! Navigation
[Eksplane|http://spacepirates.com/ro/experiments/eksplane/], a simplistic Django prototype that was excluding reports and recording and focusing on real time navigation and links between different aspects of a live Unix sysem (process, files, sockets, ports etc.). The idea was to render the output of Unix commands as HTML enriched with hyperlinks specific to the type of the information in that output (e.g. a PID in the output is clickable so you get the choice of pstack, lsof, arguments etc.).

!!! Background information
!! Parsing text
Parsing text is key as most important commands output text and most log files are text based.
Some tools output HTML and parsing HTML (probably bad HTML) is important too. [TagSoup|http://home.ccil.org/~cowan/XML/tagsoup/] and [Jericho|http://jericho.htmlparser.net/docs/index.html] may be useful.
!! Unix commands
There are many unix commands and other tools that are good sources of information for this project:
* __ps__: list processes, arguments, resource usage etc.
* __pstack__, __gstack__, __procstack__, __dbx/gdb + where__ : show the call stack(s) of a given process
* __pfiles__, __procfiles__, __lsof__ : show files used by one or multiples processes
* __pmap__, __procmap__, __jmap__: memory usage of a given process
* __netstat__, __ifconfig__
* __df__: show disk utilisation of partitions etc.
* __iostat__, __iotop__ etc
* __sp_sysmon__: show Sybase activity summary
* __uname__
* __prtdiag__,
* __vmstat__, __free__: system memory usage
* __lpr__
* __dmesg__, __cat /var/log/messages__, errpt -a : display operating system messages
!! Log files
* __core__,__hserr*.log__, javacore*: files generated by programs that have errors
* LOG4J files
* strace, truss output
!! Database commands
! Sybase
* sp_sysmon
* sp_help
! Oracle
* AWR report
