New project - XenAdminQt - a cross-platform GNU/Linux, macOS, Windows native thick client
-
@Tristis-Oris There are many features missing since it's alpha now, but you can open bug tracker request on github if you want to keep track of progress for this particular feature.
-
@benapetr
Consider making a PR to https://github.com/xcp-ng/xcp-ng-org (https://github.com/xcp-ng/xcp-ng-org/blob/master/docs/management/management.md) if you want to make your project more visible. -
@TeddyAstie good idea, thanks, I will do it once I get close to releasing first non-alpha version, right now it's still too immature for production use (although latest master version is so good and stable I already use it to manage most of my own clusters)
-
Note we already gave visibility on this project twice, with the last 2 XO blog post release and newsletter
-
@olivierlambert ok that's great, I didn't even notice, thanks!

I just released 0.0.4! Still an alpha, but it's becoming pretty usable - there was over 60 commits of code cleanup, polish and also limited testing of all visible features - pretty much everything that is now visible in the UI should be operational at this point, option pages, properties of hosts, pools, VDIs, configuration of NICs, even bonding and advanced stuff like pool password / secret rotation. All XAPI actions and commands were already ported over from C# variant, so my focus now is only on finishing it into a final usable product.
We also have some features that original client doesn't have (such as XenCache explorer)!
Next on my to-do is to add all features that are currently missing completely: HA, GPU, PCIe, VM import / export etc.
Note: I will not be porting over any licensed or proprietary Citrix stuff. This tool may work with XenServer just fine, but I will not be porting over any of the proprietary features, because I will never use it and I have no way to test it either.

Version 0.0.5 alpha was just released.
Tree view got major fix - it's now almost fully on-par with the C# version, all logic and missing icons and context menus were fixed.
This is rather a quality of life release, from features only GPU support was added, rest were only bug fixes, but a lot of them. XenAdmin is now so stable now I am even using it on my production servers. It already feels same (even better in some aspects) as the C# version.
I also added some new minor feature - all table views now support export to CSV via context menu (into clipboard), very handy if you need to export data from various views.
-
@benapetr you seem gifted with app development.
do you know RV Tools ? https://www.dell.com/support/kbdoc/en-us/000325532/rvtools-4-7-1-installer
this tool is pretty handy when auditing VMWARE infrastructures, it can connect to vcenter or directly to ESXi and full dump in csv/xlsx the infrastructure configuration (all aspects of the config, be it VM, hosts, networks, datastores, files, ...)
I could see a real production use of same tool, but for XCP Pools/XCP hosts
would be a great add to XenAdmin !
-
@Pilow I know them a little bit, I will have a look, but I am now working on another new cool thing! It's called xen_exporter: https://github.com/benapetr/xen_exporter
It's a prometheus exporter that hooks directly to xen kernel via xenctrl library from dom0 and extract all low-level metrics from the host, allowing very detailed graphs with very low granularity with stuff I always missed in both XenOrchestra and XenAdmin:
Detailed information about the host, every single CPU core utilization, load, avg. load, current frequency, P-state, C-state etc., number of active Xen domains, memory utilization etc. etc. here is example from a host with 80 logical CPUs (older 2 socket ProLiant G9 I have in my lab):

Minor downside is that this is an extra daemon that needs to be installed on dom0 to expose those diagnostic metrics, but it's written in go (I followed original node_exporter which is also in go) with cgo linking to xenctrl library - it's extremely fast (almost 0 CPU overhead) and uses very little RAM (13MB), but I think it's going to be brilliant tool for low level extremely detailed per-host performance metrics in the future.
Note: There is already a similar project also called xen_exporter, but that one is for me architecturally inacceptable because it's just a wrapper around xapi's rrdd endpoint - same stuff that XenAdmin and Xen Orchestra already uses for its limited graphs, it has to run on 3rd VM (which is probably "cleaner" than running anything on dom0), but needs to connect to xapi using root credentials over HTTPS endpoint and scrape the data from its rrdd endpoint, which is less efficient and much less granular, and probably only works via active master node, so configuring that exporter in prometheus is tricky.
Edit: had to trim that output, too much text for the forum

anyway I release most of my personal tools for XCP-ng as open source, so if I ever find a need for anything like rvtools and would start such a project (if nobody else does) I would also publish it as open source.

@benapetr said in New project - XenAdminQt - a cross-platform GNU/Linux, macOS, Windows native thick client:
@Pilow I know them a little bit, I will have a look, but I am now working on another new cool thing! It's called xen_exporter: https://github.com/benapetr/xen_exporter
It's a prometheus exporter that hooks directly to xen kernel via xenctrl library from dom0 and extract all low-level metrics from the host, allowing very detailed graphs with very low granularity with stuff I always missed in both XenOrchestra and XenAdmin:
...
We have a similar project : https://github.com/xcp-ng/xcp-metrics, but unfortunately it's not used as of today (though it could get revived as Rust for Xen matures, i.e easier to build).
There is also Xen Orchestra OpenMetrics support but it's not on XCP-ng itself.
