Utilizing data monitoring capabilities and scripting potential to optimize system management
I frequently program functions with PowerShell, and although Bash could be used, my specialization is in PowerShell. Two of us focus on programming in PowerShell for infrastructure optimization. I set up a dedicated server to run scripts every hour, generating files for Checkmk output. However, Checkmk does not allow running scripts at varying intervals. I am working on this in the raw version of Checkmk.

Cloud discovery has improved asset visibility and reporting but still needs smarter automation
The impact of ServiceNow Discovery on my organization's strategic planning depends on various factors. Some customers have their own discovery tools which they do not want to switch from, even if we explain why ServiceNow might be better, because they have been using them for a long time. Some customers are dynamic, so we need to have some kind of proposition that comes with ServiceNow. Sometimes, we need to talk with ServiceNow people themselves to give them a bundle offer in which we can have Discovery and ITSM at a much more affordable price than the competitors, so that is our main goal. Currently, I would say there might be a possibility if we can use some AI discovery features that could be helpful for our organization. If we can get discovery jobs running based on AI schedules, that would be beneficial. I believe in the coming future that I want to see myself working more with ServiceNow in this capacity.

Quotes from Members

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

Pros

"Overall, from one to ten, I rate Checkmk a nine."
"Checkmk helps me compare data and foresee issues."
"It's versatile, scalable, and easier to use compared to other solutions like Nagios and OMD."
"The most valuable features of Checkmk are its resource monitoring, infra monitoring, and log factor configuration."
"The alerting system in Checkmk really works properly."
"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."
"We can monitor multiple sites using the product."
"The initial setup of Checkmk was easy...It is a very stable solution."
"One of the most valuable features of ServiceNow Discovery is the automated discovery that helps identify dependencies and generates reports."
"ServiceNow Discovery provides significant benefits as an end-user tool by reducing the effort required to understand the estate environment."
"I would rate the stability of ServiceNow Discovery as nine, as we never had downtime."
"The initial setup is pretty easy."
"The product provides great scalability features."
"The service management and operations management modules are valuable."
"ServiceNow Discovery comes in a bundle with everything, including CMDB, which makes it much easier to use."
"When my team starting any project or learning a new environment, we always implement ServiceNow Discovery which can be used along with other products."
 

Cons

"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 initial setup is a bit complex."
"In Checkmk, the documentation can probably be improved a bit more."
"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."
"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."
"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."
"Checkmk does not allow running scripts at varying intervals."
"It is easy for tech-savvy people, but newcomers might find it intimidating."
"I cannot tie CMDB at this stage with strategic planning regarding ServiceNow Discovery ability to maintain accurate data in CMDB."
"Whenever you try to discover something with the solution, you get errors that are not descriptive enough."
"Instead of AI, even GenAI should be introduced in ServiceNow Discovery."
"The service mapping component is less developed than it is in other solutions, and is in need of improvement."
"I feel that credential-less discovery could be improved."
"The product could improve some of the visualization and architecture setups."
"Technical support has not been helpful when we have come across problems. They take too long to respond and then don't provide helpful information."
"I would rate technical support for ServiceNow Discovery as four. This rating is because there are features on the tool that never worked and despite calling our support, there were no results."
 

Pricing and Cost Advice

"Checkmk is a fairly reasonably priced solution."
"The product is affordable."
"The price of Checkmk is cheaper compared to other enterprise products."
"ServiceNow Discovery's licensing is not a very small investment, but it definitely pays off."
"It is an expensive product with a price that depends on the models that you wish to purchase."
"It is not recommended for smaller companies because of the price."
"It costs a lot. It is probably close to over a hundred thousand. It's an expensive platform, but you can't compare ServiceNow's Discovery functionality to other discovery tools. It's not an apples-to-apples comparison of ServiceNow to a configuration management tool to an asset management tool because it does those things, but it's not those things."
"It's a bit expensive compared to other products in the market, but it's worth the money you pay because it's far advanced in terms of features, automation, and capabilities compared to other products."
"As per a general discussion I had with the stakeholders, I figured out that it is a costly tool. There is a need to make additional payments apart from the licensing fees for better support services from ServiceNow."
"The product is not cheap."
"The solution is very expensive."
