Netapp Cluster Mode Monitoring using Nagios Nagios-Cdot-Netapp Plugin

Monitoring storage usage / performance / utilization of space is more important, if something went wrong on the SAN / NAS dependent applications will also fail. To avoid we should continuously monitor the storage devices. Manually monitoring is not an good idea / humanly not possible. Netapp Cluster Mode Monitoring Using Nagios Nagios-Cdot-Netapp Plugin Step by step Guide.

 Netapp Cluster Mode Monitoring using Nagios 

Even If you use Nagios Core completely free open source application will work

Download Plugins Keep it ready

Also Download Netapp SDK file required login to Netapp Mysupport Site

Copy both the files to Linux and extract them using unzip <File Name> 

[root@Ark-Nagios netapp-cdot-nagios-master]# ./check_cdot_aggr.pl
Can't locate NaElement.pm in @INC (@INC contains: /usr/lib/netapp-manageability-sdk/lib/perl/NetApp /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /usr/local/lib64/perl5/NaServer.pm line 34.

Before placing Netapp SDK stuff to /usr/lib/ path you will see above error. After extracting SDK file just copy every thing to /usr/lib/ example provided below

[root@Ark-Nagios ~]# mv netapp-manageability-sdk-5.6 /usr/lib/netapp-manageability-sdk

Execute commands manually from Nagios Server and check status

To ensure commands are working by running manually. 

[root@Ark-Nagios netapp-cdot-nagios-master]# ./check_cdot_aggr.pl --hostname 192.168.2.20 --username Username --password Password --warning 80 --critical 90
CRITICAL: aggr1_SAS_ARK_NA01 (93%), aggr1_SAS_ARK_NA03 (90%), aggr1_SAS_ARK_NA04 (66%), aggr1_SATA_ARK_NA02 (63%), aggr2_SAS_ARK_NA01 (59%), aggr2_SAS_ARK_NA03 (88%), aggr3_SAS_ARK_NA01 (33%), aggr4_SAS_ARK_NA01 (7%), root_ARK_NA01 (96%), root_ARK_NA02 (95%), root_ARK_NA03 (95%), root_ARK_NA04 (95%)

As per above output commands are working fine as expected, let move them to plugin directory and configure commands

[root@Ark-Nagios netapp-cdot-nagios-master]# cp * /usr/local/nagios/libexec/

Configure Commands in commands.cfg file plugins Nagios-Cdot-Netapp

[root@Ark-Nagios ~]# vi /usr/local/nagios/etc/objects/commands.cfg

Generate / Define your Host config File for Monitoring

Using above command names, have to define your host config file for monitoring checks

Host definition, PING and SSH service monitoring config below

Define All Aggregates by replacing Aggregate name, copy definition paste it number of times.

define service{

 That’s it your Nagios Core Server is monitoring Netapp Cluster Mode Monitoring Filers continuously and send’s you an alerts when something CRITICAL / WARNING usage. 

Conclusion: 

Don’e be afraid when you get NaServer.pm file is missing error, Download Netapp SDK and copy the same to /usr/lib path. Using Nagios Core Completely free open source will save lot of money and Best monitoring tool for enterprise. Netapp Cluster Mode Monitoring

    Hi,
    I tried your tutorial in order to monitore cDOT NetApp, I have the following error when I try the command line :

    UNKNOWN: Failed to get the hostname corresponding to the server: xxxxxxxxxxxxxx. Please provide a fully qualified domain name of the server or use HTTP 1.0

    I tried the SVM ip address and hostname. Both ping from Nagios.
    Have you any idea ?
    Thanks

      Please post command output here.

    Hi Coursty,

    What your Typing on the command line and Command Setup is completely require change

    /usr/local/nagios/libexec/check_cdot_volume.pl –hostname $HOSTADDRESS$ –username UserName –password Password –size-warning 95 –size-critical 97 –inode-warning 95 –inode-critical 97 –volume $ARG1$ –perf

    • Crousty says:

      Hi,

      I have the same error ;(

      Command Line /usr/lib/nagios/plugins/check_cdot_volume.pl -hostname xx.xx.xx.xx –username admin –password xxxxxx –size-warning 95 –size-critical 97 –inode-warning 95 –inode-critical 97 –volume public –perf
      Output UNKNOWN: Failed to get the hostname corresponding to the server: xx.xx.xx.xx. Please provide a fully qualified domain name of the server or use HTTP 1.0
      Status UNKNOWN

      I really don’t understand. I have many problem to monitore the cDOT storage. I only want to monitore the volume usage. It worked before with 7-Mode but not CDot with SVM.
