Rmon Prialarm - H3C s3600 series Command Manual

system samples the port periodically and stores the samples for later retrieval. The sampled information
includes utilization, the number of errors, and total number of packets.
You can use the display rmon history command to display the statistics of the history control table.
Examples
# Create the history control entry numbered 1 for Ethernet 1/0/1, with the table size being 10, the
sampling interval being 5 seconds, and the owner being user1.

Parameters
entry-number: Extended alarm entry index, in the range 1 to 65535.
prialarm-formula: Expression used to perform operations on the alarm variables, a string of 1 to 256
characters. The alarm variables in the expression must be represented by OIDs, for example,
(.1.3.6.1.2.1.2.1.10.1)*8. The operations available are addition, subtraction, multiplication and division
operations. The operation results are rounded to values that are of long integer type. To prevent invalid
operation results, make sure the operation results of each step are valid long integers.
prialarm-des: Alarm description, a string of 1 to 128 characters.
sampling-timer: Sampling interval (in seconds), in the range 10 to 65535.
delta | absolute | changeratio: Specifies the sample type.
threshold-value1: Upper threshold, in the range 0 to 2147483647.
event-entry1: Index of the event entry that corresponds to the rising threshold, in the range 0 to 65535.
threshold-value2: Lower threshold, in the range 0 to 2147483647.
event-entry2: Index of the event entry that corresponds to the falling threshold, in the range 0 to 65535.
forever: Specifies the corresponding RMON alarm instance is valid permanently.
cycle: Specifies the corresponding RMON alarm instance is valid periodically.
cycle-period: Life time (in seconds) of the RMON alarm instance, in the range 0 to 2147483647.
owner text: Specifies the owner of the alarm entry, a string of 1 to 127 characters.
