The variable CURRENT_MAXIMUM_VALUE is simply substituted with the maximum value set for the current data source. Your CDEF looks almost right, except it is missing the "percent part":
| Code: | | CURRENT_DATA_SOURCE,8,*,CURRENT_MAXIMUM_VALUE,/,100,* |

Hi Rax
Can You also add Current max Value indicated in the graph not in the data source
Thanks |

I did what you said, but it doesn't work. I also created a test CDEF that just contains CURRENT_MAXIMUM_VALUE, and it causes the graph not to be displayed. Is CURRENT_MAXIMUM_VALUE a derived value? Or does it have to be set in the data source page? (Mine says 100000000, which explains the absurdly low numbers i've been getting on my 1.544 mbit T1's) |

For this feature to work, you need to have a data source selected in the graph item that you use this CDEF in. So, if you use this CDEF on a graph item it must have a data source.

Done. I also renamed 'CURRENT_MINIMUM_VALUE' to 'CURRENT_DS_MINIMUM_VALUE' and 'CURRENT_MAXIMUM_VALUE' to 'CURRENT_DS_MAXIMUM_VALUE'. If you forget to select a data source, it won't break your graph anymore, just display a nan.

The CDEF itself is working properly. I think the problem is that the Data Source's Maximum Value isn't getting set to |query_ifSpeed|. All my lines are showing up as 100000000 as the Maximum Value, instead of the actual values.
Also, when updating the Data Source's Maximum Value for the interfaces, I can only update traffic_in. traffic_out never gets updated. |

There is one misunderstanding present in whole 0.8.x line. Interface speed is used for setting data source maximum value. It's not correct since interface speed is measured in bits/sec while maximum value is related to counter which is used for calculation values in bytes/sec. For example maximum value for 10Mb Ethernet interface should be set to 1250000 (not 10000000). Maximum values are set 8 times too high what may cause spikes on graphs.

|

New Install of 20040201 build. It finds my snmp, php and rrdtool, then I select the appropriate snmp version (UCD-SNMP) and then click final. I get the following error.
Fatal error: Call to undefined function: xml_parser_create() in /var/www/cacti-0.8.5/lib/xml.php on line 31
Nothing more...
Database created without any errors. Using php ver 4.1.2 (Docs say 4.1+) |

And I got the same error 0.8.4!
Fatal error: Call to undefined function: xml_parser_create() in /var/www/cacti-0.8.4/lib/xml.php on line 31
I guess I'll have to find out what I'm missing... =( |
