VMware vCenter and ESXi monitoring with Xymon

Question

We currently have a Windows vCenter for which I have written a few scripts for various monitoring with Xymon.

We are moving to a vCenter Appliance and I need to port these scripts (or write equivalent new scripts) to work on the vCenter and the ESXi hosts.

Can I get the Xymon client installed on an ESXi host (I suspect I need to add that as a plan after each upgrade too) or is there an alternative way?

I understand there are better monitoring solutions out there than Xymon, but we use this and migrating isn't an option right now.

I don't feel like pasting my script as an answer and URLs as answers are frowned so here it is in a comment. It uses SSH from the XYMon server via RSA Auth and PYVMOMI. https://www.freesoftwareservers.com/display/FREES/ESXi++6+-+Ram+-+CPU+-+Disk+Check+-+NTP+-+XYMon+-+Ubuntu — FreeSoftwareServers, Oct 30 '18 at 20:19
Have you been to my site in the past? I'm wondering if an old 301 is in your cache. Try a different browser as well, but thank you for letting me know! — FreeSoftwareServers, Oct 31 '18 at 02:30
I don't believe I have, but there is always a chance I have I guess — neildeadman, Oct 31 '18 at 06:10
OK, so i am getting "Could not connect to the specified host using the specified username and password" confirmed they are correct. — neildeadman, Oct 31 '18 at 15:40
That sounds like an ESXi SSH issue, can you SSH to the host from the CLI? Forget about the script until that's working. — FreeSoftwareServers, Oct 31 '18 at 19:05

There are plenty of options to get data out of vcenter for xymon.

You can not install xymon-clinet on esx, and must use scripts to get data via API / PowerCLI

xymon scripts and implementation stuff

Creators of pyVmomi :

See github

“pyVmomi is the Python SDK for the VMware vSphere API that allows you to manage ESX, ESXi, and vCenter.”

Creator of python-vmstats :

also github /python-vmstats

“Python script using pyVmomi to get VM statistics”

I hope this helps.
