Funcios is a set of Nagios plugins which check Linux health and status using ​Func

Func is the Fedora Unified Network Controller and allows you to do cool stuff like:

• Control lots of machines from one location
• Updating your machines
• Poll hardware information
• Poll process, cpu, disk information

Some advantages

• Offloading load from running checks off the Nagios machine and onto the Func Overlord
• Func install on servers is really easy
• Secure, uses SSL client/server certificates
• No upload/install of check plugins on servers uses func native functionality
• If check plugins are required, they can be uploaded and run through func infrastructure

Implementation overview for load monitoring using check once, return many method

Flow:

1. Nagios runs "Funcios Load Runner" check on the Func overlord
2. Funcios Load Runner check runs, with standard Nagios $USER1$/funcios-load --multiple -H *
3. funcios-load fetched load for every Func minion configured and specified via -H
4. funcios-load sends passive data for each host, <hostname>, <check name eg Load Average>; and the return code, status + performance data
