kibana how to visualize cache hits and misses? - kibana

Hi, I'm new to kibana visualize.
Background
I want to visualize cache hit ratio of api response.
when it's a hit I log ...: “<url…> <some info…> USING CACHE”
what it's a miss I log...: “<url …> <some info…> NO HIT”
Query
I made two Y-Axis (picture below) but two graphs are same...
Question
How do I show cache hits and misses in one graph?
Do I have to add a new filter? or X-Axies?

I remember wrongly the options about the Y-axis in the aggregation based visualizations. You can build those kind of visualizations both with TSVB and Aggregation Based viz.
With TSVB you just select the index pattern in the panel options (you can also restrict the documents searched with a Kibana query in the "panel filter")
In the data section you can build two filter metrics: in the example "error" and "warn", but in your case you can produce a "hit" metric with query string content: "USING CACHE" and similarly with a "miss" metric with content: "NO HIT"
If you instead want to use an aggregation based visualization like in your screenshot, you can split the series like in the following example

How to create a chart in stack driver which will show the counts of API label from logs

I am very new to stack driver and trying to implement some charts which i have implemented in splunk for a different product.
We have the api name in the logs under textPaylod field and i want to extract the api name from the field and create a chart based on the counts of API names.
ex below is the sample log.
type: "k8s_container"
}
severity: "INFO"
textPayload: "19-04-29T04:30:51.058+0000 INFO PostFilter: POST response to http://<endpoint>/abc/def/users/getNames
"
timestamp: "2019-04-29T04:30:51.059143860Z"
}
type: "k8s_container"
}
severity: "INFO"
textPayload: "19-04-29T04:30:51.058+0000 INFO PostFilter: POST response to http://<endpoint>/abc/def/users/getPhoneNumbers
"
timestamp: "2019-04-29T04:30:51.059143860Z"
}
I've create a custom metric and extracted the text after "/abc/def" into API_NAME label expecting to use it as group function in the metric.
Crating Custom Metric
When i tried to explore the metric and see the counts in a stacked bar i am not able to find the counts by apiname

When asking for help debugging a specific issue you've encountered following existing instructions, you may get a better response by emailing google-stackdriver-discussion#googlegroups.com .
As outlined in Logs-based Metric Labels, you should specify the appropriate capture group to extract the value of the label.
You can then see the time series for the logs-based metric you've created (see https://cloud.google.com/monitoring/api/troubleshooting for how to query the raw data). It's likely that your regular expression is not matching exactly what you think it's matching, and you are always getting an empty value for the API_Name label. One suspect is the escaped \? in your pattern — according to the RE2 syntax, ? should not be escaped.

How to provide filter tab in timelion charts?

I am trying out some timelion visualizations in Kibana. In it I am not sure how to provide filter tab for the data.
For example, yearly country population data and filter tab to filter it based on zone and state.
Usually a timelion expression is just like ".es()" and some functions which can be appended to it like
.es(*).bars().label("Population")
I don't want to specify filter under ".es(q=???)" as this will make the filter static and the user won't be able to use filtering directly. ( In this case, every time user has to go to edit timelion window and edit filter there.)
you can specify a lucene query string as the q argument to .es() as in
.es(q=field:value)
That query string would only affect this time series and not interfere with the rest of your dashboard.

How to list unique values of a particular field in Kibana

I am having a field named rpc in my elasticsearch database and I am displaying it using Kibana. When I search in search bar of kibana like:
rpc:*
It display all the values of rpc field but I want to have only those value to be displayed which are unique.
I have been playing around with Kibana4 since a couple of weeks now. I find it intuitive and simple and the experience has been great till now. Following your question, I tried getting unique results via a Data Table visualization. Why? Because I personally find it easier to understand. Following are the steps:
1. Get unique count
Create the visualization (Visualize -> Data Table). First lets get
the count of how many unique entries we have for a particular field
(We will use this in the later part for verification). I'm using
clientip.raw but as I see, it will work just fine with any friendly
field name too.
2. Set the aggregation right
Set you aggregation back to count and have a Split Rows as follows. Not doing this will give you count 1 for each field value (since it is looking for unique counts) when you populate the table. Noteworthy part is setting the Top field to 0. Because Kibana won't let you enter anything else than a digit (Obviously!). This was the tricky part. Hit Apply and you'll get the results. Unique field values and the count of each of them.
3. Verification:
Going to the last page of the table, we see there are exactly 543 results. This is how I know it works.
What Next?
You save this visualization and add it to a Dashboard. There you can always check the request, query, response and other stats.
Just an addition to the above mathakoot answer.
For the user of newer version (which do not allow bucket size of 0 anymore) just set a value greater than the maximum number of result
And report the value in the Options>Per Page field
I am using Kibana 6 so the UI looks a bit different than the older answers here.
Here is what worked for me
Create a visualization from your query, I used a line graph type (don't think it matters)
Under Data, set metrics aggregation = "Unique Count" and set field to your field.
Set x-axis aggregation = "Terms" and set field to your field.
Set Size > your number of records
Under Metrics and Axes, disable drawing of the graph, circles, and labels (this really helps the UI not lag)
Run query and then click "Inspect" and download CSV
Data
Metrics & Axes
I wanted to achieve something similar but I'm stuck with Kibana 3.1.
I simply added a panel of type "TERMS" and configured its Field = User-agent and left everything else on default values. This gave me a nice bar chart with one bar for each User-agent.

Kibana i see Indices and fields but cannot Chart or Visualize

I curled the sample bank data to elasticsearch. On Kibana I see under the Indices bank and on visualize all the fields (age, balance, etc.) on the left but cannot see charts on the right. It always says No Results Found. On the left I selected Y-Axis - Agg as Average and Field as Balance and X-Axis Agg as Terms and Field as Age, all from drop downs. Then I used the APPLY action. No error is displayed, but neither is a chart.
What am I doing wrong here? Using curl I can check the elastic search and see that the data exists. No matter what I do, I do not see any logging in the elasticsearch logs under /usr/share/elasticsearch/logs.
I don't know if you figured this out or not but I had the exact same problem. I was using a mapping type that did not contain the field I was trying to visualize. Make sure the _type field contains a mapping with the correct indexed fields.
When setting up my initial index patterns, I glossed over specifying the 'Default timestamp' field, and the UI didn't insist on having one. The fix was to delete my index patterns and re-create them them, with the specified timestamp field. Everything snapped into place.

Generate heatmap in Kibana?

Does anyone know of a way to generate heatmaps in Kibana?
What I'm looking for is something similar to the clusters in bettermap, but continuous (and color-coded).
The only prerequisite is to have a geoip.location field.
If you're using an log which provide the requester origin IP you can easily get the Longitude, Latitude and then convert those values to the required geoip.coordinates field, and then the location
In kibana 4 beta:
open the Visualize tab
select tile map object
in the metrics value select the desired criteria from the drop down list, e.g. unique count
select the relevant field, e.g. hostip
in the buckets select Geo Coordinates
in the field select geoip.location
select the require percision (this might be important if you don't have a lot of data)
select the view option, you can toggle between change in color or size of circle
BTW, if you're using logstash to send the request to elasticsearch you can use the dns filter to reverse IP to coordinates
logstash dns filter
Heatmap support for Kibana 4 is on the way - and it's looking good.
Apparently the delay is that is has to be rewritten slightly to use SVG rather than it's current approach.
https://github.com/elastic/kibana/issues/1265
In Kibana 4, the index field has to be explicity defined as a geo_ip type in your mapping. Kibana 3 was able to correctly interpret floats etc. as coordinates, but as of now 4 does not. Once you change it you will have to reindex your data, and it should be all set.
