Collecting Bulk Statistics

The router offers an efficient data collection and transfer facility for accounting applications. The E-series router SNMP MIBs extend the accounting data collection mechanism defined in the Accounting-Control-MIB (RFC 2513) to include support for connectionless networks.

Service providers need reasonably accurate data about customers’ use of networks. This data is used for billing customers and must be available at a customer’s request. Accounting applications based on SNMP polling models consume significant network bandwidth because they poll large volumes of data frequently.

Unfortunately, SNMP is not well suited for gathering large volumes of data, especially over short time intervals. It is inadequate for use by accounting applications because:

The SNMP PDU layout has a low payload-to-overhead ratio.
Processing SNMP PDUs is expensive because objects and tables need to be sorted in lexicographic order.

The router avoids the need for continuous polling of SNMP statistics by using applications known as collectors to retrieve data. You can configure up to six collectors. The router sends collected statistics through FTP to assigned hosts, known as receivers. You must assign a primary receiver to each collector, and you can assign a secondary receiver for redundancy.

Note: The basic-encoding-rules (BER)–encoding choice is not supported.

You can collect interface bulk statistics based on sets of virtual router groups. If sets of virtual router groups generally correspond to ISPs, you can then forward the relevant data to a particular ISP.

To configure a collector to include data from a specific list of virtual routers, you must first configure a collector and then associate a router set with it. A collector can have up to 64 virtual routers associated with it.

To collect bulk statistics for a subset of all configured subinterfaces, you can define the subinterfaces using the following syntax:



 
Slot/Port[.subInterfaceId]

Per virtual router collection is supported on the if-stats and igmp schemas. It is supported on all interface types supported by BulkStats. Collectors modified to use per virtual router collection or configured after a collector has started have a time delay (up to the configured time in seconds) until an active collector starts again.

The maximum number of interfaces for each type of interface and line module can differ. Bulk statistics can collect these statistics when you configure the slots with their respective interfaces to the corresponding maximum values. For information about maximum values see JUNOSe Release Notes, Appendix A, System Maximums.

Note: Define all interface types before you map a collector to the if-stats schema to ensure that you display statistics for all configured interfaces in the first interval.

The name of the bulk statistics file that is transferred to the host when there is a collectorSequence attribute in the remote name is as follows:



 
fileName - z - mmddHHMM - s. sts

where:

fileName—Name of the file, which includes sysName, sysUpTime, depending on the attributes specified
-z—Receiver index value
mmddHHMM—Timestamp when the receiver is created in month/day/hour/minute format
-s—Actual sequence number

Understanding Counter Discontinuity

Interface counter discontinuity can occur when a counter wraps or after a line module is reloaded or reset. If one of these actions occurs, applications that utilize the counters in expressions or calculations generate erroneous values and misleading graphs.

Because counters are 64 bits long, the possibility of a counter’s wrapping naturally would occur so infrequently (for example, in many hundreds of years) that this scenario is not recognized as an issue.

Counter discontinuity does occur, however, when you reload or reset a line module. To indicate reloading or resetting, bulk statistics files contain a record similar to the following:



{Controller down slot 3, TUE OCT 29 2004 14:25:10.370 UTC}

This record provides a mechanism by which applications can detect discontinuity events. To take advantage of this detection capability, the bulk statistics parsing entity should use the record to terminate expression or formula calculations for the indicated slot and to establish a new baseline.

Configuring Collectors and Receivers

To configure the router to collect statistics:

Add names to the FTP host table for the primary and secondary (optional) receivers.
See Copying and Redirecting Files in Managing the System , for information about adding names to the host table.
Specify the type of interface on which you want to collect statistics.host1(config)#bulkstats interface-type ppp collector 2
Specify the parameters for the receivers.host1(config)#bulkstats receiver 1 remote-name js:/ftptest/bulk%s%s.sts sysName sysUpTime

(Optional) Assign the secondary receiver.host1(config)#bulkstats collector 2 secondary-receiver 5
(Optional) Specify the time for which the system transfers data.host1(config)#bulkstats collector 2 interval 1000
(Optional) Set the maximum size of the bulk statistics file.host1(config)#bulkstats collector 2 max-size 20480
(Optional) Add descriptive information to the bulk statistics file.host1(config)#bulkstats collector 2 description customer xyz
(Optional) Set the encoding scheme of the ifDescr and ifName objects.host1(config)#bulkstats interfaces description-format common
(Optional) Set the system to retrieve bulk statistics once only.host1(config)#bulkstats collector 2 single-interval
(Optional) Configure bulk statistics traps.host1(config)#bulkstats traps nearly-full
(Optional) Collect bulk statistics per virtual router. host1(config)#bulkstats virtual-router-group collector 2 routerISP3

Note: The bulk statistics feature supports generating files on a per interface basis.

bulkstats collector

Examplehost1(config)#bulkstats collector 2
Use the no version to delete the collector.
See bulkstats collector.

bulkstats collector

Use to specify the way the collector retrieves bulk statistics.
Examplehost1(config)#bulkstats collector 2 collect-mode auto
Use the no version to specify that either the user or the system will initiate transfers manually.
See bulkstats collector.

bulkstats collector

Use to add descriptive information to the bulk statistics file.
Examplehost1(config)#bulkstats collector 2 description customer xyz
Use the no version to remove descriptive text from the bulk statistics file.
See bulkstats collector.

bulkstats collector

Use to specify the time interval in seconds for which the collector transfers data to the receivers.
Examplehost1(config)#bulkstats collector 2 interval 1000
Use the no version to set this time to the default, 360 seconds (6 minutes).
See bulkstats collector.

bulkstats collector

Use to set the maximum size of the bulk statistics file for all collectors combined. Even when you configure more than one collector, the first maximum file size configured is the combined size of all collectors.
The maximum file size that you can configure is 20971520 bytes. However, if you do not configure a maximum size, then the maximum file size defaults to 5767168 bytes.
Although the CLI accepts the commands, you cannot unconfigure or modify the configuration of the maximum file size until the router is rebooted.
Examplehost1(config)#bulkstats collector 2 max-size 20480
Use the no version to set the size of the bulk statistics file to the default, 5767168 bytes.
See bulkstats collector.

bulkstats collector

Use to assign the primary receiver to which the system transfers data.
The index for the receiver must match the index that you specified with the bulkstats receiver remote-name command.
Examplehost1(config)#bulkstats collector 2 primary-receiver 7
Use the no version to clear the primary receiver and disable the collector.
See bulkstats collector.

bulkstats collector

Use to assign the secondary (that is, the backup) receiver to which the system transfers data.
The index for the receiver must match the index you specified with the bulkstats receiver remote-name command.
Examplehost1(config)#bulkstats collector 2 secondary-receiver 5
Use the no version to clear the secondary receiver.
See bulkstats collector.

bulkstats collector

Use to set the system to retrieve bulk statistics once only, rather than periodically.
Examplehost1(config)#bulkstats collector 2 single-interval
Use the no version to set the system to retrieve bulk statistics periodically, the default situation.
See bulkstats collector.

bulkstats interfaces description-format common

Use to set the encoding scheme of the ifDescr object that the bulk statistics application reports to the conventional industry method.
This command provides compatibility with software that uses the industry encoding scheme.
For more information, see Configuring Encoding Method .
Examplehost1(config)#bulkstats interfaces description-format common
Use the no version to return to the proprietary method of encoding.
See bulkstats interfaces description-format common.

bulkstats interface-type

Use to configure the interface or subinterface type on which you want to collect statistics.
You can provide an interface specifier (location) to identify a specific interface on which you want to collect statistics.
If you define more than one collector, you must specify a unique collector index, in the range 1–65535.
The supported interface types are:
- atm—Collects statistics on ATM interfaces
- atm1483—Collects statistics on ATM 1483 interfaces
- ethernet—Collects statistics on Ethernet interfaces
- frame-relay—Collects statistics on Frame Relay interfaces
- frame-relay-sub—Collects statistics on Frame Relay subinterfaces
- hdlc—Collects statistics on Cisco HDLC interfaces
- ip—Collects statistics on IP interfaces
- mplsMajor—Collects statistics on MPLS major interfaces
- mplsMinor—Collects statistics on MPLS minor interfaces
- mplsL2shim—Collects statistics on MPLS shim interfaces
- ppp—Collects statistics on PPP
- vlan—Collects statistics on VLAN subinterfaces
  
  Note: You cannot collect statistics on the SRP Ethernet interface.
Example 1host1(config)#bulkstats interface-type ppp 3/1 collector 2
Example 2host1(config)#bulkstats interface-type vlan 2/3:1 collector 1
Example 3 host1(config)#bulkstats interface-type mplsMajor 2/3:1 collector 1
Use the no version to delete the interface type from bulk statistics collection. Deletion of a particular interface type takes effect at the next collection interval.
See bulkstats interface-type.

bulkstats receiver remote-name

Use to configure the parameters for receivers.
Bulk statistics transfers require the configuration of a remote FTP server.
The receivers must appear in the FTP host table. The name of the host must match the name you specify with this command. The hostname is relative to the virtual router’s context when you issue this command.
When specifying the remote filename for bulk statistics, you must precede the filename with the hostname followed by the :/ characters.
Examplehost1(config)#bulkstats receiver 1 remote-name js:/ftptest/bulk%s%s.sts sysName sysUpTime

Note: The % variables in the remote name are replaced at runtime with the sysName and sysUpTime parameters to produce variable filenames on the remote host.
Use the no version to delete the receiver.
See bulkstats receiver remote-name.

bulkstats traps

Use to configure bulk statistics traps.
You must configure SNMP correctly and specify a valid trap source. Otherwise, the system will not send SNMP traps.
Examplehost1(config)#bulkstats traps nearly-full
Use the no version to disable the trap.
See bulkstats traps.

bulkstats virtual-router-group

Use to collect interface statistics for each virtual router.
A collector can have a maximum of 64 virtual routers associated with it.
Routers are identified by their assigned name or router index.
Supported only on if-stats and igmp schemas.
Supported on all interface types supported by the bulk statistics application.
Collectors modified to use per virtual router collection or configured after a collector has started have a time delay until an active collector starts again.
Examplehost1(config)#bulkstats virtual-router-group collector 2 routerISP3
Use the no version to prevent bulkstats from being reported for virtual router groups.
See bulkstats virtual-router-group.

Deleting All Bulkstats Configurations

Although individual bulkstats commands allow you to disable or delete a specific bulkstats parameter, the CLI also allows you to remove all bulkstats configurations from the router at one time.

no bulkstats

Use to remove all bulkstats configurations from the router at one time.
Examplehost1(config)#no bulkstats
See no bulkstats.

Monitoring Collection Statistics

To view the parameters the router uses to collect statistics, use the following show bulkstats commands.

To include or exclude lines of output based on a text string that you specify, use the output filtering feature for show commands. For details, see Command-Line Interface.

See show bulkstats virtual-routers.

Configuring Schemas

You can also 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 five schema configurations: igmp, if-stack, if-stats, policy, and system.

Note: There are no explicit schema objects for the if-stack and system schemas.

Table 25 shows the type of data each schema retrieves.

Table 25: Data Retrieved According to Schema

Schema	Retrieves
igmp	Statistics associated with various IGMP components.
if-stack	The interface and interface column configuration. It is a complete retrieval of the ifStackTable, and using it can dramatically reduce the time to discover 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. Note that the ifXTable supports 64-bit counters and the data written into the bulk statistics file supports the 64-bit counters.
policy	Statistics associated with a specified policy, a policy type, or traffic tagged by a policy with a color tag.
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.

igmp Objects

Table 26 presents igmp objects you can configure using the bulkstats schema subtree command.

All the schema if-stats objects in Table 27 apply to both layer 2 and layer 3 interfaces, except usdAcctngSpoofedPkts, which is specific to layer 3.

Defining all interface types before you map a collector to the if-stats schema ensures that you display statistics for all configured interfaces in the first interval.

You can get more accurate rate statistics by using the time-offset parameter. To use this parameter you must navigate to the if-stats subtreelist. The time-offset parameter is included in each bulk statistics interface record and is the offset from the master interval at which the record was collected.

bulkstats schema

Use to create the schema for collecting bulk statistics.
Examplehost1(config)#bulkstats schema 4

Use the no version to delete the specified schema.

Note: If you create a collector but there is no schema for that collector, the collector will not be active, and a schema will be created automatically for that collector to collect if-stats for all subtree attributes.

See bulkstats schema.

bulkstats schema subtree

Use to set the schema for collecting data. Specify one of the following keywords:
- if-stack—Retrieves the interface and interface column configuration.
- if-stats—Retrieves interface usage data on sets of interface types; using the subtreelist keyword along with the if-stats keyword lets you specify specific counters and lets you set the time-offset parameter; using the if-create-delete-time-stats keyword along with the if-stats keyword retrieves interface final statistics (interface statistics that may be lost during higher create or delete frequency) on a per-interface basis.
- igmp—Retrieves IGMP usage data; using the subtreelist keyword along with the igmplist keyword lets you obtain statistics for one or more specific IGMP lists.
- policy—Retrieves policy usage data.
- system—Retrieves global system and per-module statistics and information.

Configuring Interface Numbering Mode

E-series routers support the RFC 1213 interface numbering mode on bulkstats. This mode is contrasted with the default interface numbering mode.

The RFC 1213 numbering mode is based on a 32-bit contiguous integer value starting from 1 and ranging to ifNumber. This mode differs from the default interface numbering mode, which encodes a type field in the upper 8 bits of a 32-bit integer. The use of the upper 8 bits creates large gaps in the ifIndex numbering scheme.

There is no re-use of ifIndex values in RFC 1213 mode, whereas in the default interface numbering mode, ifIndex values can be re-used. In the default interface numbering mode, re-use of ifIndex values across reboots is permitted and is basically known as ifIndex re-numbering.

In RFC 1213 mode, however, the interface numbers are not re-used during a single initialization of the device and renumbering of ifIndexes occurs after a system reboot. In the default interface numbering mode, ifIndexes are persistent across system reboots and can be reused without resetting the value of sysUpTime.

In RFC 1213 mode, two parameters control the size of the ifIndex range and the total number of interfaces in the standard interface tables—maxIfIndex and maxIfNumber. There is no such control in the default interface numbering mode.

In RFC 1213 mode, interface creations should not result in gaps in the ifIndex range. A gap that results from the deletion of an interface is acceptable because it is handled by older network management applications. The gaps are eliminated after the router is rebooted. However, in the default interface numbering mode, large gaps occur from the creation of interfaces due to the use of the upper 8 bits of the ifIndex for interface type encoding. Gaps are not eliminated after a system reboot.

In RFC 1213 mode, small gaps can occur in the creation of IP interfaces when virtual routers are used. These gaps are minimized but not eliminated when the router is rebooted.

Rather than seeing an ifIndex value of 1 and 10066329, for example, a management client would see ifIndex values of 1 and 2.
