Time series view of application performance metrics
This post builds off a previous post on the evolution of a second order metric, using the metric developed there as a basis for more advanced visualizations illustrating interactions between multiple ... Read MoreTime series analysis of workload isolation strategies
By now you have figured out that I really like time series plots of transactional data with log scale latencies as a visual representation of workloads. Taking this a step further, we can overlay colo... Read MoreTroubleshooting system performance with time series scatter plots
The use of time series scatter plots can provide far more insight into system performance when compared to using typical average latencies and cumulative throughput rates. These scatter plots a... Read MoreStack metrics for analyzing system performance
Stack over lays of time series data System performance testing relies (or should rely) on the aggregation of large amounts of data from a variety of sources within the supporting infrastructure. It... Read MoreComparing software release performance data
One challenge we face in summarizing end of release performance findings is how do you effectively illustrate release to release performance in a concise visual manner? One method I have been experime... Read MoreVisualizing DB2 buffer pool characteristics
This plot is a time series representation of the use of micro plots to illustrate the sizing decisions DB2’s memory manager is making for sizing multiple buffer pools (left series of plots, x-ax... Read MoreVisualizing experimental output trends over time
I’ve been working with startups in various states of product maturity to establish sound scientific methods for characterizing the application workloads. Most of my process recommendations focus... Read MoreBuilding a better gantt chart
I’ve been managing projects for well over 10 years, and the biggest obstacle that I encounter is communicating project status quickly and efficiently with a project team. We have lots of tools a... Read MoreVisualizing performance coverage
Regular performance testing of software releases yields a tremendous volume of comparative data that can be plotted to illustrate many trends in release over release performance and coverage. Take t... Read MoreEvolution of a second-order performance metric
As with any application that is undergoing a performance profiling effort, you start with standard instrumentation pulling data from the supporting infrastructure stack and from metrics specific to th... Read More- 2 of 2
