Devices Graph
This module allows you to dynamically generate stacked interface graphs and much more.
Please note that NeDi's graphing feature was implemented as an addition to the discovery with lowest possible resource and maintenance cost in mind.
It will not graph those 5 minute peaks (unless you run NeDi every 5 minutes in very small networks), but provides a longterm view
of each and every interface. This translates to baselining and prediction of potential bottlenecks, instead of identifying erratic outbursts of any kind (You'd prefer using a tool like Cacti to monitor this instead).
- Select any top graphs if you wish to get the big picture on your network.
- Selecting a device will reveal its interfaces. You can choose several of them to be stacked dynamically (doesn't work for IF status!).
- Select several graph sources at once to correlate and investigate problems (e.g. CPU load, broadcasts on some interfaces of a device)
- System related graphs are CPU, Memory and Temperature and a custom graph for other values.
- Use double arrows to move start (top one), the whole graph (middle) or its end (bottom one) by weeks or single arrows for days. Click on a date icon to manually set a start or end time.
- If you can't live without degrees in Fahrenheit, adjust the setting in User-Profile.
- CPU and memory corresponds to System load and battery capacity on UPS units'.
If you use Cacti on the same host, you can integrate it into NeDi:
- Configure the cacti options in nedi.conf.
- Now you can add devices and interfaces to Cacti here in Devices-Graph.
- A cacti icon will be shown in Devices-Status, if the device is available in Cacti. Clicking on it takes you there.
