Processes Description Polling specified IP for getting the System group objects Listening & Receiving a trap from the agent if it is running SNMP service Storing SysUpTime and Trap timestamp at DB for the responding Agent name Retrieving the previous record for this Agent name Comparing the two records to check out failures at a specific period

Inside Java Code Pollingl_SNMPVarBindList.addVarBind(" ");l_SNMPVarBindList.addVarBind(" ");l_SNMPVarBindList.addVarBind(" ");l_SNMPVarBindList.addVarBind(" ");l_SNMPVarBindList.addVarBind(" ");l_SNMPVarBindList.addVarBind(" ");l_SNMPVarBindList.addVarBind(" "); l_SNMPRequest = l_SNMPSession.snmpGetRequest( null, l_SNMPSession.snmpGetRequest( null, l_SNMPVarBindList ); l_SNMPVarBindList ); boolean completed = l_SNMPRequest.waitForCompletion( p_lWaiting );

Inside Java Code Listening l_SnmpEventReportDispatcher = new SnmpEventReportDispatcher( 162 ); l_SnmpEventReportDispatcher.addTrapListener( new TrapListenerImpl(new TextArea()) ); new Thread(l_SnmpEventReportDispatcher).start(); Receiving l_vSystemObjects = new Vector(7); for( int j=0; j < 7; j++ ) {l_vSystemObjects.add( ((SnmpVarBind)l_SNMPVarBindList.elementAt(j)).getStringValue() ); ((SnmpVarBind)l_SNMPVarBindList.elementAt(j)).getStringValue() );}

Inside Java Code Retrieving StringBuffer l_szQuery = new StringBuffer("select * "); l_szQuery.append("from "); l_szQuery.append("TTCSE552.CSE_552_TB "); l_szQuery.append("where NAME = ? order by TRAP_TIME desc"); PreparedStatement l_pstmtQuery = p_DBConnection.prepareStatement(l_szQuery.toString()); l_pstmtQuery.clearParameters(); l_pstmtQuery.setString( 1, p_szName ); ResultSet l_rsQueryResult = l_pstmtQuery.executeQuery(); if ( l_rsQueryResult.next() ) { l_LastPolling = new LastPolling(); l_LastPolling.setName ( l_rsQueryResult.getString ("NAME")); l_LastPolling.setTrapTime( l_rsQueryResult.getTimestamp("TRAP_TIME")); l_LastPolling.setUpTime ( l_rsQueryResult.getInt ("UP_TIME")); }l_rsQueryResult.close();l_pstmtQuery.close();

Inside Java Code Storing StringBuffer l_szInsert = new StringBuffer("insert into "); l_szInsert.append("TTCSE552.CSE_552_TB "); l_szInsert.append("(NAME, TRAP_TIME, UP_TIME) "); l_szInsert.append("values (?, ?, ?)"); PreparedStatement l_pstmtInsert = p_DBConnection.prepareStatement(l_szInsert.toString()); l_pstmtInsert.clearParameters(); l_pstmtInsert.setString ( 1, p_szName ); l_pstmtInsert.setTimestamp( 2, p_dtTrapTime ); l_pstmtInsert.setInt ( 3, p_nUpTime ); if (l_pstmtInsert.executeUpdate() > 0) { l_nErrorCode = 1; }l_pstmtInsert.close();

Inside Java Code Detection int l_nUpTimeDif = p_nUpTime - p_nDBUpTime; long l_lTrapTimeDif = p_dtTrapTime.getTime() - p_dtDBTrapTime.getTime(); int l_nTrapTimeModulated = (int)l_lTrapTimeDif/1000; String l_szMessage = null; int l_nDif = l_nTrapTimeModulated - l_nUpTimeDif; if( l_nDif < 120 ) l_szMessage = "No failure since the last polling"; else l_szMessage = "A failure has occurred from less than " + l_nDif + " seconds"; return l_szMessage;
