net-snmp

[hanya.radwan]

hi,

i installed net-snmp on redhat server, and add all MIBs but this server not send trap ?
shall I modify this parameter in snmptt.ini at nagios server "net_snmp_perl_best_guess = 0" to 1?

please I need way to check if remote host send trap or for tracing ?
please what is the best way to deal with traps or help document descrip that in details since I follow up the same steps in the user guide but not traps reach?

thanks,

[tmcdonald]

Let's check the basics:

Code: Select all

service snmptrapd status
service snmptt status
service crond status

Is the remote server not sending traps or is Nagios not receiving them? Or are you not sure which it is?

[hanya.radwan]

i run the command on Nagios server:-

[root@nms ~]# service snmptrapd status
snmptrapd (pid 31337) is running...
You have new mail in /var/spool/mail/root
[root@nms ~]# service snmptt status
snmptt (pid 41311) is running...
[root@nms ~]# service crond status
crond (pid 1854) is running...
regards remote server< I don't know, how can I debug that

How are you sending traps? Are you using Nagios XI and the SNMP Trap Sender component? Can you explain in details?

[hanya.radwan]

it is sending trap
I added rocommunity public 10.102.4.10 .1.3.6.1.2.1.1 to the /etc/snmp/snmpd.conf(remote host server)
snmp Ok:
/check_snmp -H 10.200.21.58 -o .1.3.6.1.2.1.1.3.0 -C public
SNMP OK - Timeticks: (435715) 1:12:37.15 |
also I try to check storage , an error appear:
[root@nms libexec]# ./check_snmp_storage.pl -H 10.200.21.58 -C public -m "^/$" -w 2 -c 4
ERROR: Description/Type table : Requested table is empty or does not exist.

OK you are talking about two totally different but related through the use of snmp, tasks. Are you attempting to run snmpd and have this system accessible for check_snmp checks against it, or do you want it to sent traps to your nagios instance on its own? Your initial comments indicate that you want this system to send to nagios, but your last two posts indicate that you actually just want to be able to use check_snmp against it, we need to clarify what exactly you are attempting to do.

[hanya.radwan]

I want the two options:
1- Nagios check server resources and logs
2-server send traps to Nagios

[tmcdonald]

Let's take a look at the traps first. Are you getting any entries in your /var/log/snmptt/snmpttunknown.log file relating to the traps? Are there any files in /var/spool/snmptt at all?

Also, can you please identify which IP is for the Nagios server and which is for the remote server to confirm?

[hanya.radwan]

no traps in the unknown related to our traps

and there are files in snmptt
[root@nms snmptt]# ls -ltr
total 12
-rw-r--r-- 1 root root 473 Sep 11 12:25 #snmptt-trap-1410427505042897

-rw-r--r-- 1 root root 476 Sep 11 12:25 #snmptt-trap-1410427506590022

nagios IP:10.102.4.10

remote server IP:10.200.21.58

[tmcdonald]

Can you post the contents of your /etc/snmp/snmptt.conf file please? Let's also take a look at your snmptt.ini:

Code: Select all

grep "mode =" /etc/snmp/snmptt.ini

Did you follow a particular guide for setting up SNMP traps? If so, please link to it.
