Parameters

entry-number: Specifies an event entry by its index in the range of 1 to 65535. If you do not specify an entry, the command displays log entries for all event entries.

Usage guidelines

If the log action is specified for an event, the system adds a record in the event log table each time the event occurs. Each record contains the log entry index, time when the event was logged (the amount of time that elapsed since system startup), and event description.

The system can maintain a maximum of 10 records for an event. The most recent record replaces the oldest record if the number of records reaches 10.

Examples

# Display the RMON log for event entry 99.

<Sysname> display rmon eventlog 99

EventEntry 99 owned by ww is VALID.

LogEntry 99.1 created at 50days 08h:54m:44s uptime.

Parameters

interface-type interface-number: Specifies an interface by its type and number. If you do not specify an interface, the command displays history samples for all interfaces that have an RMON history control entry.

Usage guidelines

RMON uses the etherHistoryTable object to store the history samples of Ethernet statistics for Ethernet interfaces.

To collect history samples for an Ethernet interface, you must first create a history control entry on the interface.

To configure the number of history samples that can be displayed and the history sampling interval, use the rmon history command.

Examples

# Display the RMON history control entry and history samples for Ten-GigabitEthernet 1/0/1.

<Sysname> display rmon history ten-gigabitethernet 1/0/1

sampling-interval: Sets the sampling interval in the range of 5 to 65535 seconds.

absolute: Specifies absolute sampling. RMON compares the value of the variable with the rising and falling thresholds.

delta: Specifies delta sampling. RMON subtracts the value of the variable at the previous sample from the current sampled value, and then compares the difference with the rising and falling thresholds.

startup-alarm: Specifies alarms that can be generated at the first sampling when a rising or falling threshold is reached or exceeded. By default, a rising-falling alarm is generated.

rising: Generates a rising alarm.

falling: Generates a falling alarm.

rising-falling: Generates a rising or falling alarm.

rising-threshold threshold-value1 event-entry1: Sets the rising threshold. The threshold-value1 argument represents the rising threshold in the range of –2147483648 to 2147483647. The event-entry1 argument represents the index of the event that is triggered when the rising threshold is crossed. The value range for the event-entry1 argument is 0 to 65535. If 0 is specified, the alarm does not trigger any event.

falling-threshold threshold-value2 event-entry2: Sets the falling threshold. The threshold-value2 argument represents the falling threshold in the range of –2147483648 to 2147483647. The event-entry2 argument represents the index of the event that is triggered when the falling threshold is crossed. The value range for the event-entry2 argument is 0 to 65535. If 0 is specified, the alarm does not trigger any event.

owner text: Specifies the entry owner, a case-sensitive string of 1 to 127 characters.

Usage guidelines

You can create a maximum of 60 RMON alarm entries.

Each alarm entry must have a unique alarm variable, sampling interval, sample type, rising threshold, or falling threshold. You cannot create an alarm entry if all these parameters for the entry are the same as an existing entry.

To trigger the event associated with an alarm condition, you must create the event with the rmon event command.

RMON samples the monitored alarm variable at the specified sampling interval, compares the sampled value with the predefined thresholds, and performs one of the following operations:

· Triggers the event associated with the rising alarm if the sampled value is equal to or greater than the rising threshold.

· Triggers the event associated with the falling alarm if the sampled value is equal to or less than the falling threshold.

Examples

# Create an alarm entry to perform absolute sampling on the number of octets received on Ten-GigabitEthernet 1/0/1 (object instance 1.3.6.1.2.1.16.1.1.1.4.1) at 10-seconds intervals. If the sampled value reaches or exceeds 5000, log the rising alarm event. If the sampled value is equal to or less than 5, take no actions.

Parameters

entry-number: Specifies an event entry index in the range of 1 to 65535.

description string: Configures an event description, a case-sensitive string of 1 to 127 characters.

log: Logs the event .

log-trap: Logs the event and sends an SNMP notification.

security-string: Specifies the SNMP community name carried in the SNMP notifications. The security-string argument is a case-sensitive string of 1 to 127 characters and is determined by the SNMP configuration. This argument is supported but does not take effect in the current software version.

none: Performs no action.

trap: Sends an SNMP notification.

owner text: Specifies the entry owner, a case-sensitive string of 1 to 127 characters.

NOTE:

The SNMP community name setting for the security-string argument does not take effect even though you can configure it with the command. Instead, the system uses the settings you configure with SNMP when it sends RMON SNMP notifications. For more information about SNMP notifications, see Network Management and Monitoring Configuration Guide.

Usage guidelines

You can create a maximum of 60 event entries.

You can associate an event entry with a standard or private alarm entry to specify the action to take when an alarm condition occurs. Depending on your configuration, the system logs the event, sends an SNMP notification, does both, or does neither.

You can associate an event with multiple alarm entries.

Examples

# Create an RMON log event entry. Specify its index as 10 and the entry owner as user1.

Parameters

entry-number: Specifies a history control entry index in the range of 1 to 65535.

buckets number: Specifies the expected maximum number of samples to be retained for the entry, in the range of 1 to 65535. RMON can retain a maximum of 50 samples for each history control entry. If the expected bucket size exceeds the available history table size, RMON sets the bucket size as closely to the expected bucket size as is possible. However, the granted bucket size will not exceed 50. For example, the bucket size for a history control entry will be 30 if the expected bucket size is set to 55, but the available bucket size is only 30.

interval interval: Specifies the sampling interval in the range of 5 to 3600 seconds.

owner text: Specifies the entry owner, a case-sensitive string of 1 to 127 characters.

Usage guidelines

The system supports a maximum of 100 history control entries.

If an Ethernet interface has a history control entry, RMON periodically samples packet statistics on the interface and stores the samples to the history table. When the bucket size for the history control entry is reached, RMON overwrites the oldest sample with the most recent sample.

You can create multiple RMON history control entries for an Ethernet interface.

Examples

# Create RMON history control entry 1 for Ten-GigabitEthernet 1/0/1.

Parameters

entry-number: Specifies a private alarm entry index in the range of 1 to 65535.

prialarm-formula: Configures a private alarm variable formula, a string of 1 to 255 characters. The variables in the formula must be represented in OID format that starts with a dot (.), for example, (.1.3.6.1.2.1.2.1.10.1)*8. You can configure a formula to perform the basic math operations of addition, subtraction, multiplication, and division on these variables. To get a correct calculation result, make sure the following conditions are met:

· The values of the variables in the formula are positive integers.

· The result of each calculating step is in the value range for long integers.

prialarm-des: Configures an entry description, a case-sensitive string of 1 to 127 characters.

sampling-interval: Sets the sampling interval in the range of 10 to 65535 seconds.

absolute: Specifies absolute sampling. RMON compares the value of the variable with the rising and falling thresholds.

startup-alarm: Specifies alarms that can be generated at the first sampling when a rising or falling threshold is reached or exceeded. By default, a rising-falling alarm is generated.

rising: Generates a rising alarm.

falling: Generates a falling alarm.

rising-falling: Generates a rising or falling alarm.

forever: Configures the entry as a permanent entry. RMON retains a permanent private alarm entry until it is manually deleted.

cycle cycle-period: Sets the lifetime of the entry, in the range of 0 to 4294967 seconds. RMON deletes the entry when its lifetime expires.

owner text: Specifies the entry owner, a case-sensitive string of 1 to 127 characters.

Usage guidelines

You can create a maximum of 50 private alarm entries.

To trigger the event associated with an alarm condition, you must create the event with the rmon event command.

The RMON agent samples variables and takes an alarm action based on a private alarm entry as follows:

1. Periodically samples the variables specified in the private alarm formula.

2. Processes the sampled values with the formula.

3. Compares the calculation result with the predefined thresholds, and then takes one of the following actions:

¡ Triggers the event associated with the rising alarm event if the result is equal to or greater than the rising threshold.

¡ Triggers the event associated with the falling alarm event if the result is equal to or less than the falling threshold.

Examples

# Add a permanent private alarm entry to monitor the ratio of incoming broadcasts to the total number of incoming packets on Ten-GigabitEthernet 1/0/1. Log the rising alarm event when the ratio exceeds 80%, and take no actions when the ratio drops to 5%. The formula is (1.3.6.1.2.1.16.1.1.1.6.1*100/.1.3.6.1.2.1.16.1.1.1.5.1), where 1.3.6.1.2.1.16.1.1.1.6.1 is the OID of the object instance etherStatsBroadcastPkts.1, and 1.3.6.1.2.1.16.1.1.1.5.1 is the OID of the object instance etherStatsPkts.1.

Statistics include number of collisions, CRC alignment errors, number of undersize or oversize packets, number of broadcasts, number of multicasts, number of bytes received, and number of packets received. The statistics are cleared at a reboot.

To display the RMON statistics table, use the display rmon statistics command.

The index of an RMON statistics entry must be globally unique. If the index has been used by another interface, the creation operation fails.

You can create only one RMON statistics entry for an Ethernet interface.

Examples

# Create an RMON statistics entry for Ten-GigabitEthernet 1/0/1. The index is 20 and the owner is user1.

<Sysname> system-view

[Sysname] interface ten-gigabitethernet 1/0/1

[Sysname-Ten-GigabitEthernet1/0/1] rmon statistics 20 owner user1
