Customer Service

Sentiment score
6.1
Azure Monitor's customer service is praised for responsiveness, especially with premium support, but can improve on general knowledge and speed.
Sentiment score
7.1
Splunk Observability Cloud generally receives positive customer support reviews, citing prompt, knowledgeable assistance, despite occasional resolution delays.
However, the second-line support is good.
Snr. Infrastructure Architect (Data Centre) at LogicEra
Users end up getting no resolution from their team because they're outsourced vendors, and they don't have deeper expertise over any of the products they are referring to.
Software Engineer (DevOps/ SRE) at Sensys LLC
I would rate the support for Azure Monitor as a seven.
Cloud Solution Architect at Cloudzant
On a scale of 1 to 10, the customer service and technical support deserve a 10.
Systems Administrator at a insurance company with 1,001-5,000 employees
They have consistently helped us resolve any issues we've encountered.
Software Engineer at UKG
They often require multiple questions, with five or six emails to get a response.
Splunk Observability Expert
 

Scalability Issues

Sentiment score
7.8
Azure Monitor provides scalable solutions for businesses, supports auto-scaling, integrates with tools, but requires careful cost management.
Sentiment score
7.3
Splunk Observability Cloud scales efficiently with organization needs, though costly, offering flexible integration and handling large deployments seamlessly.
With APM, you can go heavy or you can go light. It just depends on what you want, what your use case is, and how reactive you want to be to system load or resilient to failure.
Consultant at a outsourcing company with 201-500 employees
Azure Monitor is very scalable; there are no issues with scalability for different kinds of businesses.
Cloud Solution Architect at Cloudzant
We've used the solution across more than 250 people, including engineers.
Splunk Observability Expert
As we are a growing company transitioning all our applications to the cloud, and with the increasing number of cloud-native applications, Splunk Observability Cloud will help us achieve digital resiliency and reduce our mean time to resolution.
Application Developer at UMB Financial
I would rate its scalability a nine out of ten.
Senior Manager at a financial services firm with 10,001+ employees
 

Stability Issues

Sentiment score
8.3
Azure Monitor is highly stable and reliable, though less agile, with high user ratings and potential cost concerns.
Sentiment score
7.7
Splunk Observability Cloud is praised for stability and reliability, with occasional performance issues managed effectively by support.
Azure Monitor is working fine, yet I face a costing issue as if there are a lot of logs collected in the workspace or in the center, it becomes very costly.
Snr. Infrastructure Architect (Data Centre) at LogicEra
I would rate its stability a nine out of ten.
Head of DevOps at a tech services company with 1-10 employees
We rarely have problems accessing the dashboard or the page.
Splunk Observability Expert
Unlike NetScout or regular agents for APM, RUM has many problems during the POC phase because customer environments vary widely.
General Manager at MOCOMSYS
 

Room For Improvement

Azure Monitor struggles with user-friendliness, integration, complexity, multi-cloud support, proactive monitoring, and requires enhanced usability and cost transparency.
Splunk Observability Cloud needs better integration, automation, user interface, Azure support, and enhanced log analysis for improved user experience.
If Azure Monitor can independently add one gigabyte, two gigabytes, or five gigabytes at least to log storage, I can fix the logs without syncing with Log Analytics Workspace and Sentinel.
Snr. Infrastructure Architect (Data Centre) at LogicEra
The cost skyrockets once you start using it, and there are complaints that the actual cost of the Kubernetes cluster was less than the cost they were incurring for Azure Monitor.
Software Engineer (DevOps/ SRE) at Sensys LLC
The challenges with Azure Monitor are that it's initially complex to set up because you need multiple components.
Cloud Solution Architect at Cloudzant
The out-of-the-box customizable dashboards in Splunk Observability Cloud are very effective in showcasing IT performance to business leaders.
IT Operations Engineer at ABC Supply Co. Inc.
The next release of Splunk Observability Cloud should include a feature that makes it so that when looking at charts and dashboards, and also looking at one environment regardless of the product feature that you're in, APM, infrastructure, RUM, the environment that is chosen in the first location when you sign into Splunk Observability Cloud needs to stay persistent all the way through.
Systems Monitoring Engineer II at a government with 10,001+ employees
There is room for improvement in the alerting system, which is complicated and has less documentation available.
Head of DevOps at a tech services company with 1-10 employees
 

Setup Cost

Azure Monitor offers cost-effective variable pricing, but careful management is essential to avoid high expenses for enterprise users.
Enterprise users see Splunk Observability Cloud as costly but valued for features, though some explore alternatives due to expenses.
When I export logs into the application, workspace, log analytic workspace, and into Sentinel to read reports, I need to add storage, which increases the cost.
Snr. Infrastructure Architect (Data Centre) at LogicEra
Splunk is a bit expensive since it charges based on the indexing rate of data.
Senior Manager at a financial services firm with 10,001+ employees
It is expensive, especially when there are other vendors that offer something similar for much cheaper.
Solutions Architect at Ikusi
It appears to be expensive compared to competitors.
Head of DevOps at a tech services company with 1-10 employees
 

Valuable Features

Azure Monitor provides comprehensive real-time monitoring, alerting, and analytics, enhancing security and scalability for seamless infrastructure management.
Splunk Observability Cloud offers real-time monitoring, data integration, and APM with machine learning for scalable, user-friendly performance insights.
The alerting features definitely help in reducing operational downtime for my customers by allowing us to get notifications in advance and take active actions.
Cloud Solution Architect at Cloudzant
I also appreciate the ability to measure feature activity, see what types of devices they are on, follow specific use cases, and measure the amount of traffic going to a particular application.
Consultant at a outsourcing company with 201-500 employees
Resource monitoring is essential.
Snr. Infrastructure Architect (Data Centre) at LogicEra
Splunk provides advanced notifications of roadblocks in the application, which helps us to improve and avoid impacts during high-volume days.

Andy Rabern - PeerSpot reviewer
Consultant at a outsourcing company with 201-500 employees
Telemetry insights have improved how I track user behavior and application performance daily
I feel Azure Monitor does a fair job. I do feel it is not a streaming service in my opinion. There are advantages to having stream messaging and logging on that level. But for what it is, I feel it does well. My perspective is more based on an Application Insights agent running on a service or an app service and sending the telemetry via the agent, and also doing the filtering of telemetry at the agent level so you are not having a ton of telemetry. I believe Azure Monitor does pretty much the same thing. I have also used tools such as New Relic, and New Relic is a much more robust tool, but that is a different product and you are going to pay for that. It is a different offering altogether. The subscription that we had at the time allowed for a couple gigabytes of telemetry during the month, and I believe that telemetry only lives for about two months. You have to experiment with it to see how much you want to pay. I was not really involved in the pricing. It was more along the lines of we were running up against our limits in terms of the amount of free telemetry or telemetry that we get with our subscription, and so we either needed to scale back or turn specific telemetry types off or do some more sampling. It is nice that those capabilities are there so that you can reduce the amount of telemetry. I cannot really speak to pricing but I do believe that it is somewhat reasonable for Azure Monitor. New Relic is pretty expensive, I believe.

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.
