Good end-to-end voice quality monitoring and offers valuable features
The solution should have automatic baseline detection. On the per hour, per base, per week. That's usually the best. And on a per individual CI level. I know that they're working on it and when that's available then we will definitely implement it because it will reduce the effort we need to maintain all the products. Right now we have to set thresholds for every location, and it needs to be actually dynamic so if we have better thresholding, we'll have faster alarms across all our locations. We won't have to expend effort on it by resetting or checking them on a regular basis.

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.

Quotes from Members

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

Pros

"Good end-to-end monitoring"
"We use the solution to meet the needs of the customer."
"The data collection from our VMs, containers, databases, and backend components is valuable."
"The most valuable features are troubleshooting and optimizing application performance."
"The most valuable feature is the ability to customize dashboards based on my queries or any other customization I may need."
"What I appreciate most about Splunk Observability Cloud is the correlation feature, specifically the ease of correlating logs and issues to those traces to see where within the path of the business function is failing."
"I have primarily used it to go back into the past and understand why something happened. It provides enough information to do research and figure things out."
"What I appreciate most about Splunk Observability Cloud is the correlation feature, specifically the ease of correlating logs and issues to those traces to see where within the path of the business function is failing."
"Splunk Infrastructure Monitoring reduces our mean time to resolve. We are more proactive than reactive."
"Detectors are a powerful feature."
 

Cons

"The solution should have automatic baseline detection."
"All the features and functions of the solution can be improved."
"Splunk isn't an ideal tool for application performance management due to the extensive setup required."
"There's no standard use case available where you can see the utilization of the number of use cases I have."
"The integrations need to be improved for Splunk Observability Cloud."
"A lot of customers had a hard time effectively searching within the data in Splunk. There is a learning curve from searches to indexes and using all the macros that we have created. It is a little difficult for somebody who has not used it quite a bit and does not have a lot of practice with it, but the AI features that we have been hearing about through Splunk will make it a lot easier for us to use human language to search this data. That is big. That is pretty powerful, and that will help a lot with our customers."
"We have both on-prem and cloud, and the challenge is getting all our log data aggregated or streams aggregated so that it is real-time. We do a pretty good job of that, but our organization is not using it as a security platform when it can do a great job of that."
"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 would be better if some tools were integrated to be able to take action on security or network concerns."
"The price has room for improvement."
 

Pricing and Cost Advice

Information not available
"Splunk APM is expensive."
"The product is a bit expensive considering the competition but the company may negotiate the price."
"The pricing is reasonable."
"This is an expensive solution."
"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."
"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 offers a 14-day free trial and after that, we have to pay but the cost is reasonable."
"It appears to be expensive compared to competitors."
