How do I get the laser rx power value ?

[Maxat Abdugapparov]

How do I get the laser rx power value from MX480 using pyez-junos ? (cli:  show interfaces diagnostics optics  ge-5/0/0)

[Rick Sherman]

Hi Maxat,

To find the RPC of a command in JUNOS you can use <command> | xml rpc

Example:

show interfaces diagnostics optics xe-2/2/0 | display xml rpc

<rpc-reply xmlns:junos="http://xml.juniper.net/junos/14.1R2/junos">

    <rpc>

        <get-interface-optics-diagnostics-information>

                <interface-name>xe-2/2/0</interface-name>

        </get-interface-optics-diagnostics-information>

    </rpc>

    <cli>

        <banner></banner>

    </cli>

</rpc-reply>

You can also view the ouput of a command as XML

show interfaces diagnostics optics xe-2/2/0 | display xml

<rpc-reply xmlns:junos="http://xml.juniper.net/junos/14.1R2/junos">

    <interface-information xmlns="http://xml.juniper.net/junos/14.1R2/junos-interface" junos:style="normal">

        <physical-interface>

            <name>xe-2/2/0</name>

            <optics-diagnostics>

                <laser-bias-current>5.808</laser-bias-current>

                <laser-output-power>0.5290</laser-output-power>

                <laser-output-power-dbm>-2.77</laser-output-power-dbm>

                <module-temperature junos:celsius="24.9">25 degrees C / 77 degrees F</module-temperature>

                <laser-rx-optical-power>0.4208</laser-rx-optical-power>
....

So with this you can use the RPC On Demand function

https://techwiki.juniper.net/Automation_Scripting/010_Getting_Started_and_Reference/Junos_PyEZ/RPC_On_Demand

rsp = dev.rpc.get_interface_optics_diagnostics_information(interface_name='xe-2/2/0')

print rsp.findtext('.//laser-output-power')

0.5280

You may also find it helpful to build a table/view

(If I find some time, I'll try and build you an example table).

Thanks,

Hi Rick,

Can you show me example table view for me ?

My TableView not working properly

InterfDiagOpticsTable:

  rpc: get-interface-optics-diagnostics-information

  args:

    interface_name: '[afgx]e*'

  args_key: interface_name

  item: physical-interface

  view: InterfDiagOpticsView

InterfDiagOpticsView:

  groups:

    optics: optics-diagnostics

  fields:

    laserBiasCurr: laser-bias-current

    laserOutputPower: laser-output-power

    rxOptAvgPower: rx-signal-avg-optical-power

    rxOptAvgPowerDbm: rx-signal-avg-optical-power-dbm

I see only interface names, not selected fields

Hi Maxi,

You need to make a small change to your view.  Change the word "fields" to "fields_optics".  The designation of "fields" + "_" + <groupname> tells pyez how to map the XPaths together.  For more details please see this URL:

Hope this helps!
