Johnny Suleiman - PeerSpot reviewer
Scalability is a key feature as it allows easy scaling of the platform without downtime
OpenSearch is used as a search engine for specific logs, mainly in e-commerce and monitoring the logs themselves. It is very valuable for e-commerce, enabling data analysis on application logs and customer behavior, and can be integrated with other services, including AI and machine learning…
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

"They have the good documentation in the help text and that is the reason the Amazon is the perfect solution in the current market."
"The most valuable features of Amazon Elasticsearch are ease of use, native JSON, and efficiency. Additionally, handles many use cases and search grammar was useful."
"Amazon OpenSearch Service provides a managed database solution, so we don't need to manage everything ourselves."
"In case there is a failure, Elastic manages everything well, and there no major downtime."
"The stability of the product is good."
"The business analytics capabilities are the most important feature it provides."
"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"
"Regarding valuable features of the solution, we found with the process, which we have used in both cases where we used the solution that while you're seeing the streaming of data, you can analyze in the initial phase what sort of data you are streaming and whether it is valuable."
"ITSI includes a feature called a glass table."
"The most valuable features are the agility, being able to ingest many data sources with no limitation on capacity."
"The most valuable feature is event correlation, which ensures that only one ticket is generated per issue, eliminating duplicates and reducing noise from multiple alerts."
"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 has been stable."
"Splunk ITSI helps us secure our environment by allowing us to create automatons that run when alerts are triggered."
"Splunk's intuitive interface and scalability make it accessible to non-technical users, and its capacity to monitor every millisecond of data across multiple applications is truly impressive."
"I find the episode review, glass tables, and correlation search features very useful."
 

Cons

"They can enhance data visualization."
"Amazon Elasticsearch can improve the bullion in the near search and the ease of integration with Kibana. Additionally, there could be more flexibility in the configuration and documentation."
"The configuration should be more straightforward because we had to select a lot of things."
"One improvement I would like to see is support for auto-scaling."
"The price is fair yet leans towards the expensive side. I'd rate it five out of ten with respect to capabilities vs. cost."
"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."
"One improvement I would like to see is support for auto-scaling."
"There is a problem with the database. Amazon only provides the hosting to run our applications bias, but there is no option to manage the database within the Elasticsearch product."
"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."
"It would be good if an interface was included in the next release."
"Splunk ITSI's UI needs to be more interactive and user-friendly."
"We have problems doing upgrades and operating alternate new versions."
"Splunk ITSI consumes a lot of CPU resources."
"We're getting alerts with delays of maybe five minutes, however, we'd like to see real-time alerting in the future."
"I believe the refresh time should be faster."
"The biggest improvement area is making it open to developers. Right now, it is very closed. It can only be downloaded by people who have a license to and not everyone. If it is open to everybody, more people will use it."
 

Pricing and Cost Advice

"Compared to other cloud platforms, it is manageable and not very expensive."
"You only pay for what you use."
"The solution is not expensive, but priced averagely, I will say."
"There is a community edition available and the price of the commercial offering is reasonable."
"Splunk ITSI is expensive."
"Splunk ITSI is a pay-per-use service that is priced fairly based on the amount of data we use."
"I wouldn't say there's been an issue with the solution's pricing because we went through the AWS marketplace and negotiated directly with Splunk."
"The cost of the modules is a bit high for non-global companies, making it difficult for them to afford Splunk ITSI."
"Pricing has some room for improvement."
"Pricing was pretty good, and it is possible to just add on the features we want."
"Splunk ITSI is an expensive tool, and we need to purchase the utility license."
"Splunk ITSI is expensive; however, with the appropriate use case, it justifies the cost."
