iStats v13 command help

This is a CLI command equivilant to the iRule

ISTAT

commands (see here for more info DevCentral Wiki - iRules ISTAT).

Start with

key

which is made up of class, object, measure type (counter, gauge, string, text, signed, unsigned, bin, dec, hex, timestamp, timeval, uinthex), and measure name to be separated by whitespace and enclosed in double quotes.

e.g.

istats set "uri /12345 counter Requests

would set an iStat named

Requests

under the class

uri

, object named

/12345

and a type of a

counter

The

-s 

is simply a way to write iStats to a file for testing e.g.

istats set -s test.istat "uri /12345 counter Requests" 1

will write the file

test.istat

and create the record

Requests

as above.

You can then use

istats get -s test.istat "uri /12345 counter Requests"

or

istats incr -s test.istat "uri /12345 counter Requests" 1

which will only read and update the local file and not have any effect on the BIG-IP's actual iStats.

A good option is to dump the lot using something like

istats dump -s test.istat

which would look like the following.

test.istat [READONLY]: nextBlockId=704, last update at 2019-04-10 10:45:02

all facts:
   [ uri=/12345 ][Requests] = 8 (2019-04-10 10:56:20)
