Problem I am having is that the data is only updated every 10 minutes. I configured the graph in /etc/xymon/hobbitgraph.d/somegraph.cfg - you can see I added the --step 600 option. My script runs every 10 minutes from the hobbitlaunch.d directory.
The data in the rrd file does not tie up though from the rrdtool dump. The last_ds is correct, but the actual value keeps returning NaN
- and hence the graph does not generate.
<minimal_heartbeat> 600 </minimal_heartbeat>
rrdtool tune --heartbeat can change minimal_heartbeat from 600 (default, used for 300s intervals) to 900 or higher. Ideally, the value should be identical to the LIFETIME value (if you're sending "status color+LIFETIME", try "man bb"), as it serves the same purpose as going purple: marking intervals of stale values as unknown. But there's a history of LIFETIME defaulting to 1800 seconds...
