The next release of Splunk Observability Cloud should include a feature that makes it so that when looking at charts and dashboards, and also looking at one environment regardless of the product feature that you're in, APM, infrastructure, RUM, the environment that is chosen in the first location when you sign into Splunk Observability Cloud needs to stay persistent all the way through.

Featured Reviews

Senior Systems Administrator at a tech vendor with 10,001+ employees
Delivers comprehensive and customizable system management with increased efficiency
The best features I have found are that it is very customizable, which would be number one, and very extensible through the use of scripts and triggers. The visual look of the interface is very easy to understand what is happening and somewhat why it's happening. It may sound facetious, but it really is everything about it. Everything works exactly the way it's meant to, a dream come true for anyone who's administering systems because it gives you all the information that you want and all the actions you want to take, all in one place. The benefits I have seen from using it so far include the ability to know in advance and take actions based on the information the tool gives you.

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.

Helps reduce response time but has room to improve customization complexity
We are not working on simple standalone solutions like Kaspersky DDoS Protection or Hybrid Cloud Security. Once you understand Zabbix, then it is easy to customize those web pages and graphs for our customer use. It is fully automated to your requirements. Zabbix is working fine with no issues, and I am satisfied with it. We have combined Zabbix and SolarWinds. The integration works fine, and it is easy to integrate Zabbix with the IT environment. We were trying to purchase MDR (Managed Detection and Response), but we are not working on that. I don't have real experience with MDR. We are using Falcon software for that. We are working with Falcon Complete, not with Sandbox. We are not using Kaspersky for business or cloud protection. For that, we are using Zabbix CrowdStrike Falcon Complete solution. I have given this review an overall rating of 8.

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
