Cacti monitors redis implementation process

Cacti It's a set of bases PHP,MySQL,SNMP And RRDTool A graphic analysis tool for network traffic monitoring . It is widely used for The server In operation and maintenance monitoring ,Cacti Provides a plug-in management , Just write a specific template as required , Then you can monitor the traffic of any service . This article is to introduce two templates , Namely MongoDB and Redis Of Cacti Templates , Use it , You can treat your MongoDB and Redis Service traffic monitoring .

1, upgrade Python, At this time, if it is the system default python edition , The following errors 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 python Environmental Science , download 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

[[email protected] Python-2.5.2]# python

Python 2.4.3 (#1, Jun 11 2009, 14:09:37)

>>>

Version still 2.4.3 Of , The solution is as follows ：

#cd /usr/bin

#ll |grep python  // Look in the directory python

#rm -rf python

Just make a soft connection again

[[email protected] Python-2.5.2]# ln -s /usr/local/bin/python /usr/bin/python

3, Then download redis The template of

wget http://mysql-cacti-templates.googlecode.com/files/better-cacti-templates-1.1.8.tar.gz

Configure monitoring script

mongodb or redis What you need to monitor is what you download in the directory better-cacti-templates-1.1.8\scripts Under the

ss_get_by_ssh.php This script This script needs to be placed in cacti The service side .

If you cacti It's loading /var/www/html/cacti/ Under the table of contents .

Put the file under it scripts Under the table of contents . Don't forget to look at permissions . Have the right to execute .

Then modify the file . Mainly modify the options , In about 40 That's ok .

# ============================================================================

$ssh_user  = 'root';                          # SSH username

$ssh_port  = 22;                              # SSH port

$ssh_iden  = '-i /root/.ssh/id_rsa';  # SSH identity

## Modify according to your configuration , Yours ssh Connect the user , And the location of the authentication private key .

It's time to 50 That's ok , You can also modify its default port to detect （ If redis It is not the normal default port startup. You need to modify these ）.

$redis_port    = 6379;                    # Which port redis listens on

4, Import template , Template directory is better-cacti-templates-1.1.8\templates

stay cacti Interface import interface , establish redis The server Of Graph, As shown below ：

5, To view the Graph design sketch , As shown below ：
