VijayKumar27 - PeerSpot reviewer
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.

"Amazon OpenSearch Service provides a managed database solution, so we don't need to manage everything ourselves."
"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."
"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 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."
"The solution's scalability is fine."
"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."
"The most valuable features are the agility, being able to ingest many data sources with no limitation on capacity."
"We can automate routine tasks. We're able to create alerts, reports, scheduled searches, et cetera. It's helping us to save time."

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

"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."
"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."
"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."
"ITSI could benefit from a security model that would allow operations team members to get involved in model building, KPI implementation, and model maintenance, while maintaining appropriate segregation of duties."
"We also faced challenges relating to UI development."
"The dashboard queries should be improved. More queries should be suggested in order to produce better dashboards."
"Splunk ITSI's UI needs to be more interactive and user-friendly."

"We're getting alerts with delays of maybe five minutes, however, we'd like to see real-time alerting in the future."
"The dashboard function inside the individual episodes, not at the ITSI Notable Event Aggregation Policy level but actually at the correlation search layer, is an area where improvements are required."
"The user interface visualization could be improved."
 

Pricing and Cost Advice

Information not available
"Splunk ITSI is expensive."
"It would have been good if the product cost was much lower."
"It is interesting. I am not involved that much lately, but if I recall correctly, you license primarily on the volume of data that you are using in Splunk ITSI, but there is no way Splunk can ever check if that is true, so that is interesting. We are not doing it, but someone can pretend to just use 10%, and it would be super cheap. It is tricky, but it is more tricky for Splunk than for us."
"I would prefer that the price be reduced, as it would be easier to implement it and to sell it."
"Splunk is pretty expensive, but it gives you a decent insight into the data. It is easy to learn, and ITSI has a great interface. You can run those queries and pass the data. I"
"Its pricing has been changed as per the market. You get a good support service with it as well. They have 24/7 customer support. There is a portal, and if you are having issues, they are available in order to resolve them. So, its pricing isn't too much."
"It depends on how big an organization is. If we have a lot of resources, the licensing needs to be upgraded. If we have a small environment, the licensing cost is definitely going to be less."
"Pricing has some room for improvement."
