Have measures every five seconds

[mattdu61]

Hello!
Firstly, I'm french so my english isn't very good. Please excuse me.

I have a project to do:

I must have measurement of network equipment with SNMP. This works, but every minutes. I want to have new values every five seconds and record them in a XML file.

Can you help me? Because I am a little lost right now with all the settings...

Thanks.

AFAIK Cacti and *nix CRON can handle events with minimum of 1 minute interval.

Well, for Cron I bypassed the problem. Here is what I did:

Code: Select all

crontab -e

Then I wrote this line:

Code: Select all

*/1 * * * * /home/matthieu/poller.sh

My script, poller.sh:

Code: Select all

#!/bin/sh

nohup php /var/www/cacti/poller.php --force > /dev/null 2>&1 &
sleep 5
nohup php /var/www/cacti/poller.php --force > /dev/null 2>&1 &
sleep 5
nohup php /var/www/cacti/poller.php --force > /dev/null 2>&1 &
sleep 5
nohup php /var/www/cacti/poller.php --force > /dev/null 2>&1 &
sleep 5
nohup php /var/www/cacti/poller.php --force > /dev/null 2>&1 &
sleep 5
nohup php /var/www/cacti/poller.php --force > /dev/null 2>&1 &
sleep 5
nohup php /var/www/cacti/poller.php --force > /dev/null 2>&1 &
sleep 5
nohup php /var/www/cacti/poller.php --force > /dev/null 2>&1 &
sleep 5
nohup php /var/www/cacti/poller.php --force > /dev/null 2>&1 &
sleep 5
nohup php /var/www/cacti/poller.php --force > /dev/null 2>&1 &
sleep 5
nohup php /var/www/cacti/poller.php --force > /dev/null 2>&1 &
sleep 5
exec php /var/www/cacti/poller.php --force > /dev/null 2>&1

And this is a part of my log file (/var/www/cacti/log/cacti.log):

Code: Select all

Poller runs every five seconds(approximatively), but I can't see those measures on my XML files. ( I create them with rrdtool dump...)

Does anyone have an idea?
Thanks.

AFAIK rrdtool minimum granularity is 1 minute.
