Ship MySQL logs

Filebeat
Docker sidecar

MySQL + Filebeat setup

MySQL is an open-source relational database management system. Filebeat is often the easiest way to get logs from your system to Logz.io. Logz.io has a dedicated configuration wizard to make it simple to configure Filebeat. If you already have Filebeat and you want to add new sources, check out our other shipping instructions to copy&paste just the relevant changes from our code examples.

Configuration

Before you begin, you’ll need:

Filebeat installed
Port 5015 open

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 public certificate to your credentials server

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

sudo curl https://raw.githubusercontent.com/logzio/public-certificates/master/AAACertificateServices.crt --create-dirs -o /etc/pki/tls/certs/COMODORSADomainValidationSecureServerCA.crt

Add MySQL as an input in your Filebeat configuration

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

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

Filebeat requires a file extension specified for the log input.

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

  fields:
    logzio_codec: plain

If you’re running Filebeat 7 to 8.1, paste the code block below instead:

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

  fields:
    logzio_codec: plain

    # You can manage your tokens at
    # https://app.logz.io/#/dashboard/settings/manage-tokens/log-shipping
    token: <<LOG-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

    # You can manage your tokens at
    # https://app.logz.io/#/dashboard/settings/manage-tokens/log-shipping
    token: <<LOG-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

    # You can manage your tokens at
    # https://app.logz.io/#/dashboard/settings/manage-tokens/log-shipping
    token: <<LOG-SHIPPING-TOKEN>>
    type: mysql_error

Preconfigured log types

Parameter	Log Type	Default log location
General query log	`mysql`	`/var/log/mysql/mysql.log`
Slow query log	`mysql_slow_query`	`/var/log/mysql/mysql-slow.log`
Error log	`mysql_error`	`/var/log/mysql/error.log`

The log type is used to apply the appropriate Logz.io preconfigured parsing pipeline so that your logs will be automatically parsed.

Set Logz.io as the output

If Logz.io is not an output, add it now. Remove all other outputs.

Replace <<LISTENER-HOST>> with the host for your region. For example, listener.logz.io if your account is hosted on AWS US East, or listener-nl.logz.io if hosted on Azure West Europe. The required port depends whether HTTP or HTTPS is used: HTTP = 8070, HTTPS = 8071.

# ...
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 Open Search Dashboards.

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

Set up a Docker sidecar for MySQL

MySQL is an open-source relational database management system. Docker sidecar is a container that runs on the same Pod as the application container. This integration allows you to send your MySQL logs to your Logz.io account using a Docker sidecar.

Pull the Docker image

Download the logzio/mysql-logs image:

docker pull logzio/mysql-logs

Run the Docker image

For a complete list of options, see the parameters below the code block.👇

docker run -d --name logzio-mysql-logs \
-e LOGZIO_TOKEN="<<LOG-SHIPPING-TOKEN>>" \
-e LOGZIO_LISTENER_HOST="<<LISTENER-HOST>>" \
-v /var/log/logzio:/var/log/logzio \
-v /var/log/mysql:/var/log/mysql \
logzio/mysql-logs:latest

Parameters

Parameter	Description	Required/Default
LOGZIO_TOKEN	Your Logz.io log shipping token directs the data securely to your Logz.io Log Management account. The default token is auto-populated in the examples when you’re logged into the Logz.io app as an Admin. Manage your tokens. Replace `<<LOG-SHIPPING-TOKEN>>` with the token of the account you want to ship to.	Required
LOGZIO_LISTENER	Listener URL. Replace `<<LISTENER-HOST>>` with the host for your region. For example, `listener.logz.io` if your account is hosted on AWS US East, or `listener-nl.logz.io` if hosted on Azure West Europe. The required port depends whether HTTP or HTTPS is used: HTTP = 8070, HTTPS = 8071.	`listener.logz.io`
MYSQL_ERROR_LOG_FILE	The path to MySQL error log.	Optional. `/var/log/mysql/error.log`
MYSQL_SLOW_LOG_FILE	The path to MySQL slow query log.	Optional. `/var/log/mysql/mysql-slow.log`
MYSQL_LOG_FILE	The path to MySQL general log.	Optional. `/var/log/mysql/mysql.log`

Below is an example configuration for running the Docker container:

docker run -d \
  --name logzio-mysql-logs \
  -e LOGZIO_TOKEN="<<LOG-SHIPPING-TOKEN>>" \
  -v /path/to/directory/logzio:/var/log/logzio \
  -v /path/to/directory/mysql:/var/log/mysql \
  --restart=always \
  logzio/mysql-logs:latest

Check Logz.io for your logs
