Hey folks!
I've been asked to review a company's monitoring system (network side only, the servers are being delt with separately)
Currently these are the things being monitored:
- Availability of network devices (such as switches, routers, etc.)
- Availability of interfaces
- Percentage of routers maximum throughput utilized on average
- Percentage of switches maximum throughput utilized on average (port channels)
- Average memory and processor utilization of network devices
- Amount of traffic coming in and out of routers
Currently the throughput percentages warn at 75% (if over for 5 mins) and become critial at 90% This is the same for memory and processor utilization.
I am curious to what other people set as their thresholds. Also at what point would you consider upgrading the speed of a link? Is it when its at 75%+ all day, everyday for a month? or if its 75%+ every second day?
What are your thoughts and experiences?
