Due to inefficient programming modern applications wastes 30% to 70% of memory. HeapHero is the industry's first tool to detect the amount of wasted memory. It reports what lines of source code originating the memory wastage and solutions to fix them.
Memory leak is a type of resource drain that occurs when an application allocates memory and does not release after finish using it. This allocated memory can not be used for any other purpose and it remains wasted. As a consequence, Java applications will exhibit one or more of these non-desirable behaviors: poor response time, long JVM pauses, application hang or even crash.
Android mobile applications can also suffer from memory leaks, which can be attributed to poor programming practices. Memory leaks in mobile apps bare direct consumer impact and dissatisfaction. Memory leak slows down the application's responsiveness, makes it hang or crashes the application entirely. It will leave an unpleasant and negative user experience.
One common indication of a memory problem is the java.lang.OutOfMemoryError. This error is typically thrown when there is insufficient space to create a new object in the Java heap. There are 8 flavors of OutOfMemoryError. Each flavor of OutOfMemoryError has different causes and solutions.
Sometimes the latest version of an application might be consuming more memory than the previous version. You need to analyze what are the large objects residing in the memory? Where is it being created? Where is it being held up? Answers to all these questions can be found in Heap Hero's Heap Analysis Report.
Wrong data structure choice, created but unused data structure, overallocated and underutilized data structure, suboptimal data type usage (i.e. using 'long' instead of 'int'), data duplication - all these can easily waste 30 - 70% of your memory. Heap Hero's intelligence report helps eliminate these memory hogs.
Heap Hero is the world's first and the only cloud-based heap dump analysis tool. Registration, download or installation is not required to use the tool. Just upload your application's heap dumps & review the beautiful reports instantly.
HPROF is a simple command line tool that captures CPU/Heap profiles to identify performance bottlenecks in applications. By default this tool writes the captured profiles to a file with '.hprof ' extension. HPROF file may contain CPU usage, heap allocation statistics, heap dump, thread stack traces and monitor states. It can be either in binary or text format. Heap Hero is a powerful tool to view and analyze HPROF files.
Heap Hero, a universal tool that will parse and analyze heaps dumps written in any language that runs on the JVM. It will convert Java, Scala, Jython, JRuby heap dumps to useful information to optimize your memory usage.
Heap Hero has built the industry's first, and only, REST API to analyze heap dumps. Stop manually uploading and analyzing heap dumps. Analyze heap dumps from all your JVMs and Android devices in a programmatic manner through Heap Hero's REST API.
Our award winning deep learning algorithms have the intelligence to detect memory leaks and isolate the objects that are causing the memory leaks. Save time spent on diagnosing memory leaks. It's all done automatically.
Heap Dump files consume a lot of disk space, making it very hard to share and collaborate with the team. Heap Hero provides shareable URL links to heap dump analysis reports, making it a breeze to share and collaborate heap dump analysis with your fellow engineers.
Analyzing heap dumps doesn't have to be tedious job. It can be fun, it can be 'wow'.
We have optimized hundreds of open source and enterprise applications. Take advantage of our battle fought experience. We can either come on-site or provide remote consulting services.
Our easy to understand, fun filled, on-site training programs is a preferred choice for several enterprises to transform their engineers in to performance experts.
Are you looking to port your application to AWS cloud? Are you following AWS best practices? Are you looking to lower your bills AWS? We are here to help you.
There are 7 options to capture heap dumps. jmap tool under <JAVA_HOME>\bin folder is an effective option. It can be invoked using command:
jmap -dump:format=b,file=<heap-dump-file-path> <process-id>
This article walks you through various options and steps to capture android heap dumps.
Of course. Here are sample heap dump analysis reports generated by Heap Hero:
a. Sample Report #1
b. Sample Report #2
We parse multiple heap dump formats. But still, we keep uncovering new formats of heap dumps. If you can email your heap dump to team@tier1app.com, we will enhance the tool to parse it.
Yes, the tool can parse binary and text format of heap dumps generated by both Java and Android platforms.
Yes, you can install this tool locally, so that you don't have to upload the dumps to our servers. Please see the pricing for this plan. You can register here to get a free 14-day trial of our products: GCeasy.io, fastThread.io, HeapHero.io.
