Effective as a vector store, serverless architecture but there aren't enough security features
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. Even being serverless, it incurs charges during idle times. For just holding data, you need to create a list. AWS should add an option to make data idle, so it won't include computing charges. They charge for OCU units based on the time the serverless solution is up, not on indexing or retrieval speed. Once the service starts, it starts getting billed. It would help if there were an option to limit computing. When using it as a database, storing data without frequent fetching would save computing costs.

Personalized metrics; simplicity of data
My primary use case for Pandora is monitoring This solution has helped us improve our organization by allowing us to create a lot of metrics on several platforms, including Windows, Linux, and Unix. We then use these Pandora metrics to create an interface. We then pass the interface off to the…

Quotes from Members

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

Pros

"Amazon OpenSearch Service has enhanced our organization's ability to store and search large amounts of data efficiently."
"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"
"The customer service is excellent, rated nine out of ten."
"This service already sorts data like vectors. They have classified the storage pre-defined."
"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."
"Amazon OpenSearch Service provides a managed database solution, so we don't need to manage everything ourselves."
"The business analytics capabilities are the most important feature it provides."
"I would definitely recommend Amazon OpenSearch Service to other professionals due to its fast and reliable search capabilities."
"The administration of the console is very easy. I like that Pandora FMS is interactive and easy to manage."
"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."
"It allows me to quickly see the status of all of my printers, switches, computers, and virtual machines to determine if any system has fallen."
"You can configure several types of architecture for high availability or load balancing."
"Thanks to this software and to the work of the support team, we have everything under control."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
"The most valuable feature is that it is an all-in-one monitoring system."
"The monitoring system within this solution is very good. It is easy to use and navigate, and makes issue alarms easily viewable."
 

Cons

"In terms of data handling capabilities with Amazon OpenSearch Service, they can be complex and managing data in comparison to other SIM solutions is a major drawback, as it is very hard to handle the data."
"They can enhance data visualization."
"One improvement I would like to see is support for auto-scaling."
"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."
"One improvement I would like to see is support for auto-scaling."
"The price is fair yet leans towards the expensive side. I'd rate it five out of ten with respect to capabilities vs. cost."
"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."
"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."
"We would like the real-time monitoring of an interface to be improved within this solution."
"We would like to see improvement in the mainframe integration that this solution is capable of."
"This solution requires proper training to get 100% out of it."
"An update to the Android app would be appreciated."
"I find that this software is resource heavy, and demands a lot of processing capacity."
"The price for Pandora FMS is expensive."
"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 FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."
 

Pricing and Cost Advice

Information not available
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"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."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"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."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
