Rackspace Monitoring Agent
The monitoring agent is the first agent to use the infrastructure provided by virgo-base-agent
Installing The Agent
Make sure you have the required packages to build things on your system. The
Dockerfile will contain the development dependencies.
Please note, we provide binaries for many platforms. Check out the article here for instructions.
Otherwise, continue reading this section.
If you're on windows you may have to either install or find and add certain utilities to your path beforehand. These are:
- cmake - Downloadable from cmake gnu site
- nmake - Included in Visual studio/VC/bin but may need to be inserted into your path
- signtool - Included in Microsoft SDKs/windows/v7.1a/bin but may need to be inserted into your path
Get the source:
git clone https://github.com/virgo-agent-toolkit/rackspace-monitoring-agent
Go into the directory that you just created:
Now simply install the virgo client by running this last and final command:
After installing on unix systems, there is a new binary called
rackspace-monitoring-agent. To get the client running on your system please
follow the setup procedure as found
Host Info Runner
The agent has a built in host information runner (similar to OHAI).
rackspace-monitoring-agent -e hostinfo_runner -x [type]
The following hostinfo types currently exist:
CPU DATE DISK FILESYSTEM LOGIN MEMORY NETWORK PACKAGES PROCS SSHD SYSCTL SYSTEM WHO

Building for Rackspace Cloud Monitoring
Rackspace customers: Virgo is the open source project for the Rackspace Cloud Monitoring agent. Feel free to build your own copy from this source.
But! Please don't contact Rackspace Support about issues you encounter with your custom build.
The agent is versioned with a three digit dot seperated "semantic version" with the template being x.y.z. An example being e.g. 1.4.2. The rough meaning of each of these parts are:
major version numbers will change when we make a backwards incompatible change to the bundle format. Binaries can only run bundles with identical major version numbers. e.g. a binary of version 2.3.1 can only run bundles starting with 2.
minor version numbers will change when we make backwards compatible changes to the bundle format. Binaries can only run bundles with minor versions that are greater than or equal to the bundle version. e.g. a binary of version 2.3.1 can run a 2.3.4 bundle but not a 2.2.1 bundle.
patch version numbers will change everytime a new bundle is released. It has no semantic meaning to the versioning.
Virgo supplies infrastructure for running tests. Calling make test will launch Virgo with command line flags set to feed it the testing bundle and with the -e flag set to tests.
You can also run an individual test module:
TEST_MODULE=net make test
