How To Install Cacti on Debian 10

Cacti is a complete network graphing solution designed to harness the power of RRDTool‘s data storage and graphing functionality. Cacti provides a fast poller, advanced graph templating, multiple data acquisition methods, and user management features out of the box. All of this is wrapped in an intuitive, easy to use interface that makes sense for LAN-sized installations up to complex networks with thousands of devices.

Features

Graphs

Unlimited number of graph items can be defined for each graph optionally utilizing CDEFs or data sources from within cacti.

Automatic grouping of GPRINT graph items to AREA, STACK, and LINE[1-3] to allow for quick re-sequencing of graph items.

Auto-Padding support to make sure graph legend text lines up.

Graph data can be manipulated using the CDEF math functions built into RRDTool. These CDEF functions can be defined in cacti and can be used globally on each graph.

Support for all of RRDTool’s graph item types including AREA, STACK, LINE[1-3], GPRINT, COMMENT, VRULE, and HRULE.

Data Sources

Data sources can be created that utilize RRDTool’s “create” and “update” functions. Each data source can be used to gather local or remote data and placed on a graph.

Supports RRD files with more than one data source and can use an RRD file stored anywhere on the local file system.

Round robin archive (RRA) settings can be customized giving the user the ability to gather data on non-standard timespans while storing varying amounts of data.

I will try to install the latest Cacti version on my Debian 10 Server.

My hostname lab1.unixcop.com

Create Root Mysql password

mysql_secure_installation

Create cacti user abd cacti database

For the best performance of the database, you may add these settings

sudo vim /etc/mysql/mariadb.conf.d/50-server.cnf
Add the following under [mysqld]
[mysqld]
……..
collation-server = utf8mb4_unicode_ci
character-set-server = utf8mb4
max_heap_table_size = 128M
tmp_table_size = 64M
join_buffer_size = 64M
innodb_file_format = Barracuda
innodb_large_prefix = 1
innodb_buffer_pool_size = 1GB
innodb_buffer_pool_instances = 10
innodb_flush_log_at_timeout = 3
innodb_read_io_threads = 32
innodb_write_io_threads = 16
innodb_io_capacity = 5000
innodb_io_capacity_max = 10000

Restart the database to activate the new settings .
