Aids significantly in the threat-hunting process and provides a score-based evaluation of user experience

There are many valuable features, but understanding end-user response times stands out. It provides a score-based evaluation of user experience, helping customers quickly pinpoint whether issues originate from the network, server, client, or application. Additionally, it facilitates in-depth analysis of application dependencies. The retrospective network analysis capability of Observer GigaStor has been beneficial. It's a pivotal feature for network performance solutions. However, I prefer to consider the entire solution suite - GigaStor, along with GigaFlow and Apex - for comprehensive network visibility and monitoring. So, I prefer to integrate all three solutions to provide the best visibility. They complement each other well, with Apex aggregating and correlating data from both GigaStor and GigaFlow to enhance environmental understanding and troubleshooting efficiency.

Alerting precision has reduced incident response times and improved department-level network visibility

The auto-pause sensor during the maintenance window is good without any false alerts, and it prevents me from getting flooded with alerts during planned maintenance, helping department heads understand their own network usage better. It has reduced incident response time by giving clearer ownership of each alert, ensuring alerts go to the proper recipient. SNMP testers and auto-pause are among the best features of PRTG Network Monitor, which is particularly useful for different departments such as HR and finance, where alerts can be filtered accordingly. The alerting features and dashboard of PRTG Network Monitor are very helpful, especially in our industry. However, the dashboard can look cluttered on smaller screens, which is one negative aspect. PRTG Network Monitor has impacted us positively; we have stopped getting flooded with alerts during planned maintenance or unplanned outages. Compared to others, this gives specific alerts very quickly and helps department heads understand their own network usage better, thus reducing incident response time so that each alert has clear ownership.

Quotes from Members

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

Pros

"This solution allows us to see exactly what is going on in the network and we can very quickly solve issues with users."

"I also have the ability to see an application's performance, to see what's going on, why a network is slow, why this program for this user is experiencing a delay or some network issue"

"I have no regrets using this product, I am very satisfied for what I paid for it and for the things I am able to do with the product."

"The ability to capture packets. It is not only for monitoring. That is very important for a company that wants to keep an eye on the packets, the transactions, the flows..."

"There are many valuable features, but understanding end-user response times stands out. It provides a score-based evaluation of user experience, helping customers quickly pinpoint whether issues originate from the network, server, client, or application. Additionally, it facilitates in-depth analysis of application dependencies."

"Industry-leading line rates, packet-capture technology and data-mining capabilities are the most valuable features."

"This solution allows us to see exactly what is going on in the network and we can very quickly solve issues with users."

More Observer GigaStor pros

"As far as network monitoring and analysis, I cannot think of a more intuitive and flexible product on the market today."

"This solution provides us with the needed feedback on our IT infrastructure. It allows us to grab all the information from a single point of view."

"There was only one feature I liked about PRTG Network Monitor a lot, and that was bandwidth monitoring, though, in the newer versions of the tool, that feature is now a bit lacking. Pricing for PRTG Network Monitor is also not as expensive. It's a good tool, even for beginners."

Cons

"The interface is pretty complex, so for the average user, it takes a while to get up to speed with it. I would like it to be more user-friendly."

"Maybe the graphical user interface could be simplified to allow people to use it more easily."

"GigaStor feeds into Apex. So, the area where there could be improvement would be in artificial intelligence. For example, the incorporation of more advanced machine learning or AI capabilities could enhance its functionality."

"Graphics need improvement. Because a lot of the information there you have to input first in some case to have full potential. It could be more automated."

"There are some issues, in our environment that puts processing restraints on the Gigastor when turning on trending data to be sent to APEX."

"I would like to have more than 4TB of storage available in the portable version of this solution."

"The Observer Console UI is consistent and stable, but could use some updating to be more modern."

"I would like to have more than 4TB of storage available in the portable version of this solution."

More Observer GigaStor cons

"Sometimes, it is difficult to drill down further to get information, e.g., if we saw spike in traffic, then we would want to drill down and find out what is causing that spike in traffic."

"The reporting features look very technical and that can be improved."

"PRTG Network Monitor can improve by having better integration with devices."

"The licensing policy needs more flexibility."

"PRTG Network Monitor could improve interaction with customers by offering direct support involvement instead of just mail responses."

"There seems to be a big jump from the basic scan to the really thorough scan. There is a big jump in the quantity of sensors it uses for certain things. One minute you might get ten and then the next you get 200. There seems to be a big jump between the two at times."

"PRTG Network Monitor should provide syslog monitoring since it is not available at this time. There are very limited features as compared to other solutions."

"The technical support response time is still prolonged, and the resolution can be better."

More PRTG Network Monitor cons
