization with a sum-aggregation, it gets aggregated to zero. This applies to Visualization types of at least Line chart, Area chart and Metric.
How can I properly visualize the system average load with the data I have?
Found this thread, because I had some trouble myself getting our load visualized. However, it turns out I had to type cast to number first by using %{NUMBER:load_1:float} and actually needed an average aggregation.
Had to delete the Logstash index and "reload the field list" in Kibana to get it working.
Tried to reproduce your problem by using your settings. Unfortunately for you, I got it working. I am currently using Kibana Version 4.1.2-snapshot
Build 7500.

I want to calculate and display the average scroll depth in Data Studio from analytics.
I’m looking to get an average scroll depth in Studio. I’ve got the 10%,25%, etc scroll depth data coming in, but I now need to be able to calculate the average scroll % from this data.
To calculate the average scroll depth:
multiply the scrolled threshold by the number of events (10x500) + (20x400) + (30x475) +(40x300) + (50x200) + (60x100) +(70x75) +(80x60) + (90x20) + (100x10)
Then, take that total divided by the total number of events. 500 + 400 + 475... etc
Because I can’t reference cells in Studio I can’t get it to work. I’ve also tried Google Sheets, which does work to do the calculation, but then I can’t use Data Studios filter to provide a specific page path?
I'm thinking that perhaps the calculation will need to be done at data source, but I am not sure how to reference a 'cell'?
Data Studio doesn't work based on a concept of "cells", it works based on a concept of "fields"—which are basically properties of the data source. Similarly, you don't have "formulas" per se, but rather "calculated fields". These fields can be created either at the chart-level (single-use, but doesn't require permissions to modify the data source) or in the data source (reusable across many charts, requires permissions to modify the data source). Most fields also have an aggregation type, which tells the report how to aggregate it in charts by default (e.g. Sum or Average).
When you either edit your data source and hit "Add Field" or the option with the same name under the "Add metric" or "Add dimension" menus on a chart, you'll be presented with a box to input the formula. To access a field, just type its name (of if you're in the data source, select it from the list on the left). The editor will also typically give you an auto-complete list below your cursor based on what you're typing. Once your entry matches a field, it will get a highlight box around it (the color is based on the type; green = dimension/string,blue = metric/number). The functions available are sort of a mash-up of something between what you'd expect in Google Sheets and in a SQL query, but with more constraints on when you're allowed to use certain functions.
The documentation for calculated fields is pretty simple, so I'd recommend starting there before you try to do too much heavy-lifting in Data Studio. Because of constraints in Data Studio's data model, you'll often find that you need to create separate calculated fields for different parts of the formula, and then combine them in a new calculated field. I'll warn you that the error messages in the field editor aren't super helpful sometimes, so you may need to re-read the documentation for the functions and field types you're working with to ensure you get a valid result.
If you're running into problems, including the field names and values that you need in your calculation may help, including the source of the data (are these GA events?). The more details you give, including what you've already tried, the more helpful we can be. Also, make sure to read the docs first to make sure you have a good handle on the product you're using and the terminology the community is most likely to understand.
I have been playing with Grafana for a while, and got stuck with the following issue.
I need to produce a chart that displays the round trip time for some REST calls my application is doing.
I am using Dropwizard metrics and starting a PausableTimer when I fire the call, and stop it when the expected response comes back. From Grafana, then, I can see the data source I need but when I build the graph, I am forced to apply some statistical calculation on my data (stddev, mean, max, min, etc.) whereas all I need is to chart the numbers from the series.
Below is a screenshot of the config part I am referring to:
The dropdown contains a number of transformations to apply to the priginal data, and I cannot find a way to tell Grafana that I wans to display the data the way it is.
I am not really sure how to do this, had anyone had this issue before -- and solved it?
Thanks in advance.
I have discovered Kibana last week, I find this tool very useful but.. I can't help but wonder how can I bypass Kibana's limitation to one time range for whole dashboard (https://github.com/elastic/kibana/issues/3578)?
I need to present data for different time ranges on one page. It will include pie charts, data tables etc..
Unfortunately, you can't do that without changing Kibana's code to create a solution of your own.
Here is the github issue tracking the request:

I'm new to Kibana and want to create a visualization that shows percentage of unsuccessful events over time as a line chart.
I log an event for each of the cases: “Event success” and “Event error”.
Currently I have the two metrics in a single graph, but I don’t know how to calculate the percentage of unsuccessful events, i.e. count(“Event error”) / (count(“Event success”) + count(“Event error”)). Any ideas?
Kibana version: 4.1.1
We wrote a plugin for this.
https://github.com/outbrain/ob-kb-percent
All you need to do is to install this plugin.
Yes, you can go through the plugin, but sometimes there are issues in installing the plugin as it throws an error "No valid URL specified!".
Also for your this query you can try to access visual builder and calculate your unsuccessful events. Under data option in the visual builder, you can have math aggregation and try to perform your calculation.
Try this once, because this will give you graph visualization.
I've added the suggested metrics filter from http://logstash.net/docs/1.4.2/filters/metrics and can now see the metrics coming through in kibana, so for example I have the following fields:
http.200.count
http.201.count
http.304.count
http.404.count
along with associated rates (i.e. http.200.rate_1m).
I can create a graph if I add the various rates manually on the Y-axis, but that means I need to know the various responses upfront (not difficult in this example I guess), but is there anyway to tell Kibana to graph the various fields as separate lines?
I believe what you want is a "Split Lines" aggregation. If you have a field that you can use to distinguish the data, then you can use a "Terms" aggregation on that field and Kibana will graph a separate line for each unique value found in that field.
