Nagios, Octave and SilverStripe in OpenSolaris
By MandyWaite on Oct 28, 2009
Several interesting packages were published to the OpenSolaris /contrib repository yesterday. They include Octave, SilverStripe and the 3 packages that make up Nagios.
Nagios is a leading Open Source infrastructure monitoring tool that can monitor networks, hosts and even services, in fact it can monitor pretty much anything and it being Open Source it's fairly straightforward to add your own plugins. The main Nagios package is simply named nagios and delivers version 3.0.6 currently. In addition there is the nagios-plugins package which you'll install on systems that you want to monitor. A third package is nrpe (Nagios Remote Plugin Executor), which allows a centralised deployment of Nagios to execute and monitor plugins on other systems.
Octave is a GNU project, it's a high level language and runtime whose main use is for numerical computations. It's mainly command line driven, but can hook up with the likes of gnuplot in order to present graphs and other visual forms of mathematical data. I've tested it and it looks like it could be really useful for someone say, studying for a maths degree... like me for instance :o)
SilverStripe is a popular Open Source Content Management System, it's one of a number of such applications that OpenSolaris users have been clamouring for. Interestingly we did have some problems getting it to play nicely with MySQL 5.1 on OpenSolaris. When you are setting up the MySQL database prior to configuring SilverStripe modify the MySQL SMF service as follows:
svccfg -s mysql:version_51 setprop mysql/enable_64bit=true svcadm refresh mysql:version_51 svcadm restart mysql:version_51
You'll either need to do this as root or as a user with the root role. These changes cause MySQL 5.1 to run in 64-bit mode.
You can install any of these packages either using the pkg command or via the package manager, you can even just go to the /contrib repository's catalog page and click on the 'install' link for the package(s) that you want to install.
To set up /contrib as a valid publisher for use with the package manager or the pkg command do the following as a user with the root role (or Software Installation profile):
pfexec pkg set-publisher -O http://pkg.opensolaris.org/contrib contrib
Or you can add /contrib via the package manager through the File -> Manage Repositories pull down. If installing from the "install" link at http://pkg.opensolaris.org/contrib/en/catalog.shtml the package manager will automatically add /contrib to the list of publishers.
To install packages using pkg, do the following:
pfexec pkg refresh
pfexec pkg install <package name>
These packages are great additions to the growing list of packages available via the /contrib repository. If you would like to contribute a package to /contrib visit the SourceJuicer page on OpenSolaris.org. If you'd rather not get involved in submitting spec files to SourceJuicer but would like to see a package in OpenSolaris, drop us an email at firstname.lastname@example.org.
