Hi<br><br>I have a problem related to the error reported on using a mnesia table<br>with snmp.<br>I am trying to use a volatile table instead of mnesia, but I get the<br>following error when I do a snmpwalk on the OID<br><br>** User error: Invalid return value<br>{'EXIT',{{badmatch,false},[{snmp_generic,table_info,1},{snmpa_local_db,t<br>able_func,4},{snmpa_agent,get_next_values_all_rows,6},{snmpa_agent,get_n<br>ext_table,4},{snmpa_agent,next_loop_varbinds,5},{snmpa_agent,process_pdu<br>,4},{snmpa_agent,handle_pdu,7},{snmpa_agent,handle_info,2},{gen_server,h<br>andle_msg,6}]}} from<br>{snmp_generic,table_func,[{connectionTable,volatile}]} (get_next)<br><br>As far as I can tell, the value of false comes from the<br>snmpa_general_db:read function that can not find some key in the<br>internal store (which should be ets in my case)<br><br>Here is what I am trying to do:<br>Have a process that gathers statistics on my running application. This<br>process must then put the gathered stats into the volatile internal<br>store tables. The generic snmp access functions must then tretrieve the<br>info from the snmp table.<br><br>I create a new table with snmpa_local_db:table_create({connectionTable,<br>volatile}).<br><br>I have a function caled update that executes once a minute<br><br>update () -><br> Rows = function_that_gets_all_rows(),<br> lists:foldl ( fun(R,RowIndex) -><br> <br>snmpa_local_db:table_create_row({connectionTable,volatile},<br> [RowIndex],<br> R),<br> RowIndex+1<br> end,<br> 1,<br> Rows<br> ),<br> receive<br> after 60000 -><br> update()<br> end.<br><br>I can check this table with snmpa_local_db:print(connectionTable) and<br>all the entries are there.<br><br>Somehow I am missing some connecting bit.<br><br>My funcs file has a line<br><br>{smerlyConnectionTable ,{snmp_generic, table_func,<br>[{connectionTable, volatile}]} }.<br><br>And my MIB defines smerlyConnectionTable<br><br>Any help here would be appreciated.<br><br>-]-[einrich<br>
