Severity is not correct

[sonuma]

Hello,

For convert my MIBs, I use this command :

Code: Select all

snmpttconvertmib --in=FILE.MIB --out=FILE.CONF --exec='/usr/local/nagios/libexec/eventhandlers/submit_check_result $r "SNMP Traps" $s'

But I have a problem because when an CRITICAL trap is send to nagios, the status is not CRITICAL but INFORMATIONAL / NORMAL.

a example of snmptt.conf :

Code: Select all

EVENT wfmFSCRedundantFanFailed .1.3.6.1.4.1.3183.1.1.0.15101699 "Status Events" MAJOR
FORMAT FSC: Redundant fan failed: $2
EXEC /usr/local/nagios/libexec/eventhandlers/submit_check_result $r "SNMP Traps" $s "FSC: Redundant fan failed: $2"
SDESC
FSC: Redundant fan failed.
Variables:
  1: wfmTrapDetails
  2: wfmTrapType
EDESC

Where is the problem ?
my variable "$s" (in the EXEC line) is not recognized ?

Change MAJOR to Critical

Code: Select all

EVENT wfmFSCRedundantFanFailed .1.3.6.1.4.1.3183.1.1.0.15101699 "Status Events" Critical
FORMAT FSC: Redundant fan failed: $2
EXEC /usr/local/nagios/libexec/eventhandlers/submit_check_result $r "SNMP Traps" $s "FSC: Redundant fan failed: $2"
SDESC
FSC: Redundant fan failed.
Variables:
  1: wfmTrapDetails
  2: wfmTrapType
EDESC

Then:

Code: Select all

service snmptt restart

That should get you up and running.

I don't understand why this change resolve my problem because in "/usr/local/bin/snmptraphandling.py" script, there is an analyse of severity...and MAJOR is inside... ?

def get_return_code(severity):
severity = severity.upper()
if severity == "INFORMATIONAL":
return_code = "0"
elif severity == "NORMAL":
return_code = "0"
elif severity == "SEVERE":
return_code = "2"
elif severity == "MAJOR":
return_code = "2"
elif severity == "CRITICAL":
return_code = "2"
elif severity == "WARNING":
return_code = "1"
elif severity == "MINOR":
return_code = "1"
else:
printusage()
return return_code

When I launch manually the command :

Code: Select all

/usr/local/nagios/libexec/eventhandlers/submit_check_result SERVER_NAME "SNMP Traps" Critical "FSC: Redundant fan failed: $2"

The service status is OK

When I launch the same command but change "Critical" to "2" :

Code: Select all

/usr/local/nagios/libexec/eventhandlers/submit_check_result SERVER_NAME "SNMP Traps" 2 "FSC: Redundant fan failed: $2"

The service status is Critical.

Where is the problem ? Why my "$s" variable in EXEC command doesn't match correctly ? or how match 0,1,2 or 3 in place of Critical, warning...?

Ah, I see the issue.

Please follow this guide for setting up SNMP traps with Nagios XI:

https://assets.nagios.com/downloads/nag ... ios_XI.pdf

Then you will need to remove your entries from /etc/snmp/snmptt.conf

Then run this command on your MIBs to re-add them to snmptt the proper way:

Code: Select all

addmib /usr/share/snmp/mibs/YOUR-MIB

It would then looks something like this:

Code: Select all

EVENT wfmFSCRedundantFanFailed .1.3.6.1.4.1.3183.1.1.0.15101699 "Status Events" Critical
FORMAT FSC: Redundant fan failed: $2
EXEC /usr/local/bin/snmptraphandling.py "$r" "SNMP Traps" "$s" "$@" "$-*" "FSC: Redundant fan failed: $2"
SDESC
FSC: Redundant fan failed.
Variables:
  1: wfmTrapDetails
  2: wfmTrapType
EDESC

Notice the EXEC line is different.

Good

With the command ADDMIB, is it possible to choose the target file ? it's snmptt.conf by default...

[tgriep]

The addmib program is a bash script and you can edit it to output to a different file if you would like.
It is located in the /usr/local/bin folder.
