QUESTION
I'm pulling data from a network switch and it comes out as a string like this.
...ANSWER
Answered 2021-Dec-06 at 22:47Going by the conversation on the chat, text parsing seems to be the only way forward. I copied the entire text and saved it on to a file because I assume you have the output of the command stored in a file. For the sake of length of answer though, I tried with running only a few ports instead of all 48. Also Note that this works only if every column has atleast one row with data. This fails if there is a column for which no port has any data
Instead of using readline, I used read() so that I could split it at \n. This essentially removed the \n at the end of each entry in lines when using readlines()
QUESTION
I have the following code to connect to the switch and run two commands and save them as CSV, but the issue is when I run it, it will create two files with a same result! both are the result of "Show Vlan" It's like it replaces the first command. Any idea how to fix?
...ANSWER
Answered 2021-Oct-03 at 04:53You've assigned both textfsm.TextFSM(template1) and textfsm.TextFSM(template2) into one variable re_table.
I assume, you wanted to assign them to different variables, such as re_table1 and re_table2

Hello Developer Community!
I'm currently working on developing some Ansible playbooks to manage Citrix NetScaler configuration and would like to ask for some help about the following.
I have the following configuration line what I would like to parse with TextFSM:
...ANSWER
Answered 2021-Feb-10 at 13:01You can use the expression -rule\s*(\"(\\\"|[^\"])*\") that will take only the quoted value for the argument -rule, the key changes are
- The pattern starts with
-rule, - the parts consumes a quote if it is escaped in the repeating group, and consume an additional final quote.

If you wanted to included unquoted parameters as well you could use -rule\s*(\"(\\\"|[^\"])*\"|\S+), where the \S+ represents characters up to next space.
QUESTION
I am trying to parse CLI output that has cascading elements using textfsm & python. Here is an example: Ref - https://github.com/google/textfsm/wiki/TextFSM
Using this example. How can I get the value of 'CPU utilization' for each Slot ?
...ANSWER
Answered 2020-Sep-23 at 20:09I consider there are two mistakes in your template:
- You should Record when you have all data.
- The Model value you are trying to match in the last line of RESlot state can be matched only after you passed the CPU utilization section in the input text. Please note that textfsm parses the file line by line.
You can use below template to get your data:
QUESTION
I am currently trying to set up a test with Netmiko and Textfsm in Windows 10, but no matter what path I try to setup the textfsm environment variable, it still doesn't pick it up and throws an error:
Valid ntc-templates not found, please install https://github.com/networktocode/ntc-templates and then set the NET_TEXTFSM environment variable to point to the ./ntc-templates/templates directory.
I tried setting the environment variable manually via system properties --> environment variables, but still get the same message. I tried absolute as well as relative paths and no go. Ideally a relative path as the template folder will alway be alongside the script calling it. It might be something simple but im totally missing it right now.

I need to parse this raw data in order to process it:
...ANSWER
Answered 2020-May-29 at 11:11I finally managed to do what I want.
My team wished to use Ansible for the formatting, so I had to improvise a bit.
I used ntc-ansible for that.
With the help of members of the NTC Slack, I finally got it working. Here's what I came up with:
A functionality that is very poorly documented on the TextFSM repo is that you can, in an index file, combine two templates that share a common "Key" attribute.
So I created two templates:

Very unusual one but I'm trying to match output from an SSH session that may collapse view and fall underneath the output required (like a collapsed column)...
