Linux/SSH Bandwidth Event Monitor Reference Guide

notitie

Overview​

The Linux/SSH Bandwidth Event Monitor monitors bandwidth on your Linux/SSH devices. This event monitor connects to your Linux-based systems using SSH and collects bandwidth data. It is capable of measuring and recording the incoming, outgoing, and total bandwidth rates. Additionally, it offers filtering options to ignore selected interfaces that are not required for monitoring.

Use Cases​

This tool is particularly useful for:

  • Monitoring incoming, outgoing, and total bandwidth for your SSH/Linux devices.
  • Detecting systems that are using excessive bandwidth.

Monitoring Options​

Alert Levels​

  • Alert with [Info/Warning/Error/Critical]: Choose the level of alert for situations when the device cannot be contacted.

Bandwidth Thresholds​

  • Alert if the incoming bandwidth on any interface exceeds a specified value: Set alerting thresholds based on the incoming bandwidth rate.
  • Alert if the outgoing bandwidth on any interface exceeds a specified value: Alerts based on the outgoing bandwidth rate.
  • Alert if the total bandwidth on any interface exceeds a specified value: Use this option for alerting based on the total bandwidth rate.

Connection Details​

  • Connect on port number: While the default port for SSH connections is 22, you can specify a non-standard port if your servers use one.

Interfaces to Ignore​

  • Interfaces to ignore: Enter the names of the interfaces to ignore, separated by commas (e.g., "Realtek, Marvell"). Interface names can be a partial match. To see the indexes, leave this field blank and run the event monitor once. Check the resulting event history record to get a list of detected interface names.

Authentication and Security​

The account used for authentication must have interactive login rights via SSH and permission to run one of the following commands:

  • cat /proc/net/dev
  • netstat -b -i

Protocols​

Data points​
