# Consul server monitoring dashboard

This page provides reference information about the [Grafana dashboard configuration included in the `hashicorp/consul` GitHub repository](https://github.com/hashicorp/consul/blob/main/grafana/consul-server-monitoring.json).

## Grafana queries overview

This dashboard provides the following information about service mesh operations.

### Raft commit time

**Description:** This metric measures the time it takes to commit Raft log entries. Stable values are expected for a healthy cluster. High values can indicate issues with resources such as memory, CPU, or disk space.

```promql
consul_raft_commitTime
```

### Raft commits per 5 minutes

**Description:** This metric tracks the rate of Raft log commits emitted by the leader, showing how quickly changes are being applied across the cluster.

```promql
rate(consul_raft_apply[5m])
```

### Last contacted leader

**Description:** Measures the duration since the last contact with the Raft leader. Spikes in this metric can indicate network issues or an unavailable leader, which may affect cluster stability.

```promql
consul_raft_leader_lastContact != 0
```

### Election events

**Description:** Tracks Raft state transitions, which indicate leadership elections. Frequent transitions might suggest cluster instability and require investigation.

```promql
rate(consul_raft_state_candidate[1m])
```

```promql
rate(consul_raft_state_leader[1m])
```

### Autopilot health

**Description:** A boolean metric that shows a value of 1 when Autopilot is healthy and 0 when issues are detected. Ensures that the cluster has sufficient resources and an operational leader.

```promql
consul_autopilot_healthy
```

### DNS queries per 5 minutes

**Description:** This metric tracks the rate of DNS queries per node, bucketed into 5 minute intervals. It helps monitor the query load on Consul’s DNS service.

```promql
rate(consul_dns_domain_query_count[5m])
```

### DNS domain query time

**Description:** Measures the time spent handling DNS domain queries. Spikes in this metric may indicate high contention in the catalog or too many concurrent queries.

```promql
consul_dns_domain_query
```

### DNS reverse query time

**Description:** Tracks the time spent processing reverse DNS queries. Spikes in query time may indicate performance bottlenecks or increased workload.

```promql
consul_dns_ptr_query
```

### KV applies per 5 minutes

**Description:** This metric tracks the rate of key-value store applies over 5 minute intervals, indicating the operational load on Consul’s KV store.

```promql
rate(consul_kvs_apply_count[5m])
```

### KV apply time

**Description:** Measures the time taken to apply updates to the key-value store. Spikes in this metric might suggest resource contention or client overload.

```promql
consul_kvs_apply
```

### Transaction apply time

**Description:** Tracks the time spent applying transaction operations in Consul, providing insights into potential bottlenecks in transaction operations.

```promql
consul_txn_apply
```

### ACL resolves per 5 minutes

**Description:** This metric tracks the rate of ACL token resolutions over 5 minute intervals. It provides insights into the activity related to ACL tokens within the cluster.

```promql
rate(consul_acl_ResolveToken_count[5m])
```

### ACL resolve token time

**Description:** Measures the time taken to resolve ACL tokens into their associated policies.

```promql
consul_acl_ResolveToken
```

### ACL updates per 5 minutes

**Description:** Tracks the rate of ACL updates over 5 minute intervals. This metric helps monitor changes in ACL configurations over time.

```promql
rate(consul_acl_apply_count[5m])
```

### ACL apply time

**Description:** Measures the time spent applying ACL changes. Spikes in apply time might suggest resource constraints or high operational load.

```promql
consul_acl_apply
```

### Catalog operations per 5 minutes

**Description:** Tracks the rate of register and deregister operations in the Consul catalog, providing insights into the churn of services within the cluster.

```promql
rate(consul_catalog_register_count[5m])
```

```promql
rate(consul_catalog_deregister_count[5m])
```

### Catalog operation time

**Description:** Measures the time taken to complete catalog register or deregister operations. Spikes in this metric may indicate performance issues within the catalog.

```promql
consul_catalog_register
```

```promql
consul_catalog_deregister
```
