New page

Status server

Requires graphviz

This consists of several C programs as CGI's and uses LMDB to store data nodes post to the server.

* index.cgi - generates the code for the index page and textual output
* uhandler.cgi - receives the http get requests of data from the nodes and writes it to the LMDB
* nodeinfo.cgi - gives the per node report text page
* getconn.cgi - not really needed for the user interface. ?$NODE returns text with the total number of connected nodes and the state of each connected node separated by pipes
* statsdb.cgi - not needed for the interface. If the compiled in IP is matched, it will return a dump of the database.
* jsondata.cgi - not needed for the interface, no sure what it does.
* getstatus.cgi - generates the per node PNG image using getstatus and neato

These next are not publicly accessible files and are called by the system

* mkstatslmdb
* mkstatus
* getstatus
