Debian, Ansible & zabbix Part I

Merging Ansible with Zabbix under Debian 10.

I recenty rediscovered Ansible and wondered if I could use Ansible to create trigger actions and scripts to maintain my home lab. It turns out you can with some adjustments to the Zabbix server.

As an example I use Zabbix to monitor the available updates on my Debian vm’s. When updates are detected, I fire up my dedicated Ansible vm and run my update playbook, which works fine. The only downside is that I must boot the dedicated Ansible server and run the playbooks against the “to be updated” hosts. This is a bit time consumming and wondered if I could update the vm using Zabbix.

What if I could run the playbooks directly from within the Zabbix instance? Mmmm!

I went on the net looking for examples of such howto’s, but wasn’t able to find any. Guess I had to make my own then.

Zabbix within Synology Docker

As there were a few nice “how to’s” found on the internet about setting up Zabbix running on Docker containers within the Synology nas, time will eventually catch up those articles, as it will catch up this article eventually.

This article is just FYI and is based on a mixture of “the monitoring artist” and “Struiners Unie“. I don’t get into the details as my fellow Zabbix enthusiasts did but present you a working system.

First to know is that we are using three separate containers. One for the DB storage, one for the actual DB and one for Zabbix.

Step 1:

Create a new directory within the shared Docker directory (which is created when installing Docker). I called it Zabbix:)

Docker Share
Docker Share

Step 2:

Create a Docker container with the following command:

docker run -d -v /var/lib/mysql --name zabbix-db-storage busybox:latest

This will create a container which hasn’t a lot of use, but is needed so we can link to actual  storage. Create a volume within this container and point it to the newly create directory:

linked storage
linked storage

As far as I can see, we just need to start up the container for one time, afterwards we can ignore the container.

Step 3:

Now for a big step, create the Zabbix  database:

docker run -d --volumes-from zabbix-db-storage --name zabbix-db -p 63306:3306 --env="MARIADB_USER=zabbix" --env="MARIADB_PASS=STRONGPASS" --env="DB_innodb_buffer_pool_size=768M" monitoringartist/zabbix-db-mariadb:latest

,…and start the container.

Step 4:

Install the Zabbix container with the following command:

docker run -d --name zabbix -p 8080:80 -p 10051:10051 -v /etc/localtime:/etc/localtime:ro --link zabbix-db:zabbix.db --env="PHP_date_timezone=Europe/Amsterdam" --env="ZS_DBHost=zabbix.db" --env="ZS_DBUser=zabbix" --env="ZS_DBPassword=STRONGPASS" monitoringartist/zabbix-xxl:latest

Wait a few (+/- 10 minutes) minutes and the zabbix will be available to you, using Admin as user and zabbix as password.

 

Enjoy

PS.

I have noticed that browsing my Zabbix webpage, there was a google tracker active which can be disabled within the container environment parameter : XXL_analytics = false. It’s on by default. Just that you know.

Synology DS1815+ 16GB ram upgrade

A year ago I decided that my current Synology DS1815+ was ready to take on some extra ram. Factory delivered, the nas only has 2GB of ram, which is not much. Especially when you want to use the SSD cache feature, the minimal ram needed was 6GB. So I upgraded it;)

Now that I have discovered Docker, which can be memory intensive at times (using Zabbix containers) it was time to further upgrade the ram. And although Synology stated that only the maximum of 6GB ram is supported I wandered around the internetz and found out it is possible to upgrade the ram to 16GB.

Zabbix Trigger Web Dashboard

Yet Another Zabbix Dashboard 🙂

Build with Php, it gets the active triggers from certain groups. Tested in 2.2.x and 3.0.x. Php Api is included.
