Unified monitoring has improved end-to-end visibility and reduced detection time across apps
When we have too many detectors in place for one particular app, such as when I have created 50+ detectors through my account, the entire page becomes a bit loaded when creating the 51st detector, feeling heavy and taking time to load. Additionally, it throws random errors; for example, when we try to save one detector, it might throw some random error which is not even related, with something else being wrong, not that particular error, but the underlying root cause might be different. Sometimes the error is just "some problem occurred," and we are not able to point out what the real cause is. This mainly happens when we have too many detectors or too many alerts in place rather than a standard number. One more thing is in the alert rules; if we have a main general alert, and instead of creating a new detector, we are adding a new rule under one detector, when the number of rules also increases, such as when we have 10 or 15 rules under one generic detector, that again creates the same kind of problem, taking some time to save that particular newly added rule, and it might not save at times, just keeps on spinning. Those are the two drawbacks which I spotted recently; other than that, everything looks perfect.

Offers steady access and reliable support but could benefit from better integration and user-friendly insights
Regarding future updates, I would like to see Zscaler prioritize pricing and integrate more with multiple products. Multiple integrations with various platforms would enable some sort of automation. Zscaler provides real-time insights, but it is not reaching the end users properly, which is something Zscaler should improve because it should be user-friendly for understanding what Zscaler is offering. When there is too much technology, people cannot understand it, so it should be very simplified, and there should be some ways for users to gain knowledge about the product themselves. Zscaler's ability to analyze millions of telemetry data points in real-time is still somewhat unclear to me; perhaps that level of knowledge has not been reached by me or the end users, indicating that Zscaler has to focus on that area.

Quotes from Members

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

Pros

"Splunk Observability Cloud has helped improve my operational performance; previously, we used Elastic for similar purposes, and this has allowed us much more visibility into what we're working on with usable dashboards and metrics, which has been awesome."
"It is a good tool. It allows you to set alerts for application and infrastructure monitoring, and it allows you to create dashboards."
"It is a great resource for us because we have so many different data sources and to be able to aggregate that and put it through a concise dashboard or an alert really helps."
"The best features in Splunk Observability Cloud are the metrics; I can see any logs or anything related to the server or services we want to monitor, and the metrics are a good function."
"The most valuable feature is the ability to customize dashboards based on my queries or any other customization I may need."
"Once configured correctly, the analysis reporting the Splunk APM provides is better than that of the other APM tools."
"The features I have found most valuable are log searching and log analytics, both of which are quick features."
"The features of Splunk Observability Cloud that I prefer the most are its all-encompassing licensing model, which is comparatively better than others in the market."
"Zscaler Digital Experience (ZDX) positively impacted my organization by providing Zero Trust Network Access, which many organizations are moving towards."
"Regarding the benefits of Zscaler Digital Experience (ZDX)'s traffic analysis for my IT operations, I believe it greatly supports our needs."
 

Cons

"In the next release, I would like to see more integration with other solutions."
"Splunk APM's performance could be improved - at the moment, it's very slow and takes forever to give me what I want."
"A wide variety of logging makes log onboarding difficult."
"The clustering part of indexes can be more refined."
"There is room for improvement in customer support due to delays and standard feedback responses."
"The UI of Splunk Observability Cloud is one of the major issues; it's old and has been there for more than 10 years, acquired by other applications from other companies. It's time to reinvent how the UI is going to work with the AI modules and integrations, making it softer and cleaner."
"Unfortunately, with our current setup, we just have to implement Log Observer in a couple of instances so that we can have that integration with Splunk Observability Cloud."
"Splunk could be better integrated with configuration manager solutions so we can automatically resolve issues without human interference."
"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."
 

Pricing and Cost Advice

"I would rate the price of Splunk Infrastructure Monitoring as an eight out of ten, with ten being the most expensive."
"The solution's pricing is competitive. I rate the solution's pricing a seven out of ten. The price of the solution could be cheaper."
"Splunk Infrastructure Monitoring is an expensive solution."
"Splunk APM is expensive."
"Splunk offers a 14-day free trial and after that, we have to pay but the cost is reasonable."
"Splunk has been fairly expensive, but it has been predictable."
"The product is a bit expensive considering the competition but the company may negotiate the price."
"The price of Splunk APM is less than some of its competitors."
