Background

I have over 20 years of enterprise IT experience. Have a strong software engineering background but also worked on infrastructure side, as a Linux systems and storage administrator. Worked for several high-profile companies such as Intuit, NetApp and Red Hat, both the USA and Europe. Through my career, I focused a lot of time around application integration and built distinct expertise in this area. Currently my focus is to help large enterprise organizations move toward containerization and building next-gen platforms. Opinions expressed in this blog are my own and do not necessarily reflect that of the company I work for.

Software Engineering Accomplishments

Coding provides a creative outlet for many of my ideas. It also helps to understand how software is built and operates. I have worked on several software engineering projects and some notable ones are mentioned below.

  • Integra – Provider based automation framework that enables IT teams to automate anything without creating technical debt. Integra is simple to understand and easy to use. It is truly a next-gen automation platform.
  • NetApp Snap Creator Framework – Snapshot based backup framework integrating applications with NetApp snapshot technology. Snap Creator is a backup product offered by NetApp and I am proudly it’s inventor.
  • Perfstat – Systems monitoring tool fashioned after another monitoring tool from 90s called Big Brother.
  • Snap2cloud – A framework for backing up storage snapshots to the cloud. Currently it implements NetApp to Amazon S3 but it could be extended to other storage vendors and cloud providers.

  2. Hi Keith.

    I try to implement the Autoscaling using with Ceilometer. I am able to create stack with heat template and I stree the CPU untilization morethan 90% . but still scaling is not happening.
    Also I see one issue Ceilometer alarm state is “insufficient data”

    [root@icmcs ceilometer]# ceilometer alarm-list
    +————————————–+————————————————-+——————-+———-+———+————+—————————————————————–+——————+
    | Alarm ID | Name | State | Severity | Enabled | Continuous | Alarm condition | Time constraints |
    +————————————–+————————————————-+——————-+———-+———+————+————————————————–
    | cacbac69-14eb-49c1-b1b1-042f8e0d3e52 | demo-autoscaling1-cpu_alarm_low-imzkpfqywqvn | insufficient data | low | True | True | cpu-util 50.0 during 1 x 50s | None |
    +————————————–+————————————————-+——————-+———-+———+————+————————————————–

    Ceilometer cpu_util alos not capturing.
    [root@icmcs ceilometer]# ceilometer statistics -m cpu_util
    +——–+————–+————+—–+—–+—–+—–+——-+———-+—————-+————–+
    | Period | Period Start | Period End | Max | Min | Avg | Sum | Count | Duration | Duration Start | Duration End |
    +——–+————–+————+—–+—–+—–+—–+——-+———-+—————-+————–+

    I appreciate help on this. thanks.
