Debian: Install cacti-Debian, the Linux release technology. For more information, see the following. I. Comparison of mrtg and cacti:
Advantages of MRTG: simple and easy to use. After installation, you only need to change the configuration file.
1. text-based databases cannot be reused;
2. data can only be viewed by day, week, month, or year;
3. Only two DS (one line and one block) can be drawn );
4. data needs to be painted every time data is retrieved, which wastes system resources;
5. No management functions;
Advantages of rrdtool:
1. Data can be reused in rrd storage format. For example, I can add the data in an rrd file to the data in another rrd file.
2. You can define a graph for any time period, that is, you can draw a graph of data from the past six months or a graph of the past half an hour.
3. can draw any DS.
4. CDEF allows you to play with data at will.
1. rrdtool is only used to store data and draw images. It does not have the data collection function integrated in mrtg;
2. The use of command lines is very complex, with many parameters.
3. No management function.
In short, rrdtool is a powerful drawing engine.
Because of its complex commands and unfriendly user experience, I wanted to write a system in php. Fortunately, I found cacti ( six months ago ). I only have one word for this tool: "great !".
Cacti is actually a php program that uses snmpget to collect data and rrdtool to plot data. Its interface is very beautiful, so that you do not need to understand the rrdtool parameters to easily draw beautiful images. Even more valuable, it provides powerful data management and user management functions. A graph belongs to a host, and each host can be attached to a tree structure. In terms of user management, as an open-source software, it can actually specify a "Tree", host ", or even each graph that a user can view, you can also use LDAP for user verification! I can't help admiring the thoughtful consideration of the Author! Cacti also provides its own template function, allowing you to add your own snmp_query and script! It can be said that cacti makes up all the "disadvantages" of rrdtool!
Here are two pictures to help you understand:
Ii. cacti installation steps:
Ensure that the software packages GCC, Perl, gd, libpng, and zlib are available before, so it is best to install them under debian.
Apt-cache show mrtg
Package: mrtg
Priority: extra
Section: net
Installed-Size: 1308

Type 'help; 'or' \ H' for help. Type '\ C' to clear the buffer.

Query OK, 0 rows affected (0.00 sec)
Mysql>; exit
5. Install rrdtool
Http:// /~ Dtool-1.0.50.tar.gz...
Make & make install
Compared with mrtg, rrdtool comes with the gd library, so you do not need to install the gd library first. (However, because the gd library provided by rrdtool does not support Chinese characters, the diagram drawn by rrdtool cannot contain Chinese characters. Otherwise, garbled characters may occur ).
Note: rrdtool1.2 version because no longer comes with external lib Library (such as cgilib, zlib, etc.), so need from the /~ Oetiker/webtools/rrdtool/pub/libs/download these libraries for installation. We recommend that you use version 1.0 for ease of use.
6. Install net-snmp
Snmp is installed on almost all network devices and operating systems by default.
The unix system is installed with net-snmp or ucd-snmp (in fact, both are written by the same group of people ).
If you have not installed snmp, you can download the source code compilation installation on the
I mentioned here that installing the SNMP service does not require installing SNMPD. Actually, Cacti needs to use two net-snmp commands ?? Snmpwalk and snmpget are used to collect data.
You can run snmpwalk and snmpget in the system to check whether the command exists. If yes, you do not need to install it. 7. Install cacti
Note: When writing this document, the maximum cacti version is 0.8.6c, and the current maximum version is 0.8.6f. Since versions earlier than 0.8.6f have the SQL injection vulnerability, please download version 0.8.6f or later for installation.
Cp cacti-0.8.6c.tar.gz/www/htdocs
Tar xzvf cacti-0.8.6c.tar.gz
Music cacti-0.8.6c cacti
Cd cacti
Import table:
/Usr/local/mysql/bin/mysql? U root? Prootroot cactidb
Set the configuration file:
Vi/www/htdocs/cacti/include/config. php
$ Database_type = "mysql ";
$ Database_default = "cactidb ";
$ Database_hostname = "localhost ";
$ Database_username = "cactiuser ";
$ Database_password = "cactipw ";
Check whether the preceding items are correct
Crontab? U cactiuser? E
Add cactiuser

(Do not run the preceding command as the root user; otherwise, run chown again? R cactiuser rra/log /)
8. Page settings:
Http: // IP/cacti
Go to the initial cacti settings page:
Here we need to enter some original information:
Enter some information, such as the location of rrdtool, php, snmpwalk, and snmpget, and use ucd-snmp or net-snmp.
Enter the original user and password: admin/admin-
Change admin user password-"
Click Save
Installation complete!
Now you can enter the Cacti world in the browser!
