I'm trying to create a Kibana visualization that shows the number of requests per service.
Service is identified through a Filter called Service_name
I believe I can use SUM, however, each visualization either shows the total of all the requests to all the services, or I can Filter by a service.
How do I create a Visualization so that the x axis shows the Service_name value, and I have a sum of each service_name on the y axis?
Any help on this would be appreciated!
I'd like if you could give a few more details about this. If it has Lens Visualization, you can first use Count in the Y-axis and then use the Top Values option under the Horizontal Axis Configuration to select the 'Services_name' field.
If you're using an older version, you can use 'Terms aggregation' option that comes under the X-axis.
Do let me know if this helps!

I want to set an alert on a graph in Grafana, but I am not able to set.
If the used value in graph exceeds above 27 TiB then it should create an alert.
Also, I want slack notification of grafana graph after every four or six hours. But I am not able to see any option for that. Can you please help me regarding this
Check the Axes tab --> X-Axis column: If you are calculating Total in the value part as you can see in the below
Then, change the avg() to sum() in the Condition:
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'm trying to graph out average response time from http logs. When I go to Visualize and try either a bar or line graph, any time that select a different Aggregation type besides Count(ie Average, Sum, Max, etc), I never get any values in the Field drop down. I believe that the X-Axis should/could just be a Date Histogram.
My query looks like this: "host:'hostname' AND file:'access.log'", which generates a ton of results as a Count, but again, can't seem to figure out how to graph out that other trend over time(outside of a count). I can confirm all my fields are being indexed.
Thanks.
The issue in this case came down to mappings, and how the fields were all being interpreted as strings, which makes it impossible to do any of the other number related Aggregations. The only way I found this out is via a tweet from Rashid(the lead dev of Kibana) tweet from Rashid to me.
Essentially, as documented in the grok docs, I needed to define the mapping type:
%{NUMBER:request_time}
Became:
%{NUMBER:request_time:float}
After re-indexing and re-mapping, now my fields are mapping to the right type, and now I can do number based aggregations.
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.
I would like to know that is there any way (or workaround) to draw moving average on Kibana dashboard?
I have read all the documents on the official site and nothing about moving average (or advanced charts) are mentioned.
Any information or keywords will be helpful, thanks in advance:)
You can create a Histogram Panel with Chart Value as mean, select your preferred Value Field (i.e. the field on which you want to get the average), set Chart to Lines and then set Auto-Refresh to your preferred interval:
Then you will get something like that:
