NetWhistler

NetWhistler is an easy to use open-source Network mapping and SNMP monitoring software that offers integrated fault and performance management functionality.
This desktop program auto-detects networks and presents them on graphical maps, which reflect up-to-the-minute device and host status. It includes powerful diagnostic tools including ping, trace, telnet, main network services monitoring, portscan, vncviewer, email alerts, network discovery, SNMP tools (MIB browser, Trap Console for incoming SNMP traps from any SNMP-enabled device in the network and an MRTG Console (JRobin MRTG) for traffic graphs), port mapper in SNMP status, syslog server, web console and etc.

NetWhistler can automatically scan a network in search of non-SNMP and SNMP-enabled devices that you want to manage in your network. Scanning parameters (network address, network mask, SNMP community) are fully configurable.
Once the discovery operation has been completed, the program displays a map of all devices along with basic information about them such as address, DNS name, MAC address and description. You can find or delete a node on the map, or change node properties. The map can be stored in a local xml file.

From 2.10 version you can use Python scripts for ping, mac-address detecting and snmp results processing.
