Strange results from a check_nrpe command

Hi, I'm at V 5.5.2 64-bit VM CentOS7

Some commands sent to the same server via check_nrpe seem to work fine, some work but display these results:

send: reset nghttp2_active_outbound_item

send: aob->item = 00000000

recv: connection recv_window_size=0, local_window=65535

stream: adjusting kept idle streams num_idle_streams=0, max=100

recv: [IB_READ_FIRST_SETTINGS]

recv: [IB_READ_HEAD]

recv: payloadlen=18, type=4, flags=0x00, stream_id=0

recv: SETTINGS

recv: [IB_READ_SETTINGS]

recv: readlen=6, payloadleft=12

recv: [IB_READ_SETTINGS]

recv: readlen=6, payloadleft=6

recv: [IB_READ_SETTINGS]

recv: readlen=6, payloadleft=0

recv: [IB_READ_HEAD]

recv: payloadlen=4, type=8, flags=0x00, stream_id=0

recv: WINDOW_UPDATE

recv: [IB_READ_NBYTE]

recv: readlen=4, payloadleft=0, left=0

stream: adjusting kept idle streams num_idle_streams=0, max=100

stream: adjusting kept idle streams num_idle_streams=0, max=100

send: end transmission of client magic

send: reset nghttp2_active_outbound_item

send: aob->item = 00000000

send: next frame: payloadlen=12, type=4, flags=0x00, stream_id=0

send: start transmitting frame type=4, length=21

stream: adjusting



Any ideas?

Earl

Hello, @Bitflogger. Where do you see this output? In the check result on the Nagios home page? Can you share the service check command?

Here are some screen prints. On the target end, it runs a vugen script through NSClient acting as a NRPE server.
Some similar services work as expected. More than one exhibits the results I asked about.

We would need to see what the plugin/command check_vugen does on the other side, please attach it.

Hello,

I have it working running on a different server , with a lower version Windows OS, still initiated the same way from Nagios XI, so that indicates its not NagiosXI.

On the other side, I have a PERL program that runs a VuGen script, parses the output, then writes selected output to a log file after displaying the output for NRPE.

The output in the log file is as expected, so I cannot account for where the text seen from NagiosXI comes from.

Lets keep the call open for a short time, in case I can update it with useful info from our trouble-shooting.

Thanks!

This is a problem with the application on the other side. Please lock this case.
