monitoring plugin check_storcenter

Last update: December 08, 2020

With this plugin you can do several checks on your EMC/Iomega StorCenter NAS.

The plugin successfully works on a px4-300r. Please let me know wheter or not it works for another model, too.

End of life warning

As I don't have any StorCenter devices around to test further development, this plugin is end of life. Use as is.

Download

Download plugin and save it in your Nagios/Monitoring plugin folder (usually /usr/lib/nagios/plugins, depends on your distribution). Afterwards adjust the permissions (usually chmod 755).

Community contributions welcome on GitHub repo.

Compatibility matrix

The plugin has been successfully tested on the following StorCenter devices:

• px4-300r: All checks work
• ix2/ix2-200: mem check does not work

# 'check_storcenter' command definition
define command{
command_name check_storcenter
command_line $USER1$/check_storcenter -H $HOSTADDRESS$ -U $ARG1$ -t $ARG2$ $ARG3$

Command definition in Icinga 2.x

object CheckCommand "check_storcenter" {
  import "plugin-check-command"

  command = [ PluginContribDir + "/check_storcenter.sh" ]

  arguments = {
    "-H" = {
      value = "$storcenter_host$"
    }
    "-U" = {
      value = "$storcenter_username$"
    }
    "-P" = {
      value = "$storcenter_password$"
    }
    "-t" = {
      value = "$storcenter_checktype$"
    }
    "-w" = {
      value = "$storcenter_warning$"

Service definition

Service definition examples in Nagios, Icinga 1.x, Shinken, Naemon

# Check StorCenter Disk
define service{
use generic-service
host_name nas1
service_description Disk Status
check_command check_storcenter!nagios!disk
}

# Check StorCenter Raid
define service{
use generic-service
host_name nas1
service_description Raid Status
check_command check_storcenter!nagios!raid
}

# Check StorCenter CPU
define service{
use generic-service
host_name nas1
service_description CPU Load
check_command check_storcenter!nagios!cpu
}

In the following example, the username 'nagios' is used and the check type is 'mem'. The thresholds are normal integers and represent the percentage of memory usage. A warning notification will be sent if the memory usage is higher or equal to 50%, a critical notification at 90%.

# Check StorCenter Memory (RAM)
define service{
use generic-service
host_name nas1
service_description Memory Usage
check_command check_storcenter!nagios!mem!-w 50 -c 90
}

# Check StorCenter Information
define service{
use generic-service
host_name nas1
service_description Information
check_command check_storcenter!nagios!info
}

Service object definition Icinga 2.x

# Check Storcenter Disk Status
object Service "Disk Status" {
  import "generic-service"
  host_name "nas1"
  check_command = "check_storcenter"
  vars.storcenter_checktype = "disk"
}

# Check Storcenter CPU Load
object Service "CPU Load" {
  import "generic-service"
  host_name "nas1"
  check_command = "check_storcenter"
  vars.storcenter_checktype = "cpu"
}
