There is a bug of javascript in “Create New Graph Page”.

To fix this bug, you may modify the php file “html.php” and “html_utility.php” at <cacti directory>/lib/.

Change all the code from “function gotoPage” to “function goto$page_var”.

類型:如果輸入數據依序為 98 100 98:
GAUGE(個別值,像CPU loading):產生圖形時畫 98 100 98
COUNTER (累計值,像流量資料):產生圖形時畫 2 -2
DERIVE (累計值,像流量資料),小於0畫0:產生圖形時畫 2 0
ABSOLUTE 如同 COUNTER,但 COUNTER 可能 overflow(數值過大),所以會取絕對值
補充說明,COUNTER/DERIVE/AVSOLVTE 雖是取差值,但會再除以兩次間隔間的秒數,如上 COUNTER 例,兩次間隔間為 300 秒,那畫出來的就是 2/300,-2/300 的值

1) Change the “locale” to “cht”.

2) Change the “CodePage” to 950.

If the chinese word still cannot be display, you can try to change another font. It’s work for me.
