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.
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.
