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…
Srinivasulu Soolluru - PeerSpot reviewer
It speeds up incident response by automating alerts and ticket creation
When configuring a dashboard, we can write search criteria. Based on the search criteria, the dashboard shows all the alerts, including the alert time, creation time, and a summary description of the alert. When you add an extra column, such as the user that triggered the alert, the next time he refreshes the dashboard, he wants to know that the alert is acknowledged. We want to improve that comment feature. In the Service Analyzer, we monitor the network infrastructure services and have a KPI for each service. When the value exceeds the threshold value, we can add the colors. For example, we can set it to green when the threshold value is within the limit. If it is red, then the value has passed the threshold. We want more colors in the service analyzer to display all these features.

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 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 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."
"This solution has numerous advantages. It's extremely simple to configure. Either digital monitors or single-URL monitors are simple to configure and build."
"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."
"The alerting capabilities of AlertSite were really helpful."
"There are custom reports available along with the inbuilt reports."
"The feature that stood out to me most from Splunk IT Service Intelligence (ITSI) was automated dashboarding or reporting. The solution lists the severity level of issues, and the response times."
"ITSI's most valuable feature is that it's easy to integrate DLP."
"Instant usability of gathered event metrics is available. We have metrics data from systems, and we can use that to instantly get system status and trends."
"I particularly like the preview feature because it provides a prompt experience for impact analysis."
"Having worked closely with Splunk support engineers, I've observed their high capabilities in resolving issues."
"One of the excellent features is the service analyzer, which is truly impressive."
"Splunk ITSI helps us secure our environment by allowing us to create automatons that run when alerts are triggered."
"One particularly useful feature of Splunk ITSI is the ability to create custom services."
 

Cons

"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."
"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."
"Additionally, support from AlertSite is not at an enterprise level since it is not offered 24/7."
"It is not compatible with all of the product platforms that we use."
"I could use a few changes to the user interface."
"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."
"Currently, Glass tables in ITSI only display metrics related to KPIs."
"We're getting alerts with delays of maybe five minutes, however, we'd like to see real-time alerting in the future."
"Splunk ITSI generates numerous false positives and has the potential for enhancement."
"Splunk ITSI consumes a lot of CPU resources."
"We're using predictive analytics, and there are three or four algorithms. It would be helpful if this process were more standardized and scalable."
"The UI could be updated. Some elements of the KPI section aren't where you'd expect. It looks like a website from 2010 or maybe older. You can't change some things, like if it doesn't word-wrap well. For example, if you have a long list of KPIs that exceed a character limit, you need to hover over them and wait for the HTML text to pop up to see which KPI it is."
"While Splunk has existing add-ons, they are unreliable and do not provide accurate results."
"Splunk ITSI lacks out-of-the-box solutions for enterprise users."
 

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."
"Splunk ITSI is a premium application and comes with a premium price tag."
"I know that it is expensive, but I do not think there is another solution that can do similar things for that price."
"The licensing is based on data usage."
"It would have been good if the product cost was much lower."
"Splunk ITSI is expensive; however, with the appropriate use case, it justifies the cost."
"The pricing of Splunk is a bit high."
"Pricing has some room for improvement."
"Splunk ITSI is expensive compared to other tools."
