NSCAweb is a Nagios core (tm) based monitoring solution addon which allows you to easily submit (passive) host and service checks over http(s) to the Nagios external command file.
It aims to be a better,more feature rich alternative than the classic NSCA daemon.
NSCAweb has following features:
http(s) as transport makes it more friendly in a firewalled environment.
SSL encryption when desired.
Supports multiline plugin & performance output.
Submit data to many types of destinations: named pipes (nagios.cmd), NSCAweb, NRDP or a file.
Loadbalance and failover between multiple urls per destination.
Duplicate and forward passive check results to an "unlimited" amount of destinations.
Submit messages to 1 destination or all destinations depending on the url messages are to.
Simultaneous local and remote delivery.
Each destination has an independent, dedicated thread and queue.
Buffering of unavailable destinations and resubmitting when destination comes available to prevent data loss.
Builtin, multiuser authentication.
Trivial to submit check results using http post.
Submit check results in bulk or one by one.
Use curl as a client from the command line.
Can be compiled easily to a binary using cxfreeze.
It's fast.
NSCAweb is written in Python and has its own built in web server (Cherrypy) and queue manager (Pyhton queue).
