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…
Syarul Idzuddin Adzmi - PeerSpot reviewer
A scalable and affordable tool for monitoring data centers
Five engineers are needed for the maintenance of the product. I would definitely recommend the solution to those planning to use it. To increase the rating for the product, Nagios should offer remote support and offer more customization in reporting while making it easy for the customers to use it. Overall, I rate the solution an eight out of ten.

Quotes from Members

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

Pros

"What I found most valuable in Amazon CloudWatch is that it gives you detailed information, which I found helpful because it can even provide you with data for the past one minute, which is quite granular. That was what helped me most in terms of finding the root causes. Task automation is another valuable feature of Amazon CloudWatch."
"CloudWatch immediately hooks up and connects to the KPIs and all the metrics."
"The tool's UI is good. One can scroll through the logs very easily."
"Monitoring time and ensuring ease in it is the most valuable feature."
"The tool enables live monitoring."
"The most valuable part is the metrics part, which is really good."
"It's a very simple logging system."
"The solution effectively monitors golden signals like CPU, page requests, and queues."
"One of the most valuable features is the dashboard because the UI was effective and easy to use. The alert systems are good as well. We had no failovers and had high availability. We can search the queries fast as well in Nagios Log Server."
"A great feature of the solution involves its internal portal."
"The product is scalable."
"The initial setup of Nagios Log Server was easy and straightforward."
 

Cons

"The product’s documentation must be improved."
"It would be beneficial for CloudWatch to provide an API interface and some kind of custom configuration."
"For monitoring applications or for APM, CloudWatch has some limitations. You cannot monitor application performance from CloudWatch, and you have to go for a third-party tool."
"Amazon CloudWatch's pricing needs improvement."
"Right now, in relation to monitoring services, there are too many services and too many metrics per service."
"I think something that can be improved are the alerts and alerting mechanism based on no rejects. We want to have it more flexible and that is one of the key things that is required."
"Adding conditional expressions would enhance its functionality."
"CloudWatch doesn’t monitor disk throughput by default."
"As we are talking about a product which is open to the public, the pricing makes it challenging for us to profit off of its marketing."
"The customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
"The configurations during initial setup could be improved. If they could be agentless, as in the case of the Ansible product, it would be better. I would like to be able to analyze the network bandwidth."
"The support could be better."
 

Pricing and Cost Advice

"The price of Amazon CloudWatch is reasonable. When the rate of data collection is done the price will increase. The price is less than other solutions."
"The price is okay for me."
"It’s an open-source solution."
"The pricing model is pay-as-you-go so you have to be mindful of usage to manage costs."
"The pricing is average."
"We have monthly licensing costs. The licenses are probably in the vicinity of about $300 - $350/month."
"The tool is not expensive."
"The product's cost is relatively inexpensive."
"For a single instance, the price is around $4,000."
"On a scale of one to ten, where one is expensive, and ten is cheap, I rate the pricing an eight or nine."
"We found the pricing to be quite affordable."
