•
MetaSANCollector – Collects data about the IFLs (Inter Fabric Links) on the switch.
•
FlowCollector – Collects data about the flow definitions on the switch. Also collects the
subflows for each flow definition. This collector requires the Fabric Insight license on the
switch.
•
VPWwnInfoCollector – Collects data about the VPWWN (Virtual Port World Wide Name) on the
switch.
The Management application collects performance monitoring data via SNMP. Performance
monitoring data is collected asynchronously and is not affected by the collector scheduling.
Performance data (mostly port statistics) is collected every 5 minutes.
Product communication protocols
Table 15 details the protocols that the Management application uses for communication between
products and the Management application server.

ICMP The Internet Control Message Protocol
(ICMP) is part of the Internet Protocol Suite,
as defined in RFC 792.
ICMP messages are typically used for
diagnostic or control purposes or generated
in response to errors in IP operations. Used during initial discovery. Fabric OS
SNMP Simple Network Management Protocol
(SNMP) is an internet-standard protocol for
managing devices on IP networks. SNMP is a
component of the Internet Protocol Suite as
defined by the Internet Engineering Task
Force (IETF). It consists of a set of standards
for network management, including an
application layer protocol, a database
schema, and a set of data objects. Used during discovery, performance polling,
and operation status polling.
Note that performance polling (including
data collection for dashboards) completely
relies on SNMP.
For Historical data collection, the minimum
time interval is 1 minute and 5 minutes for
Fabric OS devices.
For real time graphs, the minimum time
interval is 10 seconds. Fabric OS
HTTP/HTTPS The Hypertext Transfer Protocol (HTTP) is an
application protocol for distributed,
collaborative, hypermedia information
systems. HTTP is the foundation of data
communication for the World Wide Web.
Hypertext Transfer Protocol Secure (HTTPS)
is a communications protocol for secure
communication over a computer network,
with especially wide deployment on the
Internet. Technically, it is not a protocol in
and of itself; rather, it is the result of simply
layering the Hypertext Transfer Protocol
(HTTP) on top of the SSL/TLS protocol, thus
adding the security capabilities of SSL/TLS
to standard HTTP communications.
Used to collect all information required to
manage Fabric OS devices.
You can configure the HTTP/HTTPS protocol
from the Options dialog box (refer to
“Product communication settings” on
page 124).
