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.
Fallback-gw is a little script to be called via cron that checks availibility of neighbor routers using ping and activates backup routing on ping failure. It can be used as a stupid replacement for BGP/OSPF in a multihomed environment. It has been tested on FreeBSD and on Linux with iproute2.
SpamBlock counts attempts to establish a connection on port 25/tcp via tcpdump. When a host exceeds the allowed number of attempts per unit of time, it is added to a corresponding ipfw table and email notification is sent. Spamblock currently supports ipfw only, but it can be easily adapted for any firewall and OS. It can also be configured to watch multiple ports to prevent Telnet and SSH attacks in addition to SMTP.
The System Data Recorder has a collection part, or the part that handles recording the data from each system, and a reporting side where it permanently stores and generates simple reports and graphs. For some configurations, it can use only the recording part without the reporting side at all. The data recorder consists of many simple utilities developed in Korn and Perl that extract different telemetry from the Solaris kernel statistic module. Some recorders gather their data from various processes directly using OS or third party utilities. There are 5 recorders that should be installed and deployed in any system, and optional recorders needed only in certain cases: CMT and JVM.
Stats Collector is a set of tools intended to get statistical values from remote nodes. This covers standard server metrics as well as any other numerical value that might be useful, such as the number of running processes or users. It is constructed using a distributed agent-manager model, and uses RRDtool as data backend and to provide visualization capabilities.
This is a package of programs for analyzing Linux memory usage. It is meant to replace the old "memstat", among other things. The program "vmarea" lists all the virtual memory in the system, showing you which processes and mmapped file caches are using it. "slabcache" summarizes Linux kernel working memory. The data comes from /proc.
