|  | const char * | fmt,
|  | struct rate_ctr_group * | ctrg,
|  | bool | skip_zero
| ) |  |

print a rate counter group to given VTY, formatting the line for each counter according to a format string.

The following format string directives are supported:

- d: The description of the counter
- n: The name of the counter
- c: The current value of the counter
- p: The previous value of the counter
- S: The interval of the counter in seconds
- M: The interval of the counter in minutes
- H: The interval of the counter in hours
- D: The interval of the counter in days
- %%: Print a literal %.

An optional number between % and the letter in a format directive may be used to set a minimum field width. If the expanded format directive is smaller than this width (according to strlen()) the string will be left-padded (if the number is positive) or right-padded (if the number is negative) with spaces. For example, "%25n" prints the counter name left-padded up to a minimum width of 25 columns.

VTY_NEWLINE will be appended to the format string when it is printed.

Parameters

  [in] | vty | The VTY to which it should be printed
  [in] | ctrg | Rate counter group to be printed
  [in] | fmt | A format which may contain the above directives.
  [in] | skip_zero | Skip all zero-valued counters
