Munin::Node::SNMPConfiUser Contributed Perl DocumentMunin::Node::SNMPConfig(3)NAMEMunin::Node::SNMPConfig - Subroutines providing munin-node-configure's
SNMP scanning capabilities.
SYNOPSIS
my $snmp = Munin::Node::SNMPConfig->new(
community => 'secret',
version => 1,
);
$snmp->probe_hosts(\%plugins);
SUBROUTINES
new(%arguments)
Constructor. Valid arguments are:
hosts
The list of hosts to scan, in a format understood by
Munin::Node::Configure::HostEnumeration. Required.
port
Port to connect to. Default is 161.
version
The SNMP version to use. Default is '2c'.
community
The community string to use for SNMP version 1 or 2c. Default
is 'public'.
username
The SNMPv3 username to use.
authpassword
SNMPv3 Authentication password. Optional when encryption is
also enabled, in which case defaults to the privacy password
("privpassword"). The password is sent encrypted (one way
hash) over the network.
authprotocol
SNMPv3 Authentication protocol. One of 'md5' or 'sha'
(HMAC-MD5-96, RFC1321 and SHA-1/HMAC-SHA-96, NIST FIPS PIB 180,
RFC2264). The default is 'md5'.
privpassword
SNMPv3 Privacy password to enable encryption. An empty ('')
password is considered as no password and will not enable
encryption.
Privacy requires a v3privprotocol as well as a v3authprotocol
and a v3authpassword, but all of these are defaulted (to 'des',
'md5', and the v3privpassword value, respectively) and may
therefore be left unspecified.
privprotocol
If the v3privpassword is set this setting controls what kind of
encryption is used to achieve privacy in the session. Only the
very weak 'des' encryption method is supported officially. The
default is 'des'.
The implementing perl module (Net::SNMP) also supports '3des'
(CBC-3DES-EDE aka Triple-DES, NIST FIPS 46-3) as specified in
IETF draft-reeder-snmpv3-usm-3desede. Whether or not this
works with any particular device, we do not know.
run_probes($plugins)
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.
