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

"The alarms are one thing I love about AWS CloudWatch. It has alerts that notify us when resource use is approaching the limit."
"Monitoring time and ensuring ease in it is the most valuable feature."
"We use Amazon CloudWatch for logging."
"The most valuable feature of Amazon CloudWatch is intrusion prevention."
"The monitoring features are valuable."
"The most valuable features of Amazon CloudWatch are metrics, dashboards, alarms, logs, events, logs insight, and application insights."
"The most valuable feature of Amazon CloudWatch is collecting the logs from Lambda."
"It offers direct integrations with various storage providers, making it convenient to push logs from CloudWatch to these external platforms."
"The initial setup of Nagios Log Server was easy and straightforward."
"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."
"The product is scalable."
"A great feature of the solution involves its internal portal."
 

Cons

"The product’s documentation must be improved."
"We'd like the interface to be as easy as Datadog."
"The solution should provide human-readable metrics."
"There is room for improvement in terms of stability."
"The drill-down aspect on the dashboard of the solution needs improvement. We get a very good high-level overview, but when we drill down, it becomes a little less clear. We have given this feedback to AWS as well and hope they will improve this in the future."
"The solution's pricing is a bit higher."
"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."
"The solution's auto-scaling could be improved."
"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 customization and dashboards have shortcomings and need to be improved to make the tool look more presentable."
"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 support could be better."
 

Pricing and Cost Advice

"It is a free-of-charge service."
"Amazon CloudWatch has very cheap pricing, and it hardly costs my company $25-$30 a month for fifty systems, so it's pretty affordable."
"The price of Amazon CloudWatch is reasonable for detailed basic monitoring."
"The pricing can be considered reasonable, especially when already operating on a cloud platform."
"The product's cost is relatively inexpensive."
"It’s an open-source solution."
"Its pricing is reasonable. It is sometimes tricky, but it is reasonable as compared to others."
"We have monthly licensing costs. The licenses are probably in the vicinity of about $300 - $350/month."
"We found the pricing to be quite affordable."
"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."
