Go with NX-API

I’ve been working on a project to collect data from Cisco Nexus switches.  I first tackled making SNMP calls to collect counter statistics but then I thought, why not try it with the NX-API that came with the Nexus 9ks? The documentation for the APIs I hoped would be better, but the samples on github […]

Continuous Delivery of a Simple Web Application Tutorial – Part 4

In Part 1 we discussed the architecture of what we’re trying to build. In Part 2 we created our development server with Ansible. In Part 3 we finished off Ansible with creating our Load Balancers and WebServers and setup Git to check everything in. In this last part, we’re going to configure Jenkins to use all of these components […]

I’m a big fan of Ansible […]

VMware is the AOL of the private cloud

This week at VMware Partner Exchange there was a nice announcement of VMware Integrated OpenStack or VIO.  VIO attempts to do what most of the developers of OpenStack have failed to do:  Make OpenStack easy to deploy and manage.  (It’s not, anybody who tells you different is trying to sell you something).  The sound bite […]

UCS Performance Manager

Today I deployed UCS Performance Manager.  At first glance It appears to be a customized version of Zenoss with all the UCS goodies built into it so you can graph and trend over time the different metrics made available by the UCS API.  Therefore there is no agents that need to be installed.  I’m a […]
