HY
Senior System Administrator at Interactive Group
Monitoring solution provides comprehensive visibility across IT infrastructure
The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.

Provides deep packet visibility for tracing failed transactions and helps improve enterprise-level monitoring
Many improvements are needed for Riverbed NPM+, particularly in NetIM, which does not perform as well as SolarWinds' single module NPM solution. Additionally, within Riverbed Portal, there is an Application Map module that could be improved. It can show the application's architecture and connectivity to the network. The applications map feature needs enhancements for better customization since currently, it is quite limited. The enhancements I recommend are not for the entire Riverbed product suite, but specifically for the application map feature within the Portal of Riverbed NPM+. This Portal is one of the dashboard modules and while there is potential for improvement, it must be enhanced significantly to provide better functionality. Currently, you cannot trace by transaction number alone; knowing the source and destination IP is necessary. For instance, if I transfer money and a transaction fails, tracing that transaction ID is not captured in AppResponse. I have raised this concern, and if this feature is implemented, it would greatly benefit banking customers, especially because it is not available with their competitors either.

Quotes from Members

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

Pros

"I would rate the overall solution ten points out of ten."
"You should really try Nagios; it will help a lot and I have found that it is the best buddy for system admins."
"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."
"We use the product to monitor server applications."
"Nagios allows IT staff and end-users to see the status of critical services on the network and can alert and notify selected users if critical services fail, reducing the mean time to recover."
"This is a fit for purpose product which means that if you have a definite list of requirements and are not willing, or unable, to spend money on big enterprise tools, then Nagios is a tool to go to."
"We are using Nagios Core on a VM and it's working very well, even though the specs of the VM are very low because it doesn't require much storage."
"Inspite of this limitation it is a fantastic product to use at zero cost"
"Alluvio Network Performance Management is good for troubleshooting."
"Riverbed NPM+ provides a holistic view of the network and deeper insights into traffic and packet analysis."
 

Cons

"We're using the free version, which limits us in terms of the things that we can do. If we had the paid version, a lot of our issues would probably go away. For example, we can't isolate instances that are being built or updated with the production ones. When they're being built, on Nagios, they're showing in red. It'd be nice to be able to partition those off until they're all green, and then we can bring them into the environment. This is probably because we've got the free version and not the paid version. If we went for the paid version, it would probably allow us to do exactly what we want to or remove the restrictions that we have, but if we are able to isolate instances in the free version, it would make life much easier."
"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
"Nagios' great customizability is also one of its greatest drawback."
"Nagios SLA. I'm currently working on Nagios Digger, which has many code-level problems."
"It would be nice if it was hosted in cloud. Also, they need to improve the graphs."
"They should simplify the features so it becomes easier to setup out of the box."
"The initial setup process could be easier."
"Many improvements are needed for Riverbed NPM+, particularly in NetIM, which does not perform as well as SolarWinds' single module NPM solution."
"Currently, you cannot trace by transaction number alone; knowing the source and destination IP is necessary."
 

Pricing and Cost Advice

"The enterprise version has technical support. The version we are using is free."
"It's free."

"We are using the free version."

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