Check_drivespace question

[kwhogster]

Nagios Core 4.3.4
Nsclient 5.1.44

I would like to see check_drivesize show the Volume Label on Windows Servers.

the check returns the Drive Letter.

Code: Select all

# z-drive.proto
define service{
        use                     generic-service
        host_name               Hostnames
        service_description     Z:\ Drive Space
        servicegroups           disk_usage
        is_volatile             0
        check_period            24x7
        max_check_attempts      3
        check_interval          5
        retry_interval          1
        contact_groups          NT-admins
        notification_interval   120
        notification_period     24x7
        notification_options    w,u,c,r
        check_command           check_win_disk!Z
        }

Code: Select all

# Use for nrpe (Windows Server Check Disk)
define command{
        command_name    check_win_disk
        command_line    $USER1$/check_nrpe -A $USER5$/ca/anakin-ca.crt  -C $USER5$/nagios_server/nagios_server.crt  -K $USER5$/nagios_server/nagios_server.key -2 -P 8192 -H $HOSTADDRESS$ -t 30 -c check_drivesize -a drive=$ARG1$ "detail-syntax=%(drive) - Total: %(size) - Used: %(used) (%(used_pct)%) - Free: %(free) (%(free_pct)%)" show-all
        }

Thank you

@kwhogster, Can you run and show me the current output of the command that you have?
You may need to add the ${drive_or_name} to the detail-syntax portion.

[root@centos7x64 libexec]# ./check_nrpe -H 192.168.3.145 -c check_drivesize -a drive=C: 'warning=free<20%' 'critical=free<10%' show-all 'perf-config=*(unit:G)' detail-syntax='{${drive_or_name} ${free_pct}% free / ${size} total}' top-syntax='${status}: ${problem_list}'
OK: {C: 66% free / 451.93GB total}|'C: free'=301.82408G;90.38594;45.19297;0;451.9297 'C: free %'=67%;20;10;0;100

From my current command


I:\ Drive Space Notifications for this service have been disabled

Shows drive letter

I tried your check

/usr/lib64/nagios/plugins/check_nrpe -A /usr/local/nagios/certs/ca/anakin-ca.crt -C /usr/local/nagios/certs/nagios_server/nagios_server.crt -K /usr/local/nagios/certs/nagios_server/nagios_server.key -2 -P 8192 -H brandy -t 30 -c check_drivesize -a drive=i detail-syntax='{${drive_or_name} ${free_pct}% free / ${size} total}' top-syntax='${status}: ${problem_list}'

Drive Volumes Names

Thank you

[npolovenko]

@kwhogster, I see. In your command please change:

detail-syntax=%(drive)

to

detail-syntax=%(drive)%(name)

Or if you want to use my check instead:

/usr/lib64/nagios/plugins/check_nrpe -A /usr/local/nagios/certs/ca/anakin-ca.crt -C /usr/local/nagios/certs/nagios_server/nagios_server.crt -K /usr/local/nagios/certs/nagios_server/nagios_server.key -2 -P 8192 -H brandy -t 30 -c check_drivesize -a drive=i detail-syntax='{${name} ${drive}${free_pct}% free / ${size} total}' top-syntax='${status}: ${problem_list}'

[kwhogster]

that still did not provide the name

/usr/lib64/nagios/plugins/check_nrpe -A /usr/local/nagios/certs/ca/anakin-ca.crt -C /usr/local/nagios/certs/nagios_server/nagios_server.crt -K /usr/local/nagios/certs/nagios_server/nagios_server.key -2 -P 8192 -H brandy -t 30 -c check_drivesize -a drive=i detail-syntax='{${name} ${drive}${free_pct}% free / ${size} total}' top-syntax='${status}: ${problem_list}'


CRITICAL: { i:1% free / 2TB total}|'i: used'=1.97439TB;1.5999;1.79988;0;1.99987 'i: used %'=99%;80;90;0;100

I should be getting back archiver-4 which is the I:\ drive

[npolovenko]

@kwhogster, For some reason, this check gives me volume labels only when I include "drive=all-volumes".

[root@centos7x64 libexec]# ./check_nrpe -H 192.168.3.145 -c check_drivesize -a 'drive=all-volumes' 'warning=free<20%' 'critical=free<10%' show-all 'perf-config=*(unit:G)' detail-syntax='{${name} ${drive} ${free_pct}% free / ${size} total}' top-syntax='${status}: ${problem_list}'
CRITICAL: critical({AXIS D:\ 0% free / 172.326MB total}), {OS C:\ 66% free / 451.93GB total}|'C:\ free'=302.77672G;90.38594;45.19297;0;451.9297 'C:\ free %'=67%;20;10;0;100 'D:\ free'=0G;0.03365;0.01682;0;0.16828 'D:\ free %'=0%;20;10;0;100

Can you check if that's the case with your command as well?

/usr/lib64/nagios/plugins/check_nrpe -A /usr/local/nagios/certs/ca/anakin-ca.crt -C /usr/local/nagios/certs/nagios_server/nagios_server.crt -K /usr/local/nagios/certs/nagios_server/nagios_server.key -2 -P 8192 -H brandy -t 30 -c check_drivesize -a drive=all-volumes detail-syntax='{${name} ${drive}${free_pct}% free / ${size} total}' top-syntax='${status}: ${problem_list}'

That shows the volume name

So how do we get it on only one drive?

Thanks

Something like this for F

Code: Select all

still not seeing the label?

[scottwilkerson]

Sorry I missed that.
