Cisco Cisco Expressway 관리 매뉴얼
What metrics are collected from the Expressway?
The following hardware statistics are monitored:
■
aggregation-cpu-sum
■
aggregation-cpu-average
■
df
■
disk
■
load
■
protocols-Tcp
■
protocols-Udp
■
swap
■
Users
■
memory
■
Uptime
■
Process
The following application data are monitored by the custom
exec-app
plugin for collectd:
■
gauge-active_alarms
is the count of active alarms on this Expressway
■
gauge-active_calls
is the count of calls being handled by this Expressway
■
gauge-<service name>
is the status of each system service.
■
gauge-<zone name>_ActiveCalls
counts the active calls in the named zone
■
gauge-<zone name>_BandwidthAllocated
measures the total bandwidth allocated to the named zone
■
gauge-<zone name>_BandwidthLimit
Each of these metrics uses the collectd GAUGE data source type, which allows free-form data. On the collection server,
the full collectd value name will be shown, for example
the full collectd value name will be shown, for example
collectdHostnamecollectd.exec-app.gauge-active_calls
.
Note that zone names are user-configurable and may thus be in conflict with the
. If
your collection server is enforcing the schema, there is a chance that metrics from some zones will not be accepted.
What data is sent to the collection server?
The network plugin uses the
to encapsulate numeric, string, and value data representing the
monitored hardware resources and software processes.
The network plugin pushes the metrics data packets to the analytics server once every interval, using UDP 25826 by
default. The analytics server parses and presents the data in human readable form.
default. The analytics server parses and presents the data in human readable form.
If the analytics server is using the collectd network plugin and csv plugin, then the metrics are stored as small CSV files,
using the metric name and timestamp to create the filename, for example
using the metric name and timestamp to create the filename, for example
gauge-H323-2015-05-21
