When asking about a non-standard plugin, it's very useful to also include where
you got that plugin. How it does what it does is very relevant to your question.

How does it determine this?

Much more likely is that the script is using something like '/bin/du' to
calculate the size of the directory and that it is sometimes taking longer than
you've told nagios to wait to do so. That doesn't really surprise me for a
directory of that size.

Look at your check_nrpe command definition. If it specifies a timeout value
(-to), increase it as needed. If it doesn't, add one. Also check the value of
service_check_timeout in nagios.cfg. It should be higher than the check_nrpe
timeout.
An even better solution is to make that directory it's own partition. Then you
can use check_disk, which will be nearly instantaneous, to determine the size
of the directory.

[Nagios-users] Improving performace of the check_folder_size script
Hi there --
I am running Nagios 3.1.2 with the nrpe 2.12 client. One of the scripts that I
am using is the
check_folder_size script. The Nagios server is on one subnet, while the client
is on another.
The connection between the two is via a 10GB WAN connection. The script is
configured on
the client to send warnings when the folder in question reaches 500 gigabytes.
The entire
disk that the folder is on is four terabytes.
The script appears to be doing its job pretty well, but I notice that
occasionally I will get
timeout issues with the script. I suspect the configuration of the script on the
Nagios server is
the cause, and I wanted to get feedback as to the best settings to have for the
script. The current
configuration is shown below:
# Service definition
define service{
use generic-service ; Name
of service template to use
host_name
service_description Folder Size Active 1
is_volatile 0
check_period24x7
max_check_attempts 1
normal_check_interval1440
retry_check_interval720
contact_groups linux-admins
notification_interval 1440
notification_period 24x7
notification_optionsw,u,c,r
check_command check_nrpe!check_folder_size1
}
Does anyone have any suggestions as to what settings would be better here?
Thanks.
