Overview

The Linux/SSH File System Event Monitor is designed to help you monitor the status and content of files on your Linux-based systems. It includes options for monitoring file size, timestamps, and can event check the file on multiple runs while only looking at new content that was added since the last run.

Use Cases

• Detecting when file systems are running out of space

Monitoring Options

This event monitor provides the following options:

Check the following file systems/mount points

Enter the mount points that will be checked by the event monitor.

Alert with [Info/Warning/Error/Critical] if the SSH server is unreachable

Use this option to control whether or not you will be notified if the event monitor is unable to establish an SSH connection.

Alert if file systems have less than a specified amount of space available.

This option lets you define thresholds for alerts based on the amount of space available on each file system.

Alert if file systems are more than a specified percentage full

This option is similar to the previous one but it alerts based on how full the file system is when measured as a percentage.

Show the data retrieved in all notifications

With this option enabled the event monitor will include a list of all detected file systems and their available space.

Connect on port number

The default port for SSH connections is 22, but if your servers are using a non-standard port you can specify it here.

Wait for a response for [#] seconds

This value controls how long the event monitor will wait for a response from the SSH server. The default value is best for most situations but you can increase or decrease it if you wish.

Authentication and Security

The account used for authentication must have interactive login rights via SSH. It also must have permission to run the following command:

• df -k

Protocols
