Cacti cannot normally monitor traffic exceeding MB

Article title: Cacti cannot normally monitor traffic exceeding MB. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

Modify the configuration in Cacti

On the Cacti management page, choose Console> Data Source.

Find the port to be modified (that is, the port with a traffic greater than MB), and change the Output Type ID to In/Out bits (64-bit counters) (originally In/Out bits ), modify Maximum Value to 1000000000

Note: Some machines may need to upgrade snmp

Because the SNMP version 5.1.2 of Red Hat Enterprise Linux AS release 4 (Nahant Update 4) does not support monitoring traffic larger than MB, the traffic is often greatly reduced. To solve this problem, we need to manually upgrade it.

Therefore, the most important thing to modify is Settings-> Paths, because it is still the path of the snmp program during the original installation, you need to modify the installation path of the new snmp program to ensure that the net-snmp-5.4.1 is used, the installation path of my snmp program is in/usr/local/bin, take the snmpwalk example, the new path is/usr/local/bin/snmpwalk.
