IBM Rational ClearCase might be better suited for a smaller / simpler code base. Larger code bases really slow it down... but then again there are better alternatives out there for source control
Manage Engine OpManager is better suited to serve server and network admins at organization to monitor their servers and network devices. It helps us with compliance with the reports available like utilization reports and capacity planning reports. It helps you to keep track of what all process are consuming the resources. It helps you in monitoring what is happening in your switches, routers and firewall
Rational ClearCase is excellent for handling versioning and branching. No other tool I've used has the depth that ClearCase has when it comes to handling complex branching scenarios and identifying where certain versions of particular files are within a particular configuration.
Rational ClearCase handles parallel development of many dependent applications really well.
The use of ClearCase Views to switch between projects and configurations is extremely convenient as opposed to the local workstation model of the competitors.
It measures the CPU utilization of hosts, the network bandwidth utilization of links, and other aspects of the operation
It often sends messages—sometimes called watchdog messages—over the network to each host to verify if it is responsive to requests.
Set Up Notifications And Reports.
OpManager offers a set of advantages that allow it to adapt to the needs of the company, guaranteeing effective monitoring of the application networks used in our organization.
Alerts has to be configured correctly otherwise unnecessary bombarding of alerts can cause inconvenience.
The server on which ManageEngine OpManager is to be deployed should have higher resources as monitoring a large number of devices may slow down the performance of the system.
Configuring the advanced features may require a learning curve.
The rating I provided is based on the product quality, experience (I have been using OpManager for almost the last 4 years), and relevance of the information/response I generated through Manage Engine OpManager. I have also received good support from OpManager.
At first, we were not able to add our Avaya switches to the configuration backup module, our partner tried to help, but they did not find the solution, we had one remote session with tech support of ME and they solve the problem.
If development is centrallized to one location and your company releases hundreds of customized versions of your software per year, then ClearCase is the best tool for managing the complexity of multiple versions of customized software. If your company has globally distributed development, then I'd recommend Team Foundation Server over ClearCase. If your organization uses Agile Methodologies, then I'd recommend TFS with GIT.
During our competitive analysis, we found ManageEngine OpManager was not expensive compared to other vendors. At the same time, there was no compromise on the features such as customized reporting or configuring alerts per our clientele's unique requirements. These are our client words "Other vendors ask us to pay more $$$ for enabling additional email alerts".
I don't know if you can calculate ROI with a monitoring solution, there are more factors to calculate.
We found a really big problem with a network switch (faulty transceiver) in a trunk configuration with OPManager. this caused us serial troubles with the overall network stability.
We are loosing around € 3.000 to 5.000 per hour if our network is not working so this was a great help to fix this issue
Our label printers are really important to monitoring in our warehouse system, this makes OPManager a great solution for that
