(plugin). It is something like the Ping plugin.
Plugin generates events if a device on local network changes its status (away, present).
Devices can be organized into groups. The plugin then generates events also based on the status of these groups (empty, incomplete, complete).
Here I have to say that I've never used the Ping plugin, but I read the relevant topic.
I hope you will play with the new plugin and it will find its users.
Plugin is based on Nmap. Actually, it's Nmap frontend.
It follows that install Nmap is a prerequisite for the functioning of this plugin.
Nmap scans the network and the plugin handles the scanning results. Scanning is done periodically every 30 seconds.
As a unique identifier for each device on the network does not use IP address, but MAC address.
It is very convenient, but it may mean a little complication when setting up the plugin.
Reliability of scanning is not 100%. The fault lies not on the side of Nmap, but on the part of some devices
(especially smartphones), which use various saving modes. Hence, the device is considered to be disconnected at the moment
when it is not found during several successive scans. This number can be adjusted using the Security factor parameter.
This means that at the default setting of 8 is a disconnection detected after 8 * 30 seconds, i.e. after four minutes.
WARNING!
Scanning is performed on OSI layer two, so devices that are separated using a router operating at layer 3 are not visible!
Pako
