on

ANM
You
can

specify

how

you

ar

e

not

ified

when

thresholds

are

crossed:

•
Alarm
notification,

which
you
view

at
Monitor
>

Alarm

>

Alarms.

•
Email

•
Tr

notification.

Thi

s

method

requires
ANM

5.1

or

l

ater

and

a

supported

mobile
device
with

the

Cisco

ANM

Mobile

app.

For

more

information

about

ANM

Mobile,

see

Chapter

19,
“Using
ANM

Mobile.”
Note
Threshold
crossing

is
detected
using

periodic

polling.

If

a

threshold

is

crossed

between

polling

cycles,
it
is

possible

that

ANM

License

Manager

might

not

issue

an

alert

if

the

condition

recovers

before

the
next
polling

cycle.
Guidelines
and

Restrictions
For
certificates

that

you

have

loaded

on

the

ACE,

you

can

configure

ANM

to

issue

an

alarm

notification
when
the

certificate

expiration

date

is

approaching.

ANM

performs

certificate

expiration

computations
every
24

hours.

The

computation

begins

each

time

ANM

is

st

arted.

Every

subsequent

computation
occurs
24

hou

rs

thereafter.
Note
The
Certificates

window

(Config

>

Devices

>

context

>

SSL

>

Ce

rtificates)

contains

the

Expiry

Date
field,
which

displays

the

certificate

expiration

date.

Due

to

a

known

issue

with

the

ACE

module

and
appliance,
it

is

possible

that

this

field

displays

either

“Null”

or

characters

that

cannot

be

parsed

or

that
are
unreadable.

When

this

issue

occurs,

ANM

cannot

track

the

certificate

expiration

date.

If

the
certificate
is

defined

in

a

threshold

group

configured

for

certificate

expiration

alarm

notifications

and
this
issue

occurs,

ANM

may

not

issue

an

expiration

alarm

when

expected

or

it

may

issue

a

false

alarm.
If
you

encounter

this

issue,

remove

the

certificate

from

the

ACE,

reimport

it,

and

then

verify

that

the
correct
expiration

date

appears

in

the

Certificates

window.
Prerequisites

email

notifications,

you

have

specified

an

SMTP

server

to

use

for

outgoing

emails

(see

the
“Configuring
SMTP

for


Email

Notifications”

section

on

page

17-68 ).
