Failed to evaluate queries and expressions: failed to execute conditions: plugin unavailable
bestboylm opened this issue · 9 comments
Hello
I get a error when I use this data source plugin
it is normal in explorer, but when I want to create an alert rule, I get this API ERROR
There are related error prompts in the logs in grafana , and my plugin service doesn't receive any new requests
t=2022-03-08T18:16:30+0800 lvl=eror msg="API error" logger=context userId=1 orgId=1 uname=admin error="Failed to evaluate queries and expressions: failed to execute conditions: plugin unavailable" remote_addr= t=2022-03-08T18:16:30+0800 lvl=info msg="Request Completed" logger=context userId=1 orgId=1 uname=admin method=POST path=/api/v1/eval status=400 remote_addr= time_ms=2 size=23 referer="https://mygrafana/grafana/alerting/new?returnTo=%2Falerting%2Flist"
I did not find a corresponding solution!
Grafana Version: 8.3.4
JSON: 0.4.1
Thanks in advance
Try to use Client instead of Server in datasource settings in order to be able to better debug your api.

This API error still exists when I change the data source settings, and use Browser.
This seems to be Grafana's error, but I'm not sure.
Something is wrong with you api. Switching to Browser can only help you debug it in your browser since you can see the pure request grafana client makes to your backend.
my data source service doesn't get request info when I click "Run queries" in the create alert rule interface.
request just send to the Grafana, and get this status 400 API error.
The data example returned by my data source service:
/search
[
"mem_info",
"cpu_info"
]
/query
[{
'columns': [{
'text': 'time',
'type': 'time'
}, {
'text': 'mem_info',
'type': 'number'
}],
'rows': [
