With HTML5 we have made significant improvements in the charting section which offers our customers a greater deal of functionality in allowing more flexibility in how they interact with the product combined with a reduction in the time spent identifying potential Array performance problems.
This release is significantly different from the previous in terms of layout and usage so I wanted to touch on certain key elements before I delved into some of the potential use cases.
You have the ability to name the chart if you wish but it’s optional, in the timeframe drop down you have the following options:
Realtime – the last hour at 30 second granularity for up to 5 SG’s at a time on 1 array covering certain KPI’s or run a trace at the system level.
Diagnostic – 1, 2, 4, 8, 12, 24 hours or customizable allowing you to focus on a certain timeframe such as 03:15 – 03:45 a.m. last night.
Historical – last 24 hours, last week, last month, last 6 months, last 12 months or customizable allowing you to focus on a certain timeframe such as 12:00 – 05:00 on the 24th of last month.
In Objects you have the ability to select from Array, Storage & Hosts, Directors & Ports, Storage Resources, Data Protection and System internals where by you can focus on the specific category you need to target.
If you notice the radio button highlighted in red we have given you the ability to toggle between average and max values here. Also in the metric list section you can choose just to display KPI Metrics or all metrics.
Additionally for the icons below the default tab I wanted to outline and explain what their function is:
- Save as Template – allows you to save it as a template if you need to focus on certain KPI Metrics for a particular object like metadata usage on an array.
- Save as PDF – Charts – This allows you to save a chart and send it to a colleague in a visual format if you want to illustrate a certain pattern like capacity growth in a the last month.
- Save as PDF – Charts & Data – like above this gives you back the visual charts and also the figures behind that.
- Copy Charts to a Tab – allows you to copy charts over to a different tab while retaining the originals in the current tab
- Move Charts to a Tab – allows you to move charts completely over to a different tab
In the previous version of the software the navigation was along the top of the screen but we have changed this to a left hand side navigation view so customers can more easily interact with the product. In this example I have created a chart called PerfIssue03/20 whereby I have selected the timeframe of the last 4 hours for the array 0647 and selected the KPI’s % reads and % Writes and drew my chart accordingly.
As a potential use case let’s say we were focusing on a potential issue from last night and we began by checking the last 4 hours and we found nothing of note so we decided to expand our scope. To do this we copied out chart with the pencil icon and we changed the time frame to the last 8 hours and added 2 additional metrics called BE IO’s Per Sec and BE READ Req’s Per Sec and then draw a new chart.
Some of this functionality was in the previous product but we have reduced the input required from the end user and allowed them to merely copy a chart and edit it if required.
Additionally we have allowed you to add more tabs in the same way you do with a web browser so if you were comparing performance over a couple of days similar to what you see in the screenshot you can label charts by day and group accordingly.
