 There are excellent Heap dump analysis tools like Eclipse MAT, Jprofiler, … These tools are handy when you want to debug/troubleshoot OutOfMemoryError. However, we HeapHero as following unique capabilities which aren’t available in those tools:  1. How much memory wasted?   HeapHero tells you how much memory your application is wasting because of inefficient programming practices by the developers. Today memory is wasted because of reasons like: a. Duplication of stringsb. overallocation, and underutilization of data structuresc. Boxed numbersd. Several more reasons. You can see HeapHereo reporting how much memory is wasted even in a vanilla pet clinic spring boot application. Other tools don’t provide this vital metric.  2. First cloud application for heap dump analysis  Today’s memory profiling tools need to be installed on your Desktop/Laptops. They can’t run on the cloud. HeapHero can run on a. Public cloud (AWS, Azure,..)b. Your private data centerc. Local machine Your entire organization can install one instance of HeapHero in a central server, and everyone in the organization can upload and analyze the heap dump from this one server.  3. CI/CD pipeline Integration  As part of CI/CD pipeline, several organizations do static code analysis using tools like coverity, vera code… . Using HeapHero, you can do runtime code analysis. HeapHeroprovides REST API. This API returns JSON response, which contains key metrics related to your application’s memory utilization. You can invoke this API from CI/CD pipeline and see whether your code quality is improving or regressing between each code commit.  4. Instant RCA in production  Debugging OutOfMemoryError in production is a tedious/challenging exercise. You can automate the end-end analysis of OutOfMemoryError using HeapHero. Say if your application’s memory consumption goes beyond certain limits or experience OutOfMemoryError, you can capture heap dumps and do heap dump analysis instantly using our REST API and generate instant root cause analysis report. Production troubleshooting tools like ycrash leverages HeapHero REST API to do this analysis for you.  5. Analyzing heap dumps from remote location  Heap dump files are large in size (several GB). To troubleshoot the heap dump, you have to transmit the heap dump file from your production server to your local machine. From your local machine, you have to upload the heap dump file to your tool. Sometimes heap dump might be stored/archived in remote server, AWS S3 storage,… In those circumstances, you will have to download the heap dump from that remote location and then once again upload it to the tool. HeapHero simplifies this process for you. You can pass the heap dump’s remote location URL as input to the HeapHero API or to web interface  directly. HeapHero will download the heap dump from this remote location to analyze for you.  6. Report Sharing & Team collaboration  Sharing Heap Dumps amongst team is a cumbersome process. Finding a proper location to store the heap dump file is the first challenge. The team member with whom you are sharing this report should have the heap dump analysis tool installed on his local machine. So that he can open the heap dump file with the tool you are sharing to see the analysis report. HeapHero simplifies this process. HeapHero gives you a hyperlink like this. This hyperlink can be embedded in your emails, JIRA, and circulated amongst your team. When your team member clicks on this hyperlink, he can see the entire heap dump analysis report on his browser. HeapHero also lets you export you heap dump as PDF file. This PDF file can also be circulated amongst your team members. 7. Analyze large size heap dumps  Several memory profilers are good at analyzing heap dumps of smaller size. But they struggle to analyze large size heap dumps. HeapHero is geared to analyze heap dumps easily. Author bioEvery single day, millions & millions of people in North America???bank, travel, and commerce???use the applications that Ram Lakshmanan has architected. Ram is an acclaimed speaker in major conferences on scalability, availability, and performance topics. Recently, he has founded a startup, which specializes in troubleshooting performance problems.
