Error in plugin [inputs.exec]: metric parse error: expected field at offset 16736:

[accodepull]

I get this error (in title) when I run telegraf however if I run the command on its own its seems that I get all the data displayed on the screen without issues:
./vsanmetrics.py -s vcenter.xxx.xxx -u administrator@vsphere.local -p xxxxx -c xxxx --performance --capacity --health

Running vCenter 6.7.0.11000 and hosts are with 6.7.0, 8169922

Is this something to do with data format retrieved by telegraf and not compliant with influxdb?

Hello @contiandrea,

Could you check if the issue appears with --performance, --capacity or --health parameters? And then, could you provide the output of the command by running directly the script?

Thanks

[accodepull]

Hello, Am pretty sure the issue occurred when there was —performance only. However running the command on its own with —performance seems to work fine as can see lots of data on the output Will only have access to the same system late next week so can give it another try, in meantime let me know if you can suggest anything further. Thanks Get Outlook for iOS<https://aka.ms/o0ukef>

If i may share some experience, I had also a parsing issue running the script within telegraf, and it was also running perfectly fine in shell. (with any performance/capacity or health).

I was using a password with some specific caracters (like "!" ) and after many try to escape these fields (-u and -p ) I add to change to the Adminstrator account and another password without "!".

Don't know for sure if this will help, but give it a try.
Regards,

@knolan1 - thanks will give that a try

@equelin - please see below (when --performance is used)

Hello @knolan1, thanks for the feedback! I was not aware of that...

@accodepull , I'll need to find some time to look at this issue... In the meantime, could you check if you're using the latest release of the script ? Could you try to run the script with the same user who runs the telegraf service?

Regards,

[accodepull]

@equelin - am pretty sure I am not, should I just replace the vsanmetrics.py? (Are there any other dependencies I should replace), thanks

[equelin]

Hello,

Please test with the last release. Yes you just have to replace the file. Also be sure that the user who's running telegraf (he's named telegraf on my ubuntu server) can access to all the prerequisites (pyvmomi, vSAN sdk, etc...).

Feel free to ask if needed.

[accodepull]

Hi, No luck after replacing the file and running —performance (—capacity still works fine), please see below: Process Process-1: Traceback (most recent call last): File "/usr/lib64/python2.7/multiprocessing/process.py", line 258, in _bootstrap self.run() File "/usr/lib64/python2.7/multiprocessing/process.py", line 114, in run self._target(*self._args, **self._kwargs) File "./vsanmetrics.py", line 650, in getPerformance except vmodl.fault.NotFound as e: File "/usr/lib/python2.7/site-packages/pyVmomi/VmomiSupport.py", line 262, in __getattr__ raise AttributeError(attr) AttributeError: NotFound Get Outlook for iOS<https://aka.ms/o0ukef>

Ok then, I think we should start again from the beginning ;-) Could you provide more insights about your environment ?

• OS
• Python version
• Pyvmomi version
• vSAN SDK for Python version
• vCenter / VSAN version

Regards

[accodepull]

sure, the ultimate machine and target environment I want to run this on are: (and on which I got the last couple of errors I sent you)

OS --> CentOS 7
Python version --> 2.7.5
Pyvmomi version --> 6.7.0
vSAN SDK for Python version -- not sure how to obtain the version
vCenter / VSAN version --> VCSA 6.5U2/vSAN 6.2

@equelin - did you manage to replicate the issue/understand why it is failing?

[myusufe]

I have the same issue, did anyone get resolve on this issue?

[accodepull]
