TheWitness, I'm using a handmade MS-Excel solution ;) 1. write the output of `sar`to a file sar -u 3 9999999 > io_output 2. import that file in Microsoft Excel with 'spaces' as column-delimiters 3. add the polling times manually 4. create a graph.. As you see it's a pretty semi-automatic process, bu...

I/O Stats with and without 'Boost Plugin'

Hi there, I just wanted to show you some I/O statistics from our test-cacti machine. We had a big I/O issue without the 'Boost Plugin', so that one polling cycle couldn't finish before the next one started. After using the Boost Plugin we are now able to reduce the I/O massively! Thanks a lot for th...

SOLVED: cacti 0.8.7b / PA 2.0 / Boost Plugin 1.7 SVN / spine

Hi there, I installed the newest version of cacti ( 0.8.7b ) with PA 2.0 and the latest ( 18.03.08 ) SVN checkout of the Boost Plugin . To make things easy I'm just graphing the 'localhost' with the default config (load, usercount, ...) In my first test I'm not going to use the "Boost Plugin". All I...

I disabled the line with the truncate on the table poller_output in the script to see what datasources are causing the problem. Maybe the logfile in debug mode will show me what exactly goes wrong.

Ok, so it does actually the same as the script "poller_reindex_hosts.php", that can be executed on the shell 'by hand' ?
Thanks..

Reinhard, thanks for you reply. Now I know what recaching means :lol: Do you see any connection between the drop of my recache time and my polling time? Am I right that the recaching time souldn't be a constant value as shown in my graph above ? If I got you right, this value should change all the t...

What is a "recache event" ?

Hi there, does anybody know what a 'recache event' is ? I see a sudden drop of my 'recache time' and a drop from 12 to 0 hosts that are beeing recached. At the same time there is also a drop of the poller runtime. For me it looks like those 'recache events' are something bad :o Does anybody know whe...

I guess it's the best way to actually simulate a cacti installation. You can download the perlscript at his site ( http://o...
