sorry i didnt mean these are better than any others they are just free and avail. to gather data via snmp and then graph the results.. i spent 20 minutes writting a long desc. of how they work and the damn website said my post was too long and lost everything so here is a quick synopsis
mrtg runs via perl and collects data via snmp and graphs it.. it is free and avail here

to gather what info your router supports use snmpwalk to get the data
ie

to gather what info your router supports use snmpwalk to get the data
ie
1) No need to manually create config files
2) RRD - Round Robin Database and MySQL - this allows historical and analytical (statistical views and graphs. It would also allow you to access the data yourself (from the DB) and use it for things like an automated utilization cap, etc.
3) Much nicer web based PHP interface for graaphs and admin
Cacti is also Free. It CAN be very difficult to get MRTG running in a windows environment. There is an alternative MRTG build called PRTG which is for windows.
Tools for understanding and troubleshooting TCP – IP _________________ Conventional wisdom among radio guys is that $1 spent on antennas is worth $10 spent on amplifiers. Solve RF problems with antennas to the greatest extent possible before increasing power.
Jperf is a free small Java program that provides a nice GUI interface on top of Iperf, which is included in the /Bin folder.
Jperf makes using Iperf a lot easier.
It allows a user to easily modify the various network factors (like TCP Window Size), auto-formats the command syntax for Iperf, and allows a user to run the command with the click of one button.
It has a better measurement status display and improved logging support.
Posted: Wed Mar 12, 2014 11:09 Post subject: Server Monitoring
Hello
Monitoring depends a lot on what you want to monitor.
It depends on what kind of architecture. If you have devices supporting Netflow, this could be very handy to identify bottlenecks or missues. There are just a few good tools for netflow under a low budget, try solarwinds or Pandora FMS.
For a mixed scope on monitoring: server, apps and networking, you have less tools, we use Pandora FMS for that reason, can manage netflow, snmp, wmi (for remote server monitoring) and agent based monitoring for unix & windows server.
