Thank you for tour post Badger. How do I fix that ? Do I have to configure pipelines in pipeline management UI ? Can this be configured in logstash.yml file ? Something else?
That enables centralized configuration management. If you do not want it enabled then do not set it. Read the documentation I linked to.
Ok so I followed the documentation the best I could, in both cases I am still getting error.
Case1: using centralized management. I have created following logstash pipeline using Kibana UI
input {
beats {
port => 5044
type => "log"
host => "0.0.0.0"
}
}
output {
elasticsearch {
hosts => "https://xxxxxx:9243"
user => "elastic"
password => "xxxxxxr"
index => "%{[@metadata][beat]}-%{+yyyy.ww}"
#document_type => "%{[@metadata][type]}"
}
}
I am getting following error

When the elasticsearch output connects to that it is getting HTML. It expects to get JSON, which is what elasticsearch would return. Have you pointed the output at a kibana instance?
"https://xxxxxx:9243"
I use Cloud ID, should I use Kibana cluster ID instead ?
Sorry, I have never used cloud instances for elastic so I am not able to answer.
Np. I understand. Thanks for trying. Can anyone else advise?
The problem is definitely somewhere in the conf file.
Perhaps take a look at this thread
It refers to Packetbeat but the concept / code is the same.
Assuming you just want to use log stash as the pass through then Your logstash conf file should look like this
################################################
# beats->logstash->es default config.

input {
beats {
port => 5044
}
}
output {

worked like a charm, big thank you Stephen
Hi Stephen and all, I bumped into another problem now.... I am able to see data and create indexes but I am unable to see hosts and populated even most basic charts/dashboards. Here are errors I am getting:
- failed to run search on hosts kpi hosts (400)
- failed to run search on hosts kpi unique ips (400)
- failed to run search on all hosts (400)
index": "winlogbeat-7.13.0",
"node": "oArFASb5Qzit5aB33VdcsQ",
"reason": {
"type": "illegal_argument_exception",
"reason": "Text fields are not optimised for operations that require per-document field data like aggregations and sorting, so these operations are disabled by default. Please use a keyword field instead. Alternatively, set fielddata=true on [host.name] in order to load field data by uninverting the inverted index. Note that this can use significant memory."
Can you please advise ?
Looks like you did not run winlogbeat setup
first so the template was not loaded and thus the correct mapping was not applied. (It looks like you are using the default mapping)
You need to follow the steps I showed in that other thread... not just add the logstashconf and run...
I always suggest setup a beat direct to ES first ... see that it is working ... then put logstash in the middle.

That is a great suggestion, thank you. I will circle back to suggested articles.
I have been reading about this problem in a similar post
https://discuss.elastic.co/t/failed-to-log-events-to-logstash/234305
I have learned that if i am using Logstash output, I won't be able to manage/load indexes automatically ( with "setup -e" )
Therefore, I studied how to set it up manuall:
https://www.elastic.co/guide/en/beats/winlogbeat/current/winlogbeat-template.html#load-template-manually
but aggain here suggested command
PS > Invoke-RestMethod -Method Put -ContentType "application/json" -InFile winlogbeat.template.json -Uri http://localhost:9200/_template/winlogbeat-7.13.0
only shows how to export it to elastic on localhost. The question is how to export it to elastic cloud using logstash or manually?
See you are trying to make it difficult loading manually etc.. etc.. etc..
if you run
winlogbeat setup -e
When winlogbeat is pointed at Elastic Cloud everything will get set up.... everything, dashboard, template, ilm, ingest pipelines ... everything.... loading manually is not recommended by me.
Then put logstash in the middle. Unfortunately because you did not do this first you probably need to clean up the old indices
I can only make suggestions You can
Thanks Stephen, I really appreciate your help.
I have never thought about connecting Winlog to Elastic Cloud and running "setup -e" first (that's lack of experience). I thought that switching between ES cloud and logstash will break things.
Anyhow, before I break more stuff (this is why I am doing it on lab cluster before production) .....
If I understand correctly I need to edit my winlog .yml file and point it directly to ES cloud. In order to do so I need to comment out output for Logstash, uncomment Elastic with following entries
cloud_auth => "elastic:password"
cloud_id => "mycloud:dXMtZWFzdC0xLmF3cy5mb3VuZC5pbyRj......"
after this I just need to run "setup -e" and than set everything back to point to logstash.
Now.... the question is how do I clean up old indices ? Is there an API call that can help me with it?
https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-delete-index.html
Found this one, I hope it will work ...
I gave you step by step details here :
Just replace the word packetbeat
with winlogbeat
Solution:
So actually there is very little you need to do to make this all work, we will use Logstash as a pasthrough and let all the winlogbeat module do its work, ECS formating, Templates, GEO IP, Index Lifecycle Management, it will all be taken care of.
Here is what I recommend, try to resist the urge to make this more complex that it needs to be.
- One a single host Perform Steps 1 - 5 on the Winlogbeat Quckstart page for Elastic Search Service.This will setup Packetbeat and all the associated assets in Elasticsearch and Kibana.
Note Setup only needs to run Once whether you are setting up on 1 host or 1000 hosts, it just loads all the needs artifacts. and If you already did all this.. .and you still have the the cluster you don't even need to do it again.
- Now in the winlogbeat.yml comment out
cloud.id
andcloud.auth:
and configure the output section of winlogbeat to point to logstash. Comment out theoutput.elasticsearch:
section. Now Packetbeat is pointed to your on prem Logastash
output.logstash:
# The Logstash hosts
hosts: ["localhost:5044"]
...
- Setup Logstash. Below is the
logstash-beats-es.conf
that will support all the beats functionality. Logstash simply acts as a passthough, Packetbeat functionality will magically get passed through. - Start Logstash then start Packetbeat... take a look...data should start to flow exactly as it did when it was Packetbeat to Elastic Cloud direct.
- Deploy Packetbeat on other hosts. Configure to point at this Logstash.
Logstash Config for Beats Pass through.

}
to delete indices just go into Kibana and delete indices like this
GET _cat/indices/win-*/?v
DELETE winlogbeat-7.12.0-000001
You are genius my friend. I promise to read your suggestions next time before asking more questions.
I connected winlog directly with elastic and executed setup -e with no problems
I am not getting more errors. Host are showing up as they should. The only problem now is that logs are shown in wrong time (just hour is off).
Also, do I need to run setup -e for every single winlog computer/VM or was it only necessary once for the first winlog "agent"
From the previous post.... Perhaps read more carefully
Dates are stored in UTC inside elasticsearch and are shown in local time zone in kibana lots of posts on that.
If you have a time zone issue open a separate thread
Great. As always thank you.
Slightly different, more technical question but in the same scope.
With the setup I have (beat)-->(logstash)---(elastic cloud), is logstash expected to store any data locally? If yes, for how long? Since I am using it only to pass data from beats to elastic, what expected disk size I should assign to it?
Also, I tired setting up metric beats following your instructions and instructions from the guide, and I was not able to. It looks like metricbeat is able to successfully setup dashboards etc. it sends data out to elastic but most charts in dashboards are not working.
Host overview seems to be working fine (except of time)
Is metric beat setup procedure different than packet eat and wingbeat ?
https://www.elastic.co/guide/en/beats/metricbeat/7.13/metricbeat-installation-configuration.html
a) Logstash has a local persistent queue if you want one otherwise no local storage except in memory
b) That is not the right dashboard Look for [Metricbeat System] Overview ECS
(the one you are looking at is when you use Elastic Agent). Also you can look at the metrics APP.
c) All the setups are similiar
