snmptrapfmt(8) Receive and log SNMP trap messages from a trap handler.


snmptrapfmt [-d num] [-D] [-f cfgfile]


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 specified, 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 !

/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.
