Hello, i had this trouble to.
to resolve this, i had to change the centreon_plugins.exe.
i took an old version then without almost changing the ini file, it worked
try the version 20210427 from this build github.com/centreon/centreon-nsclient-build/releases/tag/20210518194507
Bonjour,
Après des tests croisés, je m'aperçois que depuis la version Centreon Plugins release 2022050400000. Les tests avec le plugin Veeam NSClient++ NRPE renvoi très souvent des erreurs "CHECK_NRPE: Receive header underflow - only 0 bytes received (4 expected).". Le problème c'est que les version en deça ne contiennent pas le mode Repositories. C’est un problème.
Est-ce obsolète pour les développeurs ? ou un oublie ?
Hello,
Thank you all for your patience, we have taken note of the problem and we will implement the strategy to address the issue in the best delay. Do not hesitate if you have any additional information or element to bring them to our attention.
Hi all,
If the issue comes from the plugin, then maybe we can get more information by runnin it directly on the Windows server.
Can you run this command?
"C:\Program Files\Centreon NSClient++\scripts\centreon\centreon_plugins.exe" --plugin=apps::backup::veeam::local::plugin --mode=job-status --filter-name="" --filter-start-time="" --filter-end-time="86400" --filter-counters="" --ok-status="" --warning-status="" --critical-status="%{is_running} == 0 and not %{status} =~ /Success/i" --warning-long="" --critical-long="" --verbose --debug
Feel free to run it several times and send the output here. It may help us a lot in the troubleshooting process.
Bonjour,
voici ce que me renvoi la commande en local.

Can you run it in your powershell console and post the results here?
It may behave differently with or without the Try/Catch, so try a second run in a second PowerShell console with this:
$culture = new-object "System.Globalization.CultureInfo" "en-us"
[System.Threading.Thread]::CurrentThread.CurrentUICulture = $culture
function Escape-JSONString($str) {
if ($str -eq $null) {return ""}
$str = $str.ToString().Replace('\\','\\\\').Replace('"','\"').Replace("`n",'\n').Replace("`r",'\r').Replace("`t",'\t')
return $str;
}
function ConvertTo-JSON-20($maxDepth = 4,$forceArray = $false) {
begin {
$data = @()
}
process{
$data += $_
}
end{
if ($data.length -eq 1 -and $forceArray -eq $false) {
$value = $data[0]
} else {
$value = $data
}
if ($value -eq $null) {
return "null"
}
$dataType = $value.GetType().Name

Hi @SavCent,
Thank you for your answer. I’m trying to get help from colleagues since we have reached the limits of my skills in PowerShell (they’re pretty low).
Hello same problem here:
CHECK_NRPE: Receive header underflow - only 0 bytes received (4 expected).
And trying on the host directly with the plugin:
C:\Program Files\Centreon NSClient++>"C:\Program Files\Centreon NSClient++\scripts\centreon\centreon_plugins.exe" --plugin=apps::backup::veeam::local::plugin --mode=job-status --filter-name="" --filter-start-time="" --filter-end-time="86400" --filter-counters="" --ok-status="" --warning-status="" --critical-status="%{is_running} == 0 and not %{status} =~ /Success/i" --warning-long="" --critical-long="" --verbose --debug
UNKNOWN: Command too long to execute (timeout)…
Using VBR V12….
Any idea is welcome :)
where is the doc on the filters part ?
--filter-name="" --filter-start-time="" --filter-end-time="86400" --filter-counters="" --ok-status="" --warning-status="" --critical-status="%{is_running} == 0 and not %{status} =~ /Success/i" --warning-long="" --critical-long=""
how can i know how this filters works ?
parse all the return of Get-VBRBackupSession is not a good idea (thousand of lines here) it’s would be better if we can take the last 3 months for example. (not sure it’s possible)
