Editing Check defrag probe not working on Nagios

Checking Defrag Probe not working on Nagios
------------------------------------------


We have a problem with WG-DC1 -Defragmentation.

Lets look on nagios machine

/usr/local/etc/nagios/objects $ vi service.cfg

/defrag

Command is : check_defrag ! “C1”

Lets go to command

$ vi command.cfg

Defrag command 

$USER1$|Check_nrpe3 -H $HOSTADDRESS$ -n -t 7200 -c check-defrag -a $ARG1$

(its not always easy to get the metrics from a windows machine and lets execute the command on nagios machine

$ /usr/local/libexec/nagios/check-nrpe3 -H dc1.wise.apoyar -n -t 7200 -c check_defrag -a c:


It is easy with NRPE.

Go to DC1 Server.

Start 

Services

Stop the NSClient++ Monitoring agent

Now we try running it manually 

Start

CMD(Admin)

We find the NSClient++ in the local disk this is the windows server which takes all the commands and requests from nrpe, browses them and keeps all the information about.

Local Disk --- Program Files – NSClient++--NSCP.

In Command Prompt

C:”\program Files”\NSClient++”

Nscp









Go to command prompt admin

C:\program files\NSClient++ > cd Scripts

C: \program files\NSClient++\scripts > check_defrag( this command is missing )

We need to get the contents from other any other server 

Go to folders

Search : \\dc\\

Network>dc>c$>programfiles>NSClient++>Scripts

(this script folder contains pre installed scripts and custom scripts , Copy them)

Go back to previous folder

Local disk>program files> NSClieent++>scripts folder 

Paste it

(skip files which are same now we can see check defrag script in the folder)

Now we try running the command

C:\ program files\NSClient++\scripts > check_defrag.exe C:

a dialogue box displays with some message(the following feature couldn’t be installed
.NET Framework 3.5(includes >NET 2.0 and 3.0)

We need to install .NET Framework

Start> server manager(need to wait until it finish the loading)>manage>add roles and features>server selection(next)>server roles>features (.NET Framework3.5)>confirmation.

Note : if you try to install  .NET Framework 3.5 it would throw an error for windows) Specify an alternate source path

Go to folder

This PC > DVD Drivers> sources>sxs

Copy the path and paste as alternate path 

Click Install

Close after completes the installation

Now if we try to run the command 

C:\ program files\NSClient++\scripts > check_defrag.exe C:

It will run without any error –

We need to restart the services of NSClient++ after defrag completes without fail.






Let go back to Nagios machine and run the command.

$ /usr/local/libexec/nagios/check-nrpe3 -H dc1.wise.apoyar -n -t 7200 -c check_defrag -a c:

(Now we can see the services run for defragmentation)

Now we go to nagios

WG DC2 > Defragmentation > Reschedule the next check (Manually) > it will take some time and the issue get resolved.
