Currently, we are not using OP5 Monitor because our license expired. The last time we worked with OP5 Monitor was in May this year, approximately two to three months ago. Alerts in OP5 Monitor are effective, and alerting is straightforward from the tool. We can adjust the alerting intervals and integrate with any alerting tool, such as ServiceNow, which will create tickets automatically. From OP5 Monitor, we can receive email alerts or SMS alerts to our mobile numbers. It is easy to integrate OP5 Monitor using Slack-based integration or directly using the REST APIs. Automation in OP5 Monitor is available for alerting, which is useful for customers and users. I can recommend OP5 Monitor as it is a good product. On a scale of 1-10, I rate OP5 Monitor a 9.
I would recommend this solution to others. It is a highly capable solution. I rate OP5 Monitor a ten out of ten. The solution has received a lot of positive feedback, and it is an excellent tool for monitoring. Despite the broad range of monitoring capabilities, it's relatively simple to manage, and adding checks for new technologies is a breeze. They provide pre-built checks for cloud servers, on-prem servers, and various other checks. Therefore, it's effortless to deploy and use.

I rate the solution an eight out of ten. Regarding advice, the graphic user interface is much better than Nagios. So if someone knows the basics of Nagios, they can use OP5 Monitor efficiently if there are any difficulties.

I like the flexibility, as it is based on Nagios. It is more tailored towards network monitoring and I can recommend it. There are some visual aspects and the NetFlow that are missing, but otherwise, I'm completely fine with it. Especially with the API, where I can use the data with many other systems, it's great. OP5 is meeting my purpose, but the UI is not suitable for management, who are looking for something fancy. Also considering the NetFlow functionality is missing, it loses a couple of marks. I would rate this solution a nine out of ten.
Make sure that you have a good relationship with ITRS or a partner that can support you in the process. Most of the clients that I work with have been our clients for many years. The reason they are using ITRS is that it's something that works for them. They invested a lot of time and effort into learning the tool, adopting it to their needs, and making sure that it's working well for them. I also think they value the local contact, that they have someone to talk to; a vendor that actually supports them in their endeavors. Stuff happens. It doesn't matter if you run a small IT department or a large one, or if you just buy IT services from an external company, stuff never works 100 percent. When it stops working, it's important that you know so that you can take action, tell your customers, start taking preventive actions, and try to fix the problem. That's what this tool provides you: knowledge about whether things are working or not. If you don't have something like this, what's going to happen is that people are going to get upset and, sooner or later, someone will be so upset that they pick up the phone and call you. And you will have another 60 people who are upset, but who haven't called you because they're busy with other things. This is something you need to have, to stay on top.
