BGPHist is a tool that receives MP-BGP updates, decodes them, and writes them to a database for logging and monitoring purposes. It supports not only Internet routes, but also IPv4 VPN, IPV6 VPN, and L2VPN. It sounds text output, MySQL databases, and Oracle databases. For the MySQL backend, there is also a simple PHP frontend. It could be used to monitor and log an ISP's customer activity for Internet and VPNs, as a passive BGP looking glass, or as a backend for some external monitoring and accounting system.
Orabbix is a plugin designed to work with Zabbix Enterprise Monitor to provide multi-tiered monitoring and performance and availability reporting and measurement for Oracle Databases, along with server performance metrics. It provides an effective mechanism to acquire data from numerous Oracle 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.
