Sentiment score
7.1
Datadog's customer service is responsive and knowledgeable, though some users report delays with complex queries and phone support.
Sentiment score
6.8
Zabbix users praise supportive documentation, community forums, and responsive technical support despite occasional time zone challenges and free version reliance.
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.
In recent years, due to business expansion, knowledge levels among support engineers seem to vary.
It is so straightforward that I have never had to use the support.
 

Scalability Issues

Sentiment score
7.7
Amazon CloudWatch is praised for its scalability, managing large workloads effortlessly and adapting to diverse performance monitoring needs.
Sentiment score
7.6
Datadog efficiently scales with cloud services, offering seamless expansion, though users highlight the importance of monitoring pricing.
Sentiment score
6.9
Zabbix is highly scalable, excels in diverse environments, but large deployments may require database optimization for efficient performance.
Amazon CloudWatch's scalability is managed by AWS.
Zabbix has high scalability.
Zabbix is very scalable and lightweight.
I would rate its scalability ten out of ten.
 

Stability Issues

Sentiment score
8.1
Amazon CloudWatch is reliable and stable, though users experience occasional logging delays and minor complexities in query customization.
Sentiment score
8.0
Datadog offers reliable and stable performance with minimal downtime, impressive uptime, and efficient monitoring, even during peak periods.
Sentiment score
7.5
Zabbix is reliable and resource-efficient, performing well with database tuning and handling heavy workloads without crashing.
I sometimes notice slowness when Amazon CloudWatch agents are installed on machines with less capacity, causing me to use other monitoring tools.
Zabbix is very scalable and lightweight.
Zabbix is quite stable, and we haven't had any problems with Zabbix itself.
 

Room For Improvement

Amazon CloudWatch needs enhancements in customization, log management, pricing, integrations, data visibility, and user interface for better performance.
Datadog needs improved performance, interface simplification, clearer billing, better integration, customization, analytics, documentation, security, and mobile app integration.
Zabbix users seek improved UI, automation, integration, and customization with enhanced reporting, security, and scalability for non-technical users.
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.
In future updates, I would like to see AI features included in Datadog for monitoring AI spend and usage to make the product more versatile and appealing for the customer.
The documentation is adequate, but team members coming into a project could benefit from more guided, interactive tutorials, ideally leveraging real-world data.
There should be a clearer view of the expenses.
The only issue I can note is that it's Linux-based, and Linux documentation is not the best.
 

Setup Cost

Amazon CloudWatch pricing is usage-based, often cost-effective, but may increase with data use and custom metrics.
Datadog offers flexible pricing based on usage and organization size, with potential for high costs if not monitored closely.
Zabbix is cost-effective and flexible, offering open-source monitoring with no licensing fees, low expenses, and optional support costs.
Overall, the pricing of Amazon CloudWatch is very expensive.
Amazon CloudWatch charges more for custom metrics as well as for changes in the timeline.
The setup cost for Datadog is more than $100.
 

Valuable Features

Amazon CloudWatch offers metrics, alerts, automation, and analytics with seamless AWS integration, scalability, and third-party service support.
Datadog offers intuitive, comprehensive monitoring and integrations, enhancing infrastructure and application management with real-time insights and efficient operations.
Zabbix is valued for open-source customization, scalability, comprehensive monitoring, alerting systems, and cost-effective enterprise IT management.
Being an inbuilt solution from AWS, it saves time on installation, setup, and maintenance.
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.
I like its filtering capability and its ability to give the cyber engine insights.
Our architecture is written in several languages, and one area where Datadog particularly shines is in providing first-class support for a multitude of programming languages.
The technology itself is generally very useful.
If disk usage surpasses a threshold, say 70%, I receive alerts and can take proactive action.
Zabbix is Linux-based open-source software, and the main use case is to reduce costs.
Zabbix has a lot of features, including monitoring, status updates, and collecting information telemetry from storages and servers as well.

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…

Single pane of glass, easy to share dashboards, and good for monitoring
We've had some issues where we had Datadog automatically turned on in AWS regions that we weren't using, which incurred a small but steady cost that amounted to tens of thousands of dollars spent over a few weeks. I wish there was a global setting that lets an admin restrict which regions DD is turned on in as a default setup step. Sometimes, the APM service dashboard link isn't sharable. I click something in the service catalog, and on that service's APM default view, I try to share a link to that with a teammate, and they reach a blank or error screen. I wish there was more organization and detail in the suggestions when I use the query editor. I'm never quite sure when the autofill dropdown shows up if I'm seeing some custom tag or some default property, so I have to know exactly what I'm looking for in order to build a chart. It's hard to navigate and explore using the query autofill suggestions without knowing exactly what tag to look for. It's been a bit hard to understand how data gets sampled or how many data points a particular dashboard value is using. We've had questions over the RUM metrics that we see and we had to ask for help with how values are calculated, bin sizes, etc to get confidence in our data.

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
