<div dir="ltr">The number in rrdfeed.txt might be in the in-memory RRD buffer. Check the timestamp on the RRD file and see if it's older than that of rrdfeed.txt. From my experience, it seems that if you display the graph in Xymon, the buffer gets flushed and you can then get up-to-date data from the RRD file.<div>
