New Parser show interface extensive

[albertguasch]

Hi,

I am trying to adapt the show interface media to a new one show interface extensive parser in order to get information about queues in each interface.

It Works fine for traffic-statistics and input/output errors but is not working for queue counters. I guess is because xpath is 2 level Deep.

Here an example

parser:
regex-command: show\s+interfaces\s+extensive\s+|\s+display\s+xml
matches:
-
type: multi-value
method: xpath
xpath: //[local-name() = 'physical-interface']
loop:
key: ./[local-name() = 'name']
sub-matches:
-
xpath: ./[local-name() = 'traffic-statistics']/[local-name() = 'input-bps']
variable-name: $host.interface.$key.input-bps
-
xpath: ./[local-name() = 'traffic-statistics']/[local-name() = 'input-pps']
variable-name: $host.interface.$key.input-pps
-
xpath: ./[local-name() = 'traffic-statistics']/[local-name() = 'output-bps']
variable-name: $host.interface.$key.output-bps
-
xpath: ./[local-name() = 'traffic-statistics']/[local-name() = 'output-pps']
variable-name: $host.interface.$key.output-pps
-
xpath: ./[local-name() = 'input-error-list']/[local-name() = 'input-errors']
variable-name: $host.interface.$key.input-errors
-
xpath: ./[local-name() = 'input-error-list']/[local-name() = 'input-drops']
variable-name: $host.interface.$key.input-drops
-
xpath: ./[local-name() = 'output-error-list']/[local-name() = 'output-errors']
variable-name: $host.interface.$key.output-errors
-
xpath: ./[local-name() = 'output-error-list']/[local-name() = 'output-drops']
variable-name: $host.interface.$key.output-drops
-
xpath: ./[local-name() = 'output-error-list']/[local-name() = 'output-drops']
variable-name: $host.interface.$key.output-drops
-
xpath: ./[local-name() = 'queue-counters']/[local-name() = 'queue-counters-queued-packets']
variable-name: $host.interface.$key.queue-counters-queued-packets

And the XML sample:

Hi Albert,

It seems you need to modify your xpath, could you please try something like

./[local-name() = 'queue-counters']/[local-name() = 'queue'][queue-number='0']/[local-name() = 'queue-counters-queued-packets']

or a simplified version

./[local-name() = 'queue-counters']/queue[queue-number='0']/queue-counters-queued-packets

Then if it works you should repeat the same for each queue-number (0-3)

Hi,

Now I the parser doesn't fail. No log error in the log file.
But not able to record an value. Any problema with the variable?

        -
            xpath: ./*[local-name() = 'queue-counters']/*[local-name() = 'queue'][queue-number='0']/*[local-name() = 'queue-counters-qu

eued-packets']
variable-name: $host.interface.$key.queue.queue-number.0.queue-counters-queued-packets
