I am having an issue with trying to get logs on a linux server using filebeat to be delivered to my ELK server.
They are both on the same network, I can ping each server and I can telnet from the client server to the ELK server using port 5044.
Here are the config files from the ELK server 30-elasticsearch-output.conf
prospectors:
# Each - is a prospector. Below are the prospector specific configurations
-
# Paths that should be crawled and fetched. Glob based paths.
# To fetch all ".log" files from a specific level of subdirectories
# /var/log//.log can be used.
# For each file found under this path, a harvester is started.
# Make sure not file is defined twice as this can lead to unexpected behaviour.
paths:
- /var/log/auth.log
- /var/log/syslog
- /opt/ultraesb/logs/ultraesb.log #- c:\programdata\elasticsearch\logs*
# Configure the file encoding for reading files with international characters
# following the W3C recommendation for HTML5 (http://www.w3.org/TR/encoding).
# Some sample encodings:
# plain, utf-8, utf-16be-bom, utf-16be, utf-16le, big5, gb18030, gbk,
# hz-gb-2312, euc-kr, euc-jp, iso-2022-jp, shift-jis, ...
#encoding: plain
# Type of the files. Based on this the way the file is read is decided.
# The different types cannot be mixed in one prospector
#
# Possible options are:
# * log: Reads every line of the log file (default)
# * stdin: Reads the standard in
input_type: log
# Exclude lines. A list of regular expressions to match. It drops the lines that are
# matching any regular expression from the list. The include_lines is called before
# exclude_lines. By default, no lines are dropped.
# 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. The include_lines is called before
# exclude_lines. By default, all the lines are exported.
# 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 field can be freely picked
# to add additional information to the crawled log files for filtering
#fields:
# level: debug
# review: 1
# Set to true to store the additional fields as top level fields instead
# of under the "fields" sub-dictionary. In case of name conflicts with the
# fields added by Filebeat itself, the custom fields overwrite the default
# fields.
#fields_under_root: false
# Ignore files which were modified more then the defined timespan in the past.
# In case all files on your system must be read you can set this value very large.
# Time strings like 2h (2 hours), 5m (5 minutes) can be used.
#ignore_older: 0
# Close older closes the file handler for which were not modified
# for longer then close_older
# Time strings like 2h (2 hours), 5m (5 minutes) can be used.
#close_older: 1h
# Type to be published in the 'type' field. For Elasticsearch output,
# the type defines the document type these entries should be stored
# in. Default: log
document_type: syslog
# Scan frequency in seconds.
# How often these files should be checked for changes. In case it is set
# to 0s, it is done as often as possible. Default: 10s
#scan_frequency: 10s
# Defines the buffer size every harvester uses when fetching the file
#harvester_buffer_size: 16384
# Maximum number of bytes a single log event can have
# All bytes after max_bytes are discarded and not sent. The default is 10MB.
# This is especially useful for multiline log messages which can get large.
#max_bytes: 10485760
# Mutiline can be used for log messages spanning multiple lines. This is common
# for Java Stack Traces or C-Line Continuation
#multiline:
# The regexp Pattern that has to be matched. The example pattern matches all lines starting with [
#pattern: ^\[
# Defines if the pattern set under pattern should be negated or not. Default is false.
#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
#match: after
# The maximum number of lines that are combined to one event.
# In case there are more the max_lines the additional lines are discarded.
# Default is 500
#max_lines: 500
# After the defined timeout, an multiline event is sent even if no new pattern was found to start a new event
# Default is 5s.
#timeout: 5s
# Setting tail_files to true means filebeat starts readding new files at the end
# instead of the beginning. If this is used in combination with log rotation
# this can mean that the first entries of a new file are skipped.
#tail_files: false
Backoff values define how agressively filebeat crawls new files for updates
# The default values can be used in most cases. Backoff defines how long it is waited
# to check a file again after EOF is reached. Default is 1s which means the file
# is checked every second if new lines were added. This leads to a near real time crawling.
# Every time a new line appears, backoff is reset to the initial value.
#backoff: 1s
# Max backoff defines what the maximum backoff time is. After having backed off multiple times
# from checking the files, the waiting time will never exceed max_backoff idenependent of the
# backoff factor. Having it set to 10s means in the worst case a new line can be added to a log
# file after having backed off multiple times, it takes a maximum of 10s to read the new line
#max_backoff: 10s
# The backoff factor defines how fast the algorithm backs off. The bigger the backoff factor,
# the faster the max_backoff value is reached. If this value is set to 1, no backoff will happen.
# The backoff value will be multiplied each time with the backoff_factor until max_backoff is reached
#backoff_factor: 2
# This option closes a file, as soon as the file name changes.
# This config option is recommended on windows only. Filebeat keeps the files it's reading open. This can cause
# issues when the file is removed, as the file will not be fully removed until also Filebeat closes
# the reading. Filebeat closes the file handler after ignore_older. During this time no new file with the
# same name can be created. Turning this feature on the other hand can lead to loss of data
# on rotate files. It can happen that after file rotation the beginning of the new
# file is skipped, as the reading starts at the end. We recommend to leave this option on false
# but lower the ignore_older value to release files faster.
#force_close_files: false
# Additional prospector
#-
# Configuration to use stdin input
#input_type: stdin
General filebeat configuration options
Event count spool threshold - forces network flush if exceeded
#spool_size: 2048
Enable async publisher pipeline in filebeat (Experimental!)
#publish_async: false
Defines how often the spooler is flushed. After idle_timeout the spooler is
Flush even though spool_size is not reached.
#idle_timeout: 5s
Name of the registry file. Per default it is put in the current working
directory. In case the working directory is changed after when running
filebeat again, indexing starts from the beginning again.
registry_file: /var/lib/filebeat/registry
Full Path to directory with additional prospector configuration files. Each file must end with .yml
These config files must have the full filebeat config part inside, but only
the prospector part is processed. All global options like spool_size are ignored.
The config_dir MUST point to a different directory then where the main filebeat config file is in.
Configure what outputs to use when sending the data collected by the beat.
Multiple outputs may be used.

File as output
#file:
# Path to the directory where to save the generated files. The option is mandatory. #path: "/tmp/filebeat"
# Name of the generated files. The default is `filebeat` and it generates files: `filebeat`, `filebeat.1`, `filebeat.2`, etc.
#filename: filebeat

There are three options for the log ouput: syslog, file, stderr.
Under Windos systems, the log files are per default sent to the file output,
under all other system per default to syslog.
logging:
Send all logging output to syslog. On Windows default is false, otherwise
default is true.
#to_syslog: true
Write all logging output to files. Beats automatically rotate files if rotateeverybytes
limit is reached.
#to_files: false
To enable logging to files, to_files option has to be set to true
files:
# The directory where the log files will written to. #path: /var/log/mybeat
# The name of the files where the logs are written to.
#name: mybeat
# Configure log file size limit. If limit is reached, log file will be
# automatically rotated
rotateeverybytes: 10485760 # = 10MB
# Number of rotated log files to keep. Oldest files will be deleted first.
#keepfiles: 7
Enable debug output for selected components. To enable all selectors use ["*"]
Other available selectors are beat, publish, service
Multiple selectors can be chained.
#selectors: [ ]
Sets log level. The default log level is error.
Available log levels are: critical, error, warning, info, debug
Based on those logs it looks like you have it configured to output to elasticsearch and not logstash. Double check your output configuration and make sure have commented out the output.elasticsearch section.
