MySQL + Filebeat setup

Configuration tl;dr

Item	Description
Files	Sample configuration Encryption certificate
Listener	Port 5015. For help finding your region’s listener host, see Account region.
Default log locations	General query log: /var/log/mysql/mysql.log Slow query log: /var/log/mysql/mysql-slow.log Error log: /var/log/mysql/error.log

Guided configuration

Before you begin, you’ll need: Filebeat 7 or Filebeat 6, MySQL

Configure MySQL to write general query logs

In the MySQL configuration file (/etc/mysql/my.cnf), paste these lines:

general_log_file = /var/log/mysql/mysql.log
general_log= 1
log_slow_queries = /var/log/mysql/mysql-slow.log
long_query_time = 1
log-queries-not-using-indexes = 1

Restart MySQL.

sudo /etc/init.d/mysql restart

Download the Logz.io certificate

For HTTPS shipping, download the Logz.io public certificate to your certificate authority folder.

sudo wget https://raw.githubusercontent.com/logzio/public-certificates/master/COMODORSADomainValidationSecureServerCA.crt -P /etc/pki/tls/certs/

Add MySQL as an input

In the Filebeat configuration file (/etc/filebeat/filebeat.yml), add MySQL to the filebeat.inputs section.

Replace <<SHIPPING-TOKEN>> with the token of the account you want to ship to.

# ...
filebeat.inputs:
- type: log
  paths:
    - /var/log/mysql/mysql.log

  fields:
    logzio_codec: plain

    # Your Logz.io account token. You can find your token at
    #  https://app.logz.io/#/dashboard/settings/manage-accounts
    token: <<SHIPPING-TOKEN>>
    type: mysql
  fields_under_root: true
  encoding: utf-8
  ignore_older: 3h

- type: log
  paths:
    - /var/log/mysql/mysql-slow.log

  fields:
    logzio_codec: plain

    # Your Logz.io account token. You can find your token at
    #  https://app.logz.io/#/dashboard/settings/manage-accounts
    token: <<SHIPPING-TOKEN>>
    type: mysql_slow_query
  fields_under_root: true
  encoding: utf-8
  ignore_older: 3h
  multiline:
    pattern: '^# Time:'
    negate: true
    match: after

- type: log
  paths:
    - /var/log/mysql/error.log

  fields:
    logzio_codec: plain

    # Your Logz.io account token. You can find your token at
    #  https://app.logz.io/#/dashboard/settings/manage-accounts
    token: <<SHIPPING-TOKEN>>
    type: mysql_error
  fields_under_root: true
  encoding: utf-8
  ignore_older: 3h

If you’re running Filebeat 7, paste this code block. Otherwise, you can leave it out.

# ... For Filebeat 7 only ...
filebeat.registry.path: /var/lib/filebeat
processors:
- rename:
    fields:
    - from: "agent"
      to: "filebeat_agent"
    ignore_missing: true
- rename:
    fields:
    - from: "log.file.path"
      to: "source"
    ignore_missing: true

If you’re running Filebeat 6, paste this code block.

# ... For Filebeat 6 only ...
registry_file: /var/lib/filebeat/registry

Add Logz.io as an output

If Logz.io is not an output, add it now.

Replace <<LISTENER-HOST>> with your region’s listener host (for example, listener.logz.io). For more information on finding your account’s region, see Account region.

# ...
output.logstash:
  hosts: ["<<LISTENER-HOST>>:5015"]
  ssl:
    certificate_authorities: ['/etc/pki/tls/certs/COMODORSADomainValidationSecureServerCA.crt']

Start Filebeat

Start or restart Filebeat for the changes to take effect.

Check Logz.io for your logs

Give your logs some time to get from your system to ours, and then open Kibana.

If you still don’t see your logs, see log shipping troubleshooting.
