Cacti Configuring traffic summarization

Cacti is a very good flow monitoring software, using rrdtool mapping, can accurately and systematically display the flow chart. There is a need to summarize the inbound and outbound traffic for all servers on the line and export the updated data every 5 minutes.

First, cacti precision setting

1, modify the RRDtool storage size

Console-management->data Sources->rras

Modify template parameters, such as hourly (1 minute average)

Consolidation functions set to: Max, Min, average, and last

X-files factor modified to: 0.5

Steps set to: 1 ( draw once every 1 minutes )

Rows is set to: (The number of data records saved in the TimeSpan period is minutes)

TimeSpan set to: 3600 ( time span )

The recommended template parameters are as follows:

Hourly (1minute Average	Daily (5minute Average	Weekly (5minute Average	Monly (5minute Average	Yearly (1hour Average
1	5	5	5	60
60	288	2016	8928	8760
3600	86400	604800	2678400	33053184

2. Modify the Data index

Console-management->templates->data Templates

(1) Add the 5 rrd templates just created in associated RRA ' s
(2. Set Step to 60 (draw once every 60 seconds)
(3, set the heartbeat to 120 (120 is the time-out)

3. Modify Crontab Task

*/5 * * * */usr/bin/php/var/www/cacti/poller.php >/dev/null 2>&1

Revision changed to

*/1 * * * */usr/bin/php/var/www/cacti/poller.php >/dev/null 2>&1

4, rows default storage data Maximum value is 10000, to store more than 10000 rows of data, you need to modify the parameters in the lib/rrd.php file MaxRows

Refer to the following:

/* Basic Export options */
$xport _opts =
"--start= $xport _start". Rrd_nl.
"--end= $xport _end". Rrd_nl.
"--maxrows=100000". RRD_NL;
$xport _defs = "";

Second, the use of plug-in aggregate combined traffic summary

can also be manually added, reference blog: http://lihuipeng.blog.51cto.com/3064864/638895, but I do it is problematic, inbound and outbound data, no time for fine-tuning.

1, install the plug-in

View official documents, Http://docs.cacti.net/plugin:aggregate, download and unzip to plugin, then on the page Console-configuration-->plugin Management can be installed.

2. How to use

console-management->graph Management, select the monitoring host you want to add to the rollup
