Valuable reporting and alert system with room for PDF export improvements

The NetEase reporting structure needs improvement, especially the availability report, which is weak. It should be generated automatically with minimal human intervention and should be exportable as a PDF. Besides that, an integrated PDF export feature for reports is necessary. Also, the alert mechanism and graphing mechanism need to be integrated properly into Nagios Core. Currently, integrating these requires advanced Linux knowledge. Integration of more visualization tools like Grafana and Prometheus for better graphing and visualization is also recommended.

Detects suden changes but significant pricing concerns affect the effectiveness of network traffic troubleshooting

We use PRTG Network Monitor for monitoring traffic on interfaces and the behavior of network traffic. If there are sudden changes in traffic or any configuration issues, we can sort them out using PRTG. It's very helpful for troubleshooting and monitoring traffic utilization on our interfaces…

Quotes from Members

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

Pros

"We mostly use Nagios Core to integrate with Python and Bash Script."

"The reporting structure and the feature set are valuable to me."

"Provides timely notifications."

"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."

"The notifications are definitely one of the most valuable features of Nagios Core. We know what to look for and what to expect when things are down."

"Nagios Core integrates with tools like Splunk, Datadog, or Dynatrace. It is usually used as a feed to provide more technical information about devices or hosts to another system."

"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."

"Nagios Core is very configurable. Whatever you want, you can do it."

More Nagios Core pros

"There is a simplicity to setting up the extra sensors. It's really easy for us to build infrastructure and start monitoring very quickly."

"The best feature is that it lets me know what is going on. I need to know if something has gone down, I need to know if something is running very slowly. PRTG tells me that."

"Good compilation of the system's information."

"The solution is easy to manage and the reports are very accurate."

"The Slack integration is fantastic, and I've actually found it to be very useful recently."

"From a network point of view, we can see the state of the network, as well as bandwidth usage and downtime."

"The email notifications are helpful, and the dashboards are user-friendly for people with little network monitoring knowledge."

"PRTG Network Monitor's best features are its flexibility, ease of implementation, user-friendliness, and intuitive interfaces."

More PRTG Network Monitor pros

Cons

"Making it a little easier to configure and set up from the start would help. There are multiple layers that you have to wade through to be able to set it up, to do it the right way, and to get it to do what you want it to do."

"The NetEase reporting structure needs improvement, especially the availability report, which is weak."

"The UI is a little outdated and graphics could be displayed in a better way."

"The dashboard and monitoring features could be improved."

"The user interface could be more interactive because it is pretty basic."

"The alerting mechanism in Nagios Core could be improved."

"The mapping is a little hard."

"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."

More Nagios Core cons

"Scalability is the only major sticking point for me. There is a recommended number of sensors, which is around 10,000 and we're double that... The only option we have to scale is to buy another core, which would be a separate, stand-alone instance..."

"Maybe in the future there will be room for improvement, but currently, there is nothing pressing that I can think of"

"The remote probes seem to be a little bit buggy at times. They just stop working or they say they can't communicate. What we tend to do to is install the remote app onto the servers that we use. That seems to clear it up."

"I would like to see them take their graphing tools and convert them into a collector so that we can point telemetry to them"

"In our organization, we encounter performance issues with our PRTG probe service. I saw documentation from the vendor or Paessler mentioning that there are limitations for WMI sensors. Other than that, we are okay with PRTG."

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

"I have an issue with DFS, distributed file services... there isn't one by default. Taking into account the difference between DFS and DFSR as well would be great."

"It would be nice if it gave us alerts via Gmail or SMS message."

More PRTG Network Monitor cons

Pricing and Cost Advice

"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."

"The product is cheaply priced."

"It's free."

"The solution is expensive."

"I would rate the solution's pricing an eight out of ten."

"We are using the free version."

"We are using the free version of Nagios Core."

"Nagios Core is a cheap solution."

More Nagios Core pricing and cost advice

"It's a cost-efficient tool."

"We are licensed for 2500 endpoints."

"We looked at PRTG and SolarWinds. From a cost side perspective, compared to PRTG, and from what you get back from it, PRTG was sort of a hands down the winner."

"Right now, the smallest sensor pack that they have is just a bit out of range for me, as a business. This kills me, as I need the product. Therefore, there is always a balance between needing to buy it or continuing their free version."

"The pricing for PRTG in our case is reasonable because we have a lot of applications to monitor within PRTG. It is not that expensive."

"The pricing is okay and it is cheaper than some competing products."

"While I am not the person who deals with pricing, I would say that we pay around 1000 pounds a year."

"If you're looking for a cost effective software I’d suggest this product."
