[rrd-users] Empty sections in AREA on graph, but values in database

[Thomas Brinkmann]

 

Hello,

i have problems with a graph.

i want to show the state of a switch (0 = Off, 1 = 1, 2=2, 3=3) via the AREA commad. but in my graph the area is empty sometimes.

 

Here is my code:

RRDs::graph($tmpfile,
  @opts,
  "DEF:stufe=$rrd:stufe:LAST",
  "CDEF:stufe1_flag=stufe,1,EQ,INF,UNKN,IF",
  "CDEF:stufe2_flag=stufe,2,EQ,INF,UNKN,IF",
  "CDEF:stufe3_flag=stufe,3,EQ,INF,UNKN,IF",
  "CDEF:stufe0_flag=stufe,0,EQ,INF,UNKN,IF",
 
  "AREA:stufe0_flag#7c6767:Stufe 0 AUS \\t",
  "AREA:stufe1_flag#98FB98:Stufe 1 \\t",
  "AREA:stufe2_flag#fafa78:Stufe 2 \\t",
  "AREA:stufe3_flag#fd6969:Stufe 3 \\t",

  "DEF:bypass=$rrd:bypass:AVERAGE",
  "CDEF:bypass_flag=bypass,1,EQ,50,UNKN,IF",
  "AREA:bypass_flag#ffe0e0:Bypass offen \\l",

  "DEF:wrgZu=$rrd:wrgZu:AVERAGE",
  "LINE2:wrgZu#000000:WRG - zuluftseitig (in % )",
  "VDEF:wrgZulast=wrgZu,LAST",
  "GPRINT:wrgZulast:     JETZT \%.1lf

 

When look into the xml exported rrd database i can see that the right values ("1") is stored continouly in the database, so i see no reaseon why i have interrupts in the green background of the graph.

How can helpme out or explain why i have emtpy sections in my graph ?

 

Here is the graph: http://www.dreamies.de/show.php?img=6lxz5otgz81.gif

 

thank you,

 

Thomas
