Will Foster 21f1f28ab3 Add ELK stack and ELK client Ansible playbooks.
Fixes for this patchset:
- split out elk-openstack-client.yml to match what's done elsewhere

Fixes for patchset #11:
- split out filebeat into separate role for openstack clients
- update README.md to use elk-openstack-client.yml for this purpose
- cleanup filebeat.yml.j2 to use correct syntax (no need for " anymore)

Fixes for patchset #10:
- add SELinux boolean "httpd_can_network_connect"
- add libsemanage-python package dependency for booleans

Fixes for patchset #9:
- fix for RHEL7 clients, we need to specify remote EPEL rpm
- RHEL7 clients need rpm_key module to import EPEL GPG key
- switch to using uri module instead of curl for checking elasticsearch indices
- add python-httplib2 dependency (needed for uri module)
- use curl -XPOST instead of PUT for filebeat index template in elasticsearch

Fixes from patchset #7
- remove unneeded rpm usage, switch to yum module
- add logic to heapsize tuning so systems > 64G of memory will
  never exceed the 32G recommended heapsize
- logic fix for prepopulating local logs into logstash
- remove elasticsearch.yml, rpm provides this and we're not
  customizing it yet

Fixes from patchset #6:
- use yum repo Ansible module where we can
- remove unecessary EPEL installation (only nginx needs it)
- disable EPEL repo after installation to avoid OpenStack breakage

This adds:

(ELK Server)
- Automated ELK stack deployment
- SSL client generation
- Heap size tuning (1/2 of available memory)
- Firewall port additions (depending on active or not)
  - Supports either firewalld or iptables-services
- Additional upstream Filebeat Kibana dashboards

(ELK Client)
- Sets up filebeat with appropriate SSL certificates
  - utilizes both hostnames and SubjectAltName support (for environments without
    DNS services).

(Usage)

ansible-playbook -i hosts install/elk.yml
ansible-playbook -i hosts install/elk-client.yml --extra-vars 'elk_server=X.X.X.X'

################### Filebeat Configuration Example #########################
############################# Filebeat ######################################
filebeat:
# List of prospectors to fetch data.
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/*.log
- /var/log/messages

# 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
# 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
# Time strings like 2h (2 hours), 5m (5 minutes) can be used.
#ignore_older: 24h
# 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
# 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.
