show trending

Displays a list of configured sizes for trending database files, and a list of all objects that are being tracked in the trending database.

show trending <family> 
 
              [ prefix [<address>] | link [<lname>] | router [<rname>]]
 
              [ | { include | exclude | begin } <exp> ] 
 
              [ > <url> ]
 

• family--trend size family; must be one of:
• performance
• event-manager (deprecated)
• link-usage
• address--prefix address in CIDR format (a.b.c.d/n)
• lname--link name, as string (see link command)
• rname--IP address of a router
• exp--a regular expression, to be used as a filter
• url--destination for output

System operations mode, login-level access.

The show trending command will display current configured sizes of the trending database files for the specified trending size family, plus the globally configured sizes.

The output also shows the total disk space used by the trending database, in bytes; whether trending is enabled (by the trending on command); and the number of minutes after the hour when the database snapshot will be made (configured by the snapshots schedule command).

If you use the keyword prefix, the display will show a list of prefixes for which trend data is available. If you also include a specific prefix address in CIDR format, the output will include a list of all files related to that prefix.

If you use the keyword link, the display will show a list of links for which trend data is available. If you also include a specific CNA-configured link name, the display will include a list of all files in the trend database related to that link.

If you use the keyword router, the display will show a list of routers for which trend data is available. If you also include a specific router’s IP address or hostname, the display will include a list of all files in the trend database related to that router.

You can pipe the command through one of the following filters:

• include--shows all lines in the output which contain a match to the specified regular expression
• exclude--shows all lines in the output except those which contain a match to the specified regular expression
• begin--shows all lines in the output beginning with the first match to the specified regular expression

The vertical-line pipe character | is required when a filter is used.

You can send the output to a remote file location, by piping the display to a remote URL (leading > required). See the copy command for URL syntax.
