Nagios XI vs. VMware vCenter

If anyone looking for the monitoring system for the infrastructure this is the go-to tool which monitors all infrastructure related components from server health to Networking and update us with mails and can be easily integrated with multiple other tools as needed for example PagerDuty , Also this suits good both on premises and cloud environments as well. If we are managing complex environment this tool for monitoring is best one.

The VMware vCenter server is very useful in maintaining the CPU/RAM/datastore resources are balanced when there are multiple ESX/ESXi host servers. It is clear what resources are being used, and it is easy to migrate VMs to different ESX/ESXi hosts. Being able to remotely connect to the VM servers in vCenter when you cannot have other remote connections helps in maintenance and troubleshooting.

• VSAN storage management and redundancy - high performance IO with built in fault tolerance across the cluster, not reliant on a single hardware item
• VM fault tolerance. The ability to relocate a running VM and restart VMs from failed or isolated nodes
• Resource management and alerting. Tracking load across physical systems and allowing us to rebalance for better utilisation

• Robust, but visually old interface. Requires a lot of work to become presentable.
• Small selection of dashlets to construct new views.
• No MS Azure monitoring ability, nothing for “as service,” very limited Amazon cloud monitoring abilities.
• Questionable price politics (could make it a lot less for developing markets to actually increase use of the product and R&D budgets).
• No report designers nor the ability to create new reports. No changes in this area for years.
• Overall lack of new developments, making this product more and more outdated.

• Currently, the HTML 5-based vSphere Client lets you manage the essential functions of vSphere from any browser, however, it would be nice if they would port all management functions over to the HTML 5-based Client.
• Performing updates and upgrades to the infrastructure is a bit challenging for someone that may not be as intimate with vSphere. I think the updates/upgrades should be more integrated into the UI and provide the ability to push to the hosts, etc...
• It would also be nice to have a more robust snapshot management tool to prevent snapshot overgrowth. It would be nice to be able to set a lifespan for the snapshot(s)

We are very dependent on this software, it has become a much needed tool to perform the daily tasks that are required to maintain the virtual server environment. VMware has become very pricey over the years, so we are looking for alternatives for cost savings strategy, but nothing has been found to be on par to what we are currently using

We
are using Nagios XI in our organization primarily for monitoring all our
application servers and databases, this is helping us in addressing all the
infrastructure issues in advance by alerting us when it any server hits the
threshold as per the initial parameter setup also it has free tier which helps for small scale applications monitoring to save some expenses.

I work with vCenter for 10+ years and i love it. I can find my way around and can help building and expanding the platform. It is easy to use and there are a lot good communities for the extra support when needed. Even the Homelab community is of great value.

VMware support has always been fantastic and they have been invaluable in solving tougher issues that have been run into. Most of the time, any oddities encountered are fixed by available updates. This can be deduced by support quickly with logs within vCenter. We have not run into something yet that support was unable to help with. They either have a solution already, or they are able to find one quickly.

Since moving away from the Windows Server hosting the vCenter application and instead using a virtual appliance, it has become much easier to implement and deploy the new versions. We can easily create a snapshot or clone of the vCenter vApp to ensure any problems encountered during the upgrade can be mitigated with a fall back to the old version to prevent unscheduled downtime.

Cost efficiency is the main reason which we opted [for] Nagios as we were previously using IDERA tool with comprehensive database monitoring solutions, but the slow performance we are getting while monitoring the instance of the database.

Citrix Xen Server.... Great Hypervisor but very limited in terms of functionality

MS Hyper-V... [VMware vCenter Server] is better for almost everything and appliance form makes a clear winner for security and ease of deployment

• The positive impact of vcenter is definitely felt in larger organisations in terms of being able to manage multiple servers all in one environment
• It will decrease the amount of time your server engineers will have to spend in the server room or datacenter.
