monitoringartist/zabbix-2.4 repository overview

⁠Zabbix XXL

Zabbix XXL⁠ is a standard Zabbix prepared for Docker world. You must install Zabbix package (rpm, deb, ...) in the old world. Similarly you need to pull Zabbix Docker image in the Docker world. This Docker image contains standard Zabbix + additional XXL (community) extensions. Routine tasks such as import of Zabbix DB are automated, so it's prepared for easy deployment.

Overview of Monitoring Artist (dockerized) monitoring ecosystem:

• Zabbix XXL⁠ - standard Zabbix 3.0 server/proxy/UI/snmpd/java gateway with additional XXL extensions
• Zabbix agent XXL⁠ - Zabbix 3.0 agent with Docker (Mesos/Chronos/Marathon) monitoring⁠ and systemd monitoring⁠
• Zabbix templates⁠ - tiny (5MB) image for easy template deployment of selected Zabbix monitoring templates
• Zabbix extension - all templates⁠ - storage image for Zabbix XXL with 200+ community templates⁠
• Kubernetized Zabbix⁠ - containerized Zabbix cluster based on Kubernetes
• Grafana XXL⁠ - dockerized Grafana with all community plugins
• Grafana dashboards⁠ - Grafana dashboard collection for AWS⁠ and Zabbix⁠
• Monitoring Analytics⁠ - R statistical computing and graphics for monitoring from data scientists
• Docker killer⁠ - Docker image for Docker stress and Docker orchestration testing

⁠zabbix-2.4

Zabbix 2.4 is not supported - please use 3.0 version - http://www.zabbix.com/life_cycle_and_release_policy.php⁠

Compiled Zabbix with almost all features (MySQL support, Java, SNMP, Curl, Ipmi, fping) and Zabbix web UI based on CentOS 7, Supervisor, Nginx, PHP. Image requires external MySQL database (you can run MySQL also as Docker container).

⁠Standard Dockerized Zabbix deployment

# create /var/lib/mysql as persistent volume storage
docker run -d -v /var/lib/mysql --name zabbix-db-storage busybox:latest

# start DB for Zabbix - default 1GB innodb_buffer_pool_size is used
docker run \
    -d \
    --name zabbix-db \
    -v /backups:/backups \
    -v /etc/localtime:/etc/localtime:ro \
    --volumes-from zabbix-db-storage \
    --env="MARIADB_USER=zabbix" \
    --env="MARIADB_PASS=my_password" \
    monitoringartist/zabbix-db-mariadb

# start Zabbix linked to started DB
docker run \
    -d \
    --name zabbix \
    -p 80:80 \
    -p 10051:10051 \
    -v /etc/localtime:/etc/localtime:ro \
    --link zabbix-db:zabbix.db \
    --env="ZS_DBHost=zabbix.db" \
    --env="ZS_DBUser=zabbix" \
    --env="ZS_DBPassword=my_password" \
    monitoringartist/zabbix-2.4
# wait ~60 seconds for Zabbix initialization
# Zabbix web UI will be available on the port 80, Zabbix server on the port 10051

Examples of admin tasks:

# Backup of Zabbix configuration data only
docker exec \
    -ti zabbix-db \
    /zabbix-backup/zabbix-mariadb-dump -u zabbix -p my_password -o /backups

# Full DB backup of Zabbix
docker exec \
    -ti zabbix-db \
    bash -c "\
    mysqldump -u zabbix -pmy_password zabbix | \
    bzip2 -cq9 > /backups/zabbix_db_dump_$(date +%Y-%m-%d-%H.%M.%S).sql.bz2"

⁠Up and Running with Docker Compose

docker-compose up -d

⁠Zabbix database as Docker container

To be able to connect to database we would need one to be running first. Easiest way to do that is to use another docker image. For this purpose you can use monitoringartist/zabbix-db-mariadb⁠ image as database.

For more information about monitoringartist/zabbix-db-mariadb see README of zabbix-db-mariadb⁠.

Example:

docker run \
	-d \
	--name zabbix-db \
	-p 3306:3306 \
	-v /etc/localtime:/etc/localtime:ro \
	--env="MARIADB_USER=zabbix" \
	--env="MARIADB_PASS=my_password" \
	monitoringartist/zabbix-db-mariadb

Remember to use the same credentials when deploying zabbix image.

⁠Environmental variables

You can use environmental variables to config Zabbix server and Zabbix web UI (PHP). Available variables:

⁠Configuration from volume

Full config files can be also used. Environment configs will be overriden by values from config files in this case. You need only to add /etc/custom-config/ volume:

-v /host/custom-config/:/etc/custom-config/

Available files:

Zabbix role environment variables:

All Zabbix components are enabled by default except SNMP traps proccessing. However users want to run dedicated Zabbix component per container. Typical use case is Zabbix web UI. Thanks to role environment variables are users able to execute many web UI containers, which helps to scale Zabbix as a service.

⁠Zabbix deployment

Now when we have Zabbix database running we can deploy Zabbix image with appropriate environmental variables set.

Example:

docker run \
	-d \
	--name zabbix \
	-p 80:80 \
	-p 10051:10051 \
	-v /etc/localtime:/etc/localtime:ro \
	--link zabbix-db:zabbix.db \
	--env="ZS_DBHost=zabbix.db" \
	--env="ZS_DBUser=zabbix" \
	--env="ZS_DBPassword=my_password" \
	monitoringartist/zabbix-2.4

⁠Access to Zabbix web interface

To log in into Zabbix web interface for the first time use credentials Admin:zabbix.

Access web interface under http://docker_host_ip⁠

⁠Docker troubleshooting

Use docker command to see if all required containers are up and running:

$ docker ps

Check logs of Zabbix container:

$ docker logs zabbix

Sometimes you might just want to review how things are deployed inside a running container, you can do this by executing a bash shell through docker's exec command:

docker exec -ti zabbix /bin/bash

History of an image and size of layers:

docker history --no-trunc=true monitoringartist/zabbix-2.4 | tr -s ' ' | tail -n+2 | awk -F " ago " '{print $2}'

Run specific Zabbix version, e.g. 2.4.4 - just specify 2.4.4 tag for image:

	docker run \
		-d \
		--name zabbix \
		-p 80:80 \
		-p 10051:10051 \
		-v /etc/localtime:/etc/localtime:ro \
		--link zabbix-db:zabbix.db \
		--env="ZS_DBHost=zabbix.db" \
		--env="ZS_DBUser=zabbix" \
		--env="ZS_DBPassword=my_password" \
		monitoringartist/zabbix-2.4:2.4.4
