Nagios switch-check_mrtgtraf: Unable to open MRTG log file

[lsazzad]

Thanks a lot! You are life saver. Its working!

1. I am no clear about you following solution:

Please post your service configuration under Configure > Core Config Manager > Services and find the port 24 service and screenshot it.

Please note, i am using Nagios Core 4.0.8 Version. I cant find the Configure > Core Config Manager > Services path in GUI! I think its for Nagios XI.

2. Still having problem with MRTG graph GUI. Whenever i run cfgmaker for new switch it published the latest switch graph under my MRTG path:

Code: Select all

http://nagiosserver/mrtg

But in Nagios portal usage is being shown. I think its working from Background end.

A small update!

When i am trying to write

http://nagiosserver/mrtg/switchip_port.html

Its showing the graph. I think i can see all most all the switches graph. For me, its ok. Thanks in advance!

Would you help me to solve SNMP CRITICAL issue?

Could you post how you have configured your Port 24 Uplink settings?
What we need it to see how the check command is setup for this port.

[lsazzad]

In switch.cfg the config for SNMP is:

Code: Select all

define service{
	use					generic-service	; Inherit values from a template
	host_name			RR-DE-IP-Phone-SW-2		; The name we're giving to this switch
	service_description	        Port 24 Uplink-SFP Link Status
	check_command		check_snmp!-C public -o ifOperStatus.1 -r 24 -m RFC1213-MIB
	}

Execpt this i didn't modify anywhere.. Requested to let me know, if you need any information.

Can you please execute this command:

Code: Select all

/usr/local/nagios/libexec/check_snmp -H xxx -C public -o ifOperStatus.1 -r 24 -m RFC1213-MIB

Where xxx is the IP address of the switch.

Please show us the output.

[lsazzad]

Thanks for your query!

Code: Select all

root@RR-DE-NMS-2:~# /usr/local/nagios/libexec/check_snmp -H 172.19.254.61 -C public -o ifOperStatus.1 -r 24 -m RFC1213-MIB
SNMP CRITICAL - *up(1)* | 

[lsazzad]

It looks like you don't have the check_snmp plugin installed, see if /usr/local/nagios/libexec/check_snmp exists.

If you don't, you need to install the net-snmp packages and recompile your plugins:

Code: Select all

yum install net-snmp net-snmp-utils
cd /tmp
wget http://nagios-plugins.org/download/nagios-plugins-2.0.3.tar.gz
tar zxf nagios-plugins-2.0.3.tar.gz
cd nagios-plugins-2.0.3
./configure --with-nagios-user=nagios --with-nagios-group=nagios
make
make install

For MRTG graphs reference: http://nagios.sourceforge.net/docs/nagi ... raphs.html

A simple guide: http://bigunix.blogspot.com/2009/07/how ... g-and.html

I just installed net-snmp to my redundant nagios server. But facing same problem like previous. I have tried to re-install & recompiling net-snmp & all plugins. But no change

Please have kind look over above image!

To fix the critical message for your link status command, you need to change the command.
Change this from

Code: Select all

check_command      check_snmp!-C public -o ifOperStatus.1 -r 24 -m RFC1213-MIB

to

Code: Select all

check_command      check_snmp!-C public -o ifOperStatus.1 -m RFC1213-MIB

Save it out and restart Nagios and the Critical message will be fixed.

The MIB search path error, the default location "/usr/share/snmp/mibs/" could be missing the MIB files that are needed to run the check.
Can you verify that the RFC1213-MIB file is in that folder?

1. Thanks! Its working CRITICAL issue is fixed.

2. For MIB search path error i have recompile all the plugin again & its seems ok now.
