Exporting

Historical

Data

Note

The

data

export

feature

requires

either

the

ANM_ADMIN

role

or

a

role

with

a

ANM_System

privilege

other

than

no-access.

You

can

enable

or

disable

the

data

export

feature

that

allows

ANM

to

export

the

historical

data

that

it

collects

on

the

network

devices

that

it

manages.

You

create

a

data

file

purging

policy

to

enable

or

disable

the

data

export

feature

and

define

the

purging

attributes

associated

with

this

feature.

By

default,

the

data

export

feature

is

enabled,

allowing

ANM

to

export

the

raw

statistical

data

that

it

collects

during

a

polling

session

to

the

comma-separated

values

(CSV)

data

files

in

the

following

directory:

/var/lib/anm/export/historical-data/date-stamp

where

date-stamp

is

the

directory

name,

which

is

based

on

the

date

when

the

file

was

created

and

uses

the

format

YYYY-MM-DD.

For

example,

2010-05-25.

The

exported

data

is

saved

to

the

files

according

to

device

type

(for

example,

ACE_MODULE,

CSS,

or

CSM)

and

its

record

type

(for

example,

RT_INT

or

RT_CPU).
