Status and Update

The Status & Update page lists the active SCI nodes, alerts you to any important notifications, and displays the current firmware version.

Nodes

The following illustration shows an example of the Status and Update screen when the Node tab is selected.

Figure 1. Status and Update Screen with Node Tab selected
The Nodes section lists the active SCI nodes, and includes the following information on each node:
  • Node ID: The ID number of the node
  • Node IP: The IP address of the node
  • Node Token: The Token number or SSH password of the node. This token number is required for a node to connect to another node. The number is available on the UI so that it is a ready reference to the user who wants to connect to a specific node.
  • Node Type: The type of node. There are two types of nodes, namely master and data nodes. One or more data nodes are required as the system scales and grows larger.
  • Node State: The node state is green when in use and red when disconnected and not in use.

Notifications

The following illustration shows an example of the Status and Update screen when the Notifications tab is selected.

Figure 2. Status and Update Screen with Notifications Tab selected

If any notifications are present in this section of the SCI UI, a red notifications icon appears in the upper-right portion of the SCI user interface next to the admin icon. (This icon disappears once the issue has been handled.)

Note: The only current "level" of notification at this time is critical, as shown in the screen above.

In addition, an email notification is sent out every 15 minutes to the email address provided in the My Account screen > Profile section of the SCI UI, which you open by clicking on the admin icon in the upper right of the SCI user interface, as shown in the following figure.

Figure 3. Email Address to Receive Notifications

To receive notifications, you must also be sure that you have configured the outgoing mail server (SMTP) in the Admin dashboard > Settings section.

The following table lists examples of the two types of notifications that you could receive, along with possible solutions.

Table 1. Notifications and Possible Corrective Actions
Notification Description Action(s) to Try
Your master node (IP: 10.x.y.1) has reached 83 percent disk usage. This notification appears whenever one of the SCI nodes has a disk usage of 80% or more. This notification indicates that you could potentially run out of disk space on SCI.
  • Reduce the data retention period by going to the Admin > Settings screen, "Data Retention" section. For more information, refer to the Settings section, "Data Retention" portion.
  • Copy your data to a new SCI with more disk space. If you need assistance, contact Ruckus support.
  • Add new data nodes. Because the Hadoop Distributed File System (HDFS) replication factor is two, you need at least two data nodes in your SCI cluster.
Your Spark cluster (Spark master IP: 10.x.y.2) was unable to accept a job submission. This notification appears when an ETL Spark job is taking a long time, and SCI is unable to submit the next job. This could mean that SCI is unable to ingest data from the controllers and that SCI is unable to continue to collect data. Go to Admin > Diagnostics > Spark Master. Search for "Running Applications." If this section shows more than one job running, check again in a half hour. If there is still more than one job shown running in the "Running Application" section, contact Ruckus customer support to ensure that you are not losing data.

Update

The following illustration shows an example of the Status and Update screen when the Update tab is selected.

The Update section contains the details of the current version of SCI that you are running and the latest version of SCI that is available (if any).
