Previously, the cumin package had a dependency on the dejavu-lgc-sans-fonts package, which is only available through an optional Red Hat Network channel. As a consequence, the Cumin web console could not be installed on Red Hat Enterprise Linux 6 using only the non-optional Red Hat Network channels. With this update, the dependency has been changed to the liberation-sans-fonts package and Cumin now installs correctly in the described scenario.

Description

I vote for adding this to installation manual. Without an advice that some extra channels ("RHEL Server High Availability" and "RHEL Server Optional") are required, I was stuck with a simple installation of MRG-M. The manual is too vague and general.
oops, please ignore comment 1, I posted it to wrong wrong tab in firefox..:( See bug 694457 for why dejavu-lgc-fonts is a dep on EL6. Origin of this is cairo needs a font (fontconfig based) installed otherwise the png graphic generation will fail. Reproduce by installing cumin and yum removing all installed fonts (including rpm -e --nodeps dejavu...). Once the system is purged of fonts, restart cumin and, with a flash-disabled browser, navigate to a screen with a graph. For instance, Inventory->a system. In place of the graph, "stats" will be displayed. Going directly to the graphic link (copy image location, open new window to location), will display something along the lines of - Traceback (most recent call last): File "/usr/share/cumin/python/wooly/wsgiserver/__init__.py", line 1250, in communicate req.respond() File "/usr/share/cumin/python/wooly/wsgiserver/__init__.py", line 663, in respond self._respond() File "/usr/share/cumin/python/wooly/wsgiserver/__init__.py", line 669, in _respond response = self.wsgi_app(env, self.start_response) File "/usr/share/cumin/python/wooly/server.py", line 83, in service_request status, headers, content = self.service_page_request(page, env) File "/usr/share/cumin/python/wooly/server.py", line 130, in service_page_request content = page.service_error(session) File "/usr/share/cumin/python/wooly/__init__.py", line 484, in service_error return self.render(session) File "/usr/share/cumin/python/wooly/__init__.py", line 314, in render string = self.do_render(session, *args) File "/usr/share/cumin/python/cumin/stat.py", line 584, in do_render chart.plot_x_axis(x_intervals, x_step) File "/usr/share/cumin/python/cumin/charts.py", line 345, in plot_x_axis cr.show_text(text) MemoryError The cairo code in cumin does not specifically select a font for use in drawing graphs, so pretty much any font installed will work. dejavu-lgc-sans-fonts would work, except it is part of the EL6 -optional package set. I tested liberation-fonts on EL5 and liberation-sans-fonts on EL6 with success. No change needed on EL5. Change dejavu-lgc-sans-fonts to liberation-sans-fonts on EL6. Verification should make sure that no dependencies are coming from the -optional channel. Changed the dependency for el6 in cumin.spec to liberation-sans-fonts. Reproduction:
RHEL5
# yum install cumin
OK
# rpm -q cumin
cumin-0.1.4916-1.el5
# yum deplist $(rpm -q cumin)
dependency: dejavu-lgc-fonts
provider: dejavu-lgc-fonts.noarch 2.10-1

x86_64# yum list available --showduplicates dejavu-lgc-fonts
dejavu-lgc-fonts.noarch 2.10-1 rhel-x86_64-server-5
RHEL6
i386# yum install cumin
Error: Package: cumin-0.1.4916-1.el6.noarch (rhel-i386-server-6-mrg-management-2)

# yum deplist cumin

Unsatisfied dependency

Verification:
RHEL5

# rpm -q cumin

Verify graphs:
Restart cumin and, with a flash-disabled browser, navigate to a screen with a graph. For
instance, Inventory->a system. In place of the graph, "stats" isn't
displayed - there is a proper PNG graph. Going directly to the graphic link (copy image location, open new window to location), verify image is PNG, image is displayed properly.
