Hi
I have no any problem with starting snmp with default mib_storage, but I got
error while trying to use mnesia as a mib_storage. Below you can find error
report message "Configuration error: [STANDARD-MIB]: configure failed:
{missing_mandatory,
  sysObjectID}", but sysObjectID is defined in standard.conf, so I can't get
is this my mistake or maybe a bug in snmp. Btw mnesia table
snmpa_symbolic_store was created.
snmp/snmp.config file:
[{snmp,
  [
  {agent,
  [
  {mib_storage, {mnesia, []}},
  {agent_verbosity, debug},
  {config, [{dir, "agent/conf/"}]},
  {db_dir, "cxDB/"},
  {local_db, [{repair,true},{auto_save,5000},{verbosity,debug}]}
  ]},
  {manager,
  [
  {config, [{dir, "manager/conf/"},
  {db_dir, "cxDB/"}]}
  ]}
  ]}].

snmp/agent/conf/standard.conf file:
{sysName, "CX"}.
{sysDescr, "Erlang/OTP Agent"}.
{sysContact, ""}.
{sysLocation, "Somewhere in Ukraine"}.
%%{sysObjectID, [1,3,6,1,4,1]}.
{sysObjectID, [0,0]}.
{sysServices, 72}.
{snmpEnableAuthenTraps, enabled}.
