Zabbix Trapper

Zabbix-Trapper is a component of the Zabbix monitoring system that allows agents to send data to the Zabbix server. It is used for passive monitoring, where the server receives data from agents without actively polling them. This service is essential for efficient and scalable monitoring of large infrastructures.

What is Zabbix Trapper

Zabbix-Trapper is a crucial part of the Zabbix monitoring system, which is widely used for monitoring IT infrastructure, services, applications, and resources. The Zabbix-Trapper service listens on port 10051 and allows Zabbix agents to send collected data to the Zabbix server. This passive monitoring approach helps in reducing the load on the network and the monitored devices, as the server does not need to actively poll each agent.

The Zabbix monitoring system was developed by Alexei Vladishev and has grown to become one of the most popular open-source monitoring solutions. It provides a wide range of features, including real-time monitoring, alerting, and reporting. Zabbix-Trapper plays a vital role in ensuring that the system can handle large volumes of data efficiently, making it suitable for monitoring extensive and complex IT environments.

Using Zabbix-Trapper, organizations can achieve a high level of automation in their monitoring processes. The service supports various data collection methods, including agent-based and agentless monitoring, and can integrate with other systems and applications. This flexibility makes Zabbix a preferred choice for many enterprises looking to maintain the health and performance of their IT infrastructure.

Zabbix Trapper runs on TCP and UDP port 10051 and is official IANA port.

Security risk

If port 10051 is open and the Zabbix-Trapper service is running, it could be a potential target for unauthorized access or data injection attacks. Ensuring proper authentication and encryption is crucial to mitigate these risks. Additionally, monitoring and logging access to this port can help in detecting and responding to any suspicious activities.

In our UFW tutorial you can follow instructions how you can configure UFW to close port 10051. Use StackChanges to monitor if the Zabbix Trapper port is closed and stays closed. StackChanges will send an alert if port 10051 is open again.
