Consul server monitoring dashboard
This page provides reference information about the Grafana dashboard configuration included in the hashicorp/consul GitHub repository.
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.
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.
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.
Election events
Description: Tracks Raft state transitions, which indicate leadership elections. Frequent transitions might suggest cluster instability and require investigation.
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.
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.
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.
DNS reverse query time
Description: Tracks the time spent processing reverse DNS queries. Spikes in query time may indicate performance bottlenecks or increased workload.
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.
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.
Transaction apply time
Description: Tracks the time spent applying transaction operations in Consul, providing insights into potential bottlenecks in transaction operations.
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.
ACL resolve token time
Description: Measures the time taken to resolve ACL tokens into their associated policies.
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.
ACL apply time
Description: Measures the time spent applying ACL changes. Spikes in apply time might suggest resource constraints or high operational load.
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.
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.
