Frequently-seen problem sets using Cacti

Article Title: FAQ set frequently seen when Cacti is used. Linux is a technology channel of the IT lab in China. Some basic categories, such as desktop applications, Linux system management, kernel research, embedded systems, and open-source systems, were previously solved by myself. At that time, I remembered that after a long time, when we re-install cacti on a new machine, we forget to modify it in advance, causing unnecessary troubles.

1. Generally, the image's Traffic Statistics description is | host_description |-Traffic-| query_ifName | described in this form. For Huawei devices, Gi is displayed as GigabitEthernet, this may cause the module number to be followed and the port cannot be displayed. For example, if GigabitEthernet4/3/2 is displayed as GigabitEthernet, the solution is as follows:
Console-> Settings-> Visual-> Maximum Field Length: The default value is 15. If it is changed to 30, it will be OK.
The maximum number of characters to display for a data query field.

2. If the problem persists when the Traffic is greater than 800 Mbits/s, modify Data Templates-> Interface Traffic-> 1 before creating the graph: traffic_in-> Maximum Value Use Per-Data Source Value is 100000000 by default, and then add a few more zeros. Similarly, 2: traffic_out should be modified, it is best to modify it before creating a new graph using new graph. Otherwise, it may be difficult or even unable to work properly.
