How to install Diamond on OpenBSD

Diamond is a Python daemon that collects system metrics and publishes them to various outputs. Here's how to install it on OpenBSD:

1. Install Python and pip:

   $ sudo pkg_add python3
   $ sudo -H python3 -m ensurepip
   

2. Install dependencies:

   $ sudo pkg_add py3-six
   $ sudo pkg_add py3-psutil
   $ sudo pkg_add py3-configobj
   $ sudo pkg_add git
   

3. Clone the Diamond repository:

   $ git clone https://github.com/python-diamond/Diamond.git
   

4. Install Diamond:

   $ cd Diamond
   $ sudo python setup.py install
   

5. Configure Diamond:

   Diamond's configuration file is located at /etc/diamond/diamond.conf. You can start with the default configuration file by copying it from the Diamond repository:

   $ sudo cp Diamond/conf/diamond.conf.example /etc/diamond/diamond.conf
   

   You can then edit /etc/diamond/diamond.conf to customize Diamond's config. Here are some examples:

   • To collect CPU usage, add the following to the [Collectors] section:

     [[CPUCollector]]
     

   • To collect memory usage, add the following to the [Collectors] section:

     [[MemoryCollector]]
     

   • To publish metrics to Graphite, add the following to the [Handlers] section:

     [[GraphiteHandler]]
     host = <graphite host>
     port = <graphite port>
     

6. Start Diamond:

   $ sudo service diamond start
   

   Diamond will now collect system metrics and publish them to the specified outputs.

Congratulations! You have successfully installed and configured Diamond on OpenBSD.
