Okay, perhaps one more thing.
One of the SNMP trap lines is as follows:

enterprises.alcatel.nmu.genos.alarmHandoff.alarmHandoffObjects.alarmTable.alarmEntry.currentAlarmId. 3200904 = Counter32: 3200904

This code:

my $currentalarmid;
if ($msg_line[11] =~ m/currentAlarmId\.(?:[\d ]*)=([\S\s]+)$/) {
$currentalarmid=$1;
}

returns this value:

Counter32: 3200904

Which is of course correct.
I would like to have the value 3200904 only.

Of course the value 3200904 in the line changes all the time.
The rest of the line is fixed.

Would I completely understand the magic in "\.(?:[\d ]*)=([\S\s]+)$/" I may solve it myself, but since I don't .............

Any suggestions ?

Regards,

Erik

snmpinform

SNMPTRAP(1)							     Net-SNMP							       SNMPTRAP(1)

NAME

       snmptrap, snmpinform - sends an SNMP trap to a manager

SYNOPSIS

       snmptrap -v 1 [COMMON OPTIONS] [-Ci] enterprise-oid agent generic-trap specific-trap uptime [OID TYPE VALUE]...

       snmptrap -v [2c|3] [COMMON OPTIONS] [-Ci] uptime trap-oid [OID TYPE VALUE]...

       snmpinform -v [2c|3] [COMMON OPTIONS] uptime trap-oid [OID TYPE VALUE]...

DESCRIPTION

       snmptrap is an SNMP application that uses the SNMP TRAP operation to send information to a network manager.  One or more object identifiers
       (OIDs) can be given as arguments on the command line.  A type and a value must accompany each object identifier.   Each	variable  name	is
       given in the format specified in variables(5).

       When  invoked  as snmpinform, or when -Ci is added to the command line flags of snmptrap, it sends an INFORM-PDU, expecting a response from
       the trap receiver, retransmitting if required.  Otherwise it sends an TRAP-PDU or TRAP2-PDU.

       If any of the required version 1 parameters, enterprise-oid, agent, and uptime are specified as empty,  it  defaults  to  1.3.6.1.4.1.3.1.1
       (enterprises.cmu.1.1), hostname, and host-uptime respectively.

       The TYPE is a single character, one of:
	      i  INTEGER
	      u  UNSIGNED
	      c  COUNTER32
	      s  STRING
	      x  HEX STRING
	      d  DECIMAL STRING
	      n  NULLOBJ
	      o  OBJID
	      t  TIMETICKS
	      a  IPADDRESS
	      b  BITS

       For example:

       snmptrap -v 1 -c public manager enterprises.spider test-hub 3 0 '' interfaces.iftable.ifentry.ifindex.1 i 1

       will send a generic linkUp trap to manager, for interface 1.

OPTIONS

       snmptrap takes the common options described in the snmpcmd(1) manual page in addition to the -Ci option described above.

SEE ALSO

       snmpcmd(1), variables(5).
