That depends on the difficulty to aquire this data. rrdtool is |
| 25 |
basically a database which allows round-robin storage (old data times |
| 26 |
out) combined with some statistical abilities -- and also has a |
| 27 |
graphing component. It's your job to e.g. set up cron jobs or daemons |
| 28 |
which feed the data into it. You would create databases for each |
| 29 |
monitored entity (or group of entities for the same concept) and then |
| 30 |
write data into it. Then, on the other side, you could e.g. call it to |
| 31 |
create graphs that are being served via CGI, written to the desktop, |
| 32 |
whatever. |
