Understanding Cluster Tile

Let us understand a cluster tile by viewing a sample tile as shown below.

A name shown at the topmost on any cluster tile is name of the cluster. The row below it specifies its state. State name is displayed in a band having a specific background color pertaining to its state. On similar lines, the border of the tile is also highlighted in the same color. The various states are Running, Deploying…, Critical, Removing & Deployment Error.

Deploying - When the Cluster / Store is being set up Deployment Error- If there is an error during Cluster Set up Running - When the Cluster is working well with utilization below Warning levels Critical - When there is a Critical error / issue with two possible reasons: a. Any node of Cluster is working with utilization above Alert levels b. Any service is down Warning - When the Cluster is performing above the Warning level but below the Alert levels Adding Nodes - When a node is being added in the cluster Removing Nodes - When a node is being removed from the cluster Removing - When the cluster is getting removed

Number of alerts or warnings are shown in the succeeding block.

Next, CPU and memory utilization is shown pictorially.

The last block displays cluster category and the type of environment it was created in.

The next row displays any alerts or warning on the cluster with its count. Below it, average CPU & Memory utilization (for Running clusters only) is shown. The last row on any cluster tile shows the name of cluster technology like Hadoop.

The color of border for the tile also changes along with its state & border follows the same color as used in band for showing state of cluster.
