Specific introduction of cacti and adding monitoring nodes

After logging on to the Cacti page, you can see the Console and Graphs tabs in the upper-left corner, Consle represents the console, where you can do all the configuration operations, while graphs is used to view the performance image interface for all servers:

The Consle menu commands are explained as follows:

create--

New graphs--to create an image

management--

Graph management--Image Management. Delete here, copy the image, and create the image automatically. If you have special needs, such as merging data from several images on an image, you can also create an image here manually.

Graphs trees--image tree. In the graphs interface, images or devices are displayed in a tree-like structure.

Data source--manages the rrd file. Generally no modification is required, cacti automatically creates an RRD file.

To create a monitoring node:

Then just fill in some basic information: the following:

Description: That's the description of the surveillance project.

Hostname: Is the host IP to monitor

Host Template: Select Ucd/net SNMP Host

SNMP version Select version 2, and then click the Create button in the lower right corner when you are finished:

After clicking, the following screen will appear:

Then click Create graphs for this host in the upper right corner:

During this step, there may be a problem with the NIC option that does not occur, the workaround is as follows:

On the monitored client, proceed as follows:

[Email protected] ~]# vi/etc/snmp/snmpd.conf view SystemView included. 1.3.6.1.2.1.1 modified to: View SystemView in cluded. 1.3.6.1.2.1

Tick the small box on the right to select the item you want to monitor, then click the Create button in the lower right corner:

Then click Graphs trees on the console and then click Default trees and select Host as follows:

Then select the Graphs button on the Consle side as follows:

Then after a period of time, we can see that there is already data showing such as:
