trending size (deprecated)

NOTE: Starting with CNA version 4, this command will no longer need to be used as the trending sizes will be automatically determined by CNA.

Sets the size of files to be maintained by CNA’s trending database.

trending size <family> 
 
              { sample | hourly | daily | weekly | monthly | yearly }
 
              <number>
 
no trending size [ <family> ]
 
                 [ sample | hourly | daily | weekly | monthly | yearly ]
 

• family--specifies which group of trend sizes; can be one of:
• performance
• event-manager
• link-usage
• number--number of datapoints to keep; allowable ranges are:
• sample--720 through 259200 (18720 through 600000 for link-usage family)
• hourly--72 through 4320
• daily--7 through 730
• weekly--4 through 208
• monthly--12 through 60
• yearly--5 through 10

Must be in report configuration mode (config-report), which requires privileged-level access. Requires the optional CNA Analysis and Reporting Module.

Available for use multiple times in the configuration.

• 15000 sample (100000 for link-usage family)
• 120 hourly
• 30 daily
• 13 weekly
• 24 monthly
• 5 yearly

When trending is on (see the trending on command), CNA maintains a round robin database of measurements over a period of time, for each of three groupings of data: events, performance, and link usage. Performance data is obtained from both the hourly snapshot of the live database and from the live database itself.

Use the trending size command to set the maximum number of records in each of the database tables. When a table fills to its maximum, incoming data overwrites the oldest records.

Use the no form of the command without an interval keyword to reset all trending sample sizes to their defaults.

Use the no form of the command with an interval keyword (sample, hourly, daily, weekly, monthly or yearly) to reset the specified sample size to its default.

If you specify a family name with the no form, only those sizes will be reset. If you do not specify a family name, all sizes will be reset.

See the clear trending command.
