Splunk ITSI support is generally good, but experiences vary by company size and issue, with occasional delays reported.
While using their cloud and cloud resources, if you have an issue with CloudWatch, you must pay additional monthly fees to get time from dedicated tech support.

Sentiment score
7.9
Splunk ITSI offers high reliability and stability, especially in cloud deployments, with minor issues related to infrastructure and data consistency.
I sometimes notice slowness when Amazon CloudWatch agents are installed on machines with less capacity, causing me to use other monitoring tools.
The setup, however, must be done correctly as incorrect deployment can lead to issues.
 

Room For Improvement

Amazon CloudWatch needs enhancements in customization, log management, pricing, integrations, data visibility, and user interface for better performance.
Splunk ITSI needs better integration, user interface, predictive analytics, machine learning, real-time alerting, automated response, and user support.
When using third-party dashboards such as Kibana or Grafana and other visualization tools, there should be a way to feed CloudWatch's data and logging capabilities into these visualization tools.
Amazon CloudWatch charges extra for custom metrics, which is a significant disadvantage.
Maybe Amazon Web Services can improve by providing a library for CloudWatch with some useful features.
Splunk ITSI could benefit from including more features that other solutions support, such as vulnerability management modules.
 

Setup Cost

Amazon CloudWatch pricing is usage-based, often cost-effective, but may increase with data use and custom metrics.
Splunk ITSI is a costly but comprehensive tool, valued for its observability despite complex licensing and high pricing.
Overall, the pricing of Amazon CloudWatch is very expensive.
Amazon CloudWatch charges more for custom metrics as well as for changes in the timeline.
Splunk ITSI tends to be more expensive compared to some open-source solutions.
 

Valuable Features

Amazon CloudWatch offers metrics, alerts, automation, and analytics with seamless AWS integration, scalability, and third-party service support.
Splunk IT Service Intelligence enhances incident management with agile data handling, advanced analytics, and effective troubleshooting features for quick issue resolution.
Being an inbuilt solution from AWS, it saves time on installation, setup, and maintenance.
I like its filtering capability and its ability to give the cyber engine insights.
The best features of Amazon CloudWatch need to improve visibility into the network because when using hundreds of network resources such as transit gateway, VPNs, routers, route tables, and firewalls, it does not give many details in a structured manner.
Splunk ITSI allows for integration with threat intelligence, enabling my organization to correlate more than two events for generating alerts.

Rahul Kundu - PeerSpot reviewer
Proactively address issues with seamless monitoring while enhancing custom metrics functionality
We use CloudWatch for monitoring and logging. It helps us monitor our applications' performance, particularly in ensuring that every API hit returns a response within four seconds, which is our SLA. We also monitor invocation errors in Lambda and use CloudWatch alerts to notify us of any issues…
Srinivasulu Soolluru - PeerSpot reviewer
It speeds up incident response by automating alerts and ticket creation
When configuring a dashboard, we can write search criteria. Based on the search criteria, the dashboard shows all the alerts, including the alert time, creation time, and a summary description of the alert. When you add an extra column, such as the user that triggered the alert, the next time he refreshes the dashboard, he wants to know that the alert is acknowledged. We want to improve that comment feature. In the Service Analyzer, we monitor the network infrastructure services and have a KPI for each service. When the value exceeds the threshold value, we can add the colors. For example, we can set it to green when the threshold value is within the limit. If it is red, then the value has passed the threshold. We want more colors in the service analyzer to display all these features.
