Managing System & Networks

As systems become more sophisticated we are loosing some of our deep understanding of system operations.

While most engineers and analyst are technically superior in many ways, we also miss the mark on understanding the underlying operation.

Managing a network is not vastly different than it was 20 years back but their are many more tool sets available. It's much quicker to get a system up and running. The challenge comes from interpreting the data to meaningful information.

I've seen many organizations depend on the Ping to get connectivity and response time information which is not inherently bad but understanding of what really happens is lost. Ping will tell you if the network card in a server is responding but that's about it. Great at letting you know there is not a line cut but terrible at telling you what's happening on the system. The Ping packet (ICMP) is designed to go to the network card where it is processed and sent back. It never reaches the CPU therefore the server could e completely locked yet responding to a ping.

A simple SNMP or WMI query will let you know the system is available. While doing the query one can get valuable information such as memory, CPU and disk utilization.

Just some thoughts from an older guy in the IT industry.

sward Some systems block the Ping (ICMP) Packet for security reasons, so it is not always the best method, but beyond that, you are correct, a good IT manager knows what tools are available and use them wisely, depending on the situation.

The systems in the banks are very complicated, and sometimes a simple bug brings down the whole banking system for a few hours.
