Unified observability has improved real-time governance and now drives data-led decisions
Log Observer Connect is embedded here, but we are facing some delays in centralized log collection and analysis, which can be further fastened. We are collecting all the data metrics and decision-making insights, but all these data-driven decisions coming from different applications are not connected somewhere. A consolidated form or correlation of these insights is not happening between each other due to which we feel we are missing something significant. Some generalized feedback includes that predictive alerts or alarms which can be integrated with AI-driven alarms and alerting features should be established so that there is AI-driven intelligence and anomaly detection happening with a complete systematic process in service delivery. Application dependencies are huge, and business and operational dashboards should be improved. Right now there are very interactive custom dashboards, and every now and then, the personalization of enhancements keeps happening. KPI monitoring, executive reporting, and analytics have definitely been introduced to a great extent. There are few things in cloud-native monitoring, such as integration with AWS and Azure, where we sometimes do face lags. Those things can definitely be improved upon. I have used Datadog and Dynatrace before using Splunk Observability Cloud. Datadog was definitely recommended by most of our peers because of its very strong comprehensive observability and very strong and unique dashboard systems. Dynatrace was also very good because they have offered a lot of AI-driven analysis methods and processes, which was helping our organization a lot. Since our organization has a very strong IT ecosystem for agriculture, very different kinds of customized things are required.

Unified monitoring has improved SaaS troubleshooting and reduces MTTR for remote users
In my opinion, the best features Zscaler Digital Experience (ZDX) offers are Zscaler Digital Experience (ZDX) Insights and scoreboards for quick health visibility. I can analyze the path to identify what the bottleneck of the application is, and I can also diagnose the endpoint for device-level root cause analysis, which is very helpful. Scoreboards and root cause analysis have helped my team significantly, as a scoreboard represents a 100% healthy application and connection, meaning no issues can be identified. During troubleshooting, I definitely need to visit the Insights and scoreboard to understand the level of connectivity the user is experiencing. Zscaler Digital Experience (ZDX) has positively impacted my organization by being beneficial for me as a troubleshooter and administrator, as I can identify all types of network performance-related issues, leading to faster resolutions of user complaints, improved collaboration between network, desktop, and security teams, and more productivity in identifying issues before they affect users. The outcome shows a 40 to 50% reduction in MTTR for SaaS applications and better SLA reporting for critical apps like Zoom and Salesforce, among many more applications which can be integrated with tenant authorization.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The company has many systems that the customer is paying to access. Splunk APM issued via AppDynamics helps find problems in the feed. It reduces the risk of supervising all the devices. I can supervise the flow and simulate the conditions of the repository across several dashboards to show what's happening at the moment."
"The tool's stability is great."
"It is a good tool. It allows you to set alerts for application and infrastructure monitoring, and it allows you to create dashboards."
"The features I appreciate the most about Splunk Observability Cloud are the ServiceNow integration feature, which is very seamless, and that's probably my favorite since ServiceNow is big in the observability industry."
"Splunk Observability Cloud has helped to improve my operational performance because it is useful for my company, helping to solve issues, reduce the manpower, and reduce the man-time to solve it."
"The dashboards are the features of Splunk Observability Cloud that I appreciate the most, providing visual representation of all data and text, which has benefited my organization by speeding up people's jobs and allowing a place to monitor all logs, as there are usually thousands of entries coming in which can become very disorderly."
"It has been beneficial for our IT infrastructure."
"Customer service and technical support respond very quickly."
"Zscaler Digital Experience (ZDX) positively impacted my organization by providing Zero Trust Network Access, which many organizations are moving towards."
"Zscaler Digital Experience (ZDX) has positively impacted my organization by being beneficial for me as a troubleshooter and administrator, as I can identify all types of network performance-related issues, leading to faster resolutions of user complaints, improved collaboration between network, desktop, and security teams, and more productivity in identifying issues before they affect users."
"Regarding the benefits of Zscaler Digital Experience (ZDX)'s traffic analysis for my IT operations, I believe it greatly supports our needs."
 

Cons

"Splunk could be better integrated with configuration manager solutions so we can automatically resolve issues without human interference."
"I haven't seen any return on investment yet, but I do definitely expect to see ROI soon, once we bring in everything and reduce workload."
"Unified visibility is not there."
"To improve Splunk Observability Cloud, we need more applications to be included in the observability so that more applications can have agents to monitor them and bring that information to the cloud."
"Support from Splunk is not very helpful because Splunk doesn't have a dedicated APM; they only have one APM engineer in Korea."
"The initial setup of Splunk Real User Monitoring (RUM) was easy. The solution is deployed on-premises."
"Splunk Observability Cloud could be improved with better integration with AppDynamics, as we know that's coming, however, it is an issue we've had between the OpenTelemetry and the AppDynamics collector."
"Splunk APM should include a better correlation between resources and infrastructure monitoring."
"I have noticed drawbacks within Zscaler Digital Experience (ZDX), as the sales team is too arrogant and too aggressive, playing politics, but the product itself is very good."
"Zscaler Digital Experience (ZDX) is comparatively an expensive product."
"Support responses are excellent, but for more complex cases, it sometimes takes longer."
 

Pricing and Cost Advice

"Splunk offers a 14-day free trial and after that, we have to pay but the cost is reasonable."
"The product is a bit expensive considering the competition but the company may negotiate the price."
"Splunk APM is a very cost-efficient solution."
"Licensing cost is the biggest argument I get from those divesting from Splunk. There are those within our organization who say we are going to go to other tools since Splunk is too expensive."
"Splunk's infrastructure monitoring costs can be high because our billing is based on data volume measured in terabytes, rather than the number of devices being monitored."
"I would rate the price of Splunk Infrastructure Monitoring as an eight out of ten, with ten being the most expensive."
"The pricing is reasonable."
"I am not in that circle, but we are currently licensing based on our queries. That is working out for us. Previously, it was by volume of data, and now, we can store as much data as we want."
