Route Injection

[dgawin]

Hi there,

I hope you are all well.

I successfully installed Wiperf on a raspberry, thanks for this amazing job and the really good howto @wifinigel

But in my wiperf_agent.log I have some strange entries that I don't understand.

Hi Dominik,

Looking at these messages, I suspect there is an issue with the management platform IP address:

2021-01-12 09:05:05,721 - Probe_Log - INFO - Checking we can get to the management platform...
2021-01-12 09:05:05,724 - Probe_Log - INFO - DNS hostname lookup : . Result: 0.0.0.0

The message DNS hostname lookup : . Result: 0.0.0.0 seems to indicate there is no IP address for the management platform.

Check that you have set the exporter_type field to the correct platform type and that the splunk_host or influx_host is correct (depending on which platform you use).

HTH

Nigel.

Hi Nigel,

youre right ... to stupid to modify the file the right way. sorry for that.

Maybe it is possible to print out the exporter_type in the INFO for management platform log entry. ^^

No problem - glad its working.

Good suggestion to improve the information available. I will implement that suggestion in v2.1 if I can. Thanks for the feedback 👍
