In Kibana I have a vertical bar chart with X-axis being timestamp and Y-axis being the median of a field. On top of that, the vertical columns uses a breakdown by top values feature to produce something like this:
How can I breakdown by field in OpenSearch?
For OpenSearch what you are looking for is to add a Split series sub-bucket to the Buckets section. You then set the sub-aggregation to Terms and select the field you would like to split by. You can then order this alphabetically or by a custom metric.
So the Buckets section of your visualisation should look something like this:
X-axis
Split Series
Sub aggregation: Terms
Field: <desired field>

Using kibana,
There's a way to filter the data for cases where a field exists, and there is a way to filter the data to get only requests where a field does NOT exist.
I'd like to plot a time histogram such that at each point I have a ratio of:
number of records where field X exists to the number of records where it doesn't exist.
How can I achieve this?
You can do it with a vertical bar chart. On the time axis you need to use a Date Histogram aggregation on a date field.
Then create a sub-aggregation (split series) and use a Filters sub-aggregation. You can then define two filters, one to filter documents for which the field exists, and another one for documents that do not contain the field. It should look like this:
I have a project in kibana integrated with elastic search.
In Kibana page I am displaying a chart with X(months) and Y(Euro) values.
I want to show a line in the chart that will show the average Euro value of all data.
For the moment I add a manual value to show the horizontal line in the chart. Chart example I want to show
I want to get average value automatically from my data in elastic search. Is there any option to do this task?
Thank you
Considering it is timeseries data, timelion can be used.
I have created dummy data as follows:
POST /balance_new/doc?pretty
{
"#timestamp": "2018-01-14T12:32:50.548Z",
"amount":136.5
}
There are more entries present like this.
Timelion query:
.es(index='balance_new', timefield='#timestamp', metric=avg:amount).range(135,140).title('Average EUR Monthly').yaxis(label='Average EUR'),
.es(index='balance_new', timefield='#timestamp', metric=avg:amount).aggregate(function=avg)
Graph look like:

I have a status field in my elastic search index which can take values Open,Closed,Clear,Intermediate,Ready for Approval. Right now, I have created a visualization and sorted this field descending based on the Term. What I want to achieve is - I want this to be sorted in this particular order Open,Clear,Intermediate,Ready for Approval,Closed.
How do I achieve this? One option I am thinking is creating a scripted field and prefixing with integer column, but I am not sure if I will be able to filter the visualization later?
If this list of possible values is a static list of known values, there is another way to define your visualization with a little more manual configuration. Just replace your terms aggregation with a filters aggregation and add custom filters for the possible values like so:
Kibana will respect the order of your filters in the visualization. From a performance perspective, this should also be better than using a scripted field...
With Kibana I have managed to visualize continious requests in a linear chart by:
using a line chart
Y-axis: Aggregation: Count
X-axis: Date Histogram with field #timestamp
Split Lines: Sub Aggregation: Terms Field IP address
Now I would like to get the average, minimum and maximum session duration out of this. Is this possible, I haven't quite figured out the right approach to take it from here.
You need to create dashboard to see all this data on one screen.
Save this visualization
Change Y-axis aggregation type to "Average"
Save this visualization with another name
Change Y-axis aggregation type to "Minimum"
Save this visualization with another name
Change Y-axis aggregation type to "Maximum"
Save this visualization with another name
Create Dashboard with all saved visualizations.
I am Using ELK to show graphs on kibana .
I have data set Below
ID|A|B
6|5|200
5|15|110
4|25|90
2|50|70
3|70|50
1|100|40
I want Line Graph without any use of Aggregation.
Any Suggestion.
The first step would be to get each value into its own field via logstash. Check out the csv{} filter, which should work with pipe-delimited values as well.
Then, in your kibana visualization, you can add multiple y-axis buckets to display each line. On the left side are two sections - one for the y-axis, and one for the x-axis. Add multiple y-axis values for each data series.
