Hello everyone,
I have been facing a problem here configuring Filebeat. I keep on having failures. below is my configuration and log.
```
#=========================== Filebeat inputs =============================
filebeat.inputs:
- type: log
enabled: true
paths: C:\ProgramData\Elastic\Elasticsearch\logs\*.log
#============================= Filebeat modules ===============================
filebeat.config.modules:
path: ${path.config}/modules.d/*.yml
reload.enabled: false
#==================== Elasticsearch template setting ==========================
setup.template.settings:
index.number_of_shards: 1
#index.codec: best_compression
#_source.enabled: false
#============================== Kibana =====================================
setup.kibana:
#================================ 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"]
processors:
- add_host_metadata: ~

```
