| Course Outline |
Many devices support SNMP, including routers, switches, servers, workstations, printers and Uninterruptible Power Supplies (UPS).
What this means is you can use SNMP and monitor the health of your routers, servers and other pieces of network devices; which is fairly simple.
Before you get started anyway, you sure want to know what SNMP is
What do you or your organization get to benefit when using SNMP?
If you have a device that supports SNMP, how can you tell they are configured properly?
When does MRTG come into play, and what is it anyway?
You want to see trends at a glance; graph memory usage, load average, CPU performance and more. How can you use MRTG to make this possible? Sometimes a picture is worth a thousand words. |
