Hi,
I am trying to use a dashbaord based on mongodb-exporter.
I used dashboard id 12079 from Grafana labs, and on one of my environments it worked fine, and I can see the definition of the variable “env” is showing in the “preview of values” the correct host:port.
tthe query for the variable is:
label_values(mongodb_connections, instance)
–uploaded is a screenshot for this environment
When I import the same dahsboard to another environment, I can see that the “preview of values” for the same variable is empty.
Hence of course all panels based on this variable are empty.
If I check the metrics for this exporter, thee seem fine. For example:
$ curl -s http://localhost:9216/metrics | grep connections
# HELP mongodb_connections The connections sub document data regarding the current status of incoming connections and availability of the database server. Use these values to assess the current load and capacity requirements of the server
# TYPE mongodb_connections gauge
mongodb_connections{state="active"} 53
mongodb_connections{state="available"} 838694
mongodb_connections{state="current"} 166
also, for other queries entered into an empty panel, even though the job shows “success” the array shows [0] and the pannel is empty.
again, the metric for the same query retruns result fine:
Object
request:Object
url:"api/datasources/proxy/1/api/v1/query_range?query=mongodb_mongod_replset_member_uptime&start=1634719890&end=1634806290&step=30"
method:"GET"
hideFromInspector:false
response:Object
status:"success"
data:Object
resultType:"matrix"
result:Array[0]
How can I debug why the same query/metric does not work inside Grafana?
Grafana version (containerized) is 7.2.2
Prometheus version (containerized) v2.22.0
Thanks,
Tamar
