Application performance and System monitoring at Agos

A reasonably priced tool for system and application monitoring

The main room for improvement is in the solution's presentation and the integration area. In our company, we use the integration capabilities from ServiceNow. We also have another big monitoring solution in place in our company, which is Dynatrace. At the moment, there doesn't exist an out-of-the-box integration for Dynatrace. I think that the integration and the exporting of the data collected are areas where Checkmk lacks but should try to improve the most. The only implementation of Checkmk that allows high availability is the virtual appliance that has the option for the availability of a different box. Otherwise, you have to find a way to implement it manually with some custom solution, which could be an improvement.

vCTO - Technical Account Manager at CMIT Princeton

An agent-based solution that monitors and manages various networks but lacks support

Once you've established the client in the RMM tool, you create the site. Setting up the site can be a bit onerous because of the recent changes, which we need to learn. However, once it's set up, deploying the agent is extremely simple and straightforward. It's as easy as using a URL that people can visit, which will automatically determine the environment and download the necessary components. The initial setup can be somewhat challenging. If it's a new site, it'll probably take me about an hour to set it up. It's a matter of getting familiar with the process. As far as deploying the agents to the individual endpoints is concerned, that's literally minutes. Customers can do that themselves. A few of us can do set up the initial site. Anyone can handle the agents deployment. In our case, it's quite doable even by sending the URL to the customer.

Quotes from Members

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

Pros

"The most valuable feature of the solution is that it has a lot of different pieces, and they all work together...It is a very scalable solution. Scalability-wise, I rate the solution a ten out of ten."

"Checkmk was built on a platform that was user-friendly, and I could build my charts easily."

"Checkmk helps me compare data and foresee issues."

"The initial setup of Checkmk was easy...It is a very stable solution."

"Overall, from one to ten, I rate Checkmk a nine."

"We can monitor multiple sites using the product."

"I really like the auto-discovery feature."

"The alerting system in Checkmk really works properly."

More Checkmk pros

"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."

"The most valuable feature is the patching solution."

"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."

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

"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."

Cons

"In Checkmk, the documentation can probably be improved a bit more."

"If an alert is generated for a specific pattern in the log, and if Checkmk catches that log, it will stay there even after the alert is resolved."

"It is easy for tech-savvy people, but newcomers might find it intimidating."

"The initial setup is a bit complex."

"Checkmk does not allow running scripts at varying intervals."

"The main challenge for us is that we're moving from Nagios to Checkmk, and we're still getting used to the new way of working."

"Sometimes we receive alerts, and it can become annoying when you acknowledge an alert. It is very clunky when you acknowledge the alert. The process is not very intuitive, and there are instances where it feels a bit cumbersome to acknowledge an alert."

"Checkmk does not work too easily with the PowerStore. I use a PowerShell script as Checkmk runs on Linux and a Windows system, connecting with the Checkmk agent."

More Checkmk 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."

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

"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."

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

"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."

"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."

Pricing and Cost Advice

"Checkmk is a fairly reasonably priced solution."

"The price of Checkmk is cheaper compared to other enterprise products."

"The product is affordable."

"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."
