Bandwith Graphs show 0/0 in all network hosts.

[psasines]

Hello,

I've added some hosts, using Wizard "Network Switch / Router" on NAgios XI, version 2.17.4.
Nagios language is Eng.

The ping and status graphs are working properly however the bandwith graphics do not. They always display values 0/0.

Can you help me please?

Thank you.

Hello psasines,

The version number you have given does not seem to be correct. If you're running version 5.5.7 or 5.5.8. Running the following commands from terminal of your Nagios XI host will resolve your issue:

Code: Select all

chown "apache:nagios" /etc/mrtg -R
chmod 775 /etc/mrtg -R
chown "apache:nagios" /var/lib/mrtg -R
chmod 775 /var/lib/mrtg -R

Let us know if this resolves your issue. Thank you!

Hi,

Thank you for your reply.

After run the commands, the HP equipments(SNMP V2) start showing infomation, but de Cisco Equipments do not(SNMP V3).

Can you help?

Thank you

Hello psasines,

Does the Cisco equipment send any information at all to your Nagios Server? If so, can you tell me what data is being returned and what data isn not? Thank you.

Hi

After doing the troubleshooting I get the expected values, except for the errors that I send in the attachment (File Errors).

The other attachment is what you asked for.

I have this problem on all cisco equipment, eg:

SCT-DWIFI02-DC01
SCT-VMWARE-DC02
SCT-BACKUPIT-DC01
SCT-DLANIT-DC01

Thank you

Please run this command and send me the entire output:

Code: Select all

time LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg

Additionally, please run the commands from the PM I sent you and let me know the results.

[root@localhost ~]# time LANC=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg
-----------------------------------------------------------------------
ERROR: Mrtg will most likely not work properly when the environment
variable LANG is set to UTF-8. Please run mrtg in an environment
where this is not the case. Try the following command to start:

env LANG=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg

You had a typo in the command, you put in LANC in place of LANG.

Can you run the following commands as root and post the the /tmp/mrtg.txt file here?

Code: Select all

LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg -debug=cfg,base,log &> /tmp/mrtg.txt
LANG=C LC_ALL=C /usr/bin/mrtg &>> /tmp/mrtg.txt
