“DZUB-NON TRUL-PAR Tibetan word for computer, translates as finger pressing magic picture”

This is my first plug-in for Nagios. For my work we use as a NAS a EMC Clarion Device. So we wanted to get some statistics to see how much we are using this hardware (you have to pay a license for this service).

This is possible in two ways.

• One is thru the graphical interface (slow… very slow).


• The second is thru the help of Navicli - a component of the EMC software package that gives you the possibility to do some scripted operations on the Clarion devices.

So we choose the second part and for this check we used 2 machines - an intermediary machine and the Nagios server (this can also be done with one machine but for some security / resource reasons we chose this infrastructure).

First we do a one way ssh trust relation from the Nagios server to the other (called LOG-retainer). So we make sure that the Nagios machine can ssh on to the LOG-retainer without a password. A trap in which I felled is not to do this operation as the Nagios user. NB: If you fail to add the .ssh directory on the Nagios home directory the script will give errors.

After this step is completed it's time to deploy the first part of our monitoring script on LOG-retainer:

#!/bin/bash

if [ -e NaviStats.txt ]; then

rm NaviStats.txt

fi

/opt/Navisphere/bin/naviseccli -User administrator -Password password -Scope 0 -Address 192.168.99.1 analyzer -archiveretrieve -file temp.nar -overwrite y -v

/opt/Navisphere/bin/naviseccli -Address 192.168.99.1 analyzer -archivedump -data temp.nar -out monitor.csv -join -header n -object s -overwrite y

#cat monitor.csv | gawk -F "," ' { printf "%s %s %s %s %s\n", $1,$2,$5,$14,$17 } '

echo "Object Name Poll Time Utilization (%) Total Bandwidth (MB/s) Total Throughput (IO/s)"

NaviStatsA=`cat monitor.csv | gawk -F "," ' {if ($1 == "SP A") printf "%s %s %s %s %s\n", $1,$2,$5,$14,$17 | "tail -n 1" } '`

NaviStatsB=`cat monitor.csv | gawk -F "," ' {if ($1 == "SP B") printf "%s %s %s %s %s\n", $1,$2,$5,$14,$17 | "tail -n 1" } '`

printf "$NaviStatsA\n$NaviStatsB\n" > NaviStats.txt

cat NaviStats.txt

#cat monitor.csv

if [ -e temp.nar ]; then

rm temp.nar

fi

Copy this in to a new file and save it as monitor.sh and set also the execute flag for this file.

Check if it works correctly by executing sh monitor.sh

The output should be something as:

Launching create archive

Attempting to retrieve file from array

Retrieve is complete.

Object Name Poll Time Utilization (%) Total Bandwidth (MB/s) Total Throughput (IO/s)

SP A 05/27/2009 16:26:42 9.448161 37.165939 754.397801

SP B 05/27/2009 16:26:42 11.464435 44.153673 678.160153

Now we are going to the Nagios machine and copy the second script in to the plug-ins directory

#!/bin/bash

Now we are ready to start to edit the Nagios configuration file.

Create a new file called emc.cfg in which put this configuration:

###############################################################################

# emc.cfg - SAMPLE CONFIG FILE FOR MONITORING the EMC hosts

# Contains all the hosts, services, and

# host group definitions required to monitor the EMC devices.

#

# Last Modified: 17-04-2009.

# files that get installed with the Nagios quickstart guide.

define command{

command_name check_emc_sp

command_line $USER1$/check_emc_sp.sh $HOSTNAME$ $ARG1$ $ARG2$ $ARG3$ $ARG4$

}

Now we should be able to check the configuration and restart the Nagios service and see the new hosts with their services up and running. From experience I saw that the update is done very slowly so you should put the check interval of 15-40 minutes rather then 5 minutes. This is the fault of the Navicli client not of the script.

The script needs testing so this is not the final version.

I presume that the same commands are working well (or can be easily modified) also for CX5. We don't have the monitoring license for him so I could not make the tests to see that.

If you have comments / improvements please let me know.

So... These days I had a small problem with my ZA installation - I forgot my security settings password. So I have tried a lot of solutions from the net but only one worked (which came directly from the support team - thanks guys):

Paul: The ONLY way to remove a ZoneAlarm password that is forgotten,

Paul: corrupted, or will not work is to remove the database files associated with

Paul: TrueVector, as follows.

Paul: Please note that this will remove your program permissions and

Paul: Trusted Zone settings (so you may want to make note of them), but re-

Paul: establishing them is a simple process; you will be prompted again for

Paul: program access for all the applications that you use to access the local

Paul: network or Internet.

Paul: First we need to boot into Safe Mode, please follow these steps to do so.

Paul: 1.) Power down your computer.

Paul: 2.) Start the system, and immediately begin tapping the 'F8' key once

Paul: every

Paul: second.

Paul: 3.) You will get a startup menu; choose 'Safe Mode' by using the up/down

Paul: arrow keys.

Paul: 4.) Press Enter.

Paul: Once you have booted into Safe Mode, please continue.

Paul: 1.) If you have Windows XP, click Start -> My Computer. In Vista, go to

Paul: Start -> Computer

Paul: 2.) Double-click your C: drive, probably called local disk c:.

Paul: 3.) Double-click on the Windows or Winnt folder.

Paul: 4.) Double-click the Internet Logs folder.

Paul: 5.) Please delete the following files here:

Paul: - Backup.rdb

Paul: - Iamdb.rdb

Paul: 6.) Close this window, then right-click and empty the recycle bin.

Paul: 7.) Clear the registry entry with the steps below:

Paul: - Go to Start -> Run

Paul: - Type in regedit and press OK

Paul: - On the left find HKEY_LOCAL_MACHINE. Click on the plus next to this and

Paul: make it a minus.

Paul: - Find the SOFTWARE folder; click on the plus and make it a minus

Paul: - Find the Zone Labs folder; click on the plus and make it a minus

Paul: - Find the TrueVector folder; click on the plus and make it a minus

Paul: - Find the Store folder; click on it

Paul: - On the right, locate and left click on the 'upwval' entry

Paul: - Press delete and then say yes to the alert that pops up

Paul: 8.) Close this window, then restart the computer normally. Be sure to

Paul: answer any configuration screens you may receive once your system has

Paul: restarted.

Paul: NOTE - Links to sites other than ZoneAlarm.com are provided for the

Paul: convenience of our users. ZoneAlarm does not provide, and is not

Paul: responsible for, the content users may find on such sites.

And it worked like a charm for me. I mention that my ZA version is 8.0.059.000 (8.0.59.0).

Before you start this tutorial please make sure that your network responds to the same OID as here and that you have configured all the UPS-s to work with the snmp (note down your snmp community string). In my tests I used the standard powernet395.mib from APC and the rfc1628.mib for AROS.

First make sure that you activated the check_snmp command in the file commands.cfg. If you don't, add it as follows:

# 'check_snmp' command definition

define command{

command_name check_snmp

command_line $USER1$/check_snmp -H $HOSTADDRESS$ $ARG1$

}

So we will use this command with the following switches

check_snmp -H <ip_address> -o <OID> [-w warn_range] [-c crit_range] [-C community] [-s string] [-u units]

Add the corresponding templates (this is good if you want a service allocation by type or model) on the templates.cfg. Here is the example:

# Define a template for the UPS's that we can reuse

define host{

name generic-ups

use generic-host

check_period 24x7

check_interval 5

retry_interval 1

max_check_attempts 10

check_command check-host-alive

notification_period 24x7

notification_interval 30

contact_groups admins

register 0 ; DONT REGISTER THIS - ITS JUST A TEMPLATE

}

# Define a template for the AROS UPS's that we can reuse

define host{

name generic-aros

use generic-ups

hostgroups 007-ups-all,007-ups-all-aros

contact_groups admins

icon_image aros.png

icon_image_alt UPS_AROS

register 0 ; DONT REGISTER THIS - ITS JUST A TEMPLATE

}

# Define a template for the APC UPS's that we can reuse

define host{

name generic-apc

use generic-ups

hostgroups 007-ups-all,007-ups-all-apc

contact_groups admins

icon_image apc.png

icon_image_alt UPS_APC

register 0 ; DONT REGISTER THIS - ITS JUST A TEMPLATE

}

Create the new corresponding groups:

define hostgroup{

hostgroup_name 007-ups-all

alias UPS (all)

}

define hostgroup{

hostgroup_name 007-ups-all-aros

alias UPS (all AROS)

}

define hostgroup{

hostgroup_name 007-ups-all-apc

alias UPS (all apc)

}

Create a new configuration file (I named it ups.cfg) and add the entry to the Nagios main configuration file:

#Definitions for monitoring the UPS Devices

cfg_file=/usr/local/nagios/etc/objects/ups.cfg

Now we can start work on the configuration file. First we declare the hosts:

define host{

use generic-apc

host_name IT-UPS-APC

alias this is a standard apc ups

address 192.168.3.60 ; IP address of the device

}

define host{

use generic-aros

host_name IT-UPS-AROS

alias this is a standard aros ups

address 192.168.3.61 ; IP address of the device

}

Then we declare the services (first the generic services):

define service{

use generic-service ;

hostgroup_name 007-ups-all

service_description PING

check_command check_ping!200.0,20%!600.0,60%

normal_check_interval 5

retry_check_interval 1

}

# Monitor uptime via SNMP

define service{

use generic-service ;

hostgroup_name 007-ups-all

service_description Uptime

check_command check_snmp!-C Default_snmp_string -o sysUpTime.0

}

After we can make the UPS checks by device type:

- Se amesteca bine... (aka i se prezinta in 10 min userului ce face noul sistem)


- I se cere o nota pt Mojave (OAU 8.5.... extraordinar ce poate sa faca...)


- I se comunica loserului ca a "incercat" (i s-a prezentat) Vista.... Si surpriza ... Acesta spune ca i-a placut!

Acu' ca in orice studiu care se respecta (si care da bine la marketing) nu se dau date despre cei "sceptici" care din diverse motive nu le-a placut prezentarea (de ce anume nu le-a placut, etc...).
