DevOps engineer at Yara International
It is not open-source, and I have to be a partner to get more access to the products.

Splunk AppDynamics is seen as expensive but valuable for advanced monitoring, with costs varying by company and features used.
I find the cost of IBM Instana Observability to be very affordable compared to competitors because the pricing mechanism is based on the host that we monitor, unlike other competitors such as DataDog and Dynatrace, whose pricing is based on other factors.

It is not that costly, especially since we only use two instances.
Software engineer at EJADA

Featured Reviews

FranciscoGálvez - PeerSpot reviewer
Technical Manager at a consultancy with 1-10 employees
Observability has improved collaboration and predicts failures across distributed services
From my perspective, IBM Instana Observability is quite technical. Compared to some competitors, it offers an abundance of information about system performance but lacks planning or capacity planning information. You do not receive reports with recommendations; instead, it provides only the technical layer. Other companies, like Compuware, give more functional information about your environment, while IBM Instana Observability provides only limited functional insights. This means you often must interpret the data independently. Unlike other tools that can offer recommendations to save resources or costs, IBM Instana Observability does not provide that functionality. On the bright side, it is much more affordable than some other options, but it isn't complete. If you want full functionality with IBM Instana Observability, you also need to acquire other products for additional insights in monitoring areas, such as networking monitoring tools or similar products. For instance, we often recommend Turbonomic, which provides complementary insights. One potential feature that could improve IBM Instana Observability is the ability to translate KPIs into monetary terms. It would be interesting to have a product that integrates IBM Instana Observability with Turbonomic, as Turbonomic can utilize data from IBM Instana Observability to inform you about unnecessary spending and suggest whether you can consolidate servers or optimize containers for quicker response times. Implementing some level of simulation or capacity planning would greatly enhance the current capabilities of IBM Instana Observability.

Performance Test Engineer at TANIM CONSULTING, LLC
Real-time monitoring has improved our banking API performance and supports detailed business transaction analysis
The real-time monitoring is what we can see for anything that is needed in terms of CPU, memory, or the connections or the sessions related. It's real-time monitoring of performance of each of the components, which is what we need and use all the time. It's highly effective, I would say. Infrastructure visibility, transaction monitoring, to check the actual user experience in terms of the response time, MRT and all those things. We do the component monitoring like the API performance and the connections and all those things, but we also do the business process monitoring and business transaction monitoring.
