I am trying to use Grafana to visualize vCenter metrics using InfluxDB. I keep getting this error for one of my panels even though the variables are built and referenced correctly.
Grafana version: 7.5.15
InfluxDB2 version: 2.7.1
Telegraf version: 1.26.3
Query:
from(bucket: v.defaultBucket)
|> range(start: v.timeRangeStart, stop: v.timeRangeStop)
|> filter(fn: (r) => r[“_measurement”] == “vsphere_host_sys”)
|> filter(fn: (r) => r[“_field”] == “uptime_latest”)
|> filter(fn: (r) => r[“vcenter”] =~ ${vcenter})
|> filter(fn: (r) => r[“clustername”] =~ ${clustername})
|> group(columns: [“clustername”])
|> aggregateWindow(every: v.windowPeriod, fn: mean, createEmpty: false)
|> yield(name: “mean”)
Variable Queries:
clustername:
import “influxdata/influxdb/schema”
schema.tagValues(bucket: “vmware”, tag: “clustername”)
vcenter:
import “influxdata/influxdb/schema”
schema.tagValues(bucket: “vmware”, tag: “vcenter”)
