Munin Installation In Centos
Jun 25, 2008
I tried to install cacti, somehow it didn't work out so i decided to install munin. But when i choose munin from plugins list it starts to install than it says
Starting Munin Node: [ OK ]
Can't locate RRDs.pm in @INC (@INC contains: /usr/lib/perl5/site_perl/5.8.8/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.7/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.6/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.5/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl/5.8.7 /usr/lib/perl5/site_perl/5.8.6 /usr/lib/perl5/site_perl/5.8.5 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl/5.8.8/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.7/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.6/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.5/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl/5.8.7 /usr/lib/perl5/vendor_perl/5.8.6 /usr/lib/perl5/vendor_perl/5.8.5 /usr/lib/perl5/vendor_perl /usr/lib/perl5/5.8.8/i386-linux-thread-multi /usr/lib/perl5/5.8.8 . /usr/local/cpanel/3rdparty/lib/perl) at /usr/share/munin/munin-graph line 225.
BEGIN failed--compilation aborted at /usr/share/munin/munin-graph line 225.
Install Complete (munin 1.2.4)
Done
I did some googling about the error and it is because rrdtool is not installed.
Actually i installed rrdtool 1.3.0 from its website it was in /usr/local/rrdtool
Anyway i clicked install a rpm from whm and choose rrdtool.i386
root@server # rpm -qa | grep rrd
rrdtool-1.2.23-6.fc6
But it is still giving error above when i try to install munin

We like to create the mail accounts through php scripts in mywebsite.com website. So we request you to setup the Qmail with Vpopmail server in our server. As we have the following packages are already installed.
1. Qmail
2. Courier POP/IMAP
3. Horde Webmail client
Please install the vpopmail in the ourserver and configure these four packages to create the mail accounts via php script. So that we can use vaddsuer command in php to create the mail ids annd also imap_open commands to access the mails.
Our server is configured with Plesk control panel.
The installation is very urgent, as our website is going live sooner.
I will make the decision sooner and let us know the cost, as it will be given to the provider sooner.

I got this new server with FDC today, I asked for CentOS 5 minimal package installation, when I got the server I checked with rpm -qa |wc -l and seeing 572 packages. I have other CentOS 5 servers running with only 220 packages installed. So I asked the tech to reinstall it but he says the install is as minimal as the default install will allow. it doesn't seem right to me,

if after doing the following and transferring my domains to the server, they will functions properly as far as BIND setup is concerned. This will also serve as installation instructions for others if you can verify that this is all good.
I have installed BIND9 and setup DNS with the following:
------------------------------------------------------------------------
yum install bind-chroot
chmod 755 /var/named/
chmod 775 /var/named/chroot/
chmod 775 /var/named/chroot/var/
chmod 775 /var/named/chroot/var/named/
chmod 775 /var/named/chroot/var/run/
chmod 777 /var/named/chroot/var/run/named/
chown -R named /var/named/chroot/etc
chown -R named /var/named/chroot/var
cd /var/named/chroot/var/named/
ln -s ../../ chroot
cp /usr/share/doc/bind-9.3.3/sample/var/named/named.local /var/named/chroot/var/named/named.local
cp /usr/share/doc/bind-9.3.3/sample/var/named/named.root /var/named/chroot/var/named/named.root
touch /var/named/chroot/etc/named.conf
chkconfig --levels 235 named on
named.conf now contains:
Code:
options {
pid-file "/var/named/chroot/var/run/named/named.pid";
directory "/var/named/chroot/var/named";
query-source address * port 53;
allow-query { any; };
recursion no;
};
zone "server.mydomain.com" { type master; file "server.mydomain.com.db"; };
zone "mydomain.com" { type master; file "mydomain.com.db"; };
zone "mydomain.net" { type master; file "mydomain.net.db"; };
Upload named.conf to /var/named/chroot/etc
Modify /etc/resolv.conf to have the following before its current data:
search mydomain.com
nameserver 127.0.0.1
nameserver 78.129.143.155 // Replace this with the server's IP
// So below these there should be one or more nameserver $ip that point to the ISP's name servers so that the server can download stuff.
Modify /etc/host.conf to become the following:
order hosts,bind
multi on
nospoof on
Modify the files mydomain.com.db and mydomain.net.db and server.mydomain.com.db
to have the correct IP address. (These are DNS zone files that I'm sure are correct so I don't need you to confirm those.)
* Upload them to /var/named/chroot/var/named
/etc/init.d/named start

I have WHM 11.15.0 cPanel 11.17.0-R19429
FEDORA 4 i686 on standard - WHM X v3.1.0
/var keeps getting filled up with munin logs. Do I really need these logs? The server already had munin when I got it so I don't know how it was installed.
Can I disable it? I looked at the cron tab, and I don't see munin, but when I did chkconfig --list I found:
munin-node 0: off 1: off 2: on 3: on 4: on 5: on 6: off (spaces added because it made smileys)
How do I disable it?

if you can dump the actual data used to make the graphs in munin, or are the graphs the only way to view the data?

Munin was running OK on my cPanel server until yesterday when the graphs stopped updating themselves. I attempted a "/usr/share/munin/munin-update --force-root" which did nothing. Then I uninstalled and reinstalled munin on the cPanel plugins screen and now its running but all the graphs are empty

I use Munin to monitor the health of our servers, I can tell by looking at the graphs there's nothing to worry about, however, I'm struggling to baseline acceptable performance.what would be classed as 'normal' output for some of the more relevant munin graphs.
I've been looking at the Apache* modules and this is the output from one of our servers:
average of: 300 accesses per minute, 6 busy servers and 4.10MB a minute volume
max of: 1400 accesses per minute, 81 busy servers and 51MB a minute volume
This is a dedicated box running one site.
We have another box that is running approximately 30 sites
average of: 30 accesses per minute, 1 busy server and a 500K a minute volume
max of: 322 accesses per minute, 11 busy servers and a 4MB a minute volume.
These servers are pretty much the same spec, dual core 64Bit, 4GB of ram, two SATA disks in RAID1.

I'm checking my CPU/Memory/MySQL Usage and I'm seeing that something called Munin is running at 54%. That is apparently the average for today. Can anyone give me any insight as to what this is?
Wikipedia classifies Munin as a network monitoring application. I don't think it should be using this much processing.
It appears that I may have enabled this plugin when I rebuilt my apache using EasyApache. Are there any big benefits to this? Looking at the graphics at first glance it doesn't look like there is. but then again, I'm not that knowledgable about this stuff.

Does anyone have a tutorial or instructions to show how to set up munin to monitor bandwidth/traffic utilization?
I have a VPS from a provider that has no monitoring tools, and I need something to monitor.
(The VPS uses the HyperVM software.)
I am using the CentOS version 4.x right now, and munin is already set up and configured with a basic install.
Anyone know how to add traffic/bandwidth monitoring? (Ideally, it would monitor all active ports.. but I only really need it to monitor port 1194 for openVPN software.)

I rebooted my server and now munin is not showing any eth0 traffic. All other graphs are fine. I can see there is a ton of apache accesses so there is definitely eth0 traffic. Munin logs report no errors. I restarted munin and munin-node. I even did 'yum remove munin munin-node' and reinstalled again but it still doesn't work for eth0.

The memory usage on my server has slowly been creeping up over the last few weeks due to increased load. Here is my munin memory usage graph for the last week:
[url]
Could someone tell me what I need to be looking for or how to interpret this?
The cache and buffers have been getting really high but also has the inactive memory… so its looks as though its using memory and marking it as inactive afterwards and although graph shows I have massive memory use at first glace it also shows I have half my ram inactive and therefore available to be used.

On Cpanel/WHM. I have just moved from a VPS to a dedicated server. I reinstalled munin, so get some stats via that. I used to have apachetop loaded on my VPS for when I wanted a 'near realtime' streaming view of apache access.
I'm wondering what the best solution is to get a good view of apache, like what apachetop did, plus also it would be nice to have a real-time monitor of MySQL activity, HDD activity (such as I/O queues, etc. Something along the lines of the perfmon on Windows servers.
What is my best option?
Also, with Nagios, when I look at the website, it seems there are two options. Load it on a single server and then load the stats via [url]or have the Nagios 'stat collector' on one machine, and have it gathering stats from multiple machines.
If you only install it on a single dedicated server, do you really have to be on the console and connect to the Nagios stats via localhost, rather than connecting remotely?
Ideally, I would like a quick, easy to setup solution, but if it takes some configuring, I can deal with it, as long as there is some documentation. My main goal is to get the real time type monitoring, you get with window's perfmon.
