By default, only definite and possible leaks are considered as errors. You can use e.g. --errors-for-leak-kinds=all to have all leak kinds considered as errors:

@pchaigno is correct; you need to do vlan and tcp or, to catch both VLAN-encapsulated and non-VLAN-encapsulated TCP packets, tcp or (vlan and tcp).

• As of PowerShell 7.2, output from external programs is invariably decoded as text before further processing, which means that raw (byte) output can neither be passed on via | nor captured with >. See this answer for details.

• PowerShell's > redirection operator is effectively an alias of Out-File, and its default character encoding therefore applies.

In Windows PowerShell, Out-File defaults to "Unicode" encoding, i.e. UTF-16LE:

• This encoding uses a BOM (byte-order mark), whose bytes, if interpreted individually as ANSI (Windows-1252) bytes, render as ÿþ), and it represents most characters as two-byte sequences,^[1] which in the case of most characters in the Windows-1252 character set (which itself is a superset of ASCII) means that the second byte in each sequence is a NUL (0x0 byte) - this is what you're seeing.

Fortunately, in PowerShell (Core) 7+, all file-processing cmdlets now consistently default to (BOM-less) UTF-8.

To use a different encoding, either call Out-File explicitly and use its -Encoding parameter, or - as you have done, and as is generally preferable for the sake of performance when dealing with data that already is text - use Set-Content.

^{[1] At least two bytes are needed per character; for characters outside the so-called BMP (Basic Multilingual Plane), a pair of two-byte sequences is needed.}

Pandas read_json method needs valid JSON str, path object or file-like object, but you put string. https://pandas.pydata.org/docs/reference/api/pandas.read_json.html

Try this:

I don't know if you can do it with GetFromJsonAsync but using Newtonsoft.Json. You can craft a special convert that will check if the token is an array or an object. And deserialize to the appoprriate type.

Use process.kill() to terminate process. Afterwards do process.wait() to wait till it fully terminates. Example below.

I replaced your shell command with simple python's infinite-loop program. Just for the sake of working example that can be tested by all StackOverflowers.

In your case for loop is not necessary, also my shell command doesn't matter, these two modifications were done only for runnable example purpose.

Notice in second if that I used 'process' in locals() and process is not None, this check is necessary in order to have no error if process variable wasn't yet created, in this case you don't need to kill/wait anything, because there is actually nothing to be killed/waited because there is no process created yet. Also I set variable to process = None so that you never do a second kill again on already killed process.

The mentioned property page is likely to pull the data using IAMAnalogVideoDecoder and get_HorizontalLocked method in particular. Note that you might be limited in receiving valid status by requirement to have the filter graph in paused or running state, which in turn might require that you connect a renderer to complete the data path (Video Renderer or Null Renderer, or another renderer of your choice).

See also this question on Null Renderer deprecation and source code for the worst case scenario replacement.

DPDK counter rx_missed_errors infers these many packets were not processed which were received on the NIC. While Rx-no-mbuf represents the counters which showcase packets that were not DMA to CPU-Memory due to the absence of MBUF buffers. Hence the error is mostly in application logic either Spending too much time processing the packets or recursive processing on the same MBUF array after rx_burst.

[EDIT-1] Based on a couple of debugging attempts and pointers the issue is root caused to application logic. Summarizing the below

1. For incoming ARP requests the packets are processed and ARP reply is sent out on the same MBUF and rte_pktmbuf_free we called immediately right after rte_Eth_tx_burst - Issue Fixed
2. For IP packets, the IP header and UDP header are processed for the desired packet and necessary changes are made to the MBUF before transmission. - for certain conditions (count of packets) the logic enters to longer loops which stalls the function exit.

Note:

1. Fixing the above 2 issues seems to solve the issue.
2. Using DPDK-Pktgen to generate custom packets allows to narrow down specific code areas.

If we need a tidy version, instead of rbind, use bind_rows and then change the dcast to pivot_wider
