Dashboards

This feature is only applicable for agent-based monitoring using Prometheus. You will be presented with a notification panel to enable agent-based monitoring if it has not been activated. This feature is introduced in version 1.7.0.

To understand how ClusterControl performs monitoring jobs, see Monitoring Operations.

Enable Agent-Based Monitoring

Opens a side-menu pop-up to configure a Prometheus server. You can re-use an existing Prometheus server for multiple clusters within one ClusterControl instance. For a new Prometheus deployment, ClusterControl will install the Prometheus server on the target host and configure exporters on all monitored hosts according to their role for that particular cluster. If you choose an existing Prometheus server, ClusterControl will connect to the data source and also configure the Prometheus exporters accordingly.

Field Description
Select Host
  • Pick a host to be configured as the Prometheus server. If you already have a running Prometheus server, the dropdown will list out the existing instance and you can pick it up from the list. Ensure ClusterControl can perform passwordless SSH to the target node
Scrape Interval
  • How frequently to scrape targets by default. This is a Prometheus global configuration. See Global Configuration.
Data Retention(days)
Configure Exporters
  • Manually configure individual exporters scrape interval and command-line arguments to be passed.

Monitoring Dashboards

Dashboards are composed of individual monitoring panels arranged on a grid. For MySQL/MariaDB, ClusterControl pre-configures a number of dashboards depending on the cluster type and host’s role. The following table explains them:

Dashboard Cluster Type Description
System Overview MySQL/MariaDB-based Clusters Provides panels of host metrics and usage for an individual host.
Cluster Overview MySQL/MariaDB-based Clusters Provides selected host and database metrics for all hosts for comparison.
MySQL Server – General MySQL/MariaDB-based Clusters Provides panels of general database metrics and usage for the individual database host.
MySQL Server – Caches MySQL/MariaDB-based Clusters Provides important cache-related metrics for the individual database host.
MySQL InnoDB Metrics MySQL/MariaDB-based Clusters Provides important InnoDB-related metrics for the individual database host.
MySQL Replication MySQL/MariaDB Replication Provides panels related to replication for the individual database host.
Galera Overview Galera Cluster Provides cross-server Galera cluster metrics for all database hosts.
Galera Server Charts Galera Cluster Provides panels related to Galera replication metrics for the individual database host.
ProxySQL Overview Clusters with ProxySQL Provides important ProxySQL metrics for individual ProxySQL hosts.
HAProxy Overview Clusters with HAProxy Provides important HAProxy metrics for an individual host.
Field Description
Dashboard
  • A dropdown list of pre-configured dashboards.
Node
  • List of database nodes hostname (or IP address) and its role for the particular cluster. Only for non-global dashboards.
Range Selection
  • Opens a pop-up to configure time range for all panels. It provides common quick ranges, refresh rates and also a date-time picker at the bottom of the window.
Zoom Out
  • Decreases the magnification of the graphs.
Refresh Rate
  • Opens a pop-up to configure time range for all panels. It provides common quick ranges, refresh rates and also a date-time picker at the bottom of the window.
Configuration
  • Opens a pop-up to show exporters grouped by the host and Prometheus global configuration settings.
Re-enable Agent Based Monitoring
  • Reconfigures agent-based monitoring approach. You can use this function to configure this cluster to use a different Prometheus server.
Disable Agent Based Monitoring
  • Disable this monitoring operation mode and back to the agentless approach. You have the option of whether to keep the Prometheus running and continue to pull stats or stop the exporters and Prometheus altogether. Regardless of the chosen option, the Dashboards will also be disabled once the job completes.
