Cacti monitors Redis implementation process and cacti monitors redis
Cacti is a set of graphic analysis tools for network traffic monitoring developed based on PHP, MySQL, SNMP, and RRDTool. It is widely used in server O & M monitoring. Cacti provides plug-in management. As long as you write a specific template as required, you can monitor the traffic of any service. This article will introduce two templates: the Cacti templates for MongoDB and Redis. You can use them to monitor the traffic of your MongoDB and Redis services.
1. Upgrade python. If it is the default python version of the system, the following error will occur:
Python setup. py install
Traceback (most recent call last ):
File "setup. py", line 3, in?
From redis import _ version __
File "/usr/local/src/redis-2.4.11/redis/_ init _. py", line 1, in?
From redis. client import Redis, StrictRedis
File "/usr/local/src/redis-2.4.11/redis/client. py", line 240
With self. pipeline (True, shard_hint) as pipe:
^
SyntaxError: invalid syntax
2. Install python. First configure the python environment and download the python source code.
Wget http://www.python.org/ftp/python/2.5.2/Python-2.5.2.tar.bz2
$ Tar-jxvf Python-2.5.2.tar.bz2
$ Cd Python-2.5.2
$./Configure
$ Make
$ Make install
[Root @ mysqlvm2 Python-2.5.2] # python
Python 2.4.3 (#1, Jun 11 2009, 14:09:37)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-44)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>>
Version is still 2.4.3. The solution is as follows:
# Cd/usr/bin
# Ll | grep python // view python in this directory
# Rm-rf python
Just repeat the soft connection.
[Root @ mysqlvm2 Python-2.5.2] # ln-s/usr/local/bin/python/usr/bin/python

3. Download The apsaradb for redis template.
Wget http://mysql-cacti-templates.googlecode.com/files/better-cacti-templates-1.1.8.tar.gz
Configure monitoring script
To monitor mongodb or redis, You need to download better-cacti-templates-1.1.8 \ scripts
The ss_get_by_ssh.php script must be placed on the cacti server.
If cacti is installed in the/var/www/html/cacti/directory.
Put the file under the scripts directory. Don't forget to check the permissions. You must have the execution permission.
Then modify the file. Modify the options in about 40 rows.
#===================================================== ============================================
$ Ssh_user = 'root'; # SSH username
$ Ssh_port = 22; # SSH port
$ Ssh_iden = '-I/root/. ssh/id_rsa'; # SSH identity
# Modify the location of your ssh connection user and authentication private key based on your configuration.
If the value is greater than 50 rows, you can also modify the default port to be tested (if redis is not a normal default port, You need to modify the value ).
$ Redis_port = 6379; # Which port redis listens on
4. Import the template. The template directory is better-cacti-templates-1.1.8 \ templates.
On the cacti interface, create the Graph of the redis server as follows:
5. View Graph as follows:

Cacti monitoring
1. Enable the snmp service for vswitches and vrouters
2. Specify an snmp data receiving server for the vswitch and vro
3. You can monitor the data After configuring the preceding two items.
At the same time, we recommend cacti, the best software for network monitoring I have found.
Red hat linux unless you pay for a red update source...
No, you have to at least compile and install the software to solve the dependency problem.

Nagios is recommended for server monitoring, which is very powerful.
Installing the cacti monitored host is always in the Unknown state;
# Mysql-u root-p
Password:
# Mysql> create database cacti;
# Mysql> grant all on cacti. * to cacti @ localhost identified by 'cacti ';
Modify cacti to make it accessible to the database
# Vim/usr/local/cacti/include/config. php
# $ Database_type = "mysql ";
# $ Database_default = "cacti ";
# $ Database_hostname = "localhost ";
# $ Database_username = "cacti ";
# $ Database_password = "cacti ";
# $ Database_port = "3306 ";
Import database files
# Mysql-u root-p cacti <cacti. SQL
