Exclude file from being processed

[bdobsonca]

Hello, I have /var/log/elasticsearch/gc.log.0.current currently flooding my logs. I would like to know the best way to exclude this? I am running Filebeats 6.4.2.

I have tried: exclude_files with the following:

['\.current$']

but they continue.

I would love to know how to properly submit the loglines as well as I've clearly missed something

Could you please share your full config formatted using </>? The regex you've pasted here seems to be correct. So there must be other problems somewhere in your config.

[bdobsonca]

Config included below:

#=========================== 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

  #exclude_lines: ['^DBG']
  include_lines: ['^ERR', '^WARN']
  exclude_files: ['\.current']

  ### Multiline options

  multiline.pattern: ^\[
  multiline.negate: false
  multiline.match: after


#============================= 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: http://kibana.apimsvc.xx.com

#============================== 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: "kibana.apimsvc.xx.com:5601"

#============================= 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: ["kibana.apimsvc.xx.com:9200"]

  # Optional protocol and basic auth credentials.
  #protocol: "https"
  #username: "elastic"
  #password: "changeme"

#----------------------------- Logstash output --------------------------------
output.logstash:
  # The Logstash hosts
  hosts: ["kibana.apimsvc.ca.com:5044"]

  # Optional SSL. By default is off.
  # List of root certificates for HTTPS server verifications
  ssl.certificate_authorities: ["/etc/pki/tls/certs/logstash-forwarder.crt"]

  # Certificate for SSL client authentication
  #ssl.certificate: "/etc/pki/client/cert.pem"

  # Client Certificate Key
  #ssl.key: "/etc/pki/client/cert.key"

#================================ Logging =====================================

# Sets log level. The default log level is info.
# Available log levels are: error, warning, info, debug
#logging.level: debug

# 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 ===============================
# filebeat can export internal metrics to a central Elasticsearch monitoring
# cluster.  This requires xpack monitoring to be enabled in Elasticsearch.  The
# reporting is disabled by default.

# Set to true to enable the monitoring reporter.
#xpack.monitoring.enabled: true

# Uncomment to send the metrics to Elasticsearch. Most settings from the
# Elasticsearch output are accepted here as well. Any setting that is not set is
# automatically inherited from the Elasticsearch output configuration, so if you
# have the Elasticsearch output configured, you can simply uncomment the
# following line.
#xpack.monitoring.elasticsearch:

So I turned on debug and it looks like it's still trying to exclude the default .gz instead of what I have:

|2018-10-03T16:19:40.970-0400|DEBUG|[input]|log/input.go:147|exclude_files: [(?-s:.)gz(?-m:$)]. Number of stats: 21|
|---|---|---|---|---|
|2018-10-03T16:19:40.977-0400|DEBUG|[input]|log/input.go:147|exclude_files: [(?-s:.)gz(?-m:$)]. Number of stats: 21|
|2018-10-03T16:19:40.983-0400|DEBUG|[input]|log/input.go:147|exclude_files: [(?-s:.)gz(?-m:$)]. Number of stats: 21|

Sorry for this I just wanted to add more information, I can see via debug now:

exclude_files: [(?-s:.)current(?-m:$)]. Number of stats: 21

This is after changing it to:

exclude_files: ['.*.current$']

However the logs still show up. Trying to exclude /var/log/elasticsearch/gc.log.0.current and all variations.

Could you provide more logs?
Are you sure this is the config which runs? According to the path configuration you provided:

paths:
  - /var/log/*.log

/var/log/elasticsearch/gc.log.0.current is not going to be opened, because it does not match the pattern.
