Sulesh PK - PeerSpot reviewer
Monitoring and Operations Pilot at Egis S.A.
Experience enhanced monitoring with real-time alerts and efficient support
I would like to see automation in the poller features, as currently, the poller is not automated. If we could automate the addition or removal of hosts in the poller, it would improve efficiency. Sometimes, Centreon does not show the status of services as updated, which should be addressed. Additionally, enhancements are needed in identifying configuration issues, providing real-time alerts in case of issues, and improving the HTTP configuration tasks, as Centreon does not currently display issues with HTTP links, requiring manual investigation.

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.
