As long as you freeze changes, you should be able to do the following:

mysqldump -u root -p cacti > /backupdir/cacti_back.sql

then for the Cacti environment, something like:

tar -cf /backupdir/cacti_web.tar <web_root>/cacti

If you are upgrading the box, it is likely that you will miss a few polling cycles.

Also, please note that for some reason, freebsd has never faired too well in the performance benchmarks for some reason. I suspect memory mapped IO with rrdtool is broken or something.

Not only did we get roughly 8x the poll speed, but check out the CPU usage of our Cacti server! Can you tell when the switchover occurred?

It's fair to say that cactid has given our stats server a new lease of life.

FreeBSD performance seems pretty good to me...

Pentium 4 2.8Ghz; 2GB RAM
FreeBSD 6.0-RELEASE
PHP 4.4.2
MySQL 4.1.18
RRDTool 1.2.12
cacti 0.8.6h
cactid 0.8.6g

I am VERY impressed with Cactid performance, are there specific steps for migrating to it? Version requirements?

We're running h with the plugin architecture on Suse 10.

No. Simply use the latest stable release. Perhaps you will prefer compiling it on your own (may net some ...-devel packages on linux). But pay attention to the hints for the last release. It requires full path for all binaries used in Data Input Methods and ./resource/script_queries/* scripts

One quick question in regards to the script change: do you mean that for each script/command listed on the "Data Input Methods" page I need to add the full path for perl (i.e. /usr/bin/perl) or php to the "Input String" field?

Post by **gandalf** » Tue Mar 28, 2006 1:42 pm

Yep. If you prefer, you may do so using some SQL magic (or, as in my case, phpmyadmin). But don't forget to check the scripts in resource/script_queries.

Finally I'm going to guess that if I run into:

Code: Select all

|path_php_binary|

I simply replace it with:

Code: Select all

/usr/bin/php5

<and so I don't look/sound so stupid, I'm being specific for the next guy who comes along

And to find an occurance of perl or php that needs to be fixed, would you say the following is the easiest:

Code: Select all

cat * | grep perl

?

Try these commands to locate items:

which perl
whereis perl

and as a last resort"
find / | grep "filenamehere"

I use locate (and updatedb) for finding files, if "which" doesn't work.

The commands I offered were to find files calling perl, like:

Code: Select all

cat /usr/cacti/resource/script_queries/* | grep perl

would provide me with every line using "perl" - which would be:

Code: Select all

        <script_path>/usr/bin/perl |path_cacti|/scripts/cbwfq.pl</script_path>
        <script_path>/usr/bin/perl |path_cacti|/scripts/query_unix_partitions.pl</script_path>

Which tells me I would need to edit both of those scripts (except that I already have and the full path is there).

How do you gather these stats?

Not using cactid I'm seeing the same graphs for my machines CPU useage... who wants to hold my hand through the move to cactid so I can get it to work?!

I know there's a plugin for it, try searching the forums for "pollperf" - hope that helps.

In reference to several previous posts....

"updatedb" is a command that indexes the filesystem and stores the names of all the files in a database

"locate" searches that database for a given name

The easiest way to search for text in files is with grep. Using "cat * | grep <pattern>" will simply return a bunch of lines - you won't know what file they came from, or where in the file they exist. If you use "grep -rHn * <pattern>" you will get a recursive search, that will print the name of the file, the linenumber, and the line in the file where <pattern> occurs. Much easier.

Amen - thanks!

oops, think it should be: grep -rHn <pattern> *
