snmp generic
SNMP Reference Manual
fmyTable, fsnmp generic, table func, [fmyTable, Db]gg.
In the functions defined below, the following types are used:
NameDb = fName, Dbg, Name = atom(), Db = volatile | persistent | mnesia
RowIndex = [int()]
Cols = [Col] | [fCol, Valueg], Col = int(), Value = term()
RowIndex denotes the last part of the OID which specifies the index of the row in the
table (see RFC1212, 4.1.6 for more information about INDEX). Cols is a list of
column numbers in the case of a get operation, and a list of column numbers and values
in the case of a set operation. Cols is a list of column numbers in case of a get
operation, and a list of column numbers and values in case of a set operation.
Exports
get status col(Name,Cols)
get status col(NameDb,Cols) -> fok, StatusValg | false
Gets the value of the status column from Cols.
This function can be used in instrumentation functions for is set ok, undo or set to
check if the status column of a table is modified.
get index types(Name)
Gets the index types of Name
This function can be used in instrumentation functions to retrieve the index types part
of the table info.
table func(Op1,NameDb)
table func(Op2,RowIndex,Cols,NameDb) -> Ret
Types:
Op1 = new | delete
Op2 = get | next | is set ok | set | undo
This is the default instrumentation function for tables.
The new function creates the table if it does not exist, but only if the database is
the SNMP internal db.
The delete function does not delete the table from the database since unloading
an MIB does not necessarily mean that the table should be destroyed.
The is set ok function checks that a row which is to be modified or deleted
exists, and that a row which is to be created does not exist.
The undo function does nothing.
The set function checks if it has enough information to make the row change its
status from notReady to notInService (when a row has been been set to
createAndWait). If a row is set to createAndWait, columns without a value are set
to noinit. If Mnesia is used, the set functionality is handled within a transaction.
