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

"It's actually easier to collaborate since it is already deployed in the AWS cloud itself."

"In case there is a failure, Elastic manages everything well, and there no major downtime."

"Our customers have seen tangible benefits from Amazon OpenSearch Service, especially in terms of their applications running smoothly, so they do get a return on investment."

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

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

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

"AWS has now made our life easy."

"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"

More Amazon OpenSearch Service pros

"Stability is where they shine. It has been super stable. We have high-end monitoring for our data centers. We monitor all kinds of metrics in our two data centers. We monitor maybe over 2,500 checks, and the product that has been successful and always alerting us is Pandora."

"Pandora's architecture is interesting; it's open so you can easily extend and enhance it, it's simpler to customize Pandora compared to other solutions, and it's also scalable enough to support large environments."

"Thanks to its flexibility, I have been able to adapt the tool to our servers and find out quickly how their console works."

"You can configure several types of architecture for high availability or load balancing."

"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."

"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."

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

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

More Pandora FMS pros

Cons

"One improvement I would like to see is support for auto-scaling."

"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 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."

"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."

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

"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."

"I would say that, basically, the configuration part is an area with a shortcoming...Some upgradation is required on the configuration side so that we can get to use it."

"It would be beneficial to have some level of customization available in the managed service, tailored to the specific use cases of the end users."

More Amazon OpenSearch Service cons

"It would be useful if Pandora FMS included an ISO image (or «software appliance») for each big company that leases virtual private machines (VPS), just like in AWS."

"I would like to have a dashboard with all assets displayed, with a quick hover-over status."

"Pandora FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."

"They can also do more refinement in end-user usability because not everyone is strong technically, and people who aren't strong technically might be averse to the product, even though it has come a long way."

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

"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."

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

"I find that this software is resource heavy, and demands a lot of processing capacity."

Pricing and Cost Advice

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

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

"You only pay for what you use."

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

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

"You get the license and it includes updates, new versions, and access to the complete library of modules."

"They are very competitive on the pricing side. That's one reason why my manager keeps using it."

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

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

"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."

"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."

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