Senior System Engineer at Omgea Exim Ltd
Provides real-time monitoring and exceptional technical support
As a reseller, I think HP iLO can be improved in a few ways. HP has a lot of experience with iLO, but they need to work on synchronization between iLO and the system hardware. Sometimes when the system fails, iLO doesn't get the proper information from the system, so there's a need for improvement so it can provide real-time information for our engineers to give the correct solutions to customers. The only room for improvement I see is synchronization with the current hardware and socket because sometimes hardware fails, but the information is delayed on iLO. There are points of view where iLO logs and some logs are missing from the system, which prevents our engineers from finding the correct solution. We need to inform HP to improve their hardware part for better synchronization to ensure all the necessary information fills up properly in the logs.

Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.

Quotes from Members

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

Pros

"HPE Integrated Lights Out (iLO) has the best features for detecting any kind of hardware failure, such as any DIMM, HDD, system board, or PSU failures, providing real-time alarms with all necessary information."
"HPE Integrated Lights Out (iLO) is user-friendly, offering easy navigation and a nice GUI."
"The overall performance of the product is superb."
"Nagios XI is a simple monitoring tool with performance management and everything a standard monitoring tool provides."
"Simplicity of configuration; I can set up configuration of 100 devices with about 10 services in one to two days."
"The solution's most valuable feature is its simplicity."
"The most valuable feature is the monitoring of processes."
"For anyone who is interested in using this solution, I would recommend it."
"The integration with the alerting software, automated maintenance windows, and the ability to set up templates and groups of checks, as well as customize the checks themselves, are very valuable features."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
 

Cons

"Sometimes when the system fails, iLO doesn't get the proper information from the system, so there's a need for improvement so it can provide real-time information for our engineers to give the correct solutions to customers."
"I am currently avoiding HPE in my current build because of the pricing that is almost highway robbery. Service contracts are required to receive firmware updates."
"The important separation between Interface and Core to maintain historical plugins and methods generate complexity that makes Nagios unusable for repeat work."
"The Configuration Wizard needs improvement, because not all vendors are present."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough. You need to read some tutorials or be trained to understand what it's displaying. Also, I think it needs more features to improve network visibility because there are some things you can't detect."
"Its simple deployment but complexity comes once you have to import more plugins."
"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box. But in the end, you learn to live with it."
"Nagios provides most of the features by default, however to add more services to it, it requires additional plugins which require little effort on administrative end."
"The product does not have SAP monitoring."

"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"Nagios XI is open source."
"As it is not an agentless tool, I think it is expensive."
"The pricing is high with separate licensing for the product and support."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
