[rrd-users] Re: How do I get the current time in the graph

[Watkins, K (Kobe)]

Hi Rob,

I use this on the bottom of all my graphs when using rrdcgi:

COMMENT:"Data graphed from <RRD::TIME::STRFTIME START <RRD::CV LENGTH>
<RRD::CV END> '%H\:%M %e/%b/%Y'> to <RRD::TIME::STRFTIME END <RRD::CV
LENGTH> <RRD::CV END> '%H\:%M %e/%b/%Y'>"

Which produces:

Data graphed from 09:41 24/Aug/2005 to 09:41 25/Aug/2005

Where:

END = now
LENGTH = end-1d

I guess you could use the RRD::TIME::NOW function to get the current
time, but this would only work if you're using rrdcgi to generate the
graphs.

Subject: [rrd-users] How do I get the current time in the graph


Hi,

I would like to put a timestamp in the graph so we know at what time the

graph was created.  I have looked through the docs and tried to play 
with the TIME and LTIME rpn values, but have not been successful at 
setting a variable with the value of the current time.  Does anyone have

an example of of setting a variable with the time of day?

Thanks.
