UNIX Solaris

Hello Everyone,

I need your expertise in creating script on how to automate sending of alert/notification of NAS Space and also File counts with the following requirements.

  1. Automatically send to assigned sysadmin if it crosses threshold level.
  2. Threshold is 80% utilization of the total capacity (e.g. 70GB used out of 100GB.

Thanks in Advance.

Build a script which gathers your the volume information of your NAS using SNMP.

Check your NAS documentation or NAS MIBs for the OID's to use.

If it would be a Linux box, something like:

snmpwalk -v2c -c <somecommuntystring> <somehost> hrStorage

would provide the required info.

Ofcourse SNMP needs to be enabled on your NAS.

If you have no idea about the OID's, run a full walk to find them.

snmpwalk -v2c -c <somecommuntystring> <somehost> .

Notice the dot "." at the end.

The SNMP output, in case of a walk, are indexed tables.

Combine "Description", "Size", "Used" or whatever in the script to calculate the used percentage for each volume.

Define a treshhold in your script and if the used percentage for a voulme exceeds the treshhold, send out an e-mail.

Run the script as a Cron job

=======

Or use some monitoring tool like Nagios. Nagios is capable to send out alerts by e-mail.
