wsrep reporting not working

[mrcheeky123]

wsrep_ready is 'ON' however status=0, when it should be 1 I believe.

[] [root@hostname telegraf.d]# curl -s localhost:9126/metrics|grep -v \#|grep wsrep_ready
mysql_wsrep_ready{host="host.skybet.net",server="127.0.0.1:3306"} 0

What was the reason for closing #6416 and opening this as a duplicate?

@mrcheeky123 Can you share your plugin configuration and Telegraf version?

Looks like I have similiar situation.

@mrcheeky123 or @ADovgalyuk are you still experiencing this issue with the latest version of Telegraf?

Hello @sspaink
Yes, this is still relevant on Maria 10.5 and latest telegraf 1.22:

@mrcheeky123 and @ADovgalyuk can you please test the binary in PR #15063 available as soon as CI finished the tests!? Let me know if this fixes the issue!
