Adding Cacti to Groundwork.
Cacti is a handy trend & performance history graphing app. Here are some instructions on how to integrate it with the groundwork system. For simplicity sake, I've opted not to use the single sign on (SSO) option on my system, as it's not really worth the effort. I did play around with it and include instructions on using SSO, it seems to work, but I'm not 100% sure it works right. (At least on my test VM, doesn't seem to destory the session upon logout of groundwork). Just skip the SSO stuff if you don't want to use it, the rest of the process doesn't change.


1) Download Cacti

###

2) Create the MySQL database:

# Import the default cacti database:

# Optional: Create a MySQL username and password for Cacti. If you've added a mysql passwd, you'll need to login with that.

###

3) Edit Cacti Config in /usr/local/groundwork/apache2/htdocs/cacti/include/config.php and specify the MySQL user, password and database for your Cacti configuration.

###

4) Add the cacti poller to your /etc/crontab file (I run the poller as root, due to some of the scripts I use in cacti):

###

5) Add cacti directory to the /usr/local/groundwork/apache2/conf/httpd.conf file for SSO

# Restart Apache

###

6) Go to cacti admin site:

# Modify Paths:

# Edit Cacti Config (part 2)
#Settings -> General Tab:

#Settings -> Paths:

#Add fonts path:

#Settings -> Visual (you can play with the fonts & sizes, these are what I use, just because it's the included font in rrdtool)

#Settings -> Authentication (since we are using SSO. If you don't want SSO, leave this checked.)

###

7) Wrappit
#General Tab:

#Menu: (no sub menu's needed)

#SSO

#Export

###

8) Add view to admin
# Administration -> Roles -> Administrators

# Cacti should be one of the options in the drop-down menu now.

END.

Notes: The PHP that's included in groundwork does not have the '--enable-sockets' option compiled in. This might mean that a few of the scripts available in cacti don't work quite right. I didn't seem to notice any problems when I used it initially for a few weeks, however I've recompiled PHP to add that support on my system now. I'll try to add instructions on that down the road. It's also possible to display RRD's that are generated by Nagios in Cacti (to avoid duplicating the same type checks that Nagios already performs, such as CPU load, disk space etc). I'll document that later also.

Thanks for the detailed instructions, they're great! One _slight_ enhancement: to make the Cacti part easier there are Cacti RPMs downloadable from:

Nice posting.

I was curious if it's possible to integrate the graphs generated by cacti in to the status page for Groundwork?

I wonder the same as Scott (routehero)... to integrate the graphs to the status page would be sweet

/MrNilsson

I have followed the instructions, but it doenst work for me:(

When i doe http://<server>/cacti/install

I don't get the installation page i just go to the standaard welcome page of Groundwork..

Anybody an idea?


Thnx!

If you log into groundwork, then manually go to the cacti install page, does it work then?

nopz doesnt work for me
any ideas?

If it is taking you back to the login page, then it sounds like the session isn't being set right.

Look at /usr/local/groundwork/guava/packages/cacti/views/cacti.inc.php and make sure you have a line that looks like:


and make sure your httpd.conf has correct authentication set as listed above.

Hi,
I'm Having exactly this same problem.
I've went through all steps as above and stuck on login to cacti. When I'm opening http://my_ip_address/cacti/install it's redirecting me to main gw login page (http://my_ip_address/monitor/index.php).
When I was looking into /usr/local/groundwork/packages there was no cacti folder so I've created one and added
to /usr/local/groundwork/packages/cacti/view/cacti.int.php

Am I missing something else in GW (like some extra packages for suport Cacti) ?

Apache error log (from /usr/local/groundwork/apache2/logs/error_log) looks as follows:


I've been searching for that problem on forum, but given solution (stop apache, rm session* and tpl* files, restart apache) didn't help at all.

Do you have any suggestions ?

Thanks

UPDATE:

Problem solved
Iv'e removed /usr/local/groundwork/guava/packages/cacti,
add cacti again in wrappit and open cacti from GW.

I am having the same problem attempting this integration. Using the latest versions of both products (Groundworks Monitor and Cacti). I get through step 6 and run into the following:
Warning: session_destroy() [function.session-destroy]: Trying to destroy uninitialized session in /usr/local/groundwork/guava/includes/sessions.inc.php on line 126

I tried the steps suggested in this thread to add Cacti using Wrappit. No success there as well.

Any help or suggestions out there?

Running on CentOS 4.4 server.

TIA

Help!!!
I have being trying to add cacti to groundwork to no avail using the instructions in this thread.
I am running redhat enterprise linux 5 with groundwork community edition 5.2.1.
I enable single sign on on apache.
When I log on to add cacti with wrappit, cacti installation runs endless.
I have to manually stop it.
Cacti is added to the list of packages, added in roles, but does not appear in drop down menu.Cacti shows uninstalled from the package list.
Any attempt to install from the package list fails
Help is neeed on how to install Cacti successful in guava.
Thanks in anticipation

It seems that guava can be kind of finicky sometimes about making the whole wrappit thing work. I'd remove the current entry for the cacti wrap, and try re-adding it.

At last I am able to get Cacti inside the groundwork interface but the page cannot open yet.
I used the following in my apache config file

Alias /cacti/ "/usr/local/groundwork/apache2/htdocs/cacti/"

<Directory "/usr/local/groundwork/apache2/htdocscacti">
Options Indexes
AllowOverride None
Order allow,deny
Allow from all
</Directory>

PLEASE help , I don't know what I may be missing

I created the files package.pkg and cacti.inc.php, installed cacti from package list under administration menu. Added cacti to roles. Cacti appears on the menu but a click on it gives the following error message

AN ERROR HAS OCCURED THE ATTEMTED RESPONSE IS BELOW

First thing is you are missing a / in this between htdocs & cacti:


Second thing is I would try to get cacti up & working & configured correctly before you start trying to add it into the menu with wrappit. Not sure if you are there yet.
