=head1 NAME
|
|
|
|
snmp__netapp_cifs - Munin plugin to retrieve cpu information from NetApp storage appliances.
|
|
|
|
=head1 APPLICABLE SYSTEMS
|
|
|
|
cpu should be reported by any NetApp storage appliance
|
|
with SNMP agent daemon activated. See na_snmp(8) for details.
|
|
|
|
=head1 CONFIGURATION
|
|
|
|
Unfortunately, SNMPv3 is not fully supported on all NetApp equipment.
|
|
For this reason, this plugin will use SNMPv2 by default, which is
|
|
insecure because it doesn't encrypt the community string.
|
|
|
|
The following parameters will help you get this plugin working :
|
|
|
|
[snmp_*]
|
|
env.community MyCommunity
|
|
|
|
If your community name is 'public', you should really worry about
|
|
security and immediately reconfigure your appliance.
|
|
|
|
Please see 'perldoc Munin::Plugin::SNMP' for further configuration.
|
|
|
|
=head1 INTERPRETATION
|
|
|
|
The plugin reports various cpu busy and idle.
|
|
|
|
=head1 MIB INFORMATION
|
|
|
|
This plugin requires support for the NETWORK-APPLIANCE-MIB issued by
|
|
Network Appliance. It reports the content of the cpu OID.
|
|
|
|
=head1 MAGIC MARKERS
|
|
|
|
#%# family=snmpauto
|
|
#%# capabilities=snmpconf
|
|
|
|
=head1 BUGS
|
|
|
|
This plugin wasn't tested on many hardware and only on Ontap 7.3.x.
