Automated monitoring has streamlined time tracking and project management across all clients

I think the most valuable feature of ConnectWise RMM is scheduling my time with clients and capturing my times with them. Time management is key for my workflow. It helps with keeping track of all our clients and all the devices, so ConnectWise RMM has been quite helpful in managing my IT environment overall. Automated patch management in ConnectWise RMM has made everything streamlined, allowing me to concentrate on more important tasks. I can run my automations and ensure that they go through every server, every cloud infrastructure, and every client. I've observed that with ConnectWise RMM, capturing my times used to be quite an issue when working with overseas countries, but now it's much easier, and I can monitor everything I'm doing in real-time.

A suitable choice for unified and efficient infrastructure monitoring across diverse environments providing user-friendly GUI, cost-effectiveness, and versatility

We use it for this specific client, they've deployed multiple instances of it across various locations to facilitate monitoring. To effectively monitor their infrastructure, it seems necessary to implement additional monitoring solutions for all three types of devices they have Nagios Fusion…

Quotes from Members

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

Pros

"The user interface is the first valuable feature. The integration is the second valuable feature. The integration that you are doing with the products needs to be very certain. There shouldn't be any glitches. There are different software out there that will give you an option called scripting and ask you to do a hundred different things to set up a script for a particular customer. With Continuum, everything is done a single way. You just select the clients, script, and machine, and then you just go and deploy. The best part of Continuum is that it is not just a software company. It is a pure services company. It is an RMM software; it isn't used as a PSA. The software is just a part of the service offering. This is the difference between all other service providers out there and Continuum. Continuum is basically providing services. Continuum doesn't sell the software."

"The technical support has been fantastic."

"The most valuable feature is the patching solution."

"It enables us to respond to issues quickly and efficiently."

"The best features of ConnectWise RMM are the automation tools that they've included, which are quite good, enabling us to mass manage systems, schedule scripts, etc."

"Automated patch management in ConnectWise RMM has made everything streamlined, allowing me to concentrate on more important tasks."

"My advice for others looking into using ConnectWise RMM is that it is the best tool to work with in terms of RMM, and I do not know why people prefer NinjaOne; I clearly prefer ConnectWise much more."

"The most valuable features are RMM and patch management. However, the main reason we have been using this solution is that they are the only provider of RMM that has an outsourced NOC and help desk. This has been very useful."

More ConnectWise RMM pros

"Being open source lets us customize it for our monitoring needs, saving us money."

"It is easier for client installation, and the configurations are doable even for a newcomer in the field."

"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."

"It's very easy to manage and monitor it."

Cons

"It's a legacy tool with many outdated approaches. It is managed offshore which affects everyone because it seems the developers don't fully understand our needs."

"I would like to see the incorporation of the dashboards for other products that they work with into the main dashboard."

"The initial setup with ConnectWise RMM is painful, to be completely honest. The pain points during the initial setup with ConnectWise RMM include the migration from Automate to RMM being very time-consuming and the process not being as straightforward as indicated."

"They can include support for vaulting, where you can actually document the entire infrastructure, including servers, desktops, networks, passwords, maps, diagrams, and customer information. Continuum has integrated everything, and you have to use a PSA. Continuum has a ticketing system and an RMM. They could integrate the functionality for IT documentation. An MSP would want everything into one tool."

"ConnectWise RMM sometimes has a lag, and the speed can be an issue."

"If a computer hasn't been turned on for a long time and the client software is installed, it may not reconnect to the dashboard once it's powered up."

"The solution could improve by offering better overall management and dashboards."

"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."

"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."

"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."

"There are some bugs, although not that many. There are some situations where the solution is not stable but the number of problems is not very high."

Pricing and Cost Advice

"It has a pay-as-you-go model. They don't have any minimum, maximum, or such sorts of commitments with any of their partners or customers. I don't believe they have any restrictions about using a specific number of agents. You don't have to use 100 agents or 200 agents to work with this. They have a lock-in period of three months, during which you cannot switch a service plan, which is fine."

"The licensing works such that the more you add, the more it costs, but for the most part, the price starts at about $5 USD per client."

"Continuum Command price is more expensive than competitors, it is three times the price of the next lowest and costs approximately $25 an endpoint. However, when you take that into account you receive the help desk and outsource NOC included it has a lot more value because competitors do not provide the outsourced NOC and help desk."

"The pricing is quite reasonable, especially when compared to the broader market."
