getmany(1Msnmp)

getmany -- retrieve classes of objects from SNMP entity

Synopsis

getmany [-f defn_file] [-T timeout] entity_addr community_string object_name ...

Description

The getmany command is an SNMP application that retrieves multiple objects from an SNMP entity.

The arguments are the entity's address, the community string for access to the SNMP entity, and the object name(s).

The entity address can be either an IP address or entity name (if name-to-address resolution is enabled).

The community string used must be valid on the given entity. On UnixWare, community strings are kept in /etc/netmgt/snmpd.comm.

Object names must refer to a valid SNMP object or class of objects. Object names can be in the form of an identifier or the equivalent SNMP dot-notation. Identifiers for UnixWare SNMP objects are listed in ``UnixWare group and object descriptions'' in Configuring and administering SNMP. Equivalent SNMP dot-notation for these objects is defined in the files /etc/netmgt/nwumpsd.defs, /etc/netmgt/snmpd.defs, and /etc/netmgt/unixwared.defs. For a general explanation of SNMP dot-notation, see RFC 1213.

getmany retrieves a object class by first calling the SNMP entity with the object class name to get the first object in the class. Utilizing the GET_NEXT capability, it then calls the entity again using the object name returned in the previous call to retrieve the next object in the class.

For instance, running the following:

getmany suzzy public ipRouteDest

will traverse the network entity's ipRouteDest object class. The traversal of the object space stops when all of the classes being polled return a object of a class different than what was requested.

NOTE: A network entity's entire object tree can be traversed with a call of

getmany suzzy public iso

Options

The -f option is used to specify a file containing the mosy(1Msnmp) and post_mosy(1Msnmp) compiled list of object names and their numeric Object Identifiers, in addition to the objects in the standard MIB. This allows the user to dynamically augment the number of objects that can be recognized by the management utility.

The -T option can be used to specify the number of seconds the command will wait for a response from the entity specified by entity_addr. If not specified, this defaults to 20 seconds.
