Hi,
How is the variable "id" initialized in row
MOTableRow<Variable> row =
moFactory.createRow(new OID(new int[] { id }), initialValues);
I do not see that anywhere.
Please fix your code first, before asking again. Also a simpler
code example would be helpful, which conentrates on the SNMP4J-Agent
code and not your project stuff.
Best regards,
Frank

Hi All and Frank,
Let me explain you the problem in bit detail.
I have created an SNMP Agent which supports v3 protocol. As you know
before start agent we have to register oid and table.
We are registering mo objects (MOScalar and MOTable) to snmp agent
using below code.
*server.register(mo, null);*
To create MO table we keep table configuration of table and scalar in
json structure. For example we want to register a motable with OID
.1.3.6.1.4.1.1.201.6.1 where .1 is table entry id.
where column information is mentioned in json format.
After createTableFromJSON method call (method detail in below
email) motable is successfully created and registered in DefautMOServer.
but once agent start and i try to set the value with the help of below
code.
VariableBinding binding = new VariableBinding();
binding.setOid(new OID(".1.3.6.1.4.1.1.201.6.1.2.1"));
binding.setVariable(new Counter64(20L);
server.setValue(server, null, binding);
Ideally 20L should be set for Column id 2 and row id or (Index id) 1
as mentiond and highlighted in blue. but value got copied over to all
rows.
Please let me know if i can call you on your number to describe you
the problem if i am not able to clarify it with this email.
Thanks in advance for help as i am very much stuck due to this
problem. Please help.
*JSON structure for registration*
{
"tableName": "table1",
"tableId": ".1.3.6.1.4.1.1.201.6.1",
indexValues: "1;2;3"
"columns": [
{
"columnName": "column1",
"columnOID": 1,
"dataType": 70,
"accessType": 1,
"defaultValue":0
},
{
"columnName": "column2",
"columnOID": 2,
"dataType": 70,
"accessType": 1,
"defaultValue":0
},
{
"columnName": "column3",
"columnOID": 3,
"dataType": 70,
"accessType": 1,
"defaultValue":0
},
]
}
*Method for MOTable creation*
*We are using this mofactory in below method *MOFactory moFactory =
DefaultMOFactory.getInstance()
public static MOTable<MOTableRow<Variable>, MOColumn<Variable>,
MOTableModel<MOTableRow<Variable>>> createTableFromJSON(
JSONObject data) {
MOTable table = null;
if (data != null) {
MOTableSubIndex[] subIndex = new MOTableSubIndex[] { moFactory
.createSubIndex(null, SMIConstants.SYNTAX_INTEGER, 1,
100) };
MOTableIndex index = moFactory.createIndex(subIndex, false,
new MOTableIndexValidator() {
public boolean isValidIndex(OID index) {
boolean isValidIndex = true;
return isValidIndex;
}
});
Object indexesObj = data.get("indexValues");
if(indexesObj!=null){
String indexes = data.getString("indexValues");
String tableOID = data.getString("tableId");
JSONArray columnArray = data.getJSONArray("columns");
int columnSize = columnArray.size();
MOColumn[] columns = new MOColumn[columnSize];
Variable[] initialValues = new Variable[columnSize];
for (int i = 0; i < columnSize; i++) {
JSONObject columnObject = columnArray.getJSONObject(i);
columns[i] = moFactory.createColumn(columnObject
.getInt("columnOID"),
columnObject.getInt("dataType"),
moFactory.createAccess(columnObject
.getInt("accessType")));
initialValues[i] =
getVariable(columnObject.get("defaultValue"));
}
MOTableModel tableModel = moFactory.createTableModel(new OID(
tableOID), index, columns);
table = moFactory.createTable(new OID(tableOID), index,
columns,
tableModel);
String[] indexArrString = indexes.split(";");
for(String indexStr: indexArrString){
MOTableRow<Variable> row =
moFactory.createRow(new OID(new int[] { id }), initialValues);
table.addRow(row);
}
}
}
return table;
}
