script or report to list/display route table

  • 1.  script or report to list/display route table

    Posted 17 days ago
    Is there some way in space to report on the route table for a device or gather the information to at least report on?

    Hi Mark,

    Can you please give more insights on what is that you are trying to achieve? And i believe you are talking about Junos Space, right?

    Thanks,
    Adrian.

    Correct, Junos Space.  I want to get the route table on a device and run a report on it or at least get sent/saved somewhere in a readable format.

    Hi Mark,

    There is an option to put a slax script in Junos Space under - Image and Scripts, for your case you can yous this slax script found_here . Practicaly you stage the script on the device and execute and you will get a csv with the results. Hope this helps.

    Thanks,
    Adrian.

    Hi Mark,

    Under job id you have a button Export CSV:

    }

    Mark,

    If memory serves me correctly, when using a locally executed SLAX script within Junos Space, it doesn't like multiple <output>...</output>  entries that are generated by using expr jcs:output(...).

    Instead to get the output displayed I recall that it was better to define a single output block that captures all the required output and using jcs:printf(...) instead.  

    It's been a very long time since I last created any SLAX scripts to be executed via Junos Space, so I'll need to look into this some more once I have the opportunity to spin up a Junos Space instance and take a look in the lab.  Hopefully I'll have some time to take a look at this over the next few days so long as I can get something running in our lab.

    Also, note that you would still need to have the import and namespace declarations present in the SLAX script as per the original version, else you'll see errors such as the one you have seen already.

    e.g. 

    ns junos = "http://xml.juniper.net/junos/*/junos";
    ns xnm = "http://xml.juniper.net/xnm/1.1/xnm";
    ns jcs = "http://xml.juniper.net/junos/commit-scripts/1.0";
    ns ext = "http://xmlsoft.org/XSLT/namespace";
    
    import "../import/junos.xsl";​

    Anyway, I'll take a look at the original SLAX script and do a test conversion to something that can run within Junos Space just as soon as I can, but it may take a few extra days.

    Regards.

    OK, finally figured this out.  Attached is a conversion of the slax script that was described in an earlier post so that it can run as a local slax script within Junos Space.

    Now, this script still doesn't output the data in CSV format, although with some minor reworking of the printf statements you could get it to generate CSV data.

    However, if you are just looking at doing a conversion of say "show route <foo>" to a CSV format, you are probably better off just seeing if looking glass works best for you.  The table view can be exported to CSV, and it supports running commands against multiple devices. 

    Anyway, the SLAX script is attached, if you still need a SLAX script to output results in CSV then I can assist, but it would only output a csv string in the results window, you wouldn't get a packaged .zip archive etc.. unlike say with looking glass.

    The attached script would need to be renamed from a .txt file to a .slax file so that it can be imported into Junos Space.

    Regards.

    Hi Mark,

    OK, I took a look at the script and the following is a version that will execute within Junos Space as a locally executed script.

    However this script doesn't output results in CSV.  With a bit of tweaking it would be possible to output the data in CSV.  However, for this scenario, I would have thought it easier to use looking glass instead.  That has the ability to execute commands against one or more devices, and the output can be put into a list view, and then that can be exported to CSV.    The only issue is if you want a CSV structure that is different to that that is produced by looking glass.??

    Anyway, here is the script that I can install into Junos Space and execute against a single device.
