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

"Monitoring is the most valuable feature of this solution."

"The tool is useful for SNMP monitoring."

"The features we found most valuable in ManageEngine OpManager are the probe server and reporting because they're pretty good features."

"The solution is scalable."

"ManageEngine OpManager is user-friendly and easy to use. Additionally, useful for basic monitoring."

"I liked Network Configuration Manager. They had some pretty decent features there, and they also had pretty good monitoring and alerts."

"We don't have to keep an eye on it; it has a good automation option, which keeps us informed. It gives very less false positives. Overall, a really great product."

"The most valuable feature is the monitoring alerts. The administrators are immediately notified and can do the required action immediately. This is the feature we value and use the most."

More ManageEngine OpManager pros

"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."

"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."

"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."

"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."

"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

"There are certain things that are not possible to do with Op Manager. It's a solution that still needs time to develop."

"With regard to configurations, however, it would be nice to have more documentation on SNMP configurations. For example, if I want to add a new vendor, it would be great if ManageEngine provided the requirements for that vendor, such as the commands needed."

"There should be an option to get mobile notifications or SMS mirror notifications for critical issues. That way, when we don't have access to email, we can still receive notifications via our phones."

"The two views into the system are very good but could be extended to further customization to fit the need of end users in a variety of roles."

"If you have a ton of devices, it might slow down a bit."

"The main area for improvement for ManageEngine OpManager is its performance."

"The initial setup is a bit complicated. It needs a technician who is very aware of the flow and how to officially set up the flow chart, etc."

"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."

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

"The tool's licensing costs are yearly."

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

"ManageEngine OpManager is cheaper than SolarWinds."

"The solution is highly affordable"

"The solution's pricing is very low compared to other products."

"The licensing costs depend on the number of devices and accounts that are being monitored by the solution."

"We have a standard license for ManageEngine OpManager. We purchased the license for one year and now we are upgrading it soon."

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