NAME
snmptrapfmt - Receive and log SNMP trap messages from a trap handler. SYNOPSIS
snmptrapfmt [-d num] [-D] [-f cfgfile] DESCRIPTION
Snmptrapfmt receives SNMP trap data through a local pipe. The trap data is written to this pipe by a SNMP trap handler which is called by snmptrapd (configuration is done in /etc/snmp/snmptrapd.conf) during the installation if this package. Snmptrapfmt formats the received trap data according to the specifications in the configuration file /etc/snmp/snmptrapfmt.conf (see this file for the syntax). The output of the snmptrapfmt application may be written to a log file or forwarded to the syslog daemon. The option -d 1 should be specified to enable tracing. Trace information is then written to the file /var/tmp/snmptrapfmt.trc. If the option -f cfgfile is given, the output of the daemon is configured via the mentioned configuration file. If this option is not spec- ified, a default output format is used. If the option -D is given, the the program will daemonize into the background. The syntax of the configuration file is explained in /etc/snmp/snmptrapfmt.conf ! FILES
/etc/init.d/snmptrapfmt is the start/stop script. /etc/snmp/snmptrapfmt.conf is the configuration file. /var/run/snmptrapfmt.pid is the PID file. /etc/snmp/snmptrapd.conf is the configuration file of the snmptrapd daemon, which calls the trap handler snmptrapfmthdlr. /usr/sbin/snmptrapfmt is the executable of the application. /usr/sbin/snmptrapfmthdlr is the executable of the trap handler. /var/run/snmptrapfmt.p is the communication pipe between the trap handler snmptrapfmthdlr and the formatter snmptrapfmt. /var/tmp/snmptrapfmt.trc is the trace file if the option -d is specified. /var/log/snmptrapfmt.log is the log file as specified in the configuration file.

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. SEE ALSO
