Hi, While trying to use gmond to monitor our applications, we found some issues: - Metric collecting may take long time to finish, such examples include collecting master/slave status from LDAP, parsing web pages to get statistics. - Receiving metrics updating from other node may fail due to blocking metric collecting.
To avoid this blocking behavior, we tried to change gmond to multithread: - Main thread to collect metrics, we also have the metric collection python script changed to be non-blocking - Dedicate thread to receive updates from other nodes. - Dedicated thread to server clients (gmetad/telnet, etc). Could you help review the patch? We'd like to contribute the patch to the community if multi-thread is a generally required features. Any comments will be appreciated. Thanks. p.s. Just to be curious, why ganglia was changed from multi-thread into single thread from 2..5.7 to 3.0? Cheers, Hang
