Data Center Real-User Monitoring (DCRUM), discontinued vs. Nagios Core

Dynatrace Network Application Monitoring (NAM), formerly DCRUM, has improved greatly compared to when it was DCRUM; however, it still needs a lot of improvement in end-to-end flow capture with regards to network monitoring. Its alerting and integration capabilities are very good and easy to use. But it still needs a lot of tweaking in usability.

Nagios monitoring is well suited for any mission critical application that requires per/second (or minute) monitoring. This would probably include even a shuttle launch. As Nagios was built around Linux, most (85%) plugins are Linux based, therefore its more suitable for a Linux environment.

As Nagios (and dependent components) requires complex configurations & compilations, an experienced Linux engineer would be needed to install all relevant components.

Any company that has hundreds (or thousands) of servers & services to monitor would require a stable monitoring solution like Nagios. I have seen Nagios used in extremely mediocre ways, but the core power lies when its fully configured with all remaining open-source components (i.e. MySQL, Grafana, NRDP etc). Nagios in the hands of an experienced Linux engineer can transform the organizations monitoring by taking preventative measures before a disaster strikes.

• Dynatrace DCRUM can monitor legacy application protocols that are still used in a lot of organizations worldwide who still trust in those technologies.
• DCRUM monitors client-server architectures very well and can pinpoint issues along an infrastructure stack.
• Dynatrace DCRUM can analyze a wide spectre of protocols: Corba, DNS, DB2, Exchange, TCP, HTTP, IBM MQ, Citrix, ICMP, Informix, Tuxedo, SMB, LDAP, MSRPC, MySQL, NetFlow, Net8, Oracle Forms, RMI, SAP GUI, SAP HANA, SAP RFC, SMB, SOAP, XML.

• Monitoring of services is one of the biggest benefits for our company. Being able to respond in a timely fashion keeps business smooth.
• Hardware and device monitoring are easy to set up with proper parameters.
• Notification to key staff to be able to respond quickly makes issues go away faster.

• Major upgrades process is sometimes unpredictable.
• The use of SQL Server should be evaluated for something else.
• Easier SSL key handling.

• Nagios could use core improvements in HA, though, Nagios itself recommends monitoring itself with just another Nagios installation, which has worked fine for us. Given its stability, and this work-around, a minor need.
• Nagios could also use improvements, feature wise, to the web gui. There is a lot in Nagios XI which I felt were almost excluded intentionally from the core project. Given the core functionality, a minor need. We have moved admin facing alerts to appear as though they originate from a different service to make interacting with alerts more practical.

We're currently looking to combine a bunch of our network montioring solutions into a single platform. Running multiple unique solutions for monitoring, data collection, compliance reporting etc has become a lot to manage.

Best of breed.

The Nagios UI is in need of a complete overhaul. Nice graphics and trendy fonts are easy on the eyes, but the menu system is dated, the lack of built in graphing support is confusing, and the learning curve for a new user is too steep.

The only thing missing for a 10, would be if they texted or called you back.

I haven't had to use support very often, but when I have, it has been effective in helping to accomplish our goals. Since Nagios has been very popular for a long time, there is also a very large user base from which to learn from and help you get your questions answered.

Nagios can't trace real user transactions from a front-end tier through a backend-tier,;with Nagios you only can monitor server availability and hardware issues. Riverbed is commonly used to determine networking issues without considering real user transactions impact on an application stack.

Because we get all we required in Nagios [Core] and for npm, we have to do lots of configuration as it is not as easy as Comair to Nagios [Core]. On npm UI, there is lots of data, so we are not able to track exact data for analysis, which is why we use Nagios [Core].

• Dynatrace Network Application Monitoring (NAM), formerly DCRUM, helped us get a lot of info on an ongoing issue.
• It helped us figure out network bottlenecks in our environment.
• It is a very costly tool and a lot of other cheaper tools give same kind of info.

• With it being a free tool, there is no cost associated with it, so it's very valuable to an organization to get something that is so great and widely used for free.
• You can set up as many alerts as you want without incurring any fees.
