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…

Useful log aggregation and management with helpful metrics aggregation
Datadog provides us value in three major ways: First, Datadog provides best-in-class functionality in many, if not all, of the products to which we subscribe (infrastructure, APM, log management, serverless, synthetics, real user monitoring, DB monitoring). In my experience with other tools that provide similar functionality, Datadog provides the largest feature set with the most flexibility and the best performance. Second, Datadog allows us to access all of those services in one place. Having to learn and manage only one tool for all of those purposes is a major benefit. Third, Datadog provides significant connectivity between those services so that we can view, summarize, organize, translate and correlate our data with maximum effect. Not needing to manually integrate them to draw lines between those pieces of information is a huge time savings for us.

Quotes from Members

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

Pros

"This solution has numerous advantages. It's extremely simple to configure. Either digital monitors or single-URL monitors are simple to configure and build."
"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 of AlertSite were really helpful."
"The alerting capabilities were really helpful."
"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."
"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."
"There are custom reports available along with the inbuilt reports."
"The visibility that it provides is valuable. It is helping in being proactive around incident management. It is helping us to be able to get more visibility into our customers' applications so that we can assist them at the application layer. We also provide them the infrastructure from an AWS standpoint. We are able to make sure that our customers are aware of certain critical things around the analytical piece of either the network or the application. We're able to call customers before they even know about the issue. From there, we can start putting together some change management processes and help them a bit."
"Its integration definitely stands out. It provides seamless monitoring of all our systems, services, apps, and whatever else we secure and monitor. Visualizations have become simpler with dashboards. We are getting visibility into systems, services, and apps stack through a single pane of glass, which is good. We are able to put logs in context."
"We've been able to glean from the monitors what servers are down, and can alert the team in Slack."
"The RUM solution has improved our ability to triage faster and hand more capabilities to our customer support."
"It has provided visibility with ease of implementation and allowed multiple teams to quickly onboard it."
"Dashboards are the most valuable."
"We have way more observability than what we had before - on the application and the overall system."
"We integrate our application logs. It is great to be able to tie our metrics and our traces together."
 

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."
"I would like the ability to get more data points with regard to some of the unique requirements that we have."
"I could use a few changes to the user interface."
"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."
"It is not compatible with all of the product platforms that we use."
"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."
"There is occasional UI slowness and bugs."
"The way data is represented can be limiting. When I first tried it out a long time ago, you could graph a metric and another metric, and they'd overlay, but you couldn't take the ratio between the two."
"The cost is pretty high."
"A big problem with Datadog is the billing. They need to make the billing more user-friendly."
"Some of the interface is still confusing to use."
"Once Datadog has gained wide adoption, it can often be overwhelming to both know and understand where to go to find answers to questions."
"The correlation between the logs and the metrics needs improvement as most cases, we might use another logging tool (that is cheaper in cost) which we then have to link together."
"They could have better log reporting."
 

Pricing and Cost Advice

"The cost is high."
"We purchased the license once and had the option of selecting the number of user licenses."
"My company pays to use AlertSite, but I'm unsure of the exact costs because it depends on how many monitors you have."
"The solution is fairly priced but history and log storage can get costly depending on your needs."
"Our licensing fees are paid on a monthly basis."
"The pricing and licensing through AWS Marketplace has been good. It would be nice if it was cheaper, but their pricing is reasonable for what it is. Sometimes, for their newer features, they charge as if it's fully fleshed out, even though it is a newer feature and it may have less stuff than their other items."
"Pricing is somewhat affordable compared to other solutions but in order to really lower the costs of other products you need to plan very carefully your resources usage, otherwise, it can get expensive real quick."
"This solution is budget friendly."
"Sometimes it's very hard to project how much it will cost for the monthly subscription for the next month when you add certain features. Having better visibility of the cost would give a better experience."
"My advice is to really keep an eye on your overage costs, as they can spiral really fast."
"The solution's pricing depends on project volume."
