Hi all,

I am inspired on cacti evaperf to monitor HP EVA Storage Array and i wrote an ini file for check_wmi_plus plugin. You can use it with Nagios, Shinken, Centreon Engine, Icinga…It’s a free and easy solution to monitor the HP EVA Storage Array

So I suppose check_wmi_plus plugin is installed on your monitoring engine and “Command View EVA” is installed and working on Windows Server.

The WMI Class used :

• Win32_PerfRawData_EVAPMEXT_HPEVAPhysicalDiskGroup
• Win32_PerfRawData_EVAPMEXT_HPEVAHostPortStatistics
• Win32_PerfRawData_EVAPMEXT_HPEVAHostConnection
• Win32_PerfRawData_EVAPMEXT_HPEVAStorageArray
• Win32_PerfRawData_EVAPMEXT_HPEVAStorageController

You can test the “HP WMI Storage Providers” service is running

/bin/wmic -U "login"%"password" //Host 'Select Name from Win32_PerfRawData_EVAPMEXT_HPEVAStorageController'

If your wmic command gets you this :

ERROR: Retrieve result data.

Solution :

Stop Winmgmt service
Restart HPWMISTOR service
Start Winmgmt service

So, here my config file ini for check_wmi_plus : checkhpeva.ini

Save checkhpeva.ini file in check_wmi_plus.d directory. FYI, I dont want to be able the test on warn/critical criteria. it is an improvement to do

Create Nagios command :

define command{
  command_name                    check_hpeva_hostconnection
  command_line                    $USER1$/check_wmi_plus.pl -H $HOSTADDRESS$ -u "$ARG1$" -p "$ARG2$" -m checkhpeva -s allhostconnection -a $ARG3$
  ;$ARG1$                         login
  ;$ARG2$                         password
  ;$ARG3$                         physicaldiskgroup
}

define command{
  command_name                    check_hpeva_hostportstatistics
  command_line                    $USER1$/check_wmi_plus.pl -H $HOSTADDRESS$ -u "$ARG1$" -p "$ARG2$" -m checkhpeva -s hostportstatistics -a $ARG3$
  ;$ARG1$                         login
  ;$ARG2$                         password
  ;$ARG3$                         hostportstatistics
}

define command{
  command_name                    check_hpeva_physicaldiskgroup
  command_line                    $USER1$/check_wmi_plus.pl -H $HOSTADDRESS$ -u "$ARG1$" -p "$ARG2$" -m checkhpeva -s physicaldiskgroup -a $ARG3$
  ;$ARG1$                         login
  ;$ARG2$                         password
  ;$ARG3$                         physicaldiskgroup
}

define command{
  command_name                    check_hpeva_storagearray
  command_line                    $USER1$/check_wmi_plus.pl -H $HOSTADDRESS$ -u "$ARG1$" -p "$ARG2$" -m checkhpeva -s storagearray -a $ARG3$
  ;$ARG1$                         login

}

define command{

  command_line                    $USER1$/check_wmi_plus.pl -H $HOSTADDRESS$ -u "$ARG1$" -p "$ARG2$" -m checkhpeva -s storagecontroller -a $ARG3$
  ;$ARG1$                         login
  ;$ARG2$                         password
  ;$ARG3$                         storagecontroller
}

define command{
