Creating SNMP Strings To Trap ALOM Console Messages
Greetings To All!
I am trying to accomplish the following:
Using a public SNMP string, create a trap which will trap ALOM console messages on a Solaris Sunfire T-1000 ALOM console. The platform is Solaris 10. These newly created traps need to be configured in such a way that they will send trapped ALOM console messages to a log file.
I have visited the docs.sun.com website as well as other websites and was able to find some background information, but not enough to put together a complete game plan. Specifically, I am missing the following information:
(1) The configuration file or files where I would configure the SNMP traps
(2) What process or processes/daemons need to be enabled/configured so as to implement/enable SNMP trapping
(3) The name of the log file where the results of ALOM console message trapping results would typically be routed to.
I think I have it all covered in steps 1-3 above, but if I am missing something or leaving something out, then I am not averse to being corrected and/or admonished. As I stated previously, I have visited several websites looking for enough information, but cannot seem to get it all altogether. I would deeply appreciate anyone who has ever done this before to share his/her advice/experience/notes with me. Thanks in advance!

send_v2trap
NETSNMP_TRAP_API(3) Net-SNMP NETSNMP_TRAP_API(3)
NAME
send_easy_trap, send_trap_vars, send_v2trap - send TRAPs or INFORMs from a Net-SNMP MIB module
SYNOPSIS
#include <net-snmp/agent/agent_trap.h>
void send_easy_trap(int trap, int specific);
void send_trap_vars(int trap, int specific, struct variable_list *vars);
void send_v2trap(struct variable_list *vars);
DESCRIPTION
These three routines may be used to send traps from a MIB module within the Net-SNMP agent (including an AgentX subagent).
send_easy_trap() sends an SNMPv1 trap (or the SNMPv2 equivalent) to the list of configured trap destinations (or "sinks"), using the pro-
vided values for the generic trap type, and specific trap value.
send_trap_vars() is similar, but appends the supplied list of variable bindings to the traps that are sent.
send_v2trap() uses the supplied list of variable bindings to form an SNMPv2 trap, which is sent to SNMPv2-capable sinks on the configured
list. An equivalent INFORM is sent to the configuredq list of inform sinks. Sinks that can only handle SNMPv1 traps are skipped.
The various "send_trap()" calls allow you to specify traps in different formats. And the various "trapsink" directives allow you to spec-
ify destinations to receive different formats. But *all* traps are sent to *all* destinations, regardless of how they were specified.
I.e. it's
___ trapsink
/
send_easy_trap ___ [ Trap ] ____ trap2sink
___ [ Generator ]
send_v2trap / [ ] ----- informsink
____
trapsess
*Not*
send_easy_trap -------------------> trapsink
send_v2trap -------------------> trap2sink
???? -------------------> informsink
???? -------------------> trapsess
WARNINGS
These routines are used to send the traps immediately they are called. Invoking them at the appropriate time is left to the MIB module
programmer.
