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.
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.
Monitoring::Spooler is a handy queue manager for queueing and delivery of monitoring notifications. It is able to handle several groups of on-call personnel and provides an extensible plugin mechanism to connect it to virtually any remote service which provides some kind of API. It is designed to work nicely with App::Standby.
