Report Scheduler

Inspiration

• System admin David's boss needs to know how cpu utilization is going on Monday mornings for a report to administrators
• David has to go through, find all necessary charts, find the right dates, screen shot capture... too much work.
  
• David wishes Ambari had a way to automatically create a nice summary report about the metrics he cares about.

What it does

Report Scheduler

• Widget to create a summary report instance
• Ambari Scheduler will collect requested information at interval set by user

• Ambari will create a summary report html which creates a comprehensive summary of cluster performance based on user's request

• Currently no way to schedule reports to be created -Need to add an option to Manage/Create summary reports in Dashboard of Component

How I built it

• New Action in the summary box of Dashboard components (ex. HDFS, Hbase, Yarn) /ambari/ambari-webapp/views/main/service/info/summary.js
• New Widget Modal for Report Scheduler

• Consistent with Ambari design

• Rest Calls --POST to create a report scheduler instance (which will collect data and generate HTML files), GET to display report schedulers --Use existing metrics API's

• Database Changes --Table to store the report schedules -HTML Report Generator --Given JSON FILE we generate HTML Files --Charts/Graphs with requested information over time --Save file as “.html”

• Scheduler --ExecutionSchedulerManager --Cron job will take in start and end date & time

Challenges I ran into

-- Time to implement everything!

Accomplishments that I'm proud of

-- Hopefully making system admin's life easier

What I learned

-- There is so much we can do and add to Ambari

What's next for Report Scheduler

-- More customizations to the widget -- Add emails, add more thresholds -- Alert update suggestions/analytics based on history of alerts seen -- More interactive charts to understand how alerts that popped up relate to the charts
