Network and server monitoring¶
Graph monitoring with cacti¶Cacti is a tool to collect values from machines and network equipments and to represent them in graphs.
Values are collected using SNMPv2. Most of the equipments in the B25 lab use the read-only community ''b25'' or ''cacti'' (example L.54)
TODO: Make all SNMP configurations consistent
IP monitoring (net-scan)¶
A nmap instance regularly scans the public IPv4 range used in the lab to detect new pingable public IPv4 and/or new open TCP port.
Rule of thumb: Every pingable IPv4 address must be registered in the reverse DNS file
TODO: Integrate ndpmon tool for IPv6 discovery and perform nmap scan on discovered IP.
Nagios is a tool which monitor service reachability. Notifications can be sent by mail when detecting a problem. Centreon is a web portal to configure Naagios.
These tools have been deployed as part of the FAN (Fully Automated Nagios) Linux distribution. This distribution is currently used as a virtual machine running on the MacMini Server.
