[rrd-users] How can i get <last_ds> counter value from rrd file?

[jayashree]

Hi, 
 
I am interested in getting the counter value stored in <last_ds> in the rrd
file. Any rrd function which can help me?
 
 
The idea is, i dont have response from the router at a certain point and I
want to log a zero in my graph. So to achieve this, I am trying to get the
last counter value stored in <last_ds> in my rrd file.  If there is a better
way to handle this problem of updating my rrd file with a '0' when i dont
have response from the device, please let me know.
 
Thanks,
jayashree
