KB1089: Monitoring Disk Space on UNC Mounted Drives using Monitoring Studio | Knowledge Base

Description

This article explains how to configure the Monitoring Studio KM to monitor the available disk space on network mounted drives.

To monitor the available disk space on network mounted drives, we need to combine an OS Command Analysis and Numeric Value Extraction.

From the PATROL Console, right-click on the main "Monitoring Studio" icon › KM Commands › New › Command Line Analysis...
Click Next
Specify DIR \\server\share as the command to be executed. server and share must respectively be replaced with your server and share names
Click Next
Leave the other fields to their default value and click Next
Provide appropriate display name and ID and click Finish. A new icon is created in the PATROL Console
Double-click the ReturnOutput item to display the command result; which is refreshed every 2 minutes by default.

To create a numeric value extraction:

Right-click the OS Command icon › KM Commands › New › Numeric Value Extraction… and click Next
Specify that you want to extract numeric values from the Lines matching the regular expression “bytes free” and click Next.
Specify that the numeric value is located before the string bytes free
In the Expected format pull-down list, select 100,000.00 and click Next
Leave the field unchanged and click Next
Have the value converted from bytes to GB:
1. In the Rescaling pull-down list, select Divide the value by
2. Type 1073741824
3. Click Next
Choose a valid label, specify that you need to set custom thresholds and click Finish. You will then be asked to set thresholds:
Select Value and click Next
Trigger a WARNING if value is lower than 10; 5 times in a row and an alarm if value is lower than 2; 1 time in a row
Click Set thresholds.

A new object is created in the PATROL Console and a Value graph is generated with the freebytes value coming from the output of our DIR command.
