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.

Scans servers and network devices through SNMP and reduces manual maintenance for our infrastructure team

I like how ServiceNow Discovery scans servers and network devices through SNMP. Most fields on our forms are auto-filled, reducing manual maintenance for our infrastructure team. Post Discovery implementation there is hardly any maintenance. There are three to four fields that are customized. Otherwise, 90% of the data is auto-filled. Discovery can also run in bulk, which is helpful for organizations that cannot run it during weekdays. With identification rules, if a configuration item (CI) isn't in the CMDB, you can simply add the IP address, and it will be automatically added based on criteria like name or serial number, making CMDB maintenance easier.

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."

"The most valuable features of Checkmk are its resource monitoring, infra monitoring, and log factor configuration."

"I really like the auto-discovery feature."

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

"The alerting system in Checkmk really works properly."

"We can monitor multiple sites using the product."

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

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

More Checkmk pros

"We mostly use the solution's ITSM and ITOM capabilities in most workflows."

"It's pretty robust, and it's agentless for the most part. So, you don't need to deploy agents, which makes it a lot easier to stand up."

"The workflows are beneficial as they allow tasks to be assigned to respective teams without the need for coding."

"The product provides great scalability features."

"Stability-wise, I feel it is a good product."

"This solution provides excellent insights."

"The best part about ServiceNow Discovery is that it is included in the ServiceNow suite."

"ServiceNow Discovery works better than other products I've used."

More ServiceNow Discovery pros

Cons

"The initial setup is a bit complex."

"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."

"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 allow running scripts at varying intervals."

"I think that the integration and the exporting of the data collected are areas where Checkmk lacks but should try to improve the most."

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

"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."

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

More Checkmk cons

"Debugging is a bit tough in ServiceNow Discovery, so debugging should be made very easy."

"The product could improve some of the visualization and architecture setups."

"What needs improvement in ServiceNow Discovery is the reporting UI because I didn't find it as friendly compared to other tools. Other tools have better reporting UI than what's currently in ServiceNow Discovery. What I'd like to see in the next release of ServiceNow Discovery is more user-friendly out-of-the-box reporting that would be helpful for non-technical users. Some users such as managers would want to just do a few clicks to access the reports and shouldn't be required to do search queries, but right now, reporting in the tool isn't very user-friendly."

"We would like more flexibility with the licensing. Discovery is bundled with ServiceNow's ITOM license. It was more affordable when it was sold separately, but we bought a package license to get more functionality out of the CMDB. We'd prefer to buy only the pieces we need instead of taking things we don't want or solutions that aren't yet mature enough to use."

"It creates quite a bit of duplication, so that needs to be fixed."

"It's an expensive platform."

"Without improvement in the patters, applications can't be discovered"

"In future releases, I would like to see more AI-oriented enhancements in the solution. It would automate most of the things that we have to do manually write the scripts and go on the teleservice, what to do. So if we have something in place and if we can train the module, then AI would be a good thing."

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."

"There is a subscription for ServiceNow Discovery. It's expensive, but I think it's one of the best solutions on the market, so it's worth it."

"It's on a yearly basis. We renew our contract for three years at a time."

"The solution is not inexpensive so pricing is rated a three out of ten."

"You need a subscription to ServiceNow Discovery, so you can use its features. You can also use specific plugins with the tool, and some of the plugins are free. I don't have information on how much my company pays for the subscription to ServiceNow Discovery."

"I would rate the product's pricing a six out of ten. We had availed some discount from the standard pricing. Even then, the tool's pricing is expensive. You have to pay some vendor service fees for the product's implementation."

"If the product is not deployed properly, it can be very expensive."

"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."

"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."

Overview

Checkmk is a powerful tool for monitoring IT infrastructure, providing vital insights on servers, databases, network devices, and custom applications.

Custom monitoring: Enhances MySQL performance tracking.
Slack integration: Provides immediate downtime alerts.
Graphical trend analysis: Offers 400 days of trend data.
Multiple site monitoring: Ensures seamless data synchronization through task automation.
Resource and infrastructure monitoring: Configures log factors to fit budget constraints.

Checkmk is deployed extensively in large enterprise environments for monitoring critical infrastructure.
