Hello 
Im using the centreon_prometheus_api.pl for multiple scenarios , its great, but I found something annoying. 

/centreon_prometheus_api.pl 
--plugin=cloud::prometheus::restapi::plugin 
--mode=expression 
--hostname=xxxxxxxxx 
--url-path='/api/v1' 
--port='' 
--proto='https' 
--query='namespace,sum by (namespace, pod, cluster) (max by (namespace, pod, cluster) (kube_pod_status_phase{job="kube-state-metrics",namespace=~".*",phase=~"Pending|Unknown"}) * on (namespace, pod, cluster) group_left (owner_kind) topk by (namespace, pod, cluster) (1, max by (namespace, pod, owner_kind, cluster) (kube_pod_owner{owner_kind!="Job"}))) > 0' 
--instance=namespace 
--instance=pod 
--output='Pod %{pod} of %{instance} namespace has been in a non-ready state for longer than 15 minutes.' 
--critical-status='%{namespace} > 0' --verbose --debug


UNKNOWN: No expressions found.

{"status":"success","data":{"resultType":"vector","result":[]}}

Its working great , until there is atleast 1 pod that matches the query. 

 

In my case, all good, but I get the No expressions found. 

Is there a way to accept empty response ? Must be , but I cannot find it via --help. 

Thanks !
