Error: Can't locate perl510.dll

[kwhogster]

Nagios Core 4.3.4
Nsclient 4.3
Windows 10

Just restarted my Windows 10 Desktop VM and Nagios reports this warning on two checks

Error: Can't locate perl510.dll


Check Windows Temp Folder WARNING 11-14-2018 22:01:47 0d 0h 32m 58s 10/10 Error: Can't locate perl510.dll


Explorer WARNING 11-14-2018 22:28:58 0d 0h 33m 34s 20/20 Error: Can't locate perl510.dll


Any ideas?

Hi @kwhogster,

It's most likely a corrupt file or perhaps another program overwrote/deleted this file. Have you made any changes/installed new software since this problem started or is it possible to revert to previous VM snapshot?

1. What version of perl do you have installed?

2. What plugin within Nagios are you using for those checks?

Hello

No Perl installed on this desktop

My code

Code: Select all

define service{
        use                     generic-service
        host_name               hostname
        service_description     Explorer
        check_command           check_nrpe!check_explorer! -a explorer.exe
        servicegroups           explorer
        }
define service {
        host_name               hostname
        service_description     Check Windows Temp Folder
        check_command           check_winfile
        servicegroups           Windows Temp
        check_interval          60
        notification_interval   60
        use                     generic-service
        }


define command{
        command_name    check_winfile
        command_line    $USER1$/check_nrpe -H $HOSTADDRESS$ -t 120 -c check_winfile -a '--target c:\windows\temp --filter "size gt 1073741824" -delete'
}
define command{
        command_name    check_explorer
        command_line    $USER1$/check_procs -c 1:30 -C explorer
}

Ran sfc /scannow came back clean

I search for perl510.dll on another windows 10 desktop that has the exact same checks above and they work on that one. and the dll is not found anywhere on the one either.

Thanks

Hello kwhogster,

If these checks are working fine on the other Windows 10 systems, then I would compare the nsclient.ini file with those other systems. Double check the ini file for the correct check_winfile definition in the external scripts settings. Make sure the script exists on you this Windows system.

Also, can you review (or post) the nsclient.log file for errors.

Let me know if you get it resolved.

checked both nsclient.ini files they look the same

The files reside on both in the same folder.

On the problem computer I ran the command manually

C:\Program Files\NSClient++\scripts>check_winprocess
PROCESS OK - 119 process(es)|processes=119;;;

My nsclient log in the log do not see any problems with current dates. check_schtask was the only one I see and I fixed that recently.

Hi

I think i got it working now.

I installed activeperl 64 bit from perl.org site.

Then after a restarted the checks cleared and are working.

This was very strange and is still not explained.

We can lock this for now
