Software Engineering Accomplishments

Coding provides Keith with a creative outlet for his many ideas. It also helps him understand how software is built and operates. Keith has worked on many 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 Keith is the 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.

Patents

Keith does not believe in software patents and sees much more value in contributing to open source. Nevertheless he is proud of his accomplishments.

  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.
