Use the Viewing Syslog Properties panel in the SAN Volume Controller Console to
view the syslog properties for a cluster.
Introduction
The syslog protocol is a client-server
standard for forwarding log messages from a sender to a receiver on
an IP network. The IP network can be either IPv4 or IPv6. The User
Datagram Protocol (UDP) is used to transmit the syslog message. The
syslog protocol can be used across multiple platforms, which enables
you to integrate log data from different types of storage systems
into a central repository. You can use the SAN Volume Controller Console to
configure and modify your syslog settings. SAN Volume Controller can
transmit syslog messages in fully expanded or concise format.
Attributes
The
following attributes are displayed in the table:
- Server Name
- Displays the name for the syslog server. A valid
name is 1 to 15 ASCII characters. The following characters can be
used: a - z, A - Z, 0 - 9, -, _. The name cannot begin with a number
or the hyphen (-) character. Names starting with syslog are
reserved for SAN Volume Controller default
names.
- IP Address
- Displays the IP address of the syslog server. Both IPv4 and IPv6
address structures are supported.
- SVC Facility
- Displays the SAN Volume Controller facility
for the syslog server. The SAN Volume Controller facility
values displayed on the panel are translated into syslog facility
codes and values.
The SAN Volume Controller facility
of 0 - 3 results in the syslog server receiving messages in concise
format, which provide standard detail on the event. A SAN Volume Controller facility
of 4 - 7 results in the syslog server receiving messages in fully
expanded format, where more details are provided regarding the event.
- Error
- Displays whether the SAN Volume Controller cluster
sends events with the notification type of error to the
syslog server. When an event notification with the
type error is received by the SNMP server, the problem
must be fixed immediately. This notification indicates a serious
problem with the SAN Volume Controller cluster.
For example, the event that is being reported could indicate a loss
of redundancy in the system, and it is possible that another failure
could result in loss of access to data. A hardware failure is the
most typical reason this type of notification is sent, but some configuration
errors or fabric errors also are included in this notification type.
- Warn
- Displays whether the SAN Volume Controller cluster
sends events with the notification type of warning to
the syslog server. A warning notification is sent to
indicate a problem or unexpected condition with the SAN Volume Controller.
Always immediately investigate this type of notification to determine
the effect that it might have on your operation and correct the problem
if necessary. A warning notification does not require any replacement
parts and therefore should not require IBM® Support
Center involvement. However, the event being reported might indicate
a condition that could be fatal to your operating environment; such
as, a critical FlashCopy® operation
has failed.
- Info
- Displays whether the SAN Volume Controller cluster
sends events with the notification type of informational to
the syslog server. For these types of notifications,
no action is necessary to resolve them. This notification indicates
an event that was expected has occurred. For example, a FlashCopy mapping event has completed successfully.
No remedial action is required when these notification types are sent.
