[quote="gandalf"] Wenn ein Skript dabei ist, bitte nicht vergessen dieses in das ./scripts Verzeichnis zu kopieren

in welches Scipt verzeichnis? script_server oder script_queries???

in which script folder? script_server or script_queries???

Danke /Thanks
Pat

The script folder exists only once, directly under cacti default folder. e.g. for RHEL /var/www/html/cact/scripts.
The other folders are at /var/www/html/cacti/resources/... and are not related (at least if your're not using a Data Query or a php script server script). In any case, the author should have included words on what to put where.

We have this folders:

drwxr-xr-x 2 cacti cacti 144 2007-01-18 01:23 script_queries/
drwxr-xr-x 2 cacti cacti 112 2007-01-18 01:23 script_server/
drwxr-xr-x 2 cacti cacti 280 2007-05-22 18:31 snmp_queries/

Aren't this the default folders?

The "default folder" is the one where e.g. poller.php lives in

Hi @all,

I found this topic and I´ve a few questions, because no graph will be displayed:

Here´re my steps:
I only imported the xml-File named "cacti_graph_template_combined_used_disk_space_test.xml" via console -> Import Templates ... without any errors.

Then I went to "Devices" and create a graph for the device I want to monitor.
Next he wanted to know "Index Type, Index Value and Output Type ID" ???

I entered nothing (is this right?) and switch to Graphs to have a look at my newly created graph, but nothing will be displayed.

Where´s my mistake, and where I can enter the partitions I want to monitor?

Please can anyone tell me a detailed install- and configureguide for this?
Thanks in advance.
Greets from Germany,
Michael

How to use

1) Download and install this
- http://docs.cacti.net/usertemplate:data:host_mib:disk_usage

2) Create graphs with that data query ("SNMP - hrStorageTable")

Sample:


3) Import mokeybrains' combined graph template, then combine existing graphs
- http://forums.cacti.net/viewtopic.php?p=99678#p99678

Import the XML file.
Click on
*Console
*Graph Management
*Add (upper right of screen)
*Pick Combined - Used Disk Space - 5 partitions
*Pick a host
*Click Create
*fill out all the partitions

Sample:

[Michael66]

... I´m going mad …

I followed your steps:
First I downloaded Disk Space Usage from
http://docs.cacti.net/usertemplate:data ... disk_usage

then I followed steps 1-4 as described (untar, drop into snmp_queries, import xml via Import Feature and add to a device)
so long ... no error

Code: Select all

Cacti has imported the following items:
CDEF
[success] Host MIB - hrStorageTable Units [update]
GPRINT Preset
[success] Normal [update]
Data Input Method
[success] Get SNMP Data (Indexed) [update]
Data Template
[success] Host MIB - hrStorageTable [update]
Graph Template
[success] Host MIB - hrStorageTable [new]
Data Query
[success] SNMP - hrStorageTable [new]

after the import I took a look at
-> Data Template and found "Host MIB - hrStorageTable"
-> Graph Template ... found "Host MIB - hrStorageTable"
-> Data Query ... found "SNMP - hrStorageTable"
-> Data Input Methods but found no "Get SNMP Data"

And when I want to create the graph, I only got error
This data query returned 0 rows, perhaps there was a problem executing this query.
I ran it in debug mode and the output was:

+ Running data query [12].
+ Found type = '3' [snmp query].
+ Found data query XML file at '/srv/www/htdocs/cacti/resource/snmp_queries/hrStorageTable.xml'
+ XML file parsed ok.
+ Executing SNMP walk for list of indexes @ '.1.3.6.1.2.1.25.2.3.1.1'
+ No SNMP data returned
+ Found data query XML file at '/srv/www/htdocs/cacti/resource/snmp_queries/hrStorageTable.xml'
+ Found data query XML file at '/srv/www/htdocs/cacti/resource/snmp_queries/hrStorageTable.xml'
+ Found data query XML file at '/srv/www/htdocs/cacti/resource/snmp_queries/hrStorageTable.xml'

Whats wrong here, why he said, that no SNMP Data returned??
When I run for example at the console:
snmpwalk -Os -c public -v 2c localhost system
then I get a result.

Perhaps you´ve an idea again?
If you need further information, please let me know.
Kind regards,
Michael

>> -> Data Input Methods but found no "Get SNMP Data"

It's no need to care.

And when I want to create the graph, I only got error
This data query returned 0 rows, perhaps there was a problem executing this query.
I ran it in debug mode and the output was:

...
+ Executing SNMP walk for list of indexes @ '.1.3.6.1.2.1.25.2.3.1.1'

...

Whats wrong here, why he said, that no SNMP Data returned??

snmpwalk -Os -c public -v 2c localhost system
then I get a result.

Try snmpwalk to ".1.3.6.1.2.1.25.2.3.1.1" (or upper OID: ".1.3.6.1.2.1.25.2.3.1") instead of "system".
If SNMP agent on your target host doesn't support HOST-RESOURCES-MIB::hrStorageTable, you can't use this template.

[Michael66]

so when I try
snmpwalk -Os -c public -v 2c localhost .1.3.6.1.2.1.25.2.3.1
then I get answer

Please can you say again something to how I have to create the graphs with that Data Query?
Thanks in advance.

Hmm, that result looks like fine..

Is there something to prevent poller user from accessing these SNMP OIDs?
e.g.) Did you restrict access rights to particular user in your snmpd.conf?

For example, if your poller is "cactiuser", please check like this:

# su - cactiuser -c '/path/to/snmpwalk -v1 -c public localhost .1.3.6.1.2.1.25.2.3.1'

[Michael66]

... I get the same answer as I do it with root-user ...

I think there´s something wrong with the graphs, thats why I asked about how to create the graphs ...

[noname]

But your Cacti can't get information properly..
Other graphs using SNMP query (e.g. "SNMP - Interface Statistics") are working for localhost?

I have tried to import the mokeybrains xml, but i have strange values reported in the related graph.
As you can see from the screenshot provided, i have 2 Gbit used on / partition (3 Gbit is the total space), but in the combined graph i can read under the Capacity: "712.94 k".
How i can solve this issue ? And if i want to combine more than 5 partition ? How i can do it ? (it's a stupid question i know...)
Thanks to all for your precious support.

Please anyone can help me ?

Ah, indeed.
"HOST-RESOURCES-MIB::hrStorageTable" returns its disk size (used and total) in "blocks",
so actual size should be calculated by multiplying blocksize.

gandalf's 'disk_usage' template fulfills it by using CDEF "Host MIB - hrStorageTable Units".

Code: Select all

cdef=CURRENT_DATA_SOURCE,|query_hrStorageAllocationUnits|,*

Try this graph template:

cacti_graph_template_combined_used_disk_space_blocksize.zip

After imported, simply change graph template of existing graph. (or create new graph by the same way as original)

Comparison between original and this one
