Hi,<br>
<br>
my first post to the list and to be honest: I havent followed this list<br>
and rrdtool development for many years though using it widely & every<br>
single day. It just worked to well ;)<br>
<br>
I created a little patch to make "rrdtool fetchj .." simply output json<br>
instead of text, attached.<br>
<br>
Intentions, the answers to why etc:<br>
- Target-Platforms are rather low-end (AMD Geode, OpenWRT Routers), so<br>
with rrdtool 1.3, 1.4 was dead slow in graphing on these low-ends during<br>
my tests.<br>
- avoid (another) shellscript or CGI to wrap "rrdtool fetch" output into<br>
JSON what I needed to feed jQuery/Flot in this case.<br>
- but "rrdtool fetch" does exactly what I need, with all it's benefits,<br>
fast, small data to transfer, right data, autoscaling etc.pp.<br>
<br>
<br>
Please let me know your thoughts, if it makes sense at all.<br>
I know for sure that a patch against an rather old version isn't perfect<br>
but it was as mentioned chosen precisely..<br>
<br>
Could also do it for current 1.4/trunk but it's currently not my goal<br>
because of serious performance-problems (which might have many other<br>
causes than rrdtool itself for sure!)<br>
<br>
<br>
best regards<br>
