partition not found in the request

Error message

partition not found in the request

What it means

Error returned by buildClickHouseQueryNetwork when the 'partition' key is absent from messagingQueue.Variables; both consumer_group and partition are mandatory for network-latency queries.

Solutions

1. Include partition in the variables map
2. Provide a partition selector/default in the dashboard
3. Validate variables before issuing the request

Example fix

// before
Variables: map[string]string{"consumer_group": "my-group"}

// after
Variables: map[string]string{"consumer_group": "my-group", "partition": "0"}

if (!('partition' in mq.Variables)) throw new Error('partition required');

func hasRequiredVars(v map[string]string, keys ...string) bool { for _, k := range keys { if _, ok := v[k]; !ok { return false } }; return true }

When it happens

Trigger: Requesting Kafka network latency/throughput data without a partition variable in the request.

Common situations: Clients omit the partition template variable, or dashboards default it to empty when no partition is selected.
