Reporting features improve operational efficiency while weekend support needs enhancement

Support is moderate and needs improvement, especially during weekends when technicians perform upgrades. During weekends, they need to provide more support to ensure a smooth transition. There is a call for ManageEngine OpManager to scale better in automation and AI functionality. Although the product stability is good, support enhancement is necessary to enable better planning for upgrades and maintenance activities.

Flexible device polling times and extensible modules are key features for me

There are lots of reasons why I'm using it. The installer itself is basically something that can be used as a no-questions-asked type of installer. I can use it with automation tools like Chef and Puppet. I don't have to answer some random questions. I can worry about all that stuff later on in the configuration. It allows for variable polling times of devices on the network. Because it's all in text, in general, that obviously makes it easier from the automation perspective as well, to modify configuration on the fly, using Puppet and those kind of tools. It does have different modules, so you can extend the solution as you need it, or get as little as you need in the beginning, so you don't have to buy a full set of modules. You just buy what you need and expand later on.

Quotes from Members

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

Pros

"ManageEngine OpManager has many beneficial features that bring value to enterprises, allowing them to manage from 1,000 to 10,000 devices in one console, with multiple add-ons enhancing its utility, such as Firewall Analyzer, which optimizes rules and displays all rules in the firewall."

"Desktop central products feature dashboards that are neat and offer comprehensive information."

"The alerting feature has improved our organization. We can create multiple alerts and refine them to how we need to use them."

"Defining thresholds and other alerting criteria is fairly simple and would not require a lot of training. This is very useful if you are managing a large environment."

"Some of the useful features are NetFlow and analytics."

"I like being able to push configurations to multiple devices. If you have the same configurations for all the branches, it's easier to use ManageEngine OpManager and push configurations at once rather than individually pushing them to each device."

"The dashboard, versatility and larger horizon are valuable."

"The most valuable feature is the network-related reporting."

More ManageEngine OpManager pros

"The big thing is the event management engine, which is really, really nice to use, and it comes at a reasonable price, unlike some of the competitors like Netcool from IBM. Those kinds of tools are hugely expensive and they come as resource-heavy types of solutions. This obviously doesn't require as much hardware, but it does offer similar benefits where you can manage all the events."

"The installer itself is basically something that can be used as a no-questions-asked type of installer. I can use it with automation tools like Chef and Puppet. I don't have to answer some random questions. I can worry about all that stuff later on in the configuration."

"It does have different modules, so you can extend the solution as you need it, or get as little as you need in the beginning, so you don't have to buy a full set of modules. You just buy what you need and expand later on."

"In my case, I prefer to only poll interfaces that have descriptions, and the ones that don't have descriptions, I don't really want to know about them. It does allow for all these bits and pieces and adjustments, and fine tuning to get it to a point where it works for my needs."

"It allows for variable polling times of devices on the network. Because it's all in text, in general, that obviously makes it easier from the automation perspective as well, to modify configuration on the fly, using Puppet and those kind of tools."

Cons

"ManageEngine OpManager can improve by having better updates for critical issues."

"OpManager is slow but that just might be the server we have it on. I don't think that's the problem but I don't do the server. But it is slow. When you're interacting with it, it could be more nimble and could be faster."

"For the implementation part, I am facing issues when configuring the business view."

"You cannot resolve 100 percent of the issues yourself. You would need to reach out to the support. It needs to be cheaper."

"The solution is a bit difficult to configure. There are quite a number of configurations and plugins that you must handle early in the process."

"We had some stability issues at the outset that have since been resolved."

"They should add more features to URL monitoring."

"We encounter challenges in monitoring cloud services. I would also appreciate it if there was someone available to walk you through the documentation."

More ManageEngine OpManager cons

"These kinds of solutions are more node- or device-based solutions. It would be nice in the future if they could be more data-oriented, so it would be easier for me to pull different stats based on ad-hoc requirements; but in a big, centralized database where I can pull specific things, and mix and match the way I want to."

Pricing and Cost Advice

"ManageEngine OpManager is cheaper than SolarWinds."

"We had perpetual licenses. The cost was around 36,000 for OPManager, and then you'd have the yearly maintenance fee of 2,000 or 3,000."

"I rate the tool's pricing an eight out of ten."

"The price for ManageEngine OpManager is average."

"The solution is highly affordable"

"The solution's licensing costs are yearly and based on the number of applications."

"The initial cost is low and the add-ons are reasonable."

"ManageEngine OpManager has a three-tier licensing model."
