Cacti

The poller uses perlscripts to process inputdata. I had the problem that some of these perscripts hung for no reason. (ok, there must be a reason, but it works by 99,99% of all polling-intervals and then just fails.. real Vodoo!! ) I decided to implement a "maximum runtime" to this scripts...

tmoore, can you please specify the meaning of "First Quarter 2006" ?? ;) Shall i upgrade my environment (+3700rrd's ) to 0.8.6h ? A clear "roadmap" (sorry, MS-Slang) would be a big fortune.. BTW: it's not that easy to upgrade such an environment without loosing polling data.. (co...

that depends on your distribution... mandrake uses AFAIK RPM-Packages... => so you have to install xml-packages... perhaps you have to reinstall the php-packages after the xml-stuff to ensure that it detects the xml-library the packages are named libxml or similar.. perhaps a mandrake-specialist is ...

you can use grep to filter out what you're intrested in... $ grep -i error /tmp/cactid.out => prints out all lines which contain the word "error" (case-insensitive) of course, you can put a grep directly into crontab... but I think it makes more sense if you grep through a "offline&qu...

search the forum wth the keywords "bonsai" and "Cactistoric"

I'm not exacly sure how they work... but AFAIK the data gets more and more "unsharp" for older data..
(it stores the averages of the data... not the data themself..)

hmm... have you tried creating datasources, that contain the same DS-Names as your rrd-files... then replace the existing rrd-files with your files... you can use rrdtool info $filename.rrd to gain infos about your rrd-files.. (max. value, type, heartbeat, ds-names etc..) => this worked for my while...

hmm.. does your php have xml-support built-in ? you can check this with the phpinfo() function: create a file on your webserver that simply contains <? phpinfo(); ?> and name iit phpinfo.php (or similar... but must have the ending .php) then point your browser to that file.. http://$yourserver/$some...

hmm... interesting question...

doesn't cacti means the same as cactuses
the plural of cactus ?

hmmm... have a look at the logo..

hmm... your php.ini (usually located in /etc/ or /etc/php or similar) has the line memory_limit = 8M ; Maximum amount of memory a script may consume (8MB) => increase that value (for example to 32M for 32megabytes.. ) This value indicates the maximum memory a PHP-Script can use... regards, mänu

use the command "whereis" to find out where the binary of rrdtool is located..

baboo@zeus baboo $ whereis rrdtool
rrdtool: /usr/bin/rrdtool

=> the symlink also works, but is not really elegant..

with perl/php you have the ability to
1. use internal snmp-functions or
2. to start snmpwalk/get and parse the output
if you want to get snmp-data..

Which solution is better/faster/uses less memory?

did anyone some benchmarks? experience?

hmm... is the leading slash really missing?

does this only occur with diskspace-graphs?

doesn't clearing the pollercache solve the problem?

regards, mänu

looks like your cacti doesn't find your rrdtool...

change the rrdtool-path to /usr/bin/rrdtool

=> the leading slash is important..

hmm... cacti only collects and displays statistically data.. this part will work.. => you have to use other tools for the traffic creation.... perhaps some of the Guru's know a tool.. (cat /dev/urandom |nc your_boss'_pc 445) I'm able to get the traffic per qos-group from my 3com switches... it's wor...

with cacti, you can to your latency measurings, traffic, dns-server usage/capacity... you can also write your own scripts (you need to in some cases..) (for windows, use vbscript,jscript (WSH) or perl - of course batch-files will also work.. but they're borin) The adaption of Unix-Scripts is usually...
