Not terribly efficient. I have about 500 devices that I monitor. I have one master config, with Include: directives for all of the devices. I'm running forks: 40. That runs 40 polling sessions at a time. Once the polling is done, the rrd writing is all single-threaded. What helped us the most was setting up a stripe-set for the rrd files. With 4 15K rpm sas drives, a 4 member stripe set cut our writing time from almost 4 minutes to about 40 seconds. -- Daniel J McDonald, CCIE #2495, CISSP #78281, CNX Austin Energy http://www.austinenergy.com
