Hi Richard,
I have been trying, with help from Randy, Trevor and Steve, to run some
experiments on an internal autobuilder instance to collect host data
during builds for signs of io latency.
Initially i modified yocto-autobuilder-helper/config.json and added the
following 3 lines to existing templates (and created a commit) that were
being used so that the builds would start collecting the data.
+ "BB_HEARTBEAT_EVENT = '5'",
+ "BB_LOG_HOST_STAT_ON_INTERVAL = '1'",
+ "BB_LOG_HOST_STAT_CMDS = 'pwd; ls'"
I also created a template in yocto-autobuilder-helper/config.json
+ "data-collect" : {
+ "BUILDINFO" : true,
+ "BBTARGETS" : "core-image-minimal",
+ "extravars" : [
+ "BB_HEARTBEAT_EVENT = '5'",
+ "BB_LOG_HOST_STAT_ON_INTERVAL = '1'",
+ "BB_LOG_HOST_STAT_CMDS = 'pwd; ls'"
+ ]
+ },
and modified a builder to use the template:
"beaglebone-alt" : {
- "MACHINE" : "beaglebone-yocto",
- "TEMPLATE" : "altcfg-hw"
+ "MACHINE" : "qemux86-64",
+ "TEMPLATE" : "data-collect"
},
Restarted both the controller and the worker, and started the
beaglebone-alt build. Once the build started, i checked the conf file in
the build directory but those lines were not appended to the local.conf
file and hence no log files.
In summary, I have been trying to get the 3 lines from the "extravars"
above to appear in one of the local.conf files. However none of the
builds seems to have been altered.
I am wondering if the changes that I've made are even being picked up by
the controller. Am I missing something?
Is there an easier way to update the conf files?
Initially I'd like collect data on a single node and scale it to all the
nodes. Any ideas/suggestions are welcome!
Sincerely,
Sakib Sajal
