Hi,
Can anybody explain to me the correct way of setting and retrieving details
for a specific row in a mib table.
For example, I want to create a shared object to manage a table which holds
rows of data relating to counter values produced by a mail server.
Row 1 would hold status counters, such as total number of messages delivered
Row 2 would contain performance counters such as total number of messages
delivered in the last 10 seconds.
I want to be able to use snmpget to access just the performance counters
(i.e. all entries in the performance row), and also to access a specific
column value in that row.
So, lets say I define two entry objects in my table:
razorgateSmtpStatusCountersEntry OBJECT-TYPE
SYNTAX RazorgateSmtpCountersEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION "row holding values of status counters"
INDEX { razorgateTableIndex }
::= { razorgateSmtpCountersTable 1 }
razorgateSmtpPerformanceCountersEntry OBJECT-TYPE
SYNTAX RazorgateSmtpCountersEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION "Row to hold values of performance counters"
INDEX { razorgateTableIndex }
::= { razorgateSmtpCountersTable 2 }
So, the way we index rows in the table is by the razorgateTableIndex field.
For simplicity lets say my top level oid is 1.2.3
If I want to access the smtpdCountersTable I would use 1.2.3.1
If I wanted to access the first row in this table is it just a case of
using:
1.2.3.1.1
?
How then to I access a particular value in the first row, lets say total
number of messages delivered?
If I wanted to use names instead of numbers, how do I refer to a row in a
table? What name matches the index value?
Lastly, when loading my data into the table in the data access functions of
my shared object, how do I distinguish between the individual rows in the
table. In other words, if I get a get request for just the status counters
how do I decide that this should go in row 1 of the table.
Thanks,
Tim
