Munin::Node::SNMPConfig - Subroutines providing munin-node-configure's SNMP
my $snmp = Munin::Node::SNMPConfig->new(
community => 'secret',
version => 1,
Constructor. Valid arguments are:
The list of hosts to scan, in a format understood by
Port to connect to. Default is 161.
The SNMP version to use. Default is '2c'.
The community string to use for SNMP version 1 or 2c. Default is 'public'.
The Transport Domain to use for exchanging SNMP messages. The default
is UDP/IPv4. Possible values: 'udp', 'udp4', 'udp/ipv4'; 'udp6',
'udp/ipv6'; 'tcp', 'tcp4', 'tcp/ipv4'; 'tcp6', 'tcp/ipv6'.
The SNMPv3 username to use.
SNMPv3 Authentication password. Optional when encryption is also enabled, in
which case defaults to the privacy password ("privpassword"). The
password is sent encrypted (one way hash) over the network.
SNMPv3 Authentication protocol. One of 'md5' or 'sha' (HMAC-MD5-96, RFC1321
and SHA-1/HMAC-SHA-96, NIST FIPS PIB 180, RFC2264). The default is 'md5'.
SNMPv3 Privacy password to enable encryption. An empty ('') password is
considered as no password and will not enable encryption.
Privacy requires a v3privprotocol as well as a v3authprotocol and a
v3authpassword, but all of these are defaulted (to 'des', 'md5', and the
v3privpassword value, respectively) and may therefore be left unspecified.
If the v3privpassword is set this setting controls what kind of encryption is
used to achieve privacy in the session. Only the very weak 'des' encryption
method is supported officially. The default is 'des'.
The implementing perl module (Net::SNMP) also supports '3des' (CBC-3DES-EDE
aka Triple-DES, NIST FIPS 46-3) as specified in IETF
draft-reeder-snmpv3-usm-3desede. Whether or not this works with any particular
device, we do not know.
Connects to each host in turn, and checks which plugins it supports, based on
the OIDs they reported during snmpconf. If all the requirements are
fulfilled, it will added to the corresponding plugin's suggestions list.
$plugins should be a Munin::Node::Configure::PluginList object.
