8 Monitoring cluster operations

Monitoring the status of file serving nodes

The dashboard on the management console GUI displays information about the operational status of

file serving nodes, including CPU, I/O, and network performance information.

To view status from the CLI, use the ibrix_server -l command. This command provides CPU,

I/O, and network performance information and indicates the operational state of the nodes, as shown

in the following sample output:

<installdirectory>/bin/ibrix_server -l

SERVER_NAME STATE CPU(%) NET_IO(MB/s) DISK_IO(MB/s) BACKUP HA

----------- ------------ ------ ------------ ------------- ------ --

node1 Up, HBAsDown 0 0.00 0.00 off

node2 Up, HBAsDown 0 0.00 0.00 off

File serving nodes can be in one of three operational states: Normal, Alert, or Error. These states are

further broken down into categories that are mostly related to the failover status of the node. The

following table describes the states.

DescriptionState

Up: Operational.

Normal

Up-Alert: Server has encountered a condition that has been logged. An event will appear in the

Status tab of the management console GUI, and an email notification may be sent.

Up-InFailover: Server is powered on and visible to the management console, and the management

console is failing over the server’s segments to a standby server.

Up-FailedOver: Server is powered on and visible to the management console, and failover is

complete.

Alert

Down-InFailover: Server is powered down or inaccessible to the management console, and the

management console is failing over the server's segments to a standby server.

Down-FailedOver: Server is powered down or inaccessible to the management console, and

failover is complete.

Down: Server is powered down or inaccessible to the management console, and no standby

server is providing access to the server’s segments.

Error

The STATE field also reports the status of monitored NICs and HBAs. If you have multiple HBAs and

NICs and some of them are down, the state will be reported as HBAsDown or NicsDown.

Monitoring cluster events

X9000 Software events are assigned to one of the following categories, based on the level of severity:
