For the image "graph_image.php.png"
Please click on it and select one of the wrenches to see the full "rrdtool graph" statement and post this.
For the Data Template issues: Please remember, that NONE of the changes of a Data Template will have effect for already created rrds. And the DEBUG shows only the create statements, cacti will use when generating a new rrd. If you want to know how the ACTUAL rrd is defined, you will have to use "rrdtool info" instead.

These numbers are way wrong:
| Code: |
CACTID: Host[1] DS[178] SNMP: v2: red.paulbeard.org, dsname: Load_15min, oid: .1.3.6.1.4.1.2021.13.15.1.1.3.1, value: 3811363840

First of the OIDs are wrong. As you can see, they don't change even though the data source changes. No sure what's up with that.
The OID for Load_15min is .1.3.6.1.4.1.2021.13.15.1.1.11.x where x is the index value of the spindle. And that's what the xml file has, as well.
| Code: | <diskIOLA1>
<name>Load Average (1 min)</name>
<method>walk</method>
<source>value</source>
<direction>output</direction>
<oid>.1.3.6.1.4.1.2021.13.15.1.1.9</oid>
</diskIOLA1>
<diskIOLA5>
<name>Load Average (5 min)</name>
<method>walk</method>
<source>value</source>
<direction>output</direction>
<oid>.1.3.6.1.4.1.2021.13.15.1.1.10</oid>
</diskIOLA5>
<diskIOLA15>
<name>Load Average (15 min)</name>
<method>walk</method>
<source>value</source>
<direction>output</direction>
<oid>.1.3.6.1.4.1.2021.13.15.1.1.11</oid>
</diskIOLA15>

I suppose I can re-import the xml file. is there something else I should be looking into? |

Please remember to reload the poller cache (there's a nice script out there) or use Clear Poller Cache which in fact reloads the poller cache. You may have a look at the cache to verify, that current XML OIDs are used

Finally, I got this to work. alas, some of the data isn't useful (the reads/writes are evidently since boot time, so it's just a slope: I was hoping for transactions per second or something).
But load average per spindle is working.
http://www.paulbeard.org/cacti/graph_160.html
http://www.paulbeard.org/cacti/graph_161.html
Now to see if I can export these and use them somewhere else. Sadly, I think my options are limited: last I looked Linux didn't support these values. |

Fine, but what solved the issue?
For the slope: simply change ds-type from GAUGE to COUNTER and you should be done. You need to change this for the Data Template. All existing rrds would need some rrdtool tune --data-source-type <ds-name>:<ds-type> to reflect this

When i try to load the xml of the example ("Chapter I: Building raw XML file") i get these errors:

any idea? |

| I whacked some rrd files w/o thinking of the consequences and can't recreate the data sources. How can I clear that up so I can redo those graphs for disk reads/writes? |

Perhaps lack of my understanding of english language, but what exactly is broken? The rrd files or the Data Template? What is left? Any backups in place?

| Heh. What I meant to say was I removed the RRD files and now I can't re-create the graphs: the data sources are shown as already in use. How can I clean that up? |

As all data is gone, please remove the according Graphs from Graph Management and recreate from the Devices by Create Graphs for this Host

The data items I want to graphs are greyed out, as though they are already being graphed. |

I think you need to delete the data sources then try to create the graphs again. |

<strike>I have done that. It appears I'll have to do something in the database: I just don't know what.</strike>
Looks like this is OK now. I just recreated the graphs after find thme *not* greyed out. |
