HOWTO: Very easy RPM based MRTG installation

[ProWebUK]

Before we go into it, this RPM was made by gpan (cheetaweb.com) and full credit goes out to him for this fantastic script!

log into your server as root and follow the information below.

# represents a command
// represents a comment

Disclaimer: The RPM is installed with no warranty of any kind and neither I, nor the makers of this RPM will take responsibility if it damages you server in any way, shape or form.

This version of MRTG has the following (Yes, a premade CFG is included :D ) :

- Traffic
- Open Connections

- Load Averages
- Swap memory
- Processes
- Uptime & idle time
- CPU Usage
- Memory Usage

Some may not work with DA, although i believe they all should. If you have any problems, comments or suggestions please post them in this thread :)

# mkdir mrtg

# cd mrtg

# wget http://prowebuk.com/files/mrtg/mrtg-2.9.17-4ct.i386.rpm

// if you wish to check the MD5, it is MD5: 013a1ee47032b6b7ab5147ca1960e56f

# rpm -Uvh mrtg-2.9.17-4ct.i386.rpm

// Check that a cron line for mrtg has not been added in /etc/crontab

// you can run MRTG by running the following command:

# service mrtg start

You may recieve errors the first few times you run this, if you wish to remove the errors run the following command until you get a simple message stating it is starting MRTG:

# service mrtg restart

// MRTG Will not run as default when you reboot your server, to fix this do the following:

# pico -w /etc/rc.d/rc.local

// at the bottom of the file add the following line:

/etc/rc.d/init.d/mrtg start

// exit and save by press ctrl & X, press y to save.

// You can now access your mrtg graphs by visiting:

http://SERVER_IP/mrtg/

Enjoy it!

ok, i have just realised DA does not like the mail and mrtg sections so here is the fix:

# pico -w /etc/mrtg/mrtg.cfg

// type ctrl & w to search and enter:

mail

// you should be highlighting the following section:

<br><a href="mail.html">- Mail Usage</a><br><a href="mq.html">- Mqueue Usage</a>

// You need to remove the following:

<br><a href="mail.html">- Mail Usage</a><br><a href="mq.html">- Mqueue Usage</a>

// once thats done type ctrl & w to search again, you need to search for:

mail

(again :D )

delete, from the following section to the bottom of the CFG)

#----------------------------------------
# Mail.cfg: Mailstats plotting with MRTG
#----------------------------------------


// you must also remove the mqueue section below the mail section

// to save the file press ctrl & x, press y to save.

//finally remove the no longer used files:

# rm /etc/mrtg/mqueue
# rm /etc/mrtg/mailstats

Someone has reported a missing dependency:

libpng.so.2

You may want try the suggestion provided by john (link 3 posts down :) )

Alternatively, you could *try* to do a fresh install of libpng :)

Chris

[l0rdphi1]

This looks very interesting. Looks like I'll be upgrading my MRTG to night :D

[interfasys]

Some of us have installed MRTG manually. Would it be possible to post the cfg and sh files somewhere (or provide instructions to remove the old one ;) )?

[ProWebUK]

Once logged in as root, go to wherever your mrtg is setup, go into the src directory and run the following command from there:

# make uninstall

from there you should be ok :) just go for your RPM install.

Chris

[ProWebUK]

Regarding the libpng.so.2 dependency problem you may want to try what John has suggested here: http://www.directadmin.com/forum/showthread.php?s=&threadid=1181

Chris

No src directory in /usr/local/mrtg-2

Maybe you meant the dir used to install mrtg? But no luck from there either unless I need to type ./configure, make, make uninstall ?

[ProWebUK]

Originally posted by interfasys
./configure, make, make uninstall ?

where you typed ./configure to install mrtg first time, type the following:

# cd /src
# make uninstall

[interfasys]

That's what I thought at first, but I got a:
make: *** No rule to make target `uninstall'. Stop.

There is only one file in the src dir : rateup.c

Is it safe to retype ./configure, etc. ?

[ProWebUK]

hmm in that case I am unsure.....

I suggest you stop your current MRTG and remove any cfgs you currently have to ensure that it doesn't get in the way!

Once you have done that try to install the rpm, i'm hoping it wont do any harm....

Chris

[interfasys]

Deleted /usr/local/mrtg-2, installed the rpm and I now have nice new graphs ;)

I hate to have fragments from old installs, but I'll take care of that later.

[ProWebUK]

glad to know its working for you :)

Chris

[l0rdphi1]

My graphs are being generated 0 bytes. It is updating though.

Probably related to what I did here (http://www.directadmin.com/forum/showthread.php?s=&postid=6446)? Can you post the RPM you found?

Help! :p

[ProWebUK]

all graphs?!?!

[l0rdphi1]

http://server1.liquenox.net/mrtg :eek:

[ProWebUK]

I will put my bet on saying the problem relates to libpng, mainly due to the fact libpng produces the graph, and no graphs have been generated....

[l0rdphi1]

Yeah. What RPM are you using for libpng? I think the one I installed doesn't work :)

[ProWebUK]

The problem *appears* to be another of the RH9 only problems. Give me 10... im trying to find the RPM's now :)

Chris

[ProWebUK]

remove the rpm you installed in the other thread and try this one,

ftp://speakeasy.rpmfind.net/linux/redhat/9/en/os/i386/RedHat/RPMS/libpng-1.2.2-16.i386.rpm

Keep us informed with how it goes :)

Chris

[l0rdphi1]

Here's what I'm getting:

libpng warning: Application was compiled with png.h from libpng-1.2.2
libpng warning: Application is running with png.c from libpng-1.0.13
gd-png: fatal libpng error: Incompatible libpng version in application and library

..and it won't let me remove libpng due to dependencies on bunches of other applications.

[ProWebUK]

http://forums.ev1servers.net/showthread.php?s=&threadid=22697&highlight=libpng+warning+Application+was+compiled+with+png.h+from+libpng1.2.2

read the post made by cpanelrcih, then there are soloutions 2 posts below.

Chris

[ProWebUK]

Note that the soloution is for cpanel, i suggest you ensure you have / can replace your current rpm's before removing :)

Chris

[ProWebUK]

... just read this also!

Remove every single libpng and then when you reinstall, make sure you DO NOT install the ones with "10" next to them.

you had to install the one with 10 that i thought stood out! lol

[l0rdphi1]

I'm back to libpng.so.2 is needed by mrtg-2.9.17-4ct again.

When installing gnome-libs it gave me:Failed dependencies:
ORBit is needed by gnome-libs-1.4.1.2.90-32
imlib is needed by gnome-libs-1.4.1.2.90-32
libIIOP.so.0 is needed by gnome-libs-1.4.1.2.90-32
libORBit.so.0 is needed by gnome-libs-1.4.1.2.90-32
libORBitCosNaming.so.0 is needed by gnome-libs-1.4.1.2.90-32
libORBitutil.so.0 is needed by gnome-libs-1.4.1.2.90-32
libgdk_imlib.so.1 is needed by gnome-libs-1.4.1.2.90-32
libpng.so.2 is needed by gnome-libs-1.4.1.2.90-32
so I skiped it.


So.. know where I can get a libpng.so.2 that works with RH9?

[ProWebUK]

try this link, it appears to be the only link i can find with redhat 9 and libpng.so.2!

http://www2.linuxforum.net/RPM/libpng.so.2.html

[l0rdphi1]

So http://www2.linuxforum.net/RPM/redhat/updates/7.3/en/os/i386/libpng-1.0.14-0.7x.4.i386.html I suppose?

[ProWebUK]

I guess so, libpng.so.2 is on the provides list, so if it installs it gives your server what it needs..... now we need to hope :)

Chris

[l0rdphi1]

Well.. this is not going to work.

How do I get it to stop trying to run every 5 minutes?

[l0rdphi1]

I gave up completely on this RPM mess and have switched back to the old method. However, I am still using a modified version of the RPM's cfg, which is cool.

http://server1.liquenox.net/mrtg :)

[interfasys]

Care to zip your cfg and sh files so that we have another way to get the same good looking graphs? ;)

[ProWebUK]

I believe the RH 7.3 installation is going smooth, have not yet seen any major problems :)

I suggest if you have a MRTG installed from source you just remove all configs and stop MRTG from running, I believe the RPM installs to a different directory to that of the compiled version I made a guide for.

Any problems feel free to post here :)

to uninstall it completely run the normal rpm -e on there

# rpm -e mrtg

can i ask what the error was with the previous libpng?

Chris

[ProWebUK]

LordPhi: I checked my RH9 box (which has mrtg running) and its running the following version:

libpng-1.2.2-16

Which can be found here:
http://rpmfind.net/linux/RPM/redhat/9/i386/libpng-1.2.2-16.i386.html

Now, the weird thing is i also have no libpng.so.2 and that RPM does *not* provide it, im thinking MRTG may have been compiled with the libpng built in..... if it has been i will consider making a DA specific RPM which could also save pretty much any work involved to get this working properly :)

Chris

[l0rdphi1]

My .cfg file and the data generator are loacted here (http://www.l0rdphi1.com/junk/mrtg.tgz).

They are working fine as of this afternoon, since I've fixed them.

However, note that the .cfg file is designed to run in /var/www/html/mrtg; you'll have to modify the the .cfg if you want to run it elsewhere.

[interfasys]

Clap clap clap!

[FarCry]

I have no problems on RH 7.3, only RH 8 servers.

Dont have any RH 9 servers....

[ProWebUK]

What are the problems with RH8?

[FarCry]

More than my calculator can count...

[l0rdphi1]

I have a question. On http://server1.liquenox.net/mrtg/cpu.html it is reporting that I am using on average 160.0 %CPU. What does that mean? A bug, or something?

Nothing to worry about, it seems all versions of this rpm (plesk cpanel and ensim) have it. Ii will look into a fix, for now there is no fix listed on its other guides.

Mark: can i ask what the problems were relating to? could you paste some of the errors?

When I try to use your files, I get a :
/usr/local/mrtg-2/bin/rateup: error while loading shared libraries: libgd.so.2

I have the file in /usr/local/lib/ and MRTG 2.10.11 did'nt complain when installing. Do you think it's an MRTG problem or a config file problem?


EDIT
Recompiled with indication of where to find the lib and it worked.

The gd library must be a different version with fc2 - either follow the source guide or you'll need to wait until i can get some rpms built up myself.

[Thafusion]

This is for RH but is there also something for Freebsd ?

[ProWebUK]

Compile it - theres a thread right below this 1 I believe ;)

[gpan]

Have you checked if the Core 1 packages work for you. If not I'll release some FC2 packages.

i downloaded your configuration file, there are two files inside.
one is called "system", the other is "mrtg.cnf"

my question is where to put that "system" file? and how come my mrtg looked so plain and simple, but yours looks much nicer?

http://65.75.183.160/mrtg/
http://server1.liquenox.net/mrtg/cpu.html

how do i make something like yours :confused:

thanks.

thanks. Hello,

You should be able to extract the whole thing to /var/www/html/mrtg, and then just tell mrtg to use the .cfg file.

MRTG will then show up at http://serverIP/mrtg or http://hostname/mrtg

i cannot download the mrtg rpm package.
would you mind post the link again ?

[matrixx]

Hi ,

The link Chris posted no longer works...

Does anybody have a copy of the RPM please?

Thanks,

Rob

[jlasman]

Surely someone downloaded this while it was available and still has it?

Thanks.

Jeff

[Auraka]

Guess this is dead now?

[snaaps]

Yes its dead!
Is there somewhere a mirror of this script?

Please tell me!

If anyone has it please let me know and I'll post it in my downloads section so anyone can get it.

Thanks.
