- Does anyone know of or have a product that perfroms stress / load testing on a hp-ux 11.11 server. I want to test the cpu, memory, I/O and disks on the system thanks John.
- Test faster LoadRunner Professional provides IDE to integrate with development environments; enabling developers to run unit tests using the LoadRunner Professional engine. Developers can create LoadRunner Professional scripts directly within the IDE, enabling performance testing earlier in the application lifecycle.
- Developer tools Database SQLQueryStress is a simple, lightweight performance testing tool, designed to load test individual queries. It includes support for randomization of input parameters in order to test cache repeatability, and includes basic capabilities for reporting on consumed server resources.
HP Smart Array controllers don't fail often. Typically failure is sudden and not something that degrades over time. Either way, you can run offline diagnostics on the array by booting the HP SmartStart DVDincluded with the server and running the HP Array Diagnostics Utility (ADU). You didn't indicate the model or generation of your server or the RAID controller (those things are helpful), but the linked DVD image should cover most recent HP systems. HP PC Hardware Diagnostics Windows is a Windows-based utility that allows you to run diagnostic tests to determine if the computer hardware is functioning properly. The tool runs within the Windows operating system in order to diagnose hardware failures.
Even the most novice among website owners has at some point or other tested their website performance. However, most of these tests normally focus on loading speed or user experience indices.
But what about load testing?
Although most websites are prone to traffic levels that are usually quite regular, there may be occasions when some sites will have to deal with heavy loads. Examples of these include online stores, or even some government websites.
If your website gets an unexpected spike in the number of visitors over a short period, how well are you equipped to handle it?
Understanding Load Testing
What is load testing?
Load testing is bench-marking a website to see how it performs under various loads.
For example, a test may simulate an increasing number of concurrent visitors landing on your site. It will also record how your site handles them and records them for your reference.
What types of “load” are tested?
Depending on the tool you choose to load test your site with, each may come with different features. The most basic will simply involve simulating an ever increasing load and halting when your site crashes.
Other tools may be capable of generating a simulated load that mimics different user behaviour, such as performing queries, changing pages, or loading other functions. Some may even be able to map out logical flows for each individual scenario.
Load Testing Tools to Consider
Depending on their complexity, some load testing tools can be quite expensive. However, there are cheaper options in the market and some are even free for use. I’ve included a mixture of these below for your reference, including a couple of open source options.
1. Loadview by Dotcom Monitor
Price: From $199/mo, free trial available
Loadview is one of the more complete solutions available in the market and today is based on a cloud service model. This means that whatever type of simulation you need from them, you only pay for the service – there is zero investment in hardware or anything else.
Feature wise, Loadview offers a very complex solution that can include anything from straight up HTTP load tests to a sophisticated mix of your choice. It is able to simulate dynamic variables and even geo-location diversity in its tests.
Features
- Post-firewall tests
- Handles dynamic variables
- Detailed waterfall charts
- Load test curves
2. K6 Cloud (formerly Load Impact)
Price: From $49/mo
K6 is a cloud-based, open source load testing tool that’s provided as a service. One of the things that makes this tool interesting is that it is priced on a variable-use model which means that the cost of entry can be relatively low depending on your needs. It is, however, mainly developer-centric.
Aside from load testing, K6 also offers performance monitoring. Its load testing side is focused on high loads and can handle various modes such as spikes, stress testing, and endurance runs.
*K6 does not run in browsers nor does it run in NodeJS
Features
- Developer-friendly APIs.
- Scripting in JavaScript
- Performance monitoring
3. Load Ninja
Website: https://www.microfocus.com/ Website: https://loader.io/ Features Price: From $0 Gatling comes in two flavors, Open Source or Enterprise. The former lets you load-test as an integration with your own development pipeline. It includes both a web recorder and report generator with the plan. The Enterprise version has on-premise deployments or alternatively, you can opt for a Cloud version based on Amazon Web Services (AWS). Although both of these versions are feature-packed, the Enterprise version supports a few extras that don’t come with Open Source. For example, it has a more usable management interface and supports a wider range of integrations. Features Price: From $0 Grinder is open sourced all the way and is probably the only truly free option on this list. However, it has to be run locally in your own development environment and needs a few extra such as Java in order to work. However, being open source it has been adopted widely and developers have come up with a plentiful number of plugins which vastly extend it in terms of both use-ability and functionality. Still, unless you’re a developer or so oriented, The Grinder might be a bit of a handful for you to use. Features If you’ve had a look at most of the tools available, you will probably have noticed that many of them offer either trial accounts or some form of limited free version. This makes them readily available for use for a wide audience. Most website owners need to be concerned about hosting performance since it affects far more than simply user experience. For many business owners, the availability of your website is also a matter of brand reputation. Sites which are growing need to be especially cautious of availability and scalability of the resources used to hosting your website. In most cases a high percentage of user response time is spent on the surface of your site. However, as sites grow in traffic volume this might change. More traffic usually means a disproportionate growth in backend processing and your system will struggle as that spikes. Much will depend on variables unique to your site development, so it isn’t possible to give you a solid number of visitors at which point this will happen. To realistically see how your site performance you need load testing to be done. Exactly when to do it is debatable, but my advice would be to plan ahead and test early. As the very name implies, your core function should be the basic of how your site performs under loads. This will let you observe a number of things such as: When I mentioned how different sites may react differently based on their architecture, that was a signal meant for you to understand that not all sites fail in the same way as well. Some database-intensive sites might fail on that point, while others may suffer IO failures based on server connection loads. Because of this, you need to be prepared to set up a variety of tests to understand how your site and server will cope under various scenarios. Based on those, keep a close eye on a few key metrics such as your server response time, the number of errors cropping up, and what areas those faults may lie in. Generating complex scripts and runs along with the accompanying logic can be difficult. I suggest that you approach load testing incrementally. Start with a brute force test that will simply test your site under a continuously increasing stream of traffic. As you gain experience, add on other elements such as variable behaviour, developing your scripts and logic over time. When it comes to load testing, starting with the basics is better than not getting started at all. If you’re a beginner to all of this, do try to do your testing on an alternate mirror or offline where possible – avoid load testing a live site if you can! If you’re just starting out now, make sure to create a record of your tests. Performance testing is a journey that should accompany the development of your site as it grows. The process can be tiring but remember, not having a record can make future assessments much more difficult for you.6. Gatling
