Configuring Media Flow Controller Fault Notifications (CLI)
Copyright © 2010, Juniper Networks, Inc.
Configuring SNMP consists of setting a system contact and location, admin user parameters,
and Trap Sinks. Traps are only sent if there are Trap Sinks configured and enabled. For more
information on SNMPv2, see
RFC 2578
.
In the Web interface, use the Setup > SNMP page to do this.
In the CLI, use these commands:
snmp ?
(to set all SNMP parameters) and
email notify ?
(to determine who should get notifications) See
“Configuring Media
Flow Controller Fault Notifications (CLI)” on page 240
for details.
Configuring Media Flow Controller Fault Notifications (CLI)
Configure email notifications so key people receive notice of system errors and changes.
The email commands allow you to set email addresses for fault notifications of specified, pre-
defined, events. You can also enable autosupport emails: when certain failures occur Juniper
Networks support automatically receives an email. See
for CLI details including
event name Options” on page 312
and
“email class Options” on page 312
.
To configure fault notifications with the CLI:
Averaged Origin
Bandwidth
(avg_origin_byte_rate
)
Origin Average bandwidth usage, since the system
uptime, is too high
Check if disk cache and RAM cache are
properly utilized by monitoring the
dashboard. Media Flow Controller may
be serving lots of long-tail content or the
content cannot be accommodated in the
RAM/disk cache. Check if the available
disk/RAM cache sizing is adequate for
the traffic load.
Connection Rate
(connection_rate)
Incoming connection rate is too high
Configure traffic redirection thresholds in
the external router/load balancer to
reduce the number of requests redirected
to the Media Flow Controller.
Transaction Rate
(http_transaction_rate
)
HTTP transaction rate is too high
Configure traffic redirection thresholds in
the external router/load balancer to
reduce the number of requests redirected
to the Media Flow Controller.
Port Bandwidth
(perportbyte_rate)
Network port bandwidth usage is high
Configure traffic redirection thresholds in
the external router/load balancer to
reduce the number of requests redirected
to the Media Flow Controller. Configure
additional network ports in Media Flow
Controller to redistribute the requests
evenly across the available ports.
