Run this command to list Docker images
$ docker image
Run this command to list running containers
$ docker ps
Run this command to list all containers
$ docker ps -a
Run this command to list containers
$ docker-compose ps
Run this command to list networks
$ docker network ls
$ sudo apt install snmp
Verify
$ snmpwalk --version
$ snmpwalk --help
Run this snmpwalk command to use the community public, snmp version 2c, ip 100.123.1.0, oid .1.3.6.1.2.1.2.2
$ snmpwalk -v 2c -c public 100.123.1.0 .1.3.6.1.2.1.2.2
Run these commands to test oids on Junos devices:
jcluser@vMX-addr-4> show snmp mib walk .1.3.6.1.2.1.15.3.1.7
bgpPeerRemoteAddr.192.168.1.2 = 192.168.1.2
bgpPeerRemoteAddr.192.168.2.2 = 192.168.2.2
bgpPeerRemoteAddr.192.168.3.2 = 192.168.3.2
jcluser@vMX-addr-4> show snmp mib walk .1.3.6.1.2.1.15.3.1.2
bgpPeerState.192.168.1.2 = 6
bgpPeerState.192.168.2.2 = 6
bgpPeerState.192.168.3.2 = 6
jcluser@vMX-addr-4> show snmp mib get bgpPeerState.192.168.1.2
bgpPeerState.192.168.1.2 = 6
for troubleshooting purposes you can run this command
$ docker logs telegraf-openconfig
start a shell session in the telegraf container
$ docker exec -it telegraf-openconfig bash
Run this command to print the telegraf version
# telegraf --version
verify the telegraf configuration file
# more /etc/telegraf/telegraf.conf
exit the telegraf container
# exit
for troubleshooting purposes you can run this command
$ docker logs telegraf-snmp
start a shell session in the telegraf container
$ docker exec -it telegraf-snmp bash
Run this command to print the telegraf version
# telegraf --version
verify the telegraf configuration file
# more /etc/telegraf/telegraf.conf
The MIB are in the directory /usr/share/snmp/mibs. Run this command to verify:
# ls /usr/share/snmp/mibs
exit the telegraf container
# exit
for troubleshooting purposes you can run this command
$ docker logs grafana
for troubleshooting purposes you can run this command
$ docker logs request tracker
Verify you can use rt Python library from saltstack master
- Run this command to start a shell session on the saltstack master container
docker exec -it master bash
- on the saltstack master container, start a Python interactive session
# python

Use RT GUI to verify the ticket details you created previously with Python interactive session
Run this command to show system connections activity
jcluser@vMX-addr-4> show system connections
Run this command to check the sensors on Junos
jcluser@vMX-addr-4> show agent sensors
The Junos packages openconfig and na telemetry are required for Openconfig telemetry.
Starting with Junos OS Release 18.3R1, the Junos OS image includes them, therefore, you do not need anymore to install them separately on your device.
If your devices are running an older Junos release, you need to install them separately.
Run this command to validate your Junos devices are using these 2 packages:
jcluser@vMX-addr-4> show version | match "Junos:|openconfig|na telemetry"
Run these commands to verify your Junos devices are running an appropriate configuration for snmp and openconfig telemetry
jcluser@vMX-1> show configuration snmp | display set
jcluser@vMX-1> show configuration system services extension-service | display set
jcluser@vMX-1> show configuration system services netconf | display set
Run this command to show YANG packages installed on Junos:
jcluser@vMX-1> show system yang package
Run this command to list YANG modules available on Junos:
jcluser@vMX-1> file list /opt/yang-pkg/junos-openconfig/yang/
Run this command to know which reference of a YANG module is used on a Junos device.
Example with openconfig-bgp-neighbor.yang YANG module
jcluser@vMX-1> file more /opt/yang-pkg/junos-openconfig/yang/openconfig-bgp-neighbor.yang
Run this command to understand which YANG deviations are used on a Junos device:
jcluser@vMX-1> file more /opt/yang-pkg/junos-openconfig/yang/jnx-openconfig-dev.yang
Run this command to check the salt-master service status
docker exec -it master service salt-master status
Run this command to check the salt-minion service status
docker exec -it minion1 service salt-minion status
Run this command to list the keys accepted by the master
docker exec -it master salt-key -L
Run this command to validate minion configuration
docker exec -it minion1 more /etc/salt/minion
Run this command to validate master configuration
docker exec -it master more /etc/salt/master
Run this command to validate proxy configuration
docker exec -it minion1 more /etc/salt/proxy
Run these commands to validate master <-> minion communication
docker exec -it master salt minion1 test.ping
docker exec -it master salt "minion1" cmd.run "more /etc/salt/minion"
Run these commands to validate master <-> proxies <-> junos devices communication
docker exec -it master salt 'vMX*' junos.cli 'show chassis hardware'
to watch the event bus, start a shell session on the master and run this command:
docker exec -it master bash
salt-run state.event pretty=True
