Nagios XI vs. Proxmox VE

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.

We used Proxmox to implement private cloud services, for clusters
of a small number of servers, from 3 to 11 with and without high
availability. Allways with ZFS file systems, and we used to install the
root pool in SSDs mirrored and use other pools with RAID 10 in groups of
four, for the virtual machines and containers, for the backups and snapshots, we used magnetic disks with RAID 10, in groups of four. Do
not use an even number of servers because does not facilitates the
implementation of High Availability, because the corosync service must
have an odd number of servers to detect a failed server for the quorum
system. We used a variety of servers, from clone PCs with AMD Ryzen with 6 cores and 12 threads with 64 GB of RAM no ECC, to high end servers with 64 cores and 128 threads per cpu and 2 cpus per server, with AMD EPYC Rome or Milan, 2 terabytes of RAM ECC.

• BackUp System, provides extensive propiertes and verifications. An exclusive server for BackUp Administration (PBS)
• Hardware Customization. You can select several properties to adapt the hardware to your needs
• Easy administration. You will be able to manage the server with easily accessible tools such as the web console and usage statistics.
• Certificates Administration.

• 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• Overall lack of new developments, making this product more and more outdated.

• The web UI does not work as well on mobile devices. It is useable, but a mobile optimised / responsive UI would be nice to have. There is a mobile app, so that may alleviate this issue, but I have not yet tried it.
• Support in the community forums could be better. There are paid support plans, but new users trying out the software will not have access to this. Answers to questions can sometimes be terse, and I can imagine this may put some people off.
• The wiki is a bit hit and miss with certain topics. I've often seen outdated or missing information, and the whole thing looks like it could do with some polish. I'd love to see it opened up for the community to add to.

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.

The interface is easy to use for most of it, but still lacks screens for some configurations. Also, a few of the screens are not as intuitive as they could be. This is specially true with disk and network configuration, where some graphic/visual representations of the configurations would be very useful

Proxmox VE's ha-cluster functionality is very much improved, though does have a not-very-often occurrence of failure. In a 2-node cluster of Proxmox VE, HA can fail causing an instance that is supposed to migrate between the two nodes stop and fail until manually recovered through the command-line tools provided. Other than this, the HA clustering capability of Proxmox VE has proven to be reliable in 3 or more clustered environments with much less chance of these failures to occur.

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.

Proxmox VE is cheaper than VMware, especially upscaling an HA architecture. Compared with other free or less expensive solutions, Proxmox VE is high compatible with more types of hardware solutions and more VM types. From my point of view, Proxmox VE has no competitor at the same price level, it offers the most complete and production-ready HA solution.

Proxmox VE provides everything you need to quickly add new storage mediums, network and local, as well as networking interfaces, such as using Linux standard bridges and now Open-vSwitch bridges which can be even more scalable than before. Proxmox VE 4.0 dropped support for OpenVZ in favor of the more well supported and native LXC and made an upgrade path to it very simple.
