I'm having the same problems with GWOS 5.3 and Cacti 0.8.7d. Everything is setup correctly, however, there are no graphs. If I run the command to create the graph, I see the graph but no data is visible.

I turned the Cacti poller logging on to the DEVEL level, and when I run the poller manually, I get this:


It keeps on going until I hit ctrl+c. It seems like something is hard coded to use the default paths for php and rrdtool.

cacti -> console -> settings -> paths

I have all of the paths set correctly for GWOS 5.3 in Cacti.

Update: I added symbolic links for those paths... now the poller is running fine, but still no graphs.

I have exactly the same problem

For those that are having an issue with the PHP requiring, what I did is the following:

- Downloaded the latest and greatest Cacti package.
- Followed the installation guide that "skau2" provided.
- Edit the following file: '/usr/local/groundwork/apache2/htdocs/cacti/install/index.php'
- Edit the following line: " $extensions = array("session", "sockets", "mysql", "xml");" by removing "sockets".
- Continue with the installation.

So far, it works OK. Let me know if this helps.

After re-installing cacti and removing sockets as above, I now seem to have it graphing correctly. I also had to create sym links for the PHP,PERL and RRDTOOL binaries as it was defaulting to the wrong location for these files for some reason even though I had set the paths in the install - pointing to the groundwork binaries.

Hmm, I didn't need to do any of that as I just pointed the files Cacti required to the ones GWOS MCE provided. In any event, I'm glad it worked out for you.

I have been able to add Cacti to Groundwork and it is creating graphs. But polling the same server twice, for groundwork and for Cacti to create graph, doesn't make sense to me. Is there anyway to get Cacti display Groundwork generated graphs under /groundwork/rrd?

Yes, there is. The short version is: You need to setup a blank data input method in cacti. I call my "PolledNagios" so I know where the data is coming from. Create/modify your data template to match the nagios data. Then create your data sources with your data input method from above, making sure to mark them as disabled, so cacti won't try to include them in the poller.

It's a little tricky initially to make it work, since you have to create everything manually the first time. Once you get it going though, it's easy to create others with just a couple steps.

Dave99,

Thank you for your reply. Here is what I did from your explaination but haven't been able to display any graph. Can you please shed some light on it and point out any mistake I made. Thank you in advance.

01. Create Data Input Method
Name: PolledNagios
Input Type: Script/Command
Input String: <Blank>
Input Fields: None
Output Fields: None

02. Create Data Template
Name: PolledNagios
<Datasource>
Name: (Use Per-Data source Value (Ignore this Value))
Data Input Method: PolledNagios
Associated RRA's: Daily, Weekly, Monthly, and Yearly
Step: (Use Per-Data source Value (Ignore this Value))
Data Source Archive: (Use Per-Data source Value (Ignore this Value))
<Data Source Item>
Internal Data Soruce Name: (Use Per-Data source Value (Ignore this Value))
Minimum Value: (Use Per-Data source Value (Ignore this Value))
Maximum Value: (Use Per-Data source Value (Ignore this Value))
Data Source Type: (Use Per-Data source Value (Ignore this Value))
Heartbeat: (Use Per-Data source Value (Ignore this Value))
Output Field: (Use Per-Data source Value (Ignore this Value))
Custom Data: <Blank>

03. Create Data Source
Select Data Template: PolledNagios
Host: WindowsHost (a machine that is being monitored by GW and graphs are available under groundwork/rrd folder)
<Supplement Data Template Data>
Name: Generic_CPU_Load
Data Source Path: /usr/local/groundwork/rrd/WindowsHost_Generic-check_nt_cpuload.rrd
Step: 300
Data Source Active: Yes
Internal Data Source Name: Generic CPU Load
Maximum Value: 0
Minimum Value: 0
Data Source Type: Gauge
Heartbeat 600
Output Field: <Empty>

i have correctly integrated cacti in GW and configured it following this post.
By the while i can't get graph and turning on the debug mode in cacti i get this error:

RRDTool Says:

ERROR: No DS called 'wmi_cpu' in '/usr/local/groundwork/rrd/itsrv-case_wmi_cpu.rrd'


I've understood that the problem is the string "wmi_cpu", I tried different string just to be sure and as expected I got the same error.
I can't understand which string must be set in "Internal Data Source Name" field in "Data Sources" configuration. Leaving the field free i get an error from cacti that ask me to write something. Writing a string with spaces also generate an error.

Using GW performance tool i can plot all the rrd files in /usr/local/groundwork/rrd folder. It works perfectly.

Thanks in advance
Paolo

Hi Paolo i jsut ran into this issue to and this is what i needed to do to make it work.

In performance configuration you will have the RRD Create command something like this:

$RRDTOOL$ create $RRDNAME$ --step 300 --start n-1yr DS:HDD:GAUGE:1800:U:U RRA:AVERAGE:0.5:1:8640 RRA:AVERAGE:0.5:12:9480

The DS name that you need to provide to Cacti is the bolded value that's what i did and it stopped giving me the error.

Now i don't have it yet fully functional, Cacti tries to display the graph but all it gets is a picture as in the attached jpeg.

Hi Paolo, try running "rrdtool info" on the rrd file to get the names of the datasources it contains. I use the rrd's that are created by PNP and the data source names are numbers.

I'm having trouble with my integration of Cacti with Groundwork - well actually just install of Cacti, but the kind folks on the Cacti forum told me to ask here (http://forums.cacti.net/post-173763.html), so here I go:

I installed cacti according to the info above. I haven't added any hosts yet - I only have the default localhost checks running. These aren't generating any lines on the graphs - all the counters show up as NaN. When I look at debug output in the logs I see messages like:



and



However, when I run the cacti scripts directly from command line I get results returned fine.

Someone on the Cacti forum suggested that snmp wasn't turned on, however I can snmpwalk localhost successfully. Perhaps they meant that the SNMP extension for PHP isn't there - although looking at the config string from phpinfo() it looks to be compiled in by the presence of "--with-snmp=/usr/local/groundwork/common".

Anyone got any ideas about what might be going wrong here?
