I send to logstash the amount of cores used on my cluster. I want to create a pie chart on Kibana that displays the number of cores used in the last 24 hours, but aggregate the values - i.e. display the values as 0-10 cores, 10-20 etc. How do I do that?
In kibana choose visualisation then choose pie chart then choose range in the aggregation dropdown

I want to plot time on x axis and a numeric field 'f' occurring at that time on y axis in kibana 4.
I have changed the data type of 'f' to integer and I can confirm that it has changed from kibana index settings.
However, the only aggregation options available for Y axis are count/min/max/sum etc. This post has an answer for plotting sum but I'm interested in plotting actual values.
Is there a way to do this?
You probably want to check this.
tl;dr
The data you want to plot, are not numbers.
Update your grok filter to something like this %{NUMBER:time:float} instead of whatever you have.
Re-index/re-hash your elasticsearch (i just deleted my data and restarted the whole thing)
Goto Kibana4 -> Visualize -> New line graph
In Y axis select max and in the field, select your number field.
Kibana is plotting a bucket, e.g. every minute.
As such, aggregations are in order. I frequently plot average and max on the same chart to give me a good overview.
If you reduce the time period, the buckets get smaller, but I don't think you can ever make them "just 1 document".
The histogram i created with my data is shown as a thick block. There are valid hits numbers and dates on the y and x axis respectively, which indicates the data is proper. What can be done to scale it down to an understandable one?
The problem with your histogram is that the data you have indexed would be having a good frequency against the date and/or the data might be months old. So the default interval option for Kibana is set to one year.
You can change it by changing the default time period from "year" to any other smaller values under the section "view" (marked as 1 in the below figure) in the "Interval" dropdown (marked as 2).

I have collected CPU usage for a process for every 0.5 second. Now I want to plot a graph, but I am not able to figure out which tool to use. Using Excel or Libre, I can easily plot the graph however it will be too big (since there are approx 4000 CPU usage records). So is there any online tool available, which would display the graph as I wish ? like I could set to see the graph for every 5 mins or 10 mins of CPU usage etc? Where can I flexibly change the range of X-axis ?
EDIT : Google Graph seems to have something, currently I am trying to figure out.
These might help you..

I have a long list of Linux timestamps, representing the second that events occurred over a one-hour period (3600 seconds). Most events are separated by 3-4 seconds but some are separated by one second and some happen at the same second:
1371995100
1371995103
1371995106
1371995106
1371995107
1371995109
1371995111
1371995113
1371995114
1371995118
1371995121
I would like to plot this data as a series of lines representing "event happened", as such (notice that 1371995106 occurs twice):
Actually, since one-second resolution is finer than necessary, but density is important, events that happen at the same time can 'carry over' to the next free second (so it would appear as if the second event that happened at 1371995106 were plotted against the next free second, which is 1371995108):
Can this be plotted using CLI tools in common Linux distros? I have tried plot (gnuplot) but been unable to find examples of creating graphs from one-dimensional data.
You are trying to do a frequency plot. Assuming your data is in a file called data then
set format x "%.0f"
set boxwidth .9
set style fill solid
plot 'data' using ($1):(1) smooth frequency title 'Frequency' with boxes
format stops the label being output with exponents
boxwidth sets the width of the box so there's a gap.
The style is set to filled boxes
smooth frequency sums the y values which are set to 1 by the :(1) the x being the first field in the file ($1).
I'm building a simple webapp that will display different charts about relationships between income and health. I'm trying to use Google Fusion Tables to generate the charts, but I've hit a snag. I have 807 rows in a chart and am trying to make a scatter plot between two columns.
It says all rows are being displayed, but the chart clearly doesn't have all of the data points. How can I get all of the points to display?
Charts in Fusion Tables are limited to 500 data points. When the count goes above that the scatter chart uses a sampling algorithm to trim the data to that limit. This should be indicated on the chart; I've filed a bug for that.
