There is room for improvement in the alerting system, which is complicated and has less documentation available.

Featured Reviews

Abdullah Baig - PeerSpot reviewer
An easy-to-use solution that has a good dashboard, performs well, and provides flexible pricing
Sentry was easy to learn compared to New Relic and Azure Monitor. I saw some valuable input. It took us the least amount of time to see how Sentry is valuable. It took just a few minutes. Session Replay provides a replay of the recorded errors. It is a good feature. Azure Monitor does not have this feature. The error reporting is straightforward. We can see everything that we need to see. The dashboard seems pretty fine. The product performs well. We can see the user's IP addresses.
Taiwo Ige - PeerSpot reviewer
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.
