Hi,
I’m running grafana (v4.6.3) and influxdb (1.5.0) on two docker containers.
I’ve created a dashboard on Grafana with a template that queries Influx for tag values.
SHOW TAG VALUES WITH KEY=“action.primaryOssName” where “action.primaryVendor” =~ /^$vendor$/
Sometimes, I can’t quite point out when, the template will stop show options and return:
{"results":[{"statement_id":-1,"error":"SHOW TAG VALUES WITH KEY = \"action.primaryOssName\" WHERE \"action.primaryVendor\" =~ /^.*$/ [panic:runtime error: invalid memory address or nil pointer dereference]"}]}
I ran ‘docker logs’ on the influxdb container and found the following error logs:
ts=2018-03-18T05:41:51.130106Z lvl=info msg="Executing query" log_id=06uNqYgl000 service=query query="SHOW TAG VALUES ON cellwize WITH KEY = \"action.primaryOssName\" WHERE (\"action.primaryVendor\" =~ /^.*$/) AND (_tagKey = 'action.primaryOssName')"
ts=2018-03-18T05:41:51.130412Z lvl=error msg="SHOW TAG VALUES WITH KEY = \"action.primaryOssName\" WHERE \"action.primaryVendor\" =~ /^.*$/ [panic:runtime error: invalid memory address or nil pointer dereference] goroutine 3125843 [running]:
