ADDITIONAL METHODS

with_times

This is a modifier for any search() (including the helpers below) which will add the following additional synthesized columns to the result set:

uptime_age
last_discover_stamp
last_macsuck_stamp
last_arpnip_stamp

search_aliases( {$name or $ip or $prefix}, \%options? )

Tries to find devices in Netdisco which have an identity corresponding to $name, $ip or $prefix.

The search is across all aliases of the device, as well as its "root IP" identity. Note that this search will try not to use DNS, in case the current name for an IP does not correspond to the data within Netdisco.

Passing a zero value to the partial key of the options hashref will prevent partial matching of a host name. Otherwise the default is to perform a partial, case-insensitive search on the host name fields.

search_for_device( $name or $ip or $prefix )

This is a wrapper for search_aliases which:

  • Disables partial matching on host names

  • Returns only the first result of any found devices

If not matching devices are found, undef is returned.

search_by_field( \%cond, \%attrs? )

This variant of the standard search() method returns a ResultSet of Device entries. It is written to support web forms which accept fields that match and locate Devices in the database.

The hashref parameter should contain fields from the Device table which will be intelligently used in a search query.

In addition, you can provide the key matchall which, given a True or False value, controls whether fields must all match or whether any can match, to select a row.

Supported keys:

matchall

If a True value, fields must all match to return a given row of the Device table, otherwise any field matching will cause the row to be included in results.

name

Can match the name field as a substring.

location

Can match the location field as a substring.

description

Can match the description field as a substring (usually this field contains a description of the vendor operating system).

model

Will match exactly the model field.

os

Will match exactly the os field, which is the operating sytem.

os_ver

Will match exactly the os_ver field, which is the operating sytem software version.

vendor

Will match exactly the vendor (manufacturer).

dns

Can match any of the Device IP address aliases as a substring.

ip

Can be a string IP or a NetAddr::IP object, either way being treated as an IPv4 or IPv6 prefix within which the device must have one IP address alias.

search_fuzzy( $value )

This method accepts a single parameter only and returns a ResultSet of rows from the Device table where one field matches the passed parameter.

The following fields are inspected for a match:

contact
serial
module serials (exact)
location
name
description
dns
ip (including aliases)

carrying_vlan( \%cond, \%attrs? )


            

              
              
my $set = $rs->carrying_vlan({ vlan => 123 });

Like search(), this returns a ResultSet of matching rows from the Device table.

The returned devices each are aware of the given Vlan.

  • The cond parameter must be a hashref containing a key vlan with the value to search for.

  • Results are ordered by the Device DNS and IP fields.

  • Related rows from the device_vlan table will be prefetched.

carrying_vlan_name( \%cond, \%attrs? )


            

              
              
my $set = $rs->carrying_vlan_name({ name => 'Branch Office' });

Like search(), this returns a ResultSet of matching rows from the Device table.

The returned devices each are aware of the named Vlan.

  • The cond parameter must be a hashref containing a key name with the value to search for. The value may optionally include SQL wildcard characters.

  • Results are ordered by the Device DNS and IP fields.

  • Related rows from the device_vlan table will be prefetched.

has_layer( $layer )


            

              
              
my $rset = $rs->has_layer(3);

This predefined search() returns a ResultSet of matching rows from the Device table of devices advertising support of the supplied layer in the OSI Model.

  • The layer parameter must be an integer between 1 and 7.

get_models

Returns a sorted list of Device models with the following columns only:

vendor
model
count

Where count is the number of instances of that Vendor's Model in the Netdisco database.

get_releases

Returns a sorted list of Device OS releases with the following columns only:

os
os_ver
count

Where count is the number of devices running that OS release in the Netdisco database.

with_port_count

This is a modifier for any search() which will add the following additional synthesized column to the result set:

port_count

SPECIAL METHODS

delete( \%options? )

Overrides the built-in DBIx::Class delete method to more efficiently handle the removal or archiving of nodes.
