Create a new index everyday with filebeat

[darshanky]

Hello Folks,

I am new to Elasticstack and trying to get my hear around. I have setup the single node elastic stack which runs the Kibana as well. I have a client that has file beat installed and sends logs to elasticsearh. The setup works perfectly fine.

I have apache module enabled in the file beat and I can see the index is created with name filebeat-7.5.1-2020.01.08-000001

I would like to have a new index created everyday based on the timestamp from the apache logs.
I have gone through some elastic stack documentation and blogs to achieve this. I was unable to create a new index everyday based on this criteria.

I am stuck with this from two days. We are evaluating elastic stack for our upcoming projects and have not been able to set it up as per the POC requirement.

Can you please point me to a documentation or elastic community post that explains the steps required to set it up.

Hi! Could you give more details about what's not working? Is the problem that it keeps sending to the same (old) index every day, or that it's not recognizing the timestamp in the actual log entries? Could you share your filebeat.yml and some example entries it's failing on?

Thank you @faec for your response. I appreciate your support.

Below is the filebeat.yml from the server which is shipping logs to elasticsearch.

=================================
cat filebeat.yml
###################### Filebeat Configuration Example #########################

This file is an example configuration file highlighting only the most common

options. The filebeat.reference.yml file from the same directory contains all the

supported options with more comments. You can use it as a reference.

You can find the full configuration reference here:

https://www.elastic.co/guide/en/beats/filebeat/index.html

For more available modules and options, please see the filebeat.reference.yml sample

configuration file.

#=========================== 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: false

  Paths that should be crawled and fetched. Glob based paths.

  paths:

  • /var/log/*.log
    #- c:\programdata\elasticsearch\logs*

  Exclude lines. A list of regular expressions to match. It drops the lines that are

  matching any regular expression from the list.

  #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.

  #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 fields can be freely picked

  to add additional information to the crawled log files for filtering

  #fields:

  level: debug

  review: 1

  Multiline options

  Multiline can be used for log messages spanning multiple lines. This is common

  for Java Stack Traces or C-Line Continuation

  The regexp Pattern that has to be matched. The example pattern matches all lines starting with [

  #multiline.pattern: ^[

  Defines if the pattern set under pattern should be negated or not. Default is false.

  #multiline.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

  #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: 1
#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 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:

#============================== 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: "172.31.45.43:5601"

Kibana Space ID

ID of the Kibana Space into which the dashboards should be loaded. By default,

the Default Space will be used.

#space.id:

#============================= 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: ["172.31.45.43:9200"]
index: '%{[agent.version]}-%{+dd.MM.yyyy}'
setup.template:
name: 'srvprod'
pattern: 'srvprod'
enabled: true

Optional protocol and basic auth credentials.

#protocol: "https"
#username: "elastic"
#password: "changeme"

#----------------------------- Logstash output --------------------------------
#output.logstash:

The Logstash hosts

#hosts: ["localhost:5044"]

Optional SSL. By default is off.

List of root certificates for HTTPS server verifications

#ssl.certificate_authorities: ["/etc/pki/root/ca.pem"]

Certificate for SSL client authentication

#ssl.certificate: "/etc/pki/client/cert.pem"

Client Certificate Key

#ssl.key: "/etc/pki/client/cert.key"

#================================ Processors =====================================

Configure processors to enhance or manipulate events generated by the beat.

processors:

• add_host_metadata: ~
• add_cloud_metadata: ~
• add_docker_metadata: ~
• add_kubernetes_metadata: ~

#================================ 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: ["*"]

#============================== X-Pack 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.

#monitoring.enabled: false

Sets the UUID of the Elasticsearch cluster under which monitoring data for this

Filebeat instance will appear in the Stack Monitoring UI. If output.elasticsearch

is enabled, the UUID is derived from the Elasticsearch cluster referenced by output.elasticsearch.

#monitoring.cluster_uuid:

Uncomment to send the metrics to Elasticsearch. Most settings from the

Elasticsearch output are accepted here as well.

Note that the settings should point to your Elasticsearch monitoring cluster.

Any setting that is not set is automatically inherited from the Elasticsearch

output configuration, so if you have the Elasticsearch output configured such

that it is pointing to your Elasticsearch monitoring cluster, you can simply

uncomment the following line.

#monitoring.elasticsearch:

#================================= Migration ==================================

This allows to enable 6.7 migration aliases

#migration.6_to_7.enabled: true
