snmptrapd trap variable value truncated
I have configured snmptrapd to log the traps to log file. the traps received and logged ok based on the mib file definition.

there is only one problem.

the value of one of the variables seems to be truncated due to end of line or some special char.

Code:
linux is centos 6.2
snmp software versions:
net-snmp-5.5-27.el6.x86_64
net-snmp-libs-5.5-27.el6.x86_64
net-snmp-utils-5.5-27.el6.x86_64
net-snmp-perl-5.5-27.el6.x86_64

Trap definition from the MIB:

Code:
EVENT fredFault .1.3.6.1.4.1.1383.1008.0.50 "Status Events" 
This trap is sent if a device is not reachable using IP ping
Variables:
  1: alarmId
     Syntax="OCTETSTR"
     Descr="OMC unique alarm id"
  2: deviceName
     Syntax="OCTETSTR"
     Descr="Name of device"
  3: deviceType
     Syntax="INTEGER"
     Descr="Type of device such as WEB, VAD, etc."
  4: severity
     Syntax="INTEGER"
     Descr="severity of trap"
  5: timeStamp
     Syntax="OCTETSTR"
     Descr="time that the trap was sent. YYYYMMDDHHMMSS"
  6: description
     Syntax="OCTETSTR"
     Descr="short description of trap."
  7: text
     Syntax="OCTETSTR"
     Descr="full description of trap."


Below is the log from syslog file

Code:
##HOSTNAME## Hostname of the device sending the alarm
##IP##       IP address of the device sending the alarm

May  6 03:13:12 nms snmptrapd[26523]: 2012-05-06 03:13:12 ##HOSTNAME##  [##IP##] (via UDP: [##IP##]:45364->[10.102.4.10]) TRAP, SNMP v1,  community public#012#011.1.3.6.1.4.1.1383.1008 Enterprise Specific Trap  (50) Uptime: 205 days, 11:48:19.09#012#011.1.3.6.1.4.1.1383.1008.1.7.0 =  STRING: "567349"#011.1.3.6.1.4.1.1383.1008.1.1.0 = STRING:  "sgf.domain"#011.1.3.6.1.4.1.1383.1008.1.2.0 = STRING:  "ASU"#011.1.3.6.1.4.1.1383.1008.1.3.0 = INTEGER:  4#011.1.3.6.1.4.1.1383.1008.1.4.0 = STRING:  "20120426132231"#011.1.3.6.1.4.1.1383.1008.1.5.0 = STRING: "ASU EVENT:  Alarm already raised For App ID  4 and Event ID  110 (Confusion message  received for CIC:"#011.1.3.6.1.4.1.1383.1008.1.6.0 = STRING: "No Alarm  is present in the Alarm Table for the given AlarmID - ID=5 SEVERITY=INFO  STATUS=ALARM_ACTIVE No Alarm is present in the Alarm Table for the  given AlarmID - ID=5 SEVERITY=INFO STATUS=ALARM_ACTIVE No Alarm is  present in the Alarm Table for the given AlarmID - ID=5 SEVERITY=INFO  STATUS=ALARM_"

Problem

the variable 6: description seems to be truncated, as follows:

- values that supposed to appear is

Code:
ASU EVENT: Alarm already raised For App ID 4 and Event ID 110 (Confusion message received for CIC: 29, DPC: 6-0-2)

- the value truncated and appeared at the log file

Code:
ASU EVENT: Alarm already raised For App ID  4 and Event ID  110 (Confusion message received for CIC

And how? Many thanks for nothing.

It might be that the stony silence your first post was met with has to do with other people doing the same you do right now: having a solution for your problem but not bothering to share it with others.

Think about it - and i really do hope that helps.

there is no problem at all, i get the message already truncated. so i didn't post any comment.

Actually the issue occurs because i got the trap forwarded from another snmp trap agent. so, it was truncated there.

Ahh - good to know. See, *this* is an explanation others might be able to make use of when they have the same or similar problem: check, if there isn't another snmp-agent which truncates the message already.

This makes all the difference between having the opportunity to learn something and wasting our collective time.

Thank you - this is meant in earnest.
