MRTG stopped working

I'm running mrtg on windows 2003 box and it stopped updating. Here is the error from the log.

Thanks for the help

My initial thought is that on the box 10.10.254.9 either:

the community name has changed
the IP address has changed
something has been installed/configured and is blocking access to port 161 (TCP or UDP) (like a firewall or IPCHAINS)
no longer has snmpd running

basically mrtg is saying I did not get an answer back, or I got back an answer I don't understand.

if i change the AbsMax: to equal or greater then the MaxBytes it updates but I just get a solid green area.

Also is the snmp comm. on the server or on the router

I have seemed to fix the problem. Each interface maxbytes setting was to high.

giltjr

Maxbytes is normally "detected" based on the type of interface it is. However there are times when the maxbytes of the interface may not be what you want.

Example: You have a gigabit interface that is only running at 100 Mbps. MaxBytes will be detected at 125MB, but you really want it set to 12.5 MB.

From your first post it was detected at 12.5 MB, which is 100 Mbps. What type of interface was there where this was too high?

Hello,
I am trying to plot graphs for my Brocade 4100 SAN switch and am using
Solaris 10, I am following the documentation given:
http://www.xolution.ch/mrtg/ i have written my config file:

~ snip
Target[switch.IP_0]:
1.3.6.1.4.1.1588.2.1.1.1.6.2.1.12.1&1.3.6.1.4.1.1588.2.1.1.1.6.2.1.11.1:public at fcswitch
Title[switch.IP_0]: fc throughput on switch fcswitch port 0 (mysun jnic0 slot7)
PageTop[switch.IP_0]: <H1>fc throughput on switch fcswswitch port 0 (mysun jnic0 slot7)</H1>

~snip

the error message i am getting is:

2008-08-26 12:03:22: WARNING: Skipping host fcswitch as it does not resolve to an IPv4 address
2008-08-26 12:03:22: WARNING: no data for

2008-08-26 12:03:22: ERROR: Target[xxx.xxx.xxx.xx_0][_IN_] ' $target->[0]{$mode} ' did not eval into defined data
2008-08-26 12:03:22: ERROR: Target[xxx.xxx.xxx.xx_0][_OUT_] ' $target->[0]{$mode} ' did not eval into defined data

can any one give me any insight on this, ??

The IP of the switch that i am using is what i read in my /etc/hosts file.

I used the same IP to plot the graphs for eth interface, using cfgmaker and
got the errors below. However in the output dir i did get some graphs, which
were not blank, they had some data in it;...isnt this contradicting to that
MRTG cannot resolve the switch IP. Also i can do a snmpwalk with this IP
address and community string public (UCD snmp version 4.2.1)

rajeevsrao,

You can not piggy back a question on somebody else's question, especially when it is closed. You will need to open your own question.
