Understanding Schemas

You can set a management schema for bulk statistics. A schema is a group of attributes
or counters that provide an efficient way to retrieve specific types of information
about the router. The bulk statistics application supports schemas listed in Table 24
on page 215.
NOTE: There are no explicit schema objects for the if-stack and system schemas.
Table 24 on page 215 shows the type of data each schema retrieves.

If-Stats Schema Objects

Table 25 on page 216 describes the if-stats objects that you can configure using the
bulkstats schema subtree if-stats command.
Collector Virtual-Routers

See show bulkstats virtual-routers.
Schema Retrieves
if-stack The interface and interface column configuration. It is a complete retrieval of the
ifStackTable, which stores the configured interfaces and their stacking relationship
on a router.
if-stats Usage data on sets of interface types. The interface usage data is the ifTable/ifXTable
counters. The ifXTable supports 64-bit counters and the data written into the bulk
statistics file supports the 64-bit counters.
igmp Statistics associated with various IGMP components.
policy Statistics associated with a specified policy, a policy type, or traffic tagged by a policy
with a color tag.
qos QoS statistics on egress queues for various interface types. The QoS schema enables
service providers to keep track of network congestion and monitor oversubscription
on the egress queues of the router.
system Global system and per-module statistics and information. The global system statistics
retrieved are the sysUpTime and nvsUtilPct. The per-module statistics and information
retrieved include the intPhysicalDesc, the cpuUtilPct, and the memUtilPct.
