Re: [Nagios-users] Integrating nagvis

Also be sure to verify that your dbprefix is set correctly in the 
etc/config.php.ini file for nagvis.

This is easily overlooked.

Easy.

Edit the index.html on this line:

I personally have the main page set to the tactical overview.

Re: [Nagios-users] Running Nagios on Linux

[Chris Moody]

First, I would start by installing the Nagios suite on Solaris.
[ http://www.nagios.org/docs/ ]

Then, once you have the software installed, copy over your configuration 
  file(s) and start the daemon.

Re: [Nagios-users] Read-only access to Nagios

If all you want is view only... set the following value:

cgi.cfg:
use_authentication=0

This will cause the maps/dashboard to be visible...but nobody can modify 
anything.

Re: [Nagios-users] TWO instances of Nagios on one server - possible?

[Chris Moody]

Check out my vhost script on nagios-exchange.

This is completely possible and works GREAT.  I currently have 10+ 
"vhosts" running on a server.

I have some 0.1rev code on the nagios-exchange site...and will be adding 
code for the 2.x train of Nagios very soon. (I have it working, but want 
to tidy it a bit more).

My build script can setup everything but the "instance specific" details 
of the host files.

Re: [Nagios-users] Several map views of Nagios

[Chris Moody]

The statusmap.cgi does not re-draw the map in regards to screen 
coordinates when hiding groups.  Your maps will remain "cluttered" even 
though you can filter what's even displayed.  This is a known limitation 
of the statusmap.cgi map.

I've had (very minor) success is setting the scale larger.

I have yet to find a perfect solution.  I'm in a situation where I have 
several thousand "nodes" to watch.

My interim solution has been to create multiple nagios instances with 
apache vhosts.  This way I can group systems logically and represent 
them in a cleaner fashion.  I have 0.1-rev code available via 
nagios-exchange to build the different vhosts. (I'm hoping to have a 
newer build available soon (with support for 2.x train of Nagios).)

Were my C skillz better, I'd try to take on a building a more adaptive 
drawing algo...

[Nagios-users] Limiting Views of Hosts - over 3k hosts

[Chris Moody]

On a similar note(but starting a new thread), does anyone have
experience (with a modified cgi or whatnot) of removing the non-visible
hosts from view and re-drawing the statumap to only display the visible
hosts...but at the appropriate scale.

(perhaps I should explain in more detail)

I'm stuck in a situation where I need to display over 3000 hosts, but
broken up into 4 groups.  The trouble is that with that many systems,
even if I "pad" the statusmap with parents to expand the diameter of the
map, there are too many systems and they overlap.  Even when I split
them into groups and only have group views, the main map doesn't exclude
the non-visable hosts when it draws...so the systems still overlap, but
with blank space in between the clusters.

I have modified the CGI to increase the default diameter of the map, but
it's still a bit crowded.  I'm open to whatever creative means (groups
or not) to get the map to scale appropriately.  I need the hosts
displayed for visual dependency tracking.

I can provide screenshots if necessary.

Anyone have any ideas.

Cheers,
-Chris

Yes. Set them up as a contact and only include them on the hosts you

define host{

host_name   acsdb
alias   acsdb
address 192.168.40.40
contact_groups  sys-admins,localonline

'sys-admins' is setup for everything. 'localonline' only gets a subset 
of hosts that those folks are concerned with.

Hi Everyone,

I am wondering if there is a way to allow people who login to only
view a specific set of hosts.  This way I can have one Nagios system
checking multiple clients but the clients can only see thier hosts
and thier host results.  I am running the newest version 2.0b6.

Thanks in advance.

Re: [Nagios-users] Re: Multi User NagiOS

[Chris Moody]

Since it sounds like you are also looking for a way to prevent a user 
from adding/deleting hosts/services/etc from another user's 
listings...you can check out my nagios Vhost script on nagiosexchange.


I have a situation where I run seperate nagios processes for each group. 
 This allows the users in the group to modify their instance of nagios 
to their heart's content...without even touching the other processes 
and/or configs.


It is quite trivial to chroot users to the nagios directory of their 
group when they login to the server to modify their setup.


If you -need- this kind of functionality as well, I'd recommend the 
Vhost setup.  If you only need to separate the _views_...then the nagios 
auth configs are the perfect solution and don't require any extra processes.


Cheers,
-Chris
