Frequently Asked Questions

Why Resileo? I am currently using another APM solution. Why should I consider switching to Resileo?

The odds are that you are currently using one product for load testing, another for Synthetic monitoring and another for Real User monitoring and Application deep dive analytics. Only Resileo offers an integrated product that manages all your APM needs from one control panel and displays all the results on a customizable dashboard. Resileo is the only APM solution in the industry that offers Load testing, Synthetic User Monitoring (Resileo SUMTM), Real User Monitoring (Resileo RUMTM), Mobile User Monitoring (Resileo MUMTM) and Deep dive analytics (Resileo ADDTM) from one integrated platform.

Why is Resileo better?

Resileo is the only APM solution in the industry that offers Load testing, Synthetic User Monitoring (Resileo SUMTM), Real User Monitoring (Resileo RUMTM), Mobile User Monitoring (Resileo MUMTM) and Deep dive analytics (Resileo ADDTM) from one integrated platform. We collect and analyze data from each individual measurement and offer analytics based on all the measurements. Although other APM tools offer so called analytics, they fail to mention that they are not measuring everything needed to offer a complete APM. In other words, they can’t really analyze that they don’t measure, leaving a very significant gap in your analytics.

I am currently doing Real User Monitoring and deep dive Analytics. Why should I care about Synthetic user monitoring?

It’s the difference between being proactive vs. reactive. Synthetic User Monitoring is akin to preventative care vs. emergency care. With Real User monitoring, you have to wait for a real client to have a problem before you realize that there is a problem. Resileo SUMTM (Synthetic User Monitoring) allows you to be proactive and realize that there is a problem somewhere along the application delivery chain before your clients feel the pain. It offers a chance to significantly improve client satisfaction and improve user experience.

How can Resileo help with my new marketing initiative?

Resileo can help you maximize your marketing ROI by helping put the dollars in the right place. Using our load test, we can help you ensure that your web site can handle the additional expected traffic. By using Resileo SUMTM (Synthetic User Monitoring), you can ensure that your users or clients from a particular geography will have a good user experience. If you are in the process of opening new data centers, Resileo SUMTM can also help you determine what the user experience will be for each of the data center locations helping you invest in the right location.

My Apps are hosted on a public cloud. Do I need to worry about APM?

With the current cloud initiatives, it’s even more important to monitor your application delivery performance. It’s the audit that allows you to determine that your cloud-hosting provider is delivering the performance and uptime that they promised.

My cloud-hosting provider manages my apps and manages performance. Do I still need to worry about APM?

Most cloud hosting companies offer uptime and performance time guarantees. Resileo allows you to independently audit and ensure that the SLA’s are not being breached. It’s the difference between you knowing that something is about to go wrong in the application delivery chain or hearing about it from the hosting provider next day, after there was a problem or worse, reading about it in the paper.

Why is APM important to my business?

Study after study has shown that for every second past 4 seconds it takes for your content to load, you lose 10% of the visitors on your web site. This means that if your content loaded in 8 seconds, you have potentially lost 40% of the clients. These are clients that you spent money on to drive to your site. Resileo can help you be proactive in predicting these challenges and avoid performance issues.

I don’t have end users visiting my web site/applications. Do I need to think about APM?

Even if you don’t have end user customers on your web site, the odds are that like most companies in the 21st century, you are delivering content to your employees, partners or vendors. Your employees might be accessing your ERP or HR systems over the web; your partners might be accessing your systems on the web and so on. Every second an employee, partner or vendor waits for content to be delivered causes drops in productivity. Resileo can help you boost productivity by ensuring that the content is being delivered

How can Resileo help me increase my revenue and thus, the bottom line?

Like most companies, you are spending money to drive visitors to your web site and are working to convert visitors to paying clients. Resileo can help ensure that your site is performing at optimum levels to ensure that the money you spend on marketing and drive traffic to your web site is actually working by helping convert these visitors into customers. Resileo can help lower the abandoned sales that might occur due to poor application performance. If the content being delivered fails to meet the expected performance, these visitors will potentially leave your site and visit other sites with same content or product. In this case, you have paid to drive traffic and paying customers to your competition.

What is an agent?

An agent is a very small, non-intrusive, lightweight, executable file that you download and install on the server that you would like to monitor. The agent will monitor your server health and communicate with our analytics engine to support your monitoring requirements.
