What is cacti?

To put it rudely, it is a monitoring tool, which can not only monitor a single machine, but also complete the monitoring of the cluster! So if you do a performance test and want to monitor the cluster, ask the operator for an account to see it. Don't think about it by yourself. It's all ready-made.

Cacti installation

Yum install rrdtool

Yum install net-snmp net-snmp-libs net-snmp-utils

Vi / etc/snmp/snmpd.conf

In this way, you can monitor it. Most operators have already done this. You only need to apply for an account and know which machines to monitor the services on.
