Alerting capabilities have enabled timely escalation and resolution of issues

In AlertSite, I was monitoring the kiosks and servers for JetBlue Airlines. The servers would trigger alerts if there were any outages or issues with any of the kiosks, servers, or the ticketing tool. I monitored these alerts and escalated them to the concerned team to rectify them at the earliest…

Solution simplifies web service testing with impressive speed and accessibility

It is very easy for me to use and I highly prefer it compared to SoapUI and other products for performing its job. It is more handy and faster. It has impacted us very nicely. Postman is used for free by us. I'm not sure if there might be a paid version for multiple users. It is a very good product used for development. It is easy to install, as well as to learn, particularly for new users, even if they are not developers. I taught my business analyst to use it. I just showed them once, and it was easy for them to understand. For example, I gave them the URL and request format and asked them to test independently. They were able to use it on their own and do their testing as well. It was a good experience, especially for generally smart people, like those we usually hire in our company. It is pretty easy to explain, and learning it is not complex.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"I highly recommend AlertSite to other users."

"The alerting capabilities of AlertSite were really helpful."

"I found multiple features in AlertSite that I like. One is data monitoring history, for example, a history of the blackouts and the data. Sometimes, there's a glitch in the application that AlertSite can capture, and the tool notifies you about that glitch. It also identifies issues that could happen in the future. AlertSite is also a fast tool that you can use to monitor on-premise servers, internal applications, and even global applications. The data is available on a single UI in AlertSite, so there's no need to monitor and click on different applications or URLs. I also love that the tool is quite user-friendly, apart from being fast."

"The alerting capabilities were really helpful."

"If there are any issues, it triggers an alert within 30 seconds. When it triggers the alert, we go ahead and check it immediately. The alert is triggered on a real-time basis."

"This solution has numerous advantages. It's extremely simple to configure. Either digital monitors or single-URL monitors are simple to configure and build."

"There are custom reports available along with the inbuilt reports."

"The best feature of AlertSite is that it shows you a visual graph and also sends you notifications about errors, so you get immediate notifications about errors which means that your support team can start taking steps and more quickly make sure the site is up and that customer experience isn't interrupted in terms of using your system and your products. AlertSite is a very good tool. It's user-friendly, and you can see everything on the dashboard. Configuring it is also easy."

"With Postman you can do automation. Automation has increased efficiency by more than 30% or 40%. Because the speed has increased, it's also possible for us to do in-sprint automation testing."

"Postman is one of the easiest tools; I have not seen anybody complaining because it's just one Google search away."

"It's easy to see different versions of responses."

"Postman helps us to automate the API testing in the team."

"The interface and the different types of API methods you can use are the most valuable aspects of this solution."

"The solution has helped us very well in testing endpoint URLs."

"The initial setup is simple."

"It allowed us to understand the working and performance of the APIs."

Cons

"What needs improvement in AlertSite is the documentation, particularly the lack of documentation. If there's a specific activity you want to do, you can't even find information on how to do it, so you have to contact the AlertSite support team to assist you, and only then would the issue be resolved. At the moment, it's not easy to find or get full documentation on how to deal with different issues. You always have to go back to AlertSite support and get help. The documentation for AlertSite could be improved and it's what I'd like to see in the next release of the tool because at the moment, the documentation isn't complete, so you'll have to contact support, but contacting support isn't an issue because the team responds to you quickly."

"One area that needs improvement in AlertSite is the slow UI. I'm using the classic UI because it's quite user-friendly, or in human-readable format, but it's a little slow. It takes time to load all the monitors, so if that could be sped up, that would be helpful. The AlertSite support team also needs improvement in terms of availability. Most of the agents in the team aren't available 24 x 7, so if there's something you need to discuss, you need to tell the support team ahead of time to schedule it. Multiple times, when a case comes up during weekends or whenever my team is doing an update, support needs improvement, availability-wise. I use AlertSite for synthetic monitoring, so whatever is available right now is okay, but if I want to request a new feature on a website, currently, the UI refreshes automatically. I would like to have the option on AlertSite to configure that manually. The UI auto-updates every few minutes, so if I can control that manually, that would be helpful."

"I would like the ability to get more data points with regard to some of the unique requirements that we have."

"Additionally, support from AlertSite is not at an enterprise level since it is not offered 24/7."

"AlertSite sometimes triggers false alerts or fake alerts, which needs to be rectified. When we see an alert and go ahead and run certain tests on it, the test always passes. However, on the main screen, it shows up as critical. Therefore, the false alert needs to be fixed."

"I could use a few changes to the user interface."

"It is not compatible with all of the product platforms that we use."

"One area that could be better is collection management."

"There are some limitations regarding large result sets in Postman. When dealing with several hundred records, accessing all the information can be challenging."

"We do the implementation of Postman and give support. We had to use two engineers for the implementation, one senior and one junior for the process."

"There are definitely features that could be improved; for example, if you derive it from Ready API, maybe Postman can be a good contender and replicate some features such as more scripting and control over API calls."

"I would like to see improvements in the maintenance of the scripts and their collections. It is really painful that the user cannot drag and drop. It was also painful to create the standard suite of operations for the product. I am not sure if this is improved in the tool’s latest versions. The maintenance of the complex scenarios prompted us to use the solution only for unit testing. In the future, we may switch to the k6 framework."

"An area that needs some improvement would be to allow multiple windows with different collections to be open at the same time."

"The management of endpoints' headers sometimes conflicts with APIs that require information in the body, leading to difficulties."

"I have display issues in my Windows that need to be fixed."

Pricing and Cost Advice

"My company pays to use AlertSite, but I'm unsure of the exact costs because it depends on how many monitors you have."

"The cost is high."

"We purchased the license once and had the option of selecting the number of user licenses."

"The solution has a licensing fee which might be prohibitive."

"I use the tool's free version."

"We use the open-source version. They introduced a new licensing model where your company must subscribe to their services if you're using it for business purposes. However, I think they charge too much if you're only using the basic features. It limits what your organization can do if you're not a paying customer."

"It is free."

"The solution has moderate pricing."

"The solution is open-source and free."

"We are using the free version that is available."

"This tool is open-source and free to download and use."
