RE: DB locked ?

SNMP MIBs and SNMP traps

In NetXMS, MIBs are used only in MIB browser, to allow easier selection
of SNMP OIDs. To populate MIB browser with new MIBs, you should do the
following:

1. Put your new MIBs into MIB directory of your NetXMS server, usually
/usr/local/share/netxms/var/mibs on UNIX or C:\NetXMS\var\mibs on
Windows.
2. cd to your MIB directory
3. Compile all your MIBs together by running command

nxmibc -d .

You should get file netxms.mib updated.
Disconnect and reconnect your console. Console will notice changes in
MIB files and download updated netxms.mib to workstation. After that,
you will see new OIDs in MIB browser.

SNMP TRAPS

Short instruction for processing SNMP traps with NetXMS - copy/paste
from my another post, so it may look little strange:

First, you should create mapping between SNMP trap and NetXMS event. To
do this, go to View -> Control Panel -> SNMP traps. You will see some
default mappings for standard SNMP traps. Select Trap -> New... To
create new trap mapping. System will match trap OID to OID in map entry,
and if OID in map entry is shorter or equal to trap's OID, event
specified in map entry will be generated. To start, I suggest you to
create map entry with OID ".1" and event SNMP_UNMATCHED_TRAP. This will
match all traps with OIDs starting with ".1" (usually any traps). When
you have setup trap to event mapping, you should see generated events in
event log (View -> Event Log). If you wish to generate alarms or execute
programs when you receive SNMP trap, you should configure event
processing policy (View -> Control Panel -> Event Processing
Policy) to process SNMP_UNMATCHED_TRAP or any other events you generate.
In event processing policy you can specify that you wish to create an
alarm from event or perform some actions. Please note that if you wish
to do very granular processing of traps, most likely you will have to
create custom events, which can be done with event configurator (View ->
Control Panel -> Events).
Please note that server will process SNMP traps only for hosts
registered in database.

Additional comments:

1. You may use MIB browser for selecting trap OIDs from the MIBs you
have added - use "Select..." buttons in configuration dialogs.
2. If you have any ideas of improving trap configuration - send them to
the list, you are welcome.

Best regards,
Victor
