Application Manager Software

One thing I've learned is that Session Replay isn't meant to replace good event tracking. Sometimes I can see exactly what a user is doing, but without the right custom events, I'm still missing the "why" behind those actions. That's where good instrumentation makes all the difference. LogRocket is already a great tool on its own, but once you combine it with a solid analytics strategy, it becomes much easier to understand what's actually happening instead of just watching a replay. Review collected by and hosted on G2.com.

Every time we roll out a new feature, I like to spend some time watching how people actually use it. There's almost always a gap between the way we think something will work during development and what real users end up doing. LogRocket is usually one of the first tools I open after a major release. More than once, I've noticed buttons people completely overlook, forms that create unnecessary confusion, or workflows that seem obvious to us but not to the people using the product. Those little discoveries have led to improvements we probably wouldn't have made otherwise. That's what I value the most. Instead of relying only on charts and usage metrics, I can actually see how people interact with the product, and that gives me a lot more confidence when it's time to decide what to improve next.

The biggest challenge is balancing observability with cost. As applications scale and generate more logs, metrics, and traces, it's important to optimize what is collected to keep costs under control. Creating advanced dashboards and custom queries may require additional expertise. Managing data retention and ingestion costs requires careful planning. Some alerts need fine-tuning to avoid unnecessary notifications. Review collected by and hosted on G2.com.

New Relic solves the problem of limited visibility into application performance and system health. Instead of relying on separate tools for logs, metrics, and performance monitoring, it provides a unified platform to monitor applications, infrastructure, and user experience. Detects performance bottlenecks and application issues in real time. Centralizes metrics, traces, logs, and error data in one platform. Helps identify the root cause of production incidents faster. Provides proactive alerts to minimize downtime. Monitors APIs, databases, infrastructure, and application performance from a single dashboard. In my day-to-day work as an SDET, I use New Relic to monitor application performance after deployments, investigate API latency, analyze errors, and validate system stability. Having end-to-end visibility into application behavior helps me collaborate more effectively with developers and operations teams. The biggest benefit is faster incident resolution. By correlating performance metrics, traces, and errors in one place, New Relic reduces troubleshooting time, improves application reliability, and helps deliver a better experience for end users.

Although Datadog is one of the most comprehensive monitoring tools I've used, there are a few areas where it could improve. Pricing can become expensive as the number of hosts, logs, and monitored services increases. The large number of features can make the platform overwhelming for new users. Building advanced dashboards and queries sometimes requires a learning curve. High log volumes need careful management to avoid unnecessary costs. Some alerts require fine-tuning to reduce noise and avoid alert fatigue. For me, the biggest challenge is cost management. As monitoring requirements grow, it's important to optimize log retention, dashboards, and alert configurations to keep expenses under control. Review collected by and hosted on G2.com.

My only complaint is that some parts of the interface can feel cluttered, making it take longer to find certain settings. Aside from that, the product works really well. Review collected by and hosted on G2.com.

Sentry helps us quickly identify, track, and diagnose bugs across both our backend and frontend applications. Whenever an issue occurs, it automatically captures detailed error information and sends notifications to our email and Slack, allowing our testing and development teams to respond quickly. This has significantly reduced the time it takes to detect and resolve issues before they impact users. Being honest, Sentry has definitely been a game changer for our development workflow.

Sometimes the website will just not load, and I have to wait quite a few times. Also, Metric Explorer sometimes crashes if it has a tad bit more data to share. Review collected by and hosted on G2.com.

I use Coralogix for monitoring logs, alerting, and tracing, enhancing developer work and on-call team efficiency. It also optimizes costs with the TCO optimizer and integrates seamlessly. Review collected by and hosted on G2.com.

I don't like how I can't really customize status.xocat.online, so that could be improved. I mostly don't like the customization because I have to pay to access that, but it would be great if we could build our own website instead of just being stuck with Better Stack's template, even if it was paid. Review collected by and hosted on G2.com.

I use Better Stack to monitor my website's downtimes, saving me from having to build my own monitoring site, which I couldn't do. It's invaluable as it informs both me and my users about site issues. Review collected by and hosted on G2.com.

GPU monitoring. We run inference workloads on GPU machines and I can't see GPU utilization inside CubeAPM, so I still have to check that elsewhere. Hoping they add this at some point. Review collected by and hosted on G2.com.

Less time jumping between tools when something goes wrong. That's the main thing. When our image processing API starts throwing errors or latency spikes, the on-call team can trace back to the cause a lot faster now.

Cost is also much lower than what we were paying with New Relic. Flat pricing works well for us, so as we keep adding services, the bill stays predictable. I think that alone made the switch worth it. Review collected by and hosted on G2.com.

The main area that could be improved is the initial learning curve. Instana provides a large amount of data, but the interface can feel quite dense when you first start using it, especially when navigating between services, traces, infrastructure metrics, and incidents. It was not always immediately clear which view was best for a particular task, such as investigating a slow transaction, checking infrastructure health, or understanding the dependencies between services. Review collected by and hosted on G2.com.

I use IBM Instana for real-time application performance monitoring, reducing investigation time, identifying bottlenecks faster, and understanding issue impacts across our environment. It solves problems with limited visibility in complex applications by connecting traces, metrics, and dependencies. Review collected by and hosted on G2.com.

I find the licensing and pricing model complex, and it's sometimes difficult to predict as our environment scales. There's a learning curve for new users due to the large number of features and configuration options. Creating highly customized dashboards and reports can sometimes be less intuitive than expected. Improving ease of use, reporting flexibility, and cost transparency would definitely make the overall experience better. The main areas of improvement are pricing and transparency, ease of onboarding for new users, and more intuitive dashboard customization. While the platform is very powerful, simplifying access would enhance my user experience. Review collected by and hosted on G2.com.

I use Dynatrace for application performance monitoring and infrastructure monitoring. It analyzes logs, detects issues proactively, performs root cause analysis, and offers end-to-end visibility. This helps reduce downtime, improve system reliability, and ensures application health, user experience, and resource utilization are well managed. Review collected by and hosted on G2.com.

What I dislike about OpManager Nexus is that the initial setup and configuration can feel complex, especially when adding many devices, integrations, and custom monitoring rules. The interface contains a lot of information, so new users may need time to understand the dashboards and navigation. Performance can also depend on the size of the environment and how well the system is configured. Some advanced features may require additional licensing, which can increase the overall cost. Although the documentation is helpful, more guided onboarding and simpler explanations of the AI-driven insights would improve the experience. Review collected by and hosted on G2.com.

OpManager Nexus helps solve the problem of managing multiple network devices, servers, applications, and alerts across different tools. It gives me one central place to monitor performance, identify outages, and investigate issues before they seriously affect users. Real-time alerts and performance reports reduce the time spent manually checking systems, while automation helps minimise repetitive monitoring tasks. This has improved response times, reduced downtime, and made it easier to prioritise critical problems and use IT resources more efficiently. Review collected by and hosted on G2.com.

The hierarchical grouping for OT devices is still pretty manual. Every time maintenance swaps a sensor or adds a new actuator I have to go rebuild the tree structure by hand, and if you forget one sub-group the maps look like a jigsaw with missing pieces. It’s not a deal-breaker, but after a busy shutdown week it feels like busywork that should be smarter by now. Review collected by and hosted on G2.com.

We used to fly blind on predictive maintenance—machines would just fail and we’d scramble. Now PRTG gives us trending curves I can actually show the maintenance guys in plain English. We cut unplanned downtime by roughly 40 % on the critical lines and shaved about 18 % off our quarterly energy bill because we finally saw which machines were idling at full power overnight. The ROI showed up in the first six months. Review collected by and hosted on G2.com.

It is worth noting that the tool is still in heavy development. While the team is clearly trying their best and moving quickly, not all convenience features are present yet compared to older, more bloated competitors. However, the stability and speed of the core features more than make up for the current gaps in the "nice-to-have" category. Review collected by and hosted on G2.com.

For an engineering team without a dedicated DevOps department, Dash0 removes the operational burden of 'tool-chaining' by providing a unified, OTel-native environment that automatically correlates logs and traces, allowing us to maintain full visibility into our services without needing a specialist to manage complex infrastructure or proprietary agents. Review collected by and hosted on G2.com.

I don’t have any major complaints, but one aspect that could use improvement is the internal documentation and the number of manual steps involved in workflows. If there were more structure and clearer guidance in these areas, I believe productivity could be enhanced even more. Review collected by and hosted on G2.com.

Last9 is solving the problem of unreliable, difficult-to-understand systems in modern distributed architectures. As applications grow more complex, it becomes harder to maintain uptime, identify the root cause of failures, and ensure that services meet reliability goals. Last9 addresses this by providing structured SLO (Service Level Objective) management, real-time observability, and automated insights into system performance.

For me, this has been extremely beneficial because it helps me:

Detect issues early before they become customer-impacting incidents.

Reduce time spent on debugging, since Last9 surfaces the exact services or dependencies causing reliability risks.

Track reliability in a measurable way through SLOs instead of relying on subjective judgments.

Focus my efforts on what truly matters, thanks to clear error budgets and actionable alerts.

Deliver more stable releases, ensuring better user experience and fewer production escalations.

Overall, Last9 helps turn reliability from a reactive activity into a proactive, data-driven process — which boosts my efficiency and confidence in managing high-scale systems. Review collected by and hosted on G2.com.

The biggest headache with Site24x7 is its dated, cluttered interface. It makes even basic configuration settings feel unintuitive to find, which creates a steep learning curve for new teams. Although it packs a huge amount of functionality into a single platform, the sheer data density often works against you. The default settings can be overly sensitive, leading to serious alert fatigue as engineers get bombarded with false alarms unless everything is heavily customized.

On top of that, their complex, add-on-heavy billing model can be very frustrating to navigate. The base price may look affordable at first, but it can quickly escalate with unexpected upgrades for extra logs, advanced metrics, or additional monitors. Dealing with critical technical issues can also test your patience, since users often report having to go through multiple tiers of basic customer service before finally getting connected to engineers who can actually resolve deeper infrastructure problems. Review collected by and hosted on G2.com.

Site24x7 addresses the problem of fragmented IT monitoring by replacing isolated tracking tools with a single observability platform.

Problems solved and immediate benefits: It reduces tool fragmentation by consolidating website, server, cloud, and network monitoring into one dashboard, so your team doesn’t have to constantly switch between different systems. It also helps eliminate blind spots by continuously testing user journeys from over 130 global locations, allowing you to spot regional outages or slow load times before your customers notice. When troubleshooting is slow, its AI-powered root-cause analysis can automatically pinpoint why a system crashed, cutting Mean Time to Resolution (MTTR) from hours to minutes. Finally, it reduces manual intervention by triggering automated scripts or server restarts as soon as a threshold is breached, resolving routine infrastructure glitches automatically so engineers can stay focused on development.
