View 2 Replies View RelatedI installed MRTG some hours ago. Everything works fine (disk, cpu,..), except the network graph.
For this graph, it's only work for ~3 cycles (15min), then... nothing.
This is the part of mrtg.cfg:
Code:
The number for eth0 is 3
Code:
SNMP is running:
Code:
Crontab is configured for mrtg (and seems it's not the problem because the other graphs works well):
Code:
In attachement is the graph for the memory (working!) and .. for the network, as you can see, only one small pic at the beginning.
My mrtg refreshes usually too late(15 min.)and i want to make it 5 min.But i dont know where to edit.

I'm using mrtg to generate html files. With mrtg , i use indexmaker . Inside html files , i have found some html tag like "<SMALL>some text</SMALL>".
There is the manner to delete text inside two tags ? With bash script?
i have done most of the setup for MRTG network monitor tool.
But i m stuck at configuration part.
the actual MRTG guide says following.
I m little confused about what should i put inplace of community@router.abc.xyz.

The next step is to configure mrtg for monitoring a network device. This is done by creating an mrtg.cfg file which defines what you want to monitor. Luckily, you don't have to dive straight in and start writing your own configuration file all by yourself. Together with mrtg you also got a copy of cfgmaker. This is a script you can point at a router of your choice; it will create a mrtg configuration file for you. You can find the script in the bin subdirectory.
cfgmaker --global 'WorkDir: /home/httpd/mrtg'
--global 'Options[_]: bits,growright'
--output /home/mrtg/cfg/mrtg.cfg
community@router.abc.xyz
This example above will create an mrtg config file in /home/mrtg/cfg assuming this is a directory visible on your webserver. You can read all about cfgmaker in cfgmaker. One area you might want to look at is the possibility of using --ifref=ip to prevent interface renumbering troubles from catching you.
If you want to start rolling your own mrtg configuration files, make sure you read mrtg-reference to learn all about the possible configuration options.
I ahve configured MRTG to generate bandwidth utilization graphs of Network devices.
I ahve configured 30 Network device ( Cisco Switches and Routers), For most of the devices MRTG is working fine but for some devices it is not able to generate log file and giving the following error:

We have to get this information by snmp.The items we need are:
1-In Byte Transferred on every network interface
2-Out Byte Transferred on every network interface.
3-Memory Usage
4-Memory Free
5-CPU usage
6-Free Disk space on partiotion
7-Uptime

I have been trying to set up SNMP monitoring using Cricket. I believe I have Cricket running fine, however I also believe that I have SNMP set up wrong. When I do an SNMPWALK I get the following:

This tells me I have SNMP running, however I would expect to see a lot more data... Am I correct, should I see more data? I spoke to a friend, and he suggested that I have something not set up correctly in SNMP dealing with the community string...
I just narrowly passed another exam on UNIX Academy. Their DVDs are incredible. While I made some mistakes here and there.I was really stumbled upon a question that was formulated something like "SNMP for managing Linux machines remotely".I can't remember the exact definition. I'm not sure what it was about.I was under impression that SNMP it is a carrier protocol for commands like "ping" and "traceroute". I was trying to read about it online but it is way too broad and technical, they're loosing me on very first page. I suspect there's some kind of product or technology that uses SNMP in some way to handle Linux, I'm not sure.
View 2 Replies View RelatedIam using snmp to access the remote system data.But according to the requirement iam encoding the snmp request data to OAMPDU packet format and sending to remote system.the remote system receives the OAMPDU packet,decodes it and is sending the snmp packet to snmp agent through UDP socket which is bind to port 161.but iam unable to receive the response from snmp agent.i have created a udp socket which is bind to 161 port to receive the response.
if i use any other free port number other than 161 for receiving snmp agent is not sending the response to that port.can any one please suggest me how to overcome this problem.Can we configure the different ports for tx,rx ?How do we know on which port does snmp sends the response ???
I need to be able to send snmp traps based on certain severity or content of syslog messages. Can this be done from standard linux? Alternatively, are there MIB's out there that support syslog events so I can get the status from snmp?

View 2 Replies View RelatedI am trying to calculate band Width on few interfaces. Every thing works fine, bandWidth goes up when user loged in it goes down the moment working hrs are over. Only problem is once in a while it show negative bandWidth ? I make that script to send information in-case it negative. here are few examples
Code:
from IP XX.X.X.X interface X
inCounters new = 1056124169 old = 484753332
outCounters new = 71539457 old = 4205963496
inDelta = 571370837

Code:
inPut utilization = (change x 8 X 100) / (change in time X connection speed)
but that would not matter because , problem is caused by lowering count on in and out packets.

View 1 Replies View RelatedI recently migrated my mail server over to a new machine. For some reason, after verifying that the OIDs are correct, MRTG won't graph anything. I've quadruple checked the OIDs and used the strings as well, it won't graph at all. Graphs for RAM, ethernet, packets, etc. are working. CPU is the only thing not working. They work when I use snmpwalk with them and they do populate values. The logs show unknown SNMP vars for cores 1 & 2, but there's no mention of cores 3 & 4 entries in the logs.
