The Operating System Layer
This layer tracks the current CPU usage, memory, temperature and the uptime of each hardware component of the
Juniper EX Switch. Besides this, this layer helps you in identifying the number of trap messages that were sent by the
switch for failures of the power supply units , fans and abnormal deduction in temperature of the hardware
components.

1.1.1
CPU Utilization Test
This test monitors the current CPU utilization of each hardware component available in the Juniper EX Switch and
reports whether/not the hardware component is consuming too much of CPU resources.
Purpose
Monitors the current CPU utilization of the Juniper EX Switch
Target of the
test
A Juniper EX Switch
Agent
deploying the
test
An external agent
Configurable
parameters for
the test
1.
TEST PERIOD
- How often should the test be executed
2.
HOST
– The IP address of the Juniper EX Switch
3.
SNMPPORT
– The SNMP Port number of the Juniper EX Switch (161 typically)
4.
SNMPVERSION
– By default, the eG agent supports SNMP version 1. Accordingly, the
default selection in the
SNMPVERSION
list is
v1
. However, if a different SNMP framework is
in use in your environment, say SNMP
v2
or
v3
, then select the corresponding option from
this list.
5.
SNMPCOMMUNITY
– The SNMP community name that the test uses to communicate with
the firewall. This parameter is specific to SNMP
v1
and
v2
only. Therefore, if the
SNMPVERSION
chosen is
v3
, then this parameter will not appear.
