Event tracking has become smoother and data analytics provide clear insights for user actions

Amazon OpenSearch Service is not providing the processing feature directly. From Amazon OpenSearch Service, we are actually maintaining the AWS SQS, the queue service, which is responsible for providing information about what data has to be modified. So using that SQS, we're actually providing it, but we're not directly using Amazon OpenSearch Service for keeping data to other data pipeline thing. So far we didn't use it for any machine learning purposes, but in future, we have plans to extend or implement this feature. Since AWS itself is secure and Amazon OpenSearch Service is a part of this entire ecosystem, it becomes much easier for security purposes. From the validation point of view, Amazon OpenSearch Service itself provides easy to communicate APIs and up-to-date documents, which is much beneficial. For example, if I'm missing anything, I can directly go and check the documentation. That is actually much easier. I would rate it as really good so far. It's much faster. For our local machine, we can also use a kind of replica of Amazon OpenSearch Service just for development purposes. That is another good feature. I would say for the encryption thing and also the user access control management, it's much faster. For some of these hashing algorithms, it also worked really well so far. To be honest, I didn't find any places where it can be improved. However, I think they could provide more abstraction. For example, still for searching, we have to write down the queries in a specific manner, such as for a specific JSON structure or in a specific way. Otherwise, they don't provide us the actual results. For at least this purpose, I think abstraction could be a bit easier or a bit improved. Other than that, right now there is the age of AI, so some kind of prompting could also work, but I'm not sure how it could be integrated. As a user, lower prices or reasonable pricing is always better. Those can be improved as well. However, it is good that most of the services including Amazon OpenSearch Service actually provide pay as you go pricing. So if there were a bit lower version or a bit less payment methodology, it might be much better.

The open architecture is easy to extend and enhance

Pandora could deliver better analytics out of the box. You can work around these limitations with the help of other tools like Grafana. The shortcomings are mostly on the graphical side. The built-in report generators are a bit limited in some areas. They could improve their management console's ability to monitor large environments could be improved. For example, SNMP management is only partially integrated into the management console.

Quotes from Members

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

Pros

"I would definitely recommend Amazon OpenSearch Service to other professionals due to its fast and reliable search capabilities."

"The initial set up is very easy...We really appreciate Amazon!"

"The business analytics capabilities are the most important feature it provides."

"It's a good log management platform. In terms of infrastructure management, it's good."

"We retrieve historical data with just a click of a button to move it from cold to hot or warm because it's already stored in the backend storage"

"It enables us to efficiently search and retrieve our event data, offering us a versatile approach to locate specific information within these logs."

"The customer service is excellent, rated nine out of ten."

"They have the good documentation in the help text and that is the reason the Amazon Elasticsearch is the perfect solution for the current market."

More Amazon OpenSearch Service pros

"The most valuable features are auto-discovery and automatic detection of the network topology and network monitoring."

"This product has allowed us to identify and correct certain issues that were affecting our solution."

"We are consultants and thanks to Pandora can detect a lot of disasters that other companies can't, and we can offer high availability of the system to the client."

"Features I have found most valuable with Pandora are the personalized metrics and the simplicity of data."

"The official forum is active enough to answer most of the high-end technical questions that you may have."

"It is easy to create your own custom modules if you just know a little bit of scripting. If you have unique requirements, you can just make your own modules. You can even grab checks from other vendors. There are open-source checks for various things such as SMTP, etc. There is a long list of different ones from Nagios. You can just use them, and within seconds, you get yourself a check that is monitoring whatever you need. It is really flexible. I guess that's why they call it Pandora Flexible Monitoring System (FMS). It is reliable. It does the job, and it alerts. It is also surprisingly feature-rich. Our network guy just recently asked about a particular protocol to monitor the bandwidth on the network, which is not a common protocol. When I looked it up, and I found that they cover it. It is very mature for a not-so-known product."

"I like this solution a lot because it has a very large Hispanic community and the platform looks very friendly."

"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."

Cons

"The configuration should be more straightforward because we had to select a lot of things."

"There is a problem with the database. Amazon only provides the hosting to run our applications bias, but there is no option to manage the database within the Elasticsearch product."

"The pricing aspect is a concern. The service is way too costly. For the past month, I used only 30 to 40 MB of data, and the cost was $500. AWS could improve pricing."

"I want to see a new feature in Amazon Elasticsearch Service that allows users to create default filters for filtered levels."

"There is the problem with the database. Amazon only provides the host to run to our applications bias, but there is no option to manage the database within the Elasticsearch product."

"Amazon Elasticsearch can improve the bullion in the near search and the ease of integration with Kibana. Additionally, there could be more flexibility in the configuration and documentation."

"The configuration should be more straightforward because we had to select a lot of things."

"We faced documentation challenges during integration after migrating from Elasticsearch to Amazon OpenSearch Service. Better documentation on integration, query handling, and a more user-friendly UI could enhance the product."

More Amazon OpenSearch Service cons

"We would like the real-time monitoring of an interface to be improved within this solution."

"Pandora could deliver better analytics out of the box."

"An update to the Android app would be appreciated."

"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."

"Pandora FMS is relatively new, and the interface with the older version crashes at times. We have several different operating systems, such as Linux and Windows, and Pandora does not run as well in these."

"Third-party integration should be improved for some commonly used products such as Universal CMDB."

"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."

"A nice feature in the next release would be an automation module to run workflow actions."

More Pandora FMS cons

Pricing and Cost Advice

"You only pay for what you use."

"The solution is not expensive, but priced averagely, I will say."

"Compared to other cloud platforms, it is manageable and not very expensive."

"There is a community edition available and the price of the commercial offering is reasonable."

"You have to pay for the number of agents and models that you are monitoring. I would rate the cost at three with one being the most expensive and five being the cheapest."

"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."

"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."

"In terms of money, the Enterprise version is the cheapest that I have found after a market study."

"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."

"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."

"Pandora FMS is easy to implement and the pricing of licenses is competitive."

"My rule of thumb would be that if you need more than thirty agents, and you lack an automation tool such as Chef or Puppet, you will save a lot of time and money going to the Enterprise edition."
