Items collected

Group Name Description Type Key and additional info
CPU {#SNMPVALUE}: CPU utilization

MIB: JUNIPER-MIB

The CPU utilization in percentage of this subject. Zero if unavailable or inapplicable.

Reference: http://kb.juniper.net/library/CUSTOMERSERVICE/GLOBAL_JTAC/BK26199/SRX%20SNMP%20Monitoring%20Guide_v1.1.pdf

SNMP system.cpu.util[jnxOperatingCPU.{#SNMPINDEX}]

MIB: JUNIPER-MIB

SNMP sensor.fan.status[jnxOperatingState.4.{#SNMPINDEX}]
Inventory Hardware serial number

MIB: JUNIPER-MIB

The serial number of this subject, blank if unknown or unavailable.

SNMP system.hw.serialnumber

Preprocessing:

- DISCARD_UNCHANGED_HEARTBEAT: 1d

Inventory Hardware model name

MIB: JUNIPER-MIB

The name, model, or detailed description of the box,indicating which product the box is about, for example 'M40'.

SNMP system.hw.model

Preprocessing:

- DISCARD_UNCHANGED_HEARTBEAT: 1d

Inventory Operating system

MIB: SNMPv2-MIB

SNMP system.sw.os[sysDescr.0]

Preprocessing:

- REGEX: kernel (JUNOS [0-9a-zA-Z\.\-]+) \1

- DISCARD_UNCHANGED_HEARTBEAT: 1d

Memory {#SNMPVALUE}: Memory utilization

MIB: JUNIPER-MIB

The buffer pool utilization in percentage of this subject. Zero if unavailable or inapplicable.

Reference: http://kb.juniper.net/library/CUSTOMERSERVICE/GLOBAL_JTAC/BK26199/SRX%20SNMP%20Monitoring%20Guide_v1.1.pdf

SNMP vm.memory.util[jnxOperatingBuffer.{#SNMPINDEX}]
Power_supply {#SNMPVALUE}: Power supply status

MIB: JUNIPER-MIB

If they are using DC power supplies there is a known issue on PR 1064039 where the fans do not detect the temperature correctly and fail to cool the power supply causing the shutdown to occur.

This is fixed in Junos 13.3R7 https://forums.juniper.net/t5/Routing/PEM-0-not-OK-MX104/m-p/289644#M14122

SNMP sensor.psu.status[jnxOperatingState.2.{#SNMPINDEX}]
Status Overall system health status

MIB: JUNIPER-ALARM-MIB

The red alarm indication on the craft interface panel.

The red alarm is on when there is some system

failure or power supply failure or the system

is experiencing a hardware malfunction or some

threshold is being exceeded.

This red alarm state could be turned off by the

ACO/LT (Alarm Cut Off / Lamp Test) button on the

front panel module.

SNMP system.status[jnxRedAlarmState.0]
Temperature {#SENSOR_INFO}: Temperature

MIB: JUNIPER-MIB

The temperature in Celsius (degrees C) of {#SENSOR_INFO}

SNMP sensor.temp.value[jnxOperatingTemp.{#SNMPINDEX}]

Triggers

Name Description Expression Severity Dependencies and additional info
{#SNMPVALUE}: High CPU utilization (over {$CPU.UTIL.CRIT}% for 5m)

CPU utilization is too high. The system might be slow to respond.

{TEMPLATE_NAME:system.cpu.util[jnxOperatingCPU.{#SNMPINDEX}].min(5m)}>{$CPU.UTIL.CRIT} WARNING
{#SNMPVALUE}: Fan is in critical state

Please check the fan unit

Device has been replaced (new serial number received)

Device serial number has changed. Ack to close

{TEMPLATE_NAME:system.hw.serialnumber.diff()}=1 and {TEMPLATE_NAME:system.hw.serialnumber.strlen()}>0 INFO

Manual close: YES

Operating system description has changed

Operating system description has changed. Possible reasons that system has been updated or replaced. Ack to close.

{TEMPLATE_NAME:system.sw.os[sysDescr.0].diff()}=1 and {TEMPLATE_NAME:system.sw.os[sysDescr.0].strlen()}>0 INFO

Manual close: YES

{#SNMPVALUE}: High memory utilization ( >{$MEMORY.UTIL.MAX}% for 5m)

The system is running out of free memory.

{TEMPLATE_NAME:vm.memory.util[jnxOperatingBuffer.{#SNMPINDEX}].min(5m)}>{$MEMORY.UTIL.MAX} AVERAGE

System status is in critical state

Please check the device for errors

{TEMPLATE_NAME:system.status[jnxRedAlarmState.0].count(#1,{$HEALTH_CRIT_STATUS},eq)}=1 HIGH
{#SENSOR_INFO}: Temperature is above warning threshold: >{$TEMP_WARN:""}

This trigger uses temperature sensor values as well as temperature sensor status if available

{TEMPLATE_NAME:sensor.temp.value[jnxOperatingTemp.{#SNMPINDEX}].avg(5m)}>{$TEMP_WARN:""}

Recovery expression:

{TEMPLATE_NAME:sensor.temp.value[jnxOperatingTemp.{#SNMPINDEX}].max(5m)}<{$TEMP_WARN:""}-3
WARNING

Depends on:

- {#SENSOR_INFO}: Temperature is above critical threshold: >{$TEMP_CRIT:""}

{#SENSOR_INFO}: Temperature is above critical threshold: >{$TEMP_CRIT:""}

This trigger uses temperature sensor values as well as temperature sensor status if available

{TEMPLATE_NAME:sensor.temp.value[jnxOperatingTemp.{#SNMPINDEX}].avg(5m)}>{$TEMP_CRIT:""}

Recovery expression:

{TEMPLATE_NAME:sensor.temp.value[jnxOperatingTemp.{#SNMPINDEX}].max(5m)}<{$TEMP_CRIT:""}-3
HIGH
{#SENSOR_INFO}: Temperature is too low: <{$TEMP_CRIT_LOW:""}

-

{TEMPLATE_NAME:sensor.temp.value[jnxOperatingTemp.{#SNMPINDEX}].avg(5m)}<{$TEMP_CRIT_LOW:""}
