Change interface ID causes bandwidth monitor to fail

Post by dflick »

So I have been working on updating monitoring as we have moved a T1 from card 1 to card 2 in the router. I preformed the following steps and now my graphs and interfaces counters for bandwidth are all zero even though I see traffic on the router itself.

In CCM I updated the bandwidth service interface ID from the old id to the new (for example 11 to 12) and saved and applied the configuration.
I then went to the cfg file in /etc/mrtg/conf.d/ and commented the old interface section and uncommented the new interface section.
Then I went to /var/lib/mrtg and did a mv oldinterface.rrd newinterface.rrd
Back in CCM, I copied the newly updated interface and pointed that to a new interface that we brought up. I fixed the id on the copy and the name.

The result is that the copy works fine and pulls data but the interface that was updated shows zero bandwidth in and out although the router shows traffic. I have verified that that interface ID is correct and I have the same results for 5 out of the 6 I tried. Once works but for the life of me, I don't know what I did differently.

How can I fix the graphs for the moved interface while saving the history? The customer does not want to loose the history.

Just to confirm, there are about 20+ lines which make up just one interface. And the first six or so lines have the format SpecialText[xxx.xxx.xxx.xxx_1] where _1 is the port number.

### The Interface xx line is purely a comments line, it has no working purpose in the file.

Does that help?

Correct. How would I go about troubleshooting the rrd problem?

Re: Added monitored interfaces and graphs and counters died

Post by dflick »

I was running on empty last night trying to figure this out. Here is some more information which may help get to the bottom of the problem. The goal is to move the interface stats and counters from an existing monitored interface to a new interface. The method used was to go to CCM and edit the service for the bandwidth monitor to the correct value for the new interface. In the workflow below, I am moving the cable from interface s0/0/1:0 to S0/1/0:0 and I want all of the bandwidth charts to move with the interface so we keep the history.

First I got a list of interfaces from the router:

Code: Select all

Router#sh snmp mib ifmib ifindex 
Serial0/0/1:0: Ifindex = 28
Serial0/1/0:0: Ifindex = 29
I went into the GUI to Configure > Core Config Manager > Services and searched for my device. I selected the Bandwidth service and changed the Config Name, Description and $ARG1$ to the correct port number as shown by the Cisco CLI command above for bandwidth:
$ARG1$ 10.104.255.209_28.rrd Changed to 10.104.255.209_29.rrd

I try a Test Command Check and get this:

Code: Select all

COMMAND: /usr/local/nagios/libexec/check_rrdtraf -f /var/lib/mrtg/10.104.255.209_29.rrd -w 1000,1000 -c 1200,1200 -l K
OUTPUT: OK -[color=#FF0000] Current BW in: 0Kbps Out: 0Kbps|in=0Kb/s[/color];1000;1200 out=0Kb/s;1000;1200
I know this is incorrect because I see traffic on this interface:

Code: Select all

Serial0/1/0:0 is up, line protocol is up 
  Hardware is GT96K Serial
  Description: ATT AVPN DHEC302717.812
  MTU 1500 bytes, BW 1536 Kbit/sec, DLY 20000 usec, 
     reliability 255/255,[color=#FF0000] txload 4/255, rxload 18/255[/color]
I think this is the root of the problem.
I also noticed that the monitoring settings look a little off to me. For the new interface, I see this:
check_xi_service_mrtgtraf!10.104.255.209_29.rrd!1000,1000!1200,1200!K!!!!
This one has a bunch of extra exclamation marks at the end where a lot of my other interfaces on different routers do not.
The working interface on this router also has the extra exclamation marks so it may be nothing...

If I do that same test to the interface that I COPIED from this interface, it works fine.

Code: Select all

COMMAND: /usr/local/nagios/libexec/check_rrdtraf -f /var/lib/mrtg/10.104.255.209_27.rrd -w 1000,1000 -c 1200,1200 -l K
OUTPUT: OK - Current BW in: 115.25Kbps Out: 34.24Kbps|in=115.257695Kb/s;1000;1200 out=34.248656Kb/s;1000;1200
Now the only difference is that on the interface 29, I moved the rrd information from the old interface to the new one to save the history like this:
mv /var/lib/mrtg/10.104.255.209_28.rrd /var/lib/mrtg/10.104.255.209_29.rrd
Is that correct?

I also edited the file below to uncomment interface 29 and comment out interface 28 per instructions in another post.
vi /etc/mrtg/conf.d/10.104.255.209.cfg
Here is what those interfaces look like now:

Code: Select all

I noticed that this file seems to not do anything at all though as I changed the descriptions in the GUI and it is not reflected here. Also, changes to the descriptions here do not reflect in the GUI. What is this file used for and how is it used?

I also found some file in /usr/local/nagios/share/perfdata/Router but I am not sure if I need to do anything there. What are these directories used for and what information do they contain?

Re: Change interface ID causes bandwidth monitor to fail

Post by tgriep »

Could you run the following and post back the results?
I would like to check to see if there are any configuration errors and if the files are updating.

Code: Select all

LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lock/mrtg/mrtg_l
ll /var/lib/mrtg/

Here is the output requested. The other 3 interfaces are reporting well so I am thinking it is something I did when moving the history over. I am not sure if the process I used was correct.

Re: Change interface ID causes bandwidth monitor to fail

Post by dflick »

Support was able to determine that in the mrtg .cfg file, a port definition cannot start with a space, mrtg seems to ignore these lines. I had inadvertently left in a leading space when removing the comment before the interface definition.

Once we fixed this then mrtg correctly retrieved data.
