Hi, I new to go language development. In my product development, I want to see the logger in kibana dashboard. I installed elastic search,logstach, kibana and file beat. but unable to get logger in kibana dashboard. Can you tell me the how can I implement?. Thank you.
Hi @vinodh023,
Could you please explain little bit more that what you want to do or what is your use case?

I want see my go language application logs in kibana. So, I installed elastic search, logstach, kibana and file beat. But, not able see my logs in kibana. what can do.
Hi @vinodh023,
Have you set the same path in filebeat/logstash to get the logs on kibana dashboard??
If you have set and facing any issue you can share you config file and log here so that i can see the issue and provide some solution on that.

How can I set path in filebeat/lgostach ?. Path means can set any port number or go language src folder name? Thank you.
Ho @vinodh023,
Yes, These both are possible.
For path only:
Go to filebeat.yml file available in /etc/filebeat/ folder and set prospector setting and configure the elasticsearch or logstash o/p to send that logs and configure the kibana with elasticsearch in /etc/kibana/kibana.yml file and restart all service and you will get all logs on kibana dashboard.
If you want to go with port you can use logstashh i/p plugin for the same.

**My file beat like this** :
Filebeat Configuration Example
https://www.elastic.co/guide/en/beats/filebeat/index.html
#=========================== Filebeat inputs =============================
filebeat.inputs:
Each - is an input. Most options can be set at the input level, so
you can use different inputs for various configurations.
Below are the input specific configurations.
-
type: log
Change to true to enable this input configuration.
enabled: true
Paths that should be crawled and fetched. Glob based paths.
paths:
- /var/log/*.log
#- c:\programdata\elasticsearch\logs*
Exclude lines. A list of regular expressions to match. It drops the lines that are
matching any regular expression from the list.
#exclude_lines: ['^DBG']
Include lines. A list of regular expressions to match. It exports the lines that are
matching any regular expression from the list.
#include_lines: ['^ERR', '^WARN']
Exclude files. A list of regular expressions to match. Filebeat drops the files that
are matching any regular expression from the list. By default, no files are dropped.
#exclude_files: ['.gz$']
Optional additional fields. These fields can be freely picked
to add additional information to the crawled log files for filtering
#fields:
level: debug
review: 1
Multiline options
Multiline can be used for log messages spanning multiple lines. This is common
for Java Stack Traces or C-Line Continuation
The regexp Pattern that has to be matched. The example pattern matches all lines starting with [
#multiline.pattern: ^[
Defines if the pattern set under pattern should be negated or not. Default is false.
#multiline.negate: false
Match can be set to "after" or "before". It is used to define if lines should be append to a pattern
that was (not) matched before or after or as long as a pattern is not matched based on negate.
Note: After is the equivalent to previous and before is the equivalent to to next in Logstash
#multiline.match: after
- /var/log/*.log
#============================= Filebeat modules ===============================
filebeat.config.modules:
Glob pattern for configuration loading
path: ${path.config}/modules.d/*.yml
Set to true to enable config reloading
reload.enabled: false
Period on which files under path should be checked for changes
#reload.period: 10s
#==================== Elasticsearch template setting ==========================
setup.template.settings:
index.number_of_shards: 3
#index.codec: best_compression
#_source.enabled: false
#================================ General =====================================
The name of the shipper that publishes the network data. It can be used to group
all the transactions sent by a single shipper in the web interface.
#name:
The tags of the shipper are included in their own field with each
transaction published.
#tags: ["service-X", "web-tier"]
Optional fields that you can specify to add additional information to the
output.
#fields:
env: staging
#============================== Dashboards =====================================
These settings control loading the sample dashboards to the Kibana index. Loading
the dashboards is disabled by default and can be enabled either by setting the
options here, or by using the -setup CLI flag or the setup command.
#setup.dashboards.enabled: false
The URL from where to download the dashboards archive. By default this URL
has a value which is computed based on the Beat name and version. For released
versions, this URL points to the dashboard archive on the artifacts.elastic.co
website.
#setup.dashboards.url:
#============================== Kibana =====================================
Starting with Beats version 6.0.0, the dashboards are loaded via the Kibana API.
This requires a Kibana endpoint configuration.
setup.kibana:
Kibana Host
Scheme and port can be left out and will be set to the default (http and 5601)
In case you specify and additional path, the scheme is required: http://localhost:5601/path
IPv6 addresses should always be defined as: https://[2001:db8::1]:5601
#host: "localhost:5601"
Kibana Space ID
ID of the Kibana Space into which the dashboards should be loaded. By default,
the Default Space will be used.
#space.id:
#============================= Elastic Cloud ==================================
These settings simplify using filebeat with the Elastic Cloud (https://cloud.elastic.co/).
The cloud.id setting overwrites the output.elasticsearch.hosts and
setup.kibana.host options.
You can find the cloud.id in the Elastic Cloud web UI.
#cloud.id:
The cloud.auth setting overwrites the output.elasticsearch.username and
output.elasticsearch.password settings. The format is <user>:<pass>.
#cloud.auth:
#================================ Outputs =====================================
Configure what output to use when sending the data collected by the beat.
#-------------------------- Elasticsearch output ------------------------------
#output.elasticsearch:
Array of hosts to connect to.
#hosts: ["localhost:9200"]
Enabled ilm (beta) to use index lifecycle management instead daily indices.
#ilm.enabled: false
Optional protocol and basic auth credentials.
#protocol: "https"
#username: "elastic"
#password: "changeme"
#----------------------------- Logstash output --------------------------------
output.logstash:
The Logstash hosts
hosts: ["localhost:5044"]
Optional SSL. By default is off.
List of root certificates for HTTPS server verifications
#ssl.certificate_authorities: ["/etc/pki/root/ca.pem"]
Certificate for SSL client authentication
#ssl.certificate: "/etc/pki/client/cert.pem"
Client Certificate Key
#ssl.key: "/etc/pki/client/cert.key"
#================================ Processors =====================================
Configure processors to enhance or manipulate events generated by the beat.
processors:
- add_host_metadata: ~
- add_cloud_metadata: ~
At debug level, you can selectively enable logging only for some components.
To enable all selectors use ["*"]. Examples of other selectors are "beat",
"publish", "service".
#logging.selectors: ["*"]
#xpack.monitoring.elasticsearch:
is this Okay?

Hi @vinodh023,
First, you need to specify the log file path in below section.
quote=""]
/var/log/*.log
[/quote]
After that you need to configure elasticsearch as o/p in below section uncomment and provide IP and port and restart the service.

Hi, I un commented the
hosts: ["localhost:9200"]
How can i specify log file path?
paths:
- /var/log/*.log
#- c:\programdata\elasticsearch\logs*
instead of * - /var/log/*.log can I add any value like - /var/log/golanglog.log
Can you give any reference tutorial or any example related to go language?
Hi @vinodh023,
i Understood you are using logstash as o/p.
Yes you can specify the same and restart filebeat service.
Br,
Harsh Bajaj
Hi @vinodh023,
This is not only for Go lang you can specify any path as you asked in above query and filebeat will send this log to your logstash directly.
I think restart commands like
sudo /etc/initi.d/filebeat start
sudo /etc/initi.d/filebeat stop
sudo /etc/initi.d/filebeat restart
Okay Can I keep these file without any changes?
paths:
- /var/log/.log
#- c:\programdata\elasticsearch\logs
I used this command : sudo service filebeat restart. but no changes effected.
You didn't specify any path in below section.
Br,
Harsh Bajaj
What i kept there?
