Suggestions for a N/w Monitoring Tool
I am pretty new to UNIX networking as such and so would like to ask you which smnp tool should i use to monitor my network. These are the things that i would like the tool to report
1) Bandwidth usage for each site (there are multiple sites hosted in the same server).
2) Able to Check Log files
3) Possible Errors encountered by the server.
4) HTML or XML outputs
Thanks for your help in advance
