Full Description


Docker hub repository

This container monitors your MySQL cluster.
It ships its logs and MySQL logs automatically to via SSL so everything is encrypted.
The container also provides a Nagios plugin script that uses local caches from the regular monitoring routine, so you won't overload your MySQL with unnecessary queries.
It's can be integrated with Amazon RDS.

The containers monitors these values:

  • Connection_Failed_Attempts - Count the The total number of failed attempts to connect to MySQL
  • Detected_Deadlock - Value of 1 will note the a deadlock has been detected
  • Percentage_Of_Full_Table_Scans - The percentage of full table running queries
  • Users_Missing_Password - Count the number of users without a password
  • Root_User - Value of 1 indicat the a 'root' user exist
  • Open_Users - Count the number the number of users that can be connected from anywere
  • Percentage_Of_Allowed_Connections - The percentage of currently used connections
  • Slave_IO_Running - Whether the I/O thread for reading the masters binary log is running. Normally, you want this to be Yes unless you have not yet started replication or have explicitly stopped it with STOP SLAVE.
  • Slave_SQL_Running - Whether the SQL thread for executing events in the relay log is running. As with the I/O thread, this should normally be Yes
  • Seconds_Behind_Master - The lag from the master
  • Uptime - The number of seconds the MySQL server has been running.
  • Current_Active_Clients - The number of active threads (clients).
  • Queries_Since_Startup - The number of questions (queries) from clients since the server was started.
  • Slow_queries - The number of queries that have taken more than long_query_time seconds.
  • Opens_Tables - The number of tables the server has opened.
  • Flush_Tables - The number of flush, refresh, and reload commands the server has executed.
  • Current_Open_Tables - Total number of open tables in the database.
  • Queries_per_second_avg - The number of tables that currently are open

Required MySql permissions

mysql> SHOW GRANTS FOR 'monitor_user'@'monitor_host';
| Grants for monitor_user@monitor_host                                                                                                      |

Usage (docker run)

docker run -d --name logzio-mysql-monitor -e LOGZIO_TOKEN=VALUE -e MYSQL_HOST=VALUE -e MYSQL_USER=VALUE \
           -v path_to_directory:/var/log/logzio \


docker run -d \
  --name logzio-mysql-monitor \
  -e MYSQL_HOST="master.sqlserver.hostname slave1.sqlserver.hostname slave2.sqlserver.hostname" \
  -e MYSQL_USER="myuser" \
  -e MYSQL_PASS="secret" \
  -e MYSQL_REPLICAS="slave1.sqlserver.hostname slave2.sqlserver.hostname" \
  -v /path/to/directory:/var/log/logzio \
  --restart=always \


LOGZIO_TOKEN - Your App token, where you can find under "settings" in the web app.
MYSQL_HOST - List of your mysql hosts to monitor.
MYSQL_USER - Your mysql user


MYSQL_PASS - Your mysql user. Default: None
MYSQL_REPLICAS - List of your mysql replicas to monitor. Default: None
INTERVAL_SECONDS - Number of seconds to sleep between each call to monitor. Default: 60
LOGZIO_LISTENER - Logzio listener host name. Default:

Usage (nagios monitor)

Nagios monitoring implements Nagios native plugin interface.
Which means by exit codes:

exit 0 # Everything is awesome
exit 1 # Warning!
exit 2 # Critical!!
exit 3 # Unknown

It will also print a message that both humans and Nagios loves. Expect something like:

CRITICAL: Users_Missing_Password is: 1, which is higher or equal to the critical threshold: 0 | Users_Missing_Password: 1

The data before the pipeline is for your notifications, and the data after the pipeline is for you to use in nagios performance data.

Available monitoring components and usage



docker exec CONTAINER_NAME /root/ "" Seconds_Behind_Master -c 2 -w 1

All available are listed above. And you can also list them by running:
