Zabbix Docker (How it Works for Developers)

As containerization is at the core of modern application deployment, monitoring Docker environments is vital for efficiency, performance, and dependability. Docker monitoring tools collect essential metrics such as CPU and memory consumption, network activity, and disk I/O. These tools track the performance and health of containers, providing insights into the system. They must be used to solve problems quickly, optimize resources, and ensure smooth operations in a containerized environment.

Zabbix is a leading open-source monitoring tool with robust Docker environment monitoring capabilities. It is well-suited for companies with extensive containerized infrastructures that require oversight, offering real-time monitoring, visualization, and alerting facilities.

What is Zabbix Docker?

Zabbix Docker is one of the most flexible and powerful solutions for fully monitoring Docker environments. Being an open-source extension of the base platform, the Zabbix version for Docker allows users to monitor the health, performance, and resource utilization of any container, host, and all related infrastructure. The Zabbix agent comes pre-configured with templates tailored for Docker, making it easy to monitor important metrics like CPU, memory, disk I/O, network activity, container status, uptime, and restart counts.

Zabbix Docker provides organizations with the ability to proactively manage their containerized workloads, quickly identify and resolve issues, and optimize resource usage by collecting real-time data. It offers customizable dashboards and alerting capabilities, making it perfectly scalable and integrative with other systems. This makes Zabbix Docker the ideal choice for teams working on containerized applications in small to enterprise environments. Zabbix Docker assures businesses of reliable and efficient performance in Dockerized infrastructure while maintaining a unified view of monitoring in different systems.

Install Zabbix Docker

Prerequisites

• Docker and Docker Compose: Ensure Docker and Docker Compose are installed on your system. If not, install Docker and Docker Compose.
• Sufficient Resources: Assign enough CPU, memory, and storage to Zabbix server containers according to your monitoring scale.
• Network Configuration: Ports for all Zabbix components such as 10051, 80, and 443 should be free from conflicts with other services.

Download Zabbix Docker Files

Clone the Zabbix Docker repository from GitHub:

git clone https://github.com/zabbix/zabbix-docker.git
cd zabbix-docker

git clone https://github.com/zabbix/zabbix-docker.git
cd zabbix-docker

Edit the .env file (if available) or directly modify the docker-compose.yml file to customize your setup.

Start the Zabbix server containers and install additional components with the following command:

docker-compose -f docker-compose_v3_alpine_pgsql_latest.yaml up -d

docker-compose -f docker-compose_v3_alpine_pgsql_latest.yaml up -d

This command pulls the required Zabbix images and starts the containers for the various Zabbix components: server, frontend, database, and optionally, Zabbix agents to enhance the Zabbix server.

You can log into the Zabbix web interface using the default credentials once the installation is completed.

What is IronSecureDoc?

IronSecureDoc is a document management and security tool providing digital signing, complex PDF manipulation, and advanced encryption. It simplifies PDF processing while maintaining document confidentiality and integrity for businesses and developers with easy access. Its features allow developers to produce, upload, modify, and secure PDF files and documents programmatically, functioning as a robust PDF API.

Besides these, IronPDF is a PDF API that allows the creation of PDFs with various input data, including text, images, and metadata. It includes facilities for merging different PDFs, composing files, splitting documents, and even adding comments, highlights, or watermarks.

It provides password protection, AES encryption, and certificate-based access controls, safeguarding sensitive information. Additionally, it offers digital signing for document authentication, crucial in financial, medical, and legal industries. The audit trail functionality allows tracking of all activities performed on documents for better compliance and accountability.

Install and Run IronSecureDoc

Pull the Docker image of IronSecureDoc from the repository using the command below:

docker pull ironsoftwareofficial/ironsecuredoc

docker pull ironsoftwareofficial/ironsecuredoc

Start the IronSecureDoc operating container with the following command:

docker container run --rm -p 8080:8080 -e IronSecureDoc_LicenseKey=<IRONSECUREDOC_LICENSE_KEY> -e ENVIRONMENT=Development -e HTTP_PORTS=8080 ironsoftwareofficial/ironsecuredoc:latest

docker container run --rm -p 8080:8080 -e IronSecureDoc_LicenseKey=<IRONSECUREDOC_LICENSE_KEY> -e ENVIRONMENT=Development -e HTTP_PORTS=8080 ironsoftwareofficial/ironsecuredoc:latest

This command launches a container instance of IronSecureDoc.

Create API Monitoring

Create a New Host

Log in to the Zabbix Web UI.

Navigate to Data Collection > Hosts and click Create Host.

Add IronSecureDoc as a host, specifying its IP or DNS and group.

Add a New HTTP Item

• Go to the created host and click on Items > Create Item.
• Set the Type to HTTP Agent.
• Enter the URL of the IronSecureDoc API endpoint, such as /document-services/ping or /document-services/check-license.

Log and Agent Monitoring on Zabbix for IronSecureDoc

Log monitoring and agent-based monitoring with Zabbix provide full insight into the performance and health of the IronSecureDoc application. Log monitoring requires the installation of the Zabbix agent on the server hosting IronSecureDoc and setting up a monitor to track relevant log files for specific patterns like errors, warnings, or document activity. Define Zabbix items of type Log to filter relevant events and set up triggers to alert on critical log entries so that issues are addressed promptly.

For agent-based monitoring, use the Zabbix agent to collect system-level metrics such as CPU, memory, and disk usage, essential for understanding IronSecureDoc's resource utilization. You can also improve monitoring by writing custom UserParameter scripts to monitor IronSecureDoc-specific metrics, like active sessions or the number of signed documents. This ensures real-time monitoring and proactive management of IronSecureDoc within your infrastructure.

Sample IronSecureDoc Request

IronSecureDoc's REST API offers a contemporary, web-based interface for safely interacting with functionalities for managing documents, including advanced PDF processing, via RESTful principles. It offers a simple, regulated approach to including different functionalities from IronSecureDoc into custom applications, no matter which stack technologies are employed.

To post to the IronSecureDoc API and request a permission password for encrypting a document with a user password, use the following command:

curl -X 'POST' \
  'http://c0kwcw4k4wkw8gw4ww8wkg8s.41.243.46.67.sslip.io/v1/document-services/pdfs/encrypt?user_password=demo' \
  -H 'accept: */*' \
  -H 'Content-Type: multipart/form-data' \
  -F 'pdf_file=@test.pdf;type=application/pdf'

curl -X 'POST' \
  'http://c0kwcw4k4wkw8gw4ww8wkg8s.41.243.46.67.sslip.io/v1/document-services/pdfs/encrypt?user_password=demo' \
  -H 'accept: */*' \
  -H 'Content-Type: multipart/form-data' \
  -F 'pdf_file=@test.pdf;type=application/pdf'

The document output file will be automatically sent and downloaded, and it will also be safely saved.
