You could consider http://piwik.org/ .

I haven't used it myself but it looks like a decent alternative.

I guess I was thinking originally that you'd find the snmp configuration
more useful than anything really related to Nagios on that page.  Nagios
itself doesn't do graphing but some addons can utilize Nagios data to
produce graphs.  If you can successfully use snmpwalk on the remote system,
then at least you know snmp isn't the problem and you might not find that
article very useful.

You might have to use xm mem-max to set the maximum memory for the guest
prior to using xm mem-set.  Also, if you look at the man page for xm, you
will see the following for mem-set:

"Because this operation requires cooperation from the domain operating
system, there is no guarantee that it will succeed.  This command will
definitely not work unless the domain has the required paravirt driver."

So, there is no guarantee that you can increase/decrease the ram of a guest
without restarting it.

RPMForge has the latest stable Nagios release and I've had no issues with

Kate,

You need to modify /etc/aliases to have something like:

root:  u...@gmail.com


You should then run /usr/bin/newaliases to make these changes active.

If your having network apps hang, I would take a look at your /etc/hosts
file and make sure it is correct.  I've had an issue in the past with
sendmail hanging during boot and an incorrect /etc/hosts file was the cause.

Yeah, I guess you probably would and I can see how you would want to avoid
that.  That is how I do it with Cacti right now but depending on what your
using for virtualization, you might be able to pull all of those stats with
snmp on the host.

If your going to take this approach, why not just use your current cacti
setup and enable snmp on each of the hosts?  That seems like the simplest
and cheapest approach.

Just my thoughts.

Looking at the dates for the ISOs on the mirror I maintain, they are all
from Oct. 1st or 2nd.  Only the torrent files are from two weeks later.

The dates are likely based on when the ISO was actually created.  Therefore,
if the ISO was generated on Oct. 1st and no issues were found with it in QA,
then the date you are seeing on the mirrors is correct.  The ISOs are based
on the original 5.4 tree and don't include updates that Red Hat released
after the initial release of RHEL 5.4.

Indeed, I use the internal mirror that I run as well but I leave things set
as http://mirror/centos/$releasever/updates/$basearch/ instead of hard
coding it to 5.4 and the architecture.

Glad to hear it resolved itself automatically.  It probably just has
something to do with you trying to update so close to the official release
time.

Updating your repo file like this is a very bad idea.  You would be better
off waiting for the mirrorlist.txt file to update instead of causing
yourself more headaches in the long run.

That is a bit strange.  I would have expected the links to be
http://server/centos/*5*/blahblah instead of having 5.3. Is
your /etc/yum.repos.d/CentOS-Base.repo still the original version or has
someone customized it to look at 5.3 specifically?

Many of them should be current since the official release just occurred.
 I've already seen 25 Mbps jump in traffic on the Clarkson mirror since

You must be patient!  Many of the mirrors (including the one that I
maintain) are still syncing 5.4 due to issues that arose.  Wouldn't you
prefer to pull your packages from a mirror that won't give you 404s?  :D

StatusNet is basically an open source version of Twitter that you can deploy

Bernhard,

I'm actually probably the one that recommended the book to you.  I hope your
enjoying it so far.

As for your issue, I forwarded this to a friend of mine that is one of the
authors of the book.  He's interested in trying to fully understand what
you're trying to achieve.  He is wondering if you would mind sending an
email to cont...@runningxen.com with your issue and the specific page(s)
that you are referencing.  He also wanted me to make you aware of the
Running Xen readers mailing list, which you can find more information about
at http://runningxen.com/ .  You can also find several other resources for
the book on the site as well.

Feel free to keep me in the loop as well.  I might have some advice to offer
once I fully understand everything.

Re: [CentOS] virt-manager crashes Host during installation of guest

[Mathew S. McCarrell]

virt-install can be interactive if you supply a few necessary options
first.  I've put a sample of what I normally do below.

[r...@dom0 ~]$ /usr/sbin/virt-install -p --nonsparse -b xenbr0

What is the name of your virtual machine? 
How much RAM should be allocated (in megabytes)? 256
What would you like to use as the disk (path)? /xen/images/.disk

How large would you like the disk (/xen/images/) to be
(in gigabytes)? 5

Would you like to enable graphics support? (yes or no) no
What is the install location? http://mirror.clarkson.edu/centos/5.3/os/x86_64/

Also, if your willing to spend a few bucks, the Running Xen book is a great
source of information for anything relating to Xen (and I'm not saying that
just because I'm friends with several of the authors).  Also, you might find
the following slides useful.  http://cosi.clarkson.edu/docs/installingxen/

Re: [CentOS] virt-manager crashes Host during installation of guest

[Mathew S. McCarrell]

I definitely think if your new to Xen and are use to doing normal CD
installs, then virt-install is the easiest way to go.

Also, you could consider using prebuilt images that are already made
depending on your needs.  These can be found on stacklet.com.

Hope that helps,
Matt

Re: [CentOS] DNS Server Recommendations

[Mathew S. McCarrell]

You could get really simple if your a small shop and just use dnsmasq.
Although, I'm not sure it meets all of your needs.

Re: [CentOS] Strange XEN on CentOS HWaddr Address Issue

[Mathew S. McCarrell]

Brett,

I think the following link answers your question about the MAC changes.  You
may find more useful links on the resources page of the Running Xen site
http://runningxen.com/resources/.

http://lists.xensource.com/archives/html/xen-users/2006-02/msg00030.html

If you performed a fresh install without Xen, you would notice that it has
not permanently modified the MAC address of your system.

Hope that helps.

Re: [CentOS] no more single cd installs?

[Mathew S. McCarrell]

I've had no issues doing just base installs of CentOS 5.3 with only disk 1.
I would try again and double check that you only have base checked.

Make sure that you never put /boot on LVM because your machine will not

Re: [CentOS] Use 8GB RAM on Pentium D?

[Mathew S. McCarrell]

Neil,

I maintain a Dell PowerEdge 850 which has a Pentium D, exactly 8 GB of RAM,
and runs CentOS x86_64.  It should work fine as long as your motherboard
supports that much RAM.

Hope that helps.

Re: [CentOS] Question about dd (fill a hard disks' unused space with blanks)

[Mathew S. McCarrell]

In my previous experience, zeroing the disk will result in smaller files for
G4U but it will take awhile depending on many factors including the size of
the disk, performance, etc..
Also, I recommend giving Clonezilla (http://clonezilla.org/) a try.  It
offers more options than G4U and is more efficient in my experience.

Re: [CentOS] Random server reboot after update to CentOS 5.3

[Mathew S. McCarrell]

Actually, I've also been experience this issue on a two identical custom
built systems running 5.3 x64 with Xen.  I experienced the issue under the
same kernel that Peter is running and the first kernel released with 5.3.
In my particular instance, I'm attributing these random crashes to hardware
problems since I'm only experiencing the issues on these two systems and not
an older Dell PowerEdge 850 which is set up with the same software
configuration.

[CentOS] Local yum mirror and repomd.xml

[Mathew S. McCarrell]

Hey,

So, I'm having a minor issue.  Today, I configured one of our CentOS systems
to use our local mirror (mirror.clarkson.edu) for its repositories.  After
doing this, I ran a yum update and received the following warning in the
output along with the updates available:

Not using downloaded repomd.xml because it is older than what we have:
  Current   : Thu May  7 14:41:57 2009
  Downloaded: Tue Apr 28 05:04:32 2009

In order to get rid of this error, I ran "yum clean all" and then "yum
update" again.  This results in the warning no longer being present but also
results in yum telling me there are no packages marked for update.

Any thoughts on why this is occuring?  I've posted my mirror configuration
at the bottom of the page.

Thanks,
Matt
