snmp4zabbix provides a simple SNMP interface to the Zabbix monitoring solution. This lets Zabbix monitor itself using the Simple Network Management Protocol. This is an alternate solution to the Zabbix API for integration, to some extent, with any third party software capable of understanding SNMP.
Postbix is a plugin designed to work with Zabbix Enterprise Monitor to provide multi-tiered monitoring and performance and availability reporting and measurement for PostgreSQL databases, along with server performance metrics. It provides an effective mechanism to acquire data from numerous PostgreSQL instances, and in turn provides this information for monitoring and performance metrics to your Zabbix server. You can then utilise the reporting capabilities of Zabbix for all data collected, and provide analysis such as graphs and service-level agreement metrics for stakeholders. The current distribution contains a set of pre-defined templates that incorporate alerting and graphing capabilities from initial deployment. However, these can be fine tuned to suit your needs and data/monitoring requirements.
Zabbix/J is a framework for integrating Zabbix monitoring into Java applications. Zabbix is an "enterprise-class Open Source distributed monitoring solution" which provides telemetry and triggers across entire infrastructures. Zabbix/J makes it simple to expose metrics from your Java applications, giving them visibility as first class citizens in a Zabbix configuration.
