vprobe hypervisor deep observability

stemasmais — Wed, 24 May 2017 12:50:33 GMT

Hi all, I want to create a vprobe script (bettere if written with hemmet) that trace a particular process X. The vprobe documentation is old and poor and I can't find nothing useful.

To be more precise the trace script must print (or write into a file) every function called by the process X. I know how to implement the core process but I don't know which probe intercept.

What can I do?

It's like you said! The vprobe command it's the way to execute the vp scripts but when I create a simple vp script like this below

(vprobe VMM1Hz

(printf "testing\n"))

I obtain this error

vprobe test.vp

vmware-vprobe: Failed to load script in vmkernel: cannot enable probe "VMM1Hz" Not found

and this error

vprobe -c test.vp -m /vmfs/volumes/<volume number>/linux/linux.vmx

vmware-vprobe: Compile error: Syntax error: <cmdline>: line 1, token '.'

but the file is the same!

The config is ok, I think, because I've set the vprobe.allow in /etc/vmware/config and the vprobe.enable in /vmfs/volumes/<volume number>/linux/linux.vmx

Thanks!

To solve this problem I've installed the ESXi 6.5 but the host console still doesn't recognize the vmrun command or the vprobe commands...

Goodmorning

I'm using VMware workstation pro 12 on windows 10 and I'm trying to extract some information from the hypervisor with the vprobe script.

I've added the vprobe.allow = "TRUE" on the following files

C:\ProgramData\VMware\VMware Workstation\config.ini

C:\ProgramData\VMware\VMware Workstation\settings.ini

C:\Users\smais\AppData\Roaming\VMware`config.ini

C:\Users\smais\Documents\Virtual Machines\ubuntu\Ubuntu 64-bit.vmx

The cpnfig.ini is the following file:

installerDefaults.simplifiedUI = "no"

authd.client.port = "902"

authd.proxy.nfc = "vmware-hostd:ha-nfc"

installerDefaults.autoSoftwareUpdateEnabled = "yes"

installerDefaults.autoSoftwareUpdateEnabled.epoch = "14622"

installerDefaults.componentDownloadEnabled = "yes"

installerDefaults.dataCollectionEnabled = "yes"

installerDefaults.dataCollectionEnabled.epoch = "14622"

vprobe.allow = "TRUE"

When I run vmrun with some vprobe command (vprobeListProbes, vprobeLoad, ect) I have the same result every time: Error: Unrecognized command

vmrun is working because I can manage the vm without problems.

What can I do?
