Hello,

I have install snmpd on my server Nagios.
I have also install snmpdtrapd but this file doesn't existe /var/run/snmptrapd.pid why?

service snmptrapd status

but no process found :
ps -ef | grep snmptrap*
root 18219 41325 0 15:27 pts/0 00:00:00 grep snmptrap*

I have convert a MIB with snmpttconvertmib and I have a file:
snmptt.conf like that:

EVENT ErrorInt .1.3.6.1.4.1.39015.13.990.0.1 "Status Events" Normal
FORMAT Trap erreur interface $*
EXEC /usr/local/nagios/libexec/eventhandlers/submit_check_result $r TRAP 1 "Trap erreur interface $*"
SDESC
Trap erreur interface
Variables:
1: Server_Number
2: Criticity
3: Timestamp
4: Code_Process
5: Return_Code
6: Desc
EDESC

but when I tried to test the OID .1.3.6.1.4.1.39015.13.990.0.1
The result is:
./check_snmp -H HOST_IP -P 2c -C 'public' -o ".1.3.6.1.4.1.39015.13.990.0.1"
SNMP OK - No Such Object available on this agent at this OID |

In the file /etc/default/snmpd, I have export all this MIBs:
export MIBS=CLIENTv4-MIB.txt => the Mibs file provided with the CLIENT that I have to supervise.
export MIBS=UCD-SNMP-MIB.txt
export MIBS=UCD-SNMP-MIB-OLD.txt
export MIBS=UCD-IPFWACC-MIB.txt
export MIBS=UCD-IPFILTER-MIB.txt
export MIBS=UCD-DLMOD-MIB.txt

export MIBS=NET-SNMP-EXAMPLES-MIB.txt
export MIBS=NET-SNMP-AGENT-MIB.txt
export MIBS=LM-SENSORS-MIB.txt
export MIBS=GNOME-SMI.txt

The question is why the ./check_snmp commande return this result ?

How can I do to supervise this mibs?

What version of Core are you using? Was it compiled from source or installed from distro repos? On what OS/version is nagios running? cat /etc/*-release may be of use.

Posted: **Wed Dec 14, 2016 3:44 am**

Hello,
The os version is:
cat /etc/*-release
PRETTY_NAME="Debian GNU/Linux 8 (jessie)"
NAME="Debian GNU/Linux"
VERSION_ID="8"
VERSION="8 (jessie)"
ID=debian
HOME_URL="http://www.debian.org/"
SUPPORT_URL="http://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

I have install the core Version 4.1.1
with this package: wget https://assets.nagios.com/downloads/nag ... 1.1.tar.gz

Thanks

Take a look at the link below for a how to setup a Nagios server to receive traps. It is geared towards Centos but you could look at it for reference.
http://askaralikhan.blogspot.ca/2010/12 ... agios.html

Can you run the following command and post the output so we can see the permissions of the /var/run folder?

Code: Select all

ls -l /var[/code

The check_snmp command output could be either the device is not responding to that OID or that the check command is not searching through all of the MIB files on the Nagios server.

To fix that, follow these instructions.
Create the file /etc/snmp/snmp.conf, and put into it:
[code]mibs +ALL

This tells the snmp commands that they should load ALL of the mibs when they are ran.
Save the file, quit.
Now retest the check_snmp command and see if it works.

ls -l /var/run
lrwxrwxrwx 1 root root 4 Nov 2 05:49 /var/run -> /run

I have adding "mibs +ALL" in the file /etc/snmp/snmp.conf

and the result is the same:
./check_snmp -H 10.9.3.69 -P 2c -C 'public' -o ".1.3.6.1.4.1.39015.13.990.0.1"
SNMP OK - No Such Object available on this agent at this OID |

When I have restarted the snmpd service after the file modification, I see this message.

In this topic, it showing how to configure and running the snmptrapd demon

# vi /etc/sysconfig/snmptrapd.options
#OPTIONS="-On -Lsd -c /etc/snmp/snmptrapd.conf -p /var/run/snmptrapd.pid"
OPTIONS="-On -Lsd -p /var/run/snmptrapd.pid"

Which file can I update in debian 8 ? /etc/default/snmpd ?

In /var/run I have a symbolic link from /run
in /run I have not the file snmptrapd.pid

However the snmp packages are install.

My question to you is all you want it to get the Nagios system to receive SNMP Traps, correct?
If this is true, you will have to install the snmptrapd and the snmptt packages and get them to run without any errors.
If you did an apt-get to install the snmptrapd daemon, I would remove it and reinstall it as that daemon is not running and you may have to look in to the log files to get better information on why is it not working.

The snmpd daemon is only needed if you want to poll the nagios server but it is not needed for the server to receive traps so ignore that issue for now.

=> YES I want.

I followed the reference : http://askaralikhan.blogspot.ca/2010/12 ... agios.html

But the check_snmp allways return :

This message let me think that there is nothing at this OID on this server agent. Is it possible?

When you run the check_snmp plugin, it is trying to poll the device for that OID and that device is not responding to the poll or that the MIB file is not installed on the system the check_snmp is run on.

The snmptrapd and the snmptt daemons are for traps only and are for receiving SNMP traps and cannot be polled by using the check_snmp command.

If you want to poll that device, you will need to enable the device to be polled.
It the device at IP address 10.9.3.69 is a linux system, you will need to install the snmpd daemon and configure it so it will respond the the check_snmp.

Setting up SNMP Traps is a separate process than the snmpd daemon with separate settings.

Can you provide more details about the device at IP address 10.9.3.69?
