[RFE] configurable sesame publish rate (sesame publishing too often)
Last modified: 2011-08-12 12:02:08 EDT
# rpm -q sesame sesame-0.4.3108-1.el5 cumin=# select sysimage_id,qmf_update_time from sysimage_stats order by sysimage_id,qmf_update_time limit 15; sysimage_id | qmf_update_time -------------+--------------------- 1 | 2009-02-19 14:26:42 1 | 2009-02-19 14:26:47 1 | 2009-02-19 14:26:52 1 | 2009-02-19 14:26:57 1 | 2009-02-19 14:27:02 1 | 2009-02-19 14:27:07 1 | 2009-02-19 14:27:12 1 | 2009-02-19 14:27:17 1 | 2009-02-19 14:27:22 1 | 2009-02-19 14:27:27 1 | 2009-02-19 14:27:32 1 | 2009-02-19 14:27:37 1 | 2009-02-19 14:27:42 1 | 2009-02-19 14:27:47 1 | 2009-02-19 14:27:52 (15 rows) I think sesame is publishing data too often. It's apparently at a rate of .2Hz, which won't scale well. We need a way to adjust/configure the rate.
Solution committed upstream at revision 3586.
Simple script I use to test this: # yum install sesame echo -n "`cat /etc/redhat-release` " uname -m rpm -q sesame sesame --help 2>&1 | grep interval And it's output: --------------------------------------------------------------- Red Hat Enterprise Linux Server release 5.4 (Tikanga) i686 sesame-0.7.3826-3.el5 --pub-interval N (10) Publish interval in seconds --------------------------------------------------------------- Red Hat Enterprise Linux Server release 5.4 (Tikanga) x86_64 sesame-0.7.3826-3.el5 --pub-interval N (10) Publish interval in seconds --------------------------------------------------------------- Red Hat Enterprise Linux AS release 4 (Nahant Update 8) i686 sesame-0.4.3153-2.el4 --------------------------------------------------------------- Red Hat Enterprise Linux AS release 4 (Nahant Update 8) x86_64 sesame-0.4.3153-2.el4 --------------------------------------------------------------- So I will wait for RHEL4 packages and re-test then.
root@rhel4:~# sh sesame-test Red Hat Enterprise Linux AS release 4 (Nahant Update 8) i686 sesame-0.7.3826-5.el4 --pub-interval N (10) Publish interval in seconds [root@rhel4x ~]# sh sesame-test Red Hat Enterprise Linux AS release 4 (Nahant Update 8) x86_64 sesame-0.7.3826-5.el4 --pub-interval N (10) Publish interval in seconds
Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: Previously, sesame was publishing data at a very high rate (of 0.2Hz). With this update, the rate is adjusted to a proper level.
