Source log sample from message field:
{"log":"2022/02/15 22:47:07 insert into public.logs (time, level, message, hostname, loggerUID, appmodule) values ('2022-02-15 22:47:07.494330952','ERROR','GetRequestsByUserv2 :pq: column \"rr.requestdate\" must appear in the GROUP BY clause or be used in an aggregate function','ef005e6da6f6','ba282127-6ef6-4238-9287-d7127a8d1996','eReturn')\n","stream":"stderr","time":"2022-02-15T14:47:07.495133571Z"}
Trying to extract " level: ERROR " as separate field from above log using ingest pipelines in Elastic so that it can be segregated based on the level of the logs such as ERROR,WARNING,INFO
Tried with split processor, but was not able to get the desired output. Any help would be appreciated.
You can use the grok processor using its syntax for regex:
%{DATA:preerror} values \('%{DATA:date}','%{DATA:error}'%{GREEDYDATA:posterror}
Then you can remove the fields preerror, date, posterror that you don't need.

Problem
I am trying to build a dashboard in elastic with a table to monitor job runs.
I want to have per run the minimum timestamp (ie. job start) and the number of processed messages. The minimum timestamp is my problem, I can't seem to get it.
What I have done
All my log lines have as (relevant) fields: #timestamp, nb_messages, run_id. run_id is unique per run, and a run creates multiple log lines.
I create a dashboard, add a TSVB panel, and select Table.
I use run_id as the field to group by.
I can use max(nb_message) in my table without issue.
But if I use min(#timestamp), or any other aggregation than count, I just get a -.
I first tried with a lens instead of a TSVB panel, and I had the same issue, but with as message: To use this function, select a different field.
I can confirm in the index that logging.timestamp has date for type.
Question
Is there a way to use the timestamp as metric?
I would use a "normal" data table visualization (navigate through Aggregation based option in the Visualization menu if you're using the latest version of Kibana) instead of the TSVB. There, the default metric is count representing the amount of events of the index pattern in the selected time range. You can use the min metric on the #timestamp field and aggregate/group your data as you want.
The preliminary is of course that the selected index pattern contains an #timestamp field.
I hope I could help you.
I have the following filter in Cloud Logging that shows me all logs from a particular instance:
(resource.type="gce_instance" AND resource.labels.instance_id="***") OR (resource.type="global" AND jsonPayload.instance.id="***")
In this set, I want to search for a value in all fields. By looking at the documentation https://cloud.google.com/logging/docs/view/advanced-queries#searching-examples I found that I can write a simple word unicorn in the query fields and it will search in all fields. It works, but it searches in all my logs. But I want to search in the filtered logs set only, not across all logs in Cloud Logging. I want to get all rows containing the word failed and tried this:
((resource.type="gce_instance" AND resource.labels.instance_id="***") OR (resource.type="global" AND jsonPayload.instance.id="***")) and failed
But id doesn't work. How can I search in all fields while already having a filter?
Try to run the query formatting this way the last part:
((resource.type="gce_instance" AND resource.labels.instance_id="***") OR
(resource.type="global" AND jsonPayload.instance.id="***")) AND "failed"
Cheers,
I want to create a Kibana metric for the unique users visiting my site.
I have an index collecting logs from a service in format
<date> <user1#gmail.com> - <log message> <client>
and I want to count unique user emails ignoring the rest of the fields.
Is it possible to do such a regex via some of the aggregations? Currently I was able to find only unique count based on some specific field which is not an option for me.
You can create a separate field first:
Either by using kibana scripted fields.
Or by using logstash mutate filter plugin.
And then you can apply terms aggregation on data table visualization to achieve this.
sample message - 111,222,333,444,555,val1in6th,val2in6th,777
The sixth column contains a value consisting of commas (val1in6th,val2in6th is a sample value of 6th column).
When I use a simple csv filter this message is getting converted to 8 fields. I want to be able to tell the filter that val1in6th,val2in6th should be treated as a single value and placed as the value of 6th column (its okay not to have comma between val1in6th and val2in6th when placed as the output as 6th column).
change your plugin, no more the csv one but grok filter - doc here.
Then you use a debugger to create a parser for your lines - like this one: https://grokdebug.herokuapp.com/
For your lines you could use this grok expression:
%{WORD:FIELD1},%{WORD:FIELD2},%{WORD:FIELD3},%{WORD:FIELD4},%{WORD:FIELD5},%{GREEDYDATA:FIELD6}
or :
%{INT:FIELD1},%{INT:FIELD2},%{INT:FIELD3},%{INT:FIELD4},%{INT:FIELD5},%{GREEDYDATA:FIELD6}
It changes the datatypes in elastic of the firsts 5 fields.
To know about parse csv with grok filter in elastic you could use this es official blog guide, it is explained how to use grok with ingestion pipeline, but it is the same with logstash
Using Kibana, is it possible to display one row of data which is a summary of other rows?
This is our requirement:
Given an entry in an index with the following structure:
string requestId
boolean raisedException
boolean requiredExternalLookup
We want to create a tabular output with the following structure
requestId numberRaisedException numberNoException numberRequiredLookup
So, if there were three rows (or entries) in the index for the same request id, two where an exception was raised, the output may look like this:
requestId numberRaisedException numberNoException numberRequiredLookup
REQUEST_123 2 1 3
Presumably the correct Kibana visualization widget to represent this would be a Data Table. But how in Kibana would one create a row like the above which is a summary of several rows, somewhat akin to a sql GROUP BY clause. Is it at all possible?
You can probably do this with 'scripted_fields', but the status of the 'scripted_fields' feature in kibana isn't clear. I think it was recently blocked in kibana due to security issues - Leaving this open is dangerous since you can do anything.
If you have access to your elasticsearch cluster then you might be able to create the field on your elasticsearch index.
