Sample filebeat.yml file

#=============Filebeat prospectors ===============

filebeat.prospectors:

# Here we can define multiple prospectors and shipping method and rules  as per #requirement and if need to read logs from multiple file from same patter directory #location can use regular pattern also.

#Filebeat support only two types of input_type log and stdin

##############input type logs configuration#####################

- input_type: log

# Paths of the files from where logs will read and use regular expression if need to read #from multiple files
paths:
- /opt/app/app1/logs/app1-debug*.log*
# make this fields_under_root as true if you want filebeat json out for read files in root.
fields_under_root: true

### Multiline configuration for handeling stacktrace, Object, XML etc if that is the case #and multiline is enabled with below configuration will shipped output for these case in #multiline

# The regexp Pattern that has to be matched. The example pattern matches all lines #starting with [DEBUG,ALERT,TRACE,WARNING log level that can be customize #according to your logs line format
#multiline.pattern: '^\[([Aa]lert|ALERT|[Tt]race|TRACE|[Dd]ebug|DEBUG|[Nn]otice|NOTICE|[Ii]nfo|INFO|[Ww]arn?(?:ing)?|WARN?(?:ING)?|[Ee]rr?(?:or)?|ERR?(?:OR)?|[Cc]rit?(?:ical)?|CRIT?(?:ICAL)?|[Ff]atal|FATAL|[Ss]evere|SEVERE|EMERG(?:ENCY)?|[Ee]merg(?:ency)?)'

# if you will set this max line after these number of multiline all will ignore
#multiline.max_lines: 50
#=========Logstash Output Configuration=======================
output.logstash:
# Below enable flag is for enable or disable output module will discuss more on filebeat #module section.
#enabled: true

#  Here mentioned all your logstash server host and port to publish events. Default port #for logstash is 5044 if Logstash listener start with different port then use same here.
#hosts: ["logstashserver:5044"]

# It shows no of worker will run for each configure Logstash host.

#Filebeat provide gzip compression level which varies from 1 to 9. As compression level #increase processing speed will reduce but network speed increase.By default #compression level disable and value is 0.
#compression_level: 3

# Default value is false.  If set to true will check status of hosts if unresponsive will send #to another available host. if false filebeat will select random host and send events to it.
#loadbalance: true

# Default value is 0 means pipeline disabled. Configure value decide of pipeline  batches #to send to logstash asynchronously and wait for response. If pipeline value is written #means output will blocking.
#pipelining: 0

#Filebeat use SOCKS5 protocol to communicate with Logstash servers. If any proxy #configure for this protocol on server end then we can overcome by setting below #details.

# SOCKS5 proxy URL
#proxy_url: socks5://userid:pwd@socks5-server:2233

# Default value is false means resolve host name resolution on  proxy server. If value is #set as true Logstash host name resolution locally for proxy.

# Configure SSL setting id required for Logstash broker if SSL is configured
#ssl.enabled: true

# Optional SSL configuration options. SSL is off by default.
# List of root certificates for HTTPS server verifications

#SSK configuration is Optional and OFF by default . It required for server verification if #HTTPS root certificate .
#ssl.certificate_authorities: ["/app/pki/root/ca.pem"]

#Default value is full. SSL configuration verfication mode is required if SSL is configured #We can use value as 'none' for testing purpose but in this mode it can accept any #certificate.
#ssl.verification_mode: full

# List of supported/valid TLS versions. By default all TLS versions 1.0 up to
# 1.2 are enabled.

#By Default  it support all TLS versions after 1.0 to 1.2. We can also mentioned version in #below array
#ssl.supported_protocols: [TLSv1.0, TLSv1.1, TLSv1.2]

# Define path for certificate for SSL
#ssl.certificate: "/etc/pki/client/cert.pem"

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

# If data is configured and shipped encrypted form. Need to add passphrase for #decrypting the Certificate Key otherwise optional
#ssl.key_passphrase: ''

# Configure encryption cipher suites to be used for SSL connections
#ssl.cipher_suites: []

# Configure encryption curve types for ECDHE based cipher suites
#ssl.curve_types: []
#====================Logging ==============================

# Default log level is info if set above or below will record top this hierarchy #automatically. Available log levels are: critical, error, warning, info, debug

logging.level: debug
# Possible values for selectors are "beat", "publish" and  "service" if you want to enable #for all select value as "*". This selector decide on command line when  start filebeat.
logging.selectors: ["*"]

# The default value is false.If make it true will send out put to syslog.
