Monitoring Network Bandwidth

[tgriep]

I did a dump of the rrd file and it looks like there is valid data so can you run the following commands and post the output here?

Code: Select all

/usr/local/nagios/libexec/check_rrdtraf -f /var/lib/mrtg/192.168.2.240_6.rrd -w 500.0,500.0 -c 800.0,800 -l M -vv
rrdtool fetch /var/lib/mrtg/192.168.2.240_6.rrd AVERAGE -s-200minutes
rrdtool -v
/usr/local/nagios/libexec/check_rrdtraf -V

Here are the outputs:

Hi, it kind of solved the problem...I'm saying this because if I go to the service details and select "Performance Graphs", I see traffic (Attachment: "nagios_int8.jpg"). But if I see the list of all the interfaces, they all show "0Mbps" (Attachment: "nagios_int82.jpg").
I also attached the profile.


I'd like to add something I just saw. The "Database backend" show an error message stating "ndo2db is not running". Right next to the error there's an option to start it, I did it, bur nothing hapenned.
Thanks !

I am seeing some crashed MYSQL tables that should be fixed, login to the server as root, run the following to repair them.

Code: Select all

rm /usr/local/nagios/var/ndo.sock
rm /usr/local/nagios/var/ndo2db.lock
cd /usr/local/nagiosxi/scripts
./repair_databases.sh

After that, wait a few minutes and check to see if the Database Backend is running by running the following.

Code: Select all

service ndo2db status

If it says that it is running, wait 15 minutes and see if the bandwidth information is showing on the details screen and also the graphs.
If it is not running, post the error here.

Thanks a lot fo your help !!

[tgriep]

That is good to hear. Is it alright to close and lock the post as solved?

[rhonorio]

Yeah, sure.
