Hi there!
I am having the same problem as listed in this issue 3006
I have a Grafana (Version 4.6.1 (commit: cac8b97)) instance and an InfluxDB instance both running on the same host. When I try to add the InfluxDB as a data source I get this error
… and in the top right corner I see a green box that says “Datasource updated”
The result is that Grafana is unable to fetch data from InfluxDB
With nmap I can verify that InfluxDB is indeed bound to 8086 and I can query it using the InfluxDB HTTP API. This is what I see in the Firefox dev tools when I try to add the data source.
Network tab
It appears that the GET request is never answered by InfluxDB, but running a tcpdump instance on the loopback interface show that this is not the case, the request is in fact never sent to InfluxDB. Running the same query using cURL gives
$ curl "http://localhost:8086/query?db=nyanstats_liveview&q=SHOW%20DATABASES&epoch=ms"
{"results":[{"statement_id":0,"series":[{"name":"databases","columns":["name"],"values":[["_internal"],["nyanstats_liveview"],["nyanstats_sysdiag"],["nyanstats_shapingobjects"]]}]}]}
Proving that InfluxDB is indeed working as expected. I would appreciate any help I could get in resolving this issue.
