Aids significantly in the threat-hunting process and provides a score-based evaluation of user experience

There are many valuable features, but understanding end-user response times stands out. It provides a score-based evaluation of user experience, helping customers quickly pinpoint whether issues originate from the network, server, client, or application. Additionally, it facilitates in-depth analysis of application dependencies. The retrospective network analysis capability of Observer GigaStor has been beneficial. It's a pivotal feature for network performance solutions. However, I prefer to consider the entire solution suite - GigaStor, along with GigaFlow and Apex - for comprehensive network visibility and monitoring. So, I prefer to integrate all three solutions to provide the best visibility. They complement each other well, with Apex aggregating and correlating data from both GigaStor and GigaFlow to enhance environmental understanding and troubleshooting efficiency.

Alerting improves incident response across teams and enables faster awareness before customer impact

Splunk Observability Cloud could be improved in terms of integrations with more technical add-ons, such as Zoom. Although they have one with Zoom, it's not available in the cloud, so having that feature would be beneficial. Essentially, Splunk should continue expanding to create easier ways to ingest logs from different products. The out-of-the-box customizable dashboards in Splunk Observability Cloud are very effective in showcasing IT performance to business leaders. However, there are aspects that could be improved, such as linking dashboards to one another. While IT leaders may not drill down, it's crucial to create levels of dashboards for technical users to find root causes, making it effective for stakeholders.

Cons

"Maybe the graphical user interface could be simplified to allow people to use it more easily."

"Graphics need improvement. Because a lot of the information there you have to input first in some case to have full potential. It could be more automated."

"Maybe the graphical user interface could be simplified to allow people to use it more easily. It's already good, but they can work more on it to make it even easier."

More Observer GigaStor cons

"The feedback is that Splunk Observability Cloud is forcing me to modify my logs that I am ingesting in Splunk Observability Cloud in a specific format."

"Regarding the negative side, I think the licensing can be much better because it is based upon host units and there is additional licensing for the number of traces that I can bring in."

"The initial setup of Splunk Real User Monitoring (RUM) was easy. The solution is deployed on-premises."

"I would like to see an improvement and some innovation in the customer interface."

"The solution should have more sensors regarding fiber intelligence for security measures."

Pricing and Cost Advice

"It depends on the requirements you have. There are three types of license. There's the updates license, the work group license, and the workstation license."

"It's quite expensive."

"Splunk's infrastructure monitoring costs can be high because our billing is based on data volume measured in terabytes, rather than the number of devices being monitored."

"Splunk offers a 14-day free trial and after that, we have to pay but the cost is reasonable."

"The solution's pricing is costly."

"I am not in that circle, but we are currently licensing based on our queries. That is working out for us. Previously, it was by volume of data, and now, we can store as much data as we want."

"It appears to be expensive compared to competitors."

"Splunk Infrastructure Monitoring is an expensive solution."

"Splunk Observability Cloud is expensive."

"The product is a bit expensive considering the competition but the company may negotiate the price."
