Effective as a vector store, serverless architecture but there aren't enough security features

The pricing aspect is a concern. The service is way too costly. For the past month, I used only 30 to 40 MB of data, and the cost was $500. AWS could improve pricing. Even being serverless, it incurs charges during idle times. For just holding data, you need to create a list. AWS should add an option to make data idle, so it won't include computing charges. They charge for OCU units based on the time the serverless solution is up, not on indexing or retrieval speed. Once the service starts, it starts getting billed. It would help if there were an option to limit computing. When using it as a database, storing data without frequent fetching would save computing costs.

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 would definitely recommend Amazon OpenSearch Service to other professionals due to its fast and reliable search capabilities."

"Our customers have seen tangible benefits from Amazon OpenSearch Service, especially in terms of their applications running smoothly, so they do get a return on investment."

"We retrieve historical data with just a click of a button to move it from cold to hot or warm because it's already stored in the backend storage"

"The business analytics capabilities are the most important feature it provides."

"Amazon OpenSearch Service has enhanced our organization's ability to store and search large amounts of data efficiently."

"This service already sorts data like vectors. They have classified the storage pre-defined."

"Amazon OpenSearch Service provides a managed database solution, so we don't need to manage everything ourselves."

"The customer service is excellent, rated nine out of ten."

"The observability is great and valuable."

"One of the excellent features is the service analyzer, which is truly impressive."

"We liked the built-in calculation of health scores."

"Splunk ITSI offers a valuable visualization tree that allows us to map and analyze dependencies and co-dependency within our environment."

"Alerts and episodes are valuable to me."

"The most valuable feature of ITSI is the service KPIs. No other tool provides you with the same level of observability and enterprise security or the search and reporting applications."

"We save substantial time on monitoring tasks because we don't have to search for what we need. Everything is packed, so you can drill down to the end values by just doing the kit. We don't spend a lot of time on this. Splunk ITSI is easy to use and not time-consuming."

"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."

Cons

"They can enhance data visualization."

"One improvement I would like to see is support for auto-scaling."

"It would be beneficial to have some level of customization available in the managed service, tailored to the specific use cases of the end users."

"We faced documentation challenges during integration after migrating from Elasticsearch to Amazon OpenSearch Service. Better documentation on integration, query handling, and a more user-friendly UI could enhance the product."

"One improvement I would like to see is support for auto-scaling."

"In terms of data handling capabilities with Amazon OpenSearch Service, they can be complex and managing data in comparison to other SIM solutions is a major drawback, as it is very hard to handle the data."

"The price is fair yet leans towards the expensive side. I'd rate it five out of ten with respect to capabilities vs. cost."

"The pricing aspect is a concern. The service is way too costly. For the past month, I used only 30 to 40 MB of data, and the cost was $500. AWS could improve pricing."

"Splunk ITSI should include ease of integration and more templating."

"ITSI is an almost perfect tool, but there is room for improvement in a few features like the deep dive and multi-KPI alerts. We're using most of the features like service API, coding searches, and aggregation, but our team members hardly use multi-KPI and deep dive. We don't use the multi-KPI or deep dive because everything is available in the service KPI. I don't think this feature is necessary."

"Splunk ITSI's UI needs to be more interactive and user-friendly."

"One thing ITSI could improve on is the maintenance windows. I have a huge case where I had to implement something related to the maintenance window. If you try to look up the issues in ITSI, you have to check the incidents individually, and putting hundreds of hosts in maintenance can be a hindrance."

"The solution should integrate more features in NEAP."

"We'd like them to show more inputs on the dashboard."

"It is pretty okay. I am not sure whether the current release has already moved to the new framework where instead of the glass tables, we can directly use the Dashboard Studio. It would be nice to have that integrated into the same framework."

"We're getting alerts with delays of maybe five minutes, however, we'd like to see real-time alerting in the future."
