How to config plugin check_newest_file_age

[welbp00]

Hi,
How to config check_newest_file_age? I have got the command working from the command line:

./check_nrpe -H linux-server -c check_newest_file_age -a' -d "/waslog/cp_init /gpfs/fileSystemConnections55ONT/filesystemconnections6data/Search-bck/latest/" -w 7 -c 8 -t days'

nrpe.cfg looks like this:

command[check_newest_file_age]=/usr/lib64/nagios/plugins/check_newest_file_age -d $ARG1$ -w 7 -c 8 -t days

cfg file:

define command{
command_name check_newest_file_age
command_line /usr/lib64/nagios/plugins/check_newest_file_age -H '$HOSTADDRESS$' -c check_newest_file_age -d '$ARG1$'


define service {
use generic-service
host_name linux-server
check_interval 300
service_description Controle herstart- en backup-log
check_command check_newest_file_age!/waslog/cp_init/!/gpfs/fileSystemConnections55ONT/filesystemconnections6data/Search-bck/latest/

Output in Nagios:

(No output on stdout) stderr: execvp(/usr/lib64/nagios/plugins/check_newest_file_age, ...) failed. errno is 2: No such file or directory

What am i doing wrong in the cfg-files?

Please help.

Best regards, Paul

Do you get the same message if you remove the trailing / after cp_init? The command line version you say is working is different than what you are placing in the config.

check_nrpe -H linux-server -c check_newest_file_age -a' -d "/waslog/cp_init /gpfs/fileSystemConnections55ONT/filesystemconnections6data/Search-bck/latest/" -w 7 -c 8 -t days'


define service {
use generic-service
host_name linux-server
check_interval 300
service_description Controle herstart- en backup-log
check_command check_newest_file_age!/waslog/cp_init!/gpfs/fileSystemConnections55ONT/filesystemconnections6data/Search-bck/latest/

instead of

define service {
use generic-service
host_name linux-server
check_interval 300
service_description Controle herstart- en backup-log
check_command check_newest_file_age!/waslog/cp_init/!/gpfs/fileSystemConnections55ONT/filesystemconnections6data/Search-bck/latest/

Hi, @welbp00. You said this command is working?

Code: Select all

./check_nrpe -H linux-server -c check_newest_file_age -a' -d "/waslog/cp_init /gpfs/fileSystemConnections55ONT/filesystemconnections6data/Search-bck/latest/" -w 7 -c 8 -t days'

Combined with the definition you have in the nrpe.cfg file:

Code: Select all

command[check_newest_file_age]=/usr/lib64/nagios/plugins/check_newest_file_age -d $ARG1$ -w 7 -c 8 -t days

The final command that actually runs on the nrpe server looks like this:

Code: Select all

/usr/lib64/nagios/plugins/check_newest_file_age -d /waslog/cp_init /gpfs/fileSystemConnections55ONT/filesystemconnections6data/Search-bck/latest/" -w 7 -c 8 -t days -w 7 -c 8 -t days

This is incorrect because some arguments are repeating.

Here's the easier way to define everything.
On the nrpe server change the command to:

Code: Select all

command[check_newest_file_age]=/usr/lib64/nagios/plugins/check_newest_file_age $ARG1$

And on the nagios server your command will be:

Code: Select all

define command {
    command_name    check_nrpe
    command_line    $USER1$/check_nrpe -H $HOSTADDRESS$ -t 30 -c $ARG1$ $ARG2$
}

Your service will be:

Code: Select all

define service {
use generic-service
host_name linux-server
check_interval 300
service_description Controle herstart- en backup-log
check_command check_nrpe!check_newest_file_age! -a '-d "/waslog/cp_init /gpfs/fileSystemConnections55ONT/filesystemconnections6data/Search-bck/latest/" -w 7 -c 8 -t days'
}

Hi npolovenko,

i have used your settings, and it seems to be working just fine, I have to do some more tests.

I will let you know.

Thanks!!

Hi,
i am still testing, but i need some more info....

This check should only run on monday morning. I have found some info how to configure but i am not sure about some settings..

Now i have one basic_host.cfg with several different checks. They all should run every 5 minutes, 24x7.

Like this:

define host {
name system-host-basis
max_check_attempts 3
check_period 24x7
check_command check-host-alive
contacts nagiosadmin
notification_interval 60
notification_period 24x7
}

But this plugin (check_newest_file_age) should only run on monday morning.
Do i have to make an additional basic.cfg file, with different time-period settings or is there another way?
Also do i have to make an entry in timeperiods.cfg? And how should it look like?

Thx, regards,

Paul.

Could be something like this:

timeperiods.cfg:

define timeperiod{
timeperiod_name onlymondays
alias onlymondays
monday 00:00-09:00 ; Every Monday of every week
}

basic.cfg, section host config:

define host {
name linux-host-basis
max_check_attempts 3
check_period onlymondays
check_command ....
contacts nagiosadmin
notification_interval 60
notification_period onlymondays
}

What do i enter at check_command; check_newest_file_age?

[npolovenko]

@welbp00, Do you want the host check to only run on Monday as well? Or the host check needs to run every day, 24x7 with a 5-minute interval? You can use this config.

Code: Select all

define host {
  host_name  linux-host-basis
  alias  linux-host-basis
  address replace_with_host_ip_address
  max_check_attempts 3
    check_interval           5
    retry_interval           1
  check_period 24x7
  check_command check-host-alive
  contacts nagiosadmin
  notification_interval 60
  notification_period 24x7
}

define service {
use generic-service
host_name  linux-host-basis
check_interval 5
check_period onlymondays
otification_period onlymondays
service_description Controle herstart- en backup-log
check_command check_nrpe!check_newest_file_age! -a '-d "/waslog/cp_init /gpfs/fileSystemConnections55ONT/filesystemconnections6data/Search-bck/latest/" -w 7 -c 8 -t days'
}

The other checks run every day, including the host-check.
Online the check_newest_file_age should run on monday morning.

If you only want the service to run on Mondays you would add the following to the service definition

Code: Select all

check_period onlymondays

Hello, thnx for the help.

I have tried this:

define service {
use generic-service
host_name linux-server
check_interval 300
service_description Controle herstart- en backup-log
check_period onlymondays
notification_period onlymondays
check_command check_newest_file_age! -a '-d "/waslog/cp_init /gpfs/fileSystemConnections55ONT/filesystemconnections6data/Search-bck/latest/" -w 7 -c 8 -t days'
}

I have added this in the /etc/nagios/objects/timeperiods.cfg:

define timeperiod{
timeperiod_name onlymondays
alias onlymondays
monday 00:00-09:00 ; Every Monday of every week
}
Don't know if it was needed?

Nagios monitor report this: Next Scheduled Check: 05-13-2019 00:00:40
Next week monday, so that seems to be OKay.

I will do some more test, but it looks fine.

Thnx for the help people!

Regards,

Paul.
