2.Juniper MX device monitoring template mysql

We can leverage the Juniper MX device monitoring template from Github to configure the Juniper device monitoring.git

https://github.com/Prototype-X/Zabbix-Template-Juniper-MX-BGP4-ipv4-ipv6github

Detailed steps as below.web

Import Template.Juniper.MX.xml file into Zabbix.sql
Copy script LLD.py to /usr/lib/zabbix/externalscriptsexpress
Give the execution permission for LLD.py by running "chmod +x LLD.py"json
If we are using Python2, we need to modify the LLD.py to use python2bash

?

#!/usr/bin/env python
Also make sure we have ipaddress python module is installed, run the command below if not installed.

easy_install ipaddress

run the command below to test if LLD.py is working. If there is json output returned from the command line then there is no problem for the command. (Make sure to change the Juniper IP address accordingly)

            ] 
           
            }

Go to: Template Juniper MX - > Discovery rules -> JunOS BGP4
Set type: external check

Set key:

LLD.py[ "-h" , {HOST.CONN}, "-c" , "{$SNMP_COMMUNITY}" , "-mi" , "{#PEERADDR}" , "-m" , "{#PREFXTBL}" , "{#ADDRTYPE}" , "{#ASNUM}" ]

Associate Template Juniper MX to the host.
Add to your host the {$SNMP_COMMUNITY} macro with your SNMP community as value.
Add to your host the {$BGP_PEER_AS} macro with your list BGP peer remote AS as value (ex: ASN1|ASN2|ASN3). These ASs have a high severity triggers.
Go to filter rules for interfaces: Template Juniper MX -> Discovery rules -> JunOS Interfaces -> Filters
Check filter, edit or delete.

In our case, if the interface we want to monitor is something like em0, we need to add the regular expression "^em[0-9]$" as below

If there is any issue related with LLD, we can enable Zabbix server debug log

set DebugLevel=4 from file /etc/zabbix/zabbix_server.conf
restart Zabbix service by running systemctl restart zabbix-server
