Hi guys

I'm trying to install NagVis and it seems that something goes wrong. The question is why? I've tried to follow the dokumentation -> http://assets.nagios.com/downloads/nagi ... ith_XI.pdf, but...

I can see there are a problem at the dependency resolvation. Does it make sense to any of you?

The PHP part I'll probably need to take a look at - things got a bit weird when they added 5.3 to the repo as a separate package. The graphviz part looks like an error on the part of the EPEL admins.

EPEL admins? Did I miss something in the documentation? As I mentioned in another thread, I'm running Nagios XI on a VM server ESX 4.1 with VM tools installed.

EPEL is a third-party package repository for Red Hat and CentOS - http://fedoraproject.org/wiki/EPEL. The people running that are responsible for making the packages all work nicely with each other, and I suspect a failure on that point here.

Any news on this yet?

I'm trialling various Nagios-based products, incl. Nagios XI. I do like the look of NagVis, which I've played with on OpsView. I prefer the functionality/look of Nagios XI, but the non-functioning NagVis is holding me back from recommending it to my boss!

Is there a manual workaround for installing it?

We are trying to fix the "php53-common conflicts with php-common" error. We will have to work on our install script to reflect the latest changes in php. There is a bug report posted on the bug tracker. You can see it at:
http://tracker.nagios.com/view.php?id=169
There is a possible bug in yum as well or at least an issue with the way how repositories are laid out configured. There is more information here:
http://bugs.centos.org/view.php?id=4927#c12857

I have tried a "workaround" solution - not very pretty but it worked on my test machine. You can try it at your own risk.
Run as a root:
# yum downgrade graphviz-2.12-8.el5
# yum install yum-versionlock
# echo "graphviz-2.12-8.el5.i386" >>/etc/yum/pluginconf.d/versionlock.list
# echo "php-common-5.1.6-27.el5_5.3.i386" >>/etc/yum/pluginconf.d/versionlock.list

Then edit the file /etc/yum.repos.d/CentOS-Base.repo, by adding this line both under [base] and [updates]: exclude=php53*

Install NagVis following our documentation:
http://assets.nagios.com/downloads/nagi ... ith_XI.pdf

Before you try to access NagVis in your browser by: http://<yourserver>/nagvis, open your /etc/httpd/conf.d/nagvis.conf file, find the line that starts with AuthUserFile and change "nagios" to "nagioxi". It should look something like this: AuthUserFile /usr/local/nagiosxi/etc/htpasswd.users

After this, you can try logging in with your nagiosxi username and password.

When we come up with a better solution, you can apply it and then comment out (or delete) the "exclude=php53*" line in the /etc/yum.repos.d/CentOS-Base.repo.

Thank you very much for your answer. I'll be waiting for the final solution to this issue.

Our NagVis installation script has been updated. If you follow the steps in that document again it should work this time. Let us know if you have any more troubles!

Thanks. It seems to work like a charm.
