Grafana. Configuring a user's dashboard

To monitor the required metrics of cluster nodes and virtual machines, we recommend setting up your own dashboard in Grafana.

Creating a dashboard

1. Enter  → Create → Dashboard.
   
2. Create a unique dashboard name: on the upper right menu, click the icon → enter the name in the Dashboard Name field → Save button.
   

Configuring the panel

1. To add a panel, on the upper right menu, click the  icon.
2. In the panel widget, click the Add Query button.
   
3. In the Query field, specify the data source — graphite_src.
   

4. In the Series field, specify the metric name. Metric names for nodes have the format: 1.node.<node_id>.<node_metric>, metric names for virtual machines — 1.host.<vm_id_name>.<vm_metric>.
   
   

   Comments

   <node_id> — cluster node id.

   <vm_name> — virtual machine id and name. E.g., 16_wizard_gold.

   <node_metric> — cluster node metric. Examples of values:

   • cpu — CPU load;
   • df.root.free — free space in the disk root section;
   • hdd.<device>.reads — disk section read IOPS. For example, hdd.sda1.reads;
   • hdd.<device>.writes — disk section write IOPS. For example, hdd.sdb1.writes;
   • la.mid — average node load;
   • mem — free RAM;
   • net.<interface>.rx — inbound traffic. For example, net.vmbr0.rx;
   • net.<interface>.tx — outbound traffic. For example, net.vmbr0.tx;
   • uptime — node uptime.

   <vm_metric> — virtual machine metric. Examples of values:

   • cpu.* — CPU load;
   • hdd — disk space used;
   • mem.unused — free RAM;
   • net.rx.bytes — inbound traffic;
   • net.tx.bytes — outbound traffic.
5. Enter the  menu and select the data display method in the Visualization field.
   
6. Enter the  menu and specify a discretionary metric name.
   
7. To save settings, 
8. On the upper right menu, click the icon → enter the settings comment → Save button.
