Redfish error parsing input: invalid character '<'

Hi guys.
Ive configured telegraf redfish to scrape data from HPE iLO.
probably misunderstanding how to use
computer_system_id. i set computer_system_id = “1”
but getting error [inputs.redfish] Error in plugin: error parsing input: invalid character ‘<’ looking for beginning of value that look like something json.Unmarshaler would throw out.
i can access /redfish/v1/systems/1 in api via curl and get valid json in return.
what am i missing ?
Thank you.

Can you provide your telegraf configuration so we can see what it’s trying to do?

Thank you.
This is my config file.
address = “https://serveraddress
username = “admin”
password = “pass”
insecure_skip_verify = true

And i can get results with:
curl https://serveraddress/redfish/v1/systems/1 -i --insecure -u admin:“pass” -L

It looks like the inputs.redfish plugin is getting HTML rather than JSON returned to it.

Looking at the plugin code, it looks like it will call https://serveraddress/redfish/v1/Systems/1 (note that the S in Systems is capitalized). If you call curl with that URL (including capitalization) do you still get JSON?

seems that way.

Hey @naorw, I don’t think this is your fault. Can you open a bug with the context you provided here? Then I can ping the author to take a look at it.


Hi, i already did and i think you already did :)) i’ve opened the topic here just a big before github.

Thank you :slight_smile:

Guys i see that there is a fix ready, do you have any estimate when it will get into version?
thank you.

Hey @naorw,
I don’t know. I would suggest asking on the issue. You could always install the nightly.

Thank you, i might go for it :slight_smile:
