[oVirt] [CQ weekly status] [25-08-2019]
by Dusan Fodor
Hi,
This mail is to provide the current status of CQ and allow people to review
status before and after the weekend.
Please refer to below colour map for further information on the meaning of
the colours.
*CQ-4.2*: GREEN (#2)
Last failure was on 20-08 for ovirt-ansible-hosted-engine-setup. It was
caused by random network issue (fetching repo from github), retriggered job
for the change passed well.
*CQ-4.3*: GREEN (#2)
Last failure was on 20-08 for ovirt-ansible-hosted-engine-setup. It was
caused by random network issue, retriggered job for the change passed well.
*CQ-Master:* RED (#1)
Last failure was on 25-08 for ovirt-engine, caused by failed cloning of
engine repo (even with lately increased timeout value 20min). Related
ticket from last time was reopened.
Current running jobs for 4.2 [1], 4.3 [2] and master [3] can be found
here:
[1] http://jenkins.ovirt.org/view/Change%20queue%20jobs/job/ovirt
-4.2_change-queue-tester/
[2] https://jenkins.ovirt.org/view/Change%20queue%20jobs/job/ovirt
-4.3_change-queue-tester/
[3] http://jenkins.ovirt.org/view/Change%20queue%20jobs/job/ovirt
-master_change-queue-tester/
Have a nice week!
Dusan
-------------------------------------------------------------------------------------------------------------------
COLOUR MAP
Green = job has been passing successfully
** green for more than 3 days may suggest we need a review of our test
coverage
1.
1-3 days GREEN (#1)
2.
4-7 days GREEN (#2)
3.
Over 7 days GREEN (#3)
Yellow = intermittent failures for different projects but no lasting or
current regressions
** intermittent would be a healthy project as we expect a number of
failures during the week
** I will not report any of the solved failures or regressions.
1.
Solved job failures YELLOW (#1)
2.
Solved regressions YELLOW (#2)
Red = job has been failing
** Active Failures. The colour will change based on the amount of time the
project/s has been broken. Only active regressions would be reported.
1.
1-3 days RED (#1)
2.
4-7 days RED (#2)
3.
Over 7 days RED (#3)

[JIRA] (OVIRT-2782) Configure Jenkins to wait less and allocate

Description:
By default, Jenkins is configured to wait a few seconds before allocating a new node in a hope that a node in use to be freed. We can control this setting by setting
{code:java}
hudson.slaves.NodeProvisioner.initialDelay=0
{code}
We can also control the excessive workload threshold and force Jenkins to allocate slaves for jobs in the queue... but, because Jenkins computes the excess workload value (which decides if we need to allocate a new node) using an EMA, we set it's margins to higher values and it effectively lowers its threshold so that Jenkins will allocate nodes faster and in advance.
The recommended settings by the k8s plugin to spawn a node for every build in the queue:
{code:java}
-Dhudson.slaves.NodeProvisioner.initialDelay=0
-Dhudson.slaves.NodeProvisioner.MARGIN=50
-Dhudson.slaves.NodeProvisioner.MARGIN0=0.85

to `0`. But, because Jenkins computes the excess workload value (which decides if we need to allocate a new node) using an EMA, we also can control it's margins to lower its threshold so that Jenkins will allocate nodes faster and in advance.
The recommended settings by the k8s plugin to spawn a node for every build in the queue:
```
By default, Jenkins is configured to wait a few seconds before allocating a new node in a hope that a node in use to be freed. We can control this setting by setting `hudson.slaves.NodeProvisioner.initialDelay` to `0`. But, because Jenkins computes the excess workload value (which decides if we need to allocate a new node) using an EMA, we also can lower its threshold so that Jenkins will allocate nodes faster and in advance.
