I am monitoring the location of some bikes and using Grafana World Map Panel to locate these points on the map. It was working fine till today but then Influxdb stopped automatically. I started it again and found this in logs.
[I] 2017-04-06T07:33:35Z WARN: 85% of max-values-per-tag limit exceeded: (85707/100000), db=vehicleinfo shard=8 measurement=vehicleinfo tag=geohash service=shard
Here geohash is stored as tag, and is necessary to view locations on the worldmap panel. This warning is displayed again and again in the logs. But sometimes influxdb stops working.
What I am getting of this is that there might be a limit on the values of the tags which has been exceeded which is causing the influxdb to stop. Please explain this warning. If there is some limit on the values of these tags, can I change this limit OR can i remove this limit ? as I have to store these geohashes in large numbers.
Also, can I convert these tags into fields ? If yes, then how ?
I know that tags are those values on which we have to perform a query and fields are values which changes frequently and there are very few cases when we have to perform query on them(fields). Please tell me more differences between tags and fields.
