Hello,
I have a test machine that is a nuc6 with an i5 and 32G of ram and SSD
disks.
It is configured as a single host environment with Self Hosted Engine VM.
Both host and SHE are CentOS 7.2 and oVirt version is 3.6.6.2-1.el7
I notice that having 3 VMs powered on and making nothing special (engine
VM, a CentOS 7 VM and a Fedora 24 VM) the ovirt-ha-agent process on host
often spikes its cpu usage.
See for example this quick video with top command running on host that
reflects what happens continuously.
https://drive.google.com/file/d/0BwoPbcrMv8mvYUVRMFlLVmxRdXM/view?usp=sha...
Is it normal that ovirt-ha-agent consumes all this amount of cpu?
Going into /var/log/ovirt-hosted-engine-ha/agent.log I see nothing special,
only messages of type "INFO". The same for broker.log
Thanks,
Gianluca

Does the spikes correlates with info messages on extracting the ovf?

Hi,
did you found a solution or cause for this high CPU usage?
I have installed the self hosted engine on another server and there is
no VM running but ovirt-ha-agent uses heavily the CPU.

Yes, it's due to the fact that ovirt-ha-agent periodically reconnects over
json rpc and this is CPU intensive since the client has to parse the yaml
API specification each time it connects.

Simone, reusing the connection is good idea anyway, but what you describe
is
a bug in the client library. The library does *not* need to load and parse
the
schema at all for sending requests to vdsm.
The schema is only needed if you want to verify request parameters,
or provide online help, these are not needed in a client library.
Please file an infra bug about it.

Here is a patch that should eliminate most most of the problem:
https://gerrit.ovirt.org/65230
Would be nice if it can be tested on the system showing this problem.

Simone, reusing the connection is good idea anyway, but what you =

a bug in the client library. The library does *not* need to load and

The schema is only needed if you want to verify request parameters,

This is orthogonal issue.
Does schema validation matter then if there would be only one
connection
at the start up?
Loading once does not help command line tools like vdsClient, hosted-engine
and
vdsm-tool.

this is a video of 1 minute with the same system as the first post, but in
4.0.3 now and the same 3 VMs powered on without any particular load.
It seems very similar to the previous 3.6.6 in cpu used by ovirt-ha-agent.
https://drive.google.com/file/d/0BwoPbcrMv8mvSjFDUERzV1owTG8/view?usp=sha...
Enjoy Nir ;-)
If I can apply the patch also to 4.0.3 I'm going to see if there is then a
different behavior.
Let me know,

different behavior.
Let me know,
I'm trying it right now.
Any other tests will be really appreciated.
The patch is pretty simply, you can apply that on the fly.
You have to shutdown ovirt-ha-broker and ovirt-ha-agent; then you could
directly edit
/usr/lib/python2.7/site-packages/api/vdsmapi.py
around line 97 changing from
loaded_schema = yaml.load(f)
to
loaded_schema = yaml.load(f, Loader=yaml.CLoader)
Please pay attention to keep exactly the same amount of initial spaces.
Then you can simply restart the HA agent and check.
Gianluca

I'm trying it right now.
Any other tests will be really appreciated.
The patch is pretty simply, you can apply that on the fly.
You have to shutdown ovirt-ha-broker and ovirt-ha-agent; then you could
directly edit
/usr/lib/python2.7/site-packages/api/vdsmapi.py
around line 97 changing from
loaded_schema = yaml.load(f)
to
loaded_schema = yaml.load(f, Loader=yaml.CLoader)
Please pay attention to keep exactly the same amount of initial spaces.
Then you can simply restart the HA agent and check.

What I've done (I didn't read your answer in between and this is a test
system not so important... )
set to global maintenance
patch vdsmapi.py
restart vdsmd
restart ovirt-ha-agent
set maintenance to none
And a bright new 3-minutes video here:
https://drive.google.com/file/d/0BwoPbcrMv8mvVzBPUVRQa1pwVnc/view?usp=sha...
It seems that now ovirt-ha-agent or is not present in top cpu process or at
least has ranges between 5% and 12% and not more....

Now I also restarted ovirt-ha-broker just in case

or

5-12% is probably 10 times more than needed for the agent, profiling
should tell us where time is spent.
Since the agent depends on vdsm, we can reuse vdsm cpu profiler, see
lib/vdsm/profiling/cpu.py. It is not ready yet to be used by other
applications,
but making it more general should be easy.

it worked for me as well - load avg. < 1 now, ovirt-ha-agent pops up in
top periodically, but not on top using 100% CPU all the time anymore.
thanks!

Like all the other clients (vdsm migration code:-)
This is orthogonal issue.
Does schema validation matter then if there would be
only one connection at the start up?
Loading once does not help command line tools like
vdsClient, hosted-engine and
vdsm-tool.

this is a video of 1 minute with the same system as the first
post, but in 4.0.3 now and the same 3 VMs powered on without
any particular load.
It seems very similar to the previous 3.6.6 in cpu used by
ovirt-ha-agent.

Enjoy Nir ;-)
If I can apply the patch also to 4.0.3 I'm going to see if
there is then a different behavior.
Let me know,
I'm trying it right now.

<div>Simone,
reusing the
connection is
good idea
anyway, but
what you
describe is </div>
<div>a bug in
the client
library. The
library does
*not* need to
load and parse
the</div>
<div>schema at
all for
sending
requests to
vdsm.</div>
<div><br>
</div>
<div>The
schema is only
needed if you
want to verify
request
parameters,</div>
<div>or
provide online
help, these
are not needed
in a client
library.</div>
<div><br>
</div>
<div>Please
file an infra
bug about it.</div>

The patch is pretty simply, you can apply that on the fly.
You have to shutdown ovirt-ha-broker and ovirt-ha-agent; then you could
directly edit
/usr/lib/python2.7/site-packages/api/vdsmapi.py
around line 97 changing from
loaded_schema = yaml.load(f)
to
loaded_schema = yaml.load(f, Loader=yaml.CLoader)
Please pay attention to keep exactly the same amount of initial spaces.
Then you can simply restart the HA agent and check.
Hello,
I'm again registering high spikes of ovirt-ha-agent with only 2-3 VMs up
and with almost no activity
The package of the involved file
/usr/lib/python2.7/site-packages/api/vdsmapi.py
is now at veriosn vdsm-api-4.19.4-1.el7.centos.noarch and I see that the
file contains this kind of lines
129 try:
130 for path in paths:
131 with open(path) as f:
132 if hasattr(yaml, 'CLoader'):
133 loader = yaml.CLoader
134 else:
135 loader = yaml.Loader
136 loaded_schema = yaml.load(f, Loader=loader)
137
138 types = loaded_schema.pop('types')
139 self._types.update(types)
140 self._methods.update(loaded_schema)
141 except EnvironmentError:
142 raise SchemaNotFound("Unable to find API schema file")
So there is a conditional statement...
How can I be sure that "loader" is set to "yaml.CLoader" that was what
in
4.0 was able to lower the cpu usage of ovirt-ha-agent?
Thanks,

Hi Gianluca,
You can run this on the host:
$ python -c "import yaml; print 'CLoader:', hasattr(yaml,
'CLoader')"
CLoader: True
If you get "CLoader: False", you have some packaging issue, CLoader
is available on all supported platforms.

There are two issues in this video:
- Memory leak, ovirt-ha-agent is using 1g of memory. It is very unlikely
that it needs so much memory.
- Unusual cpu usage - but not the kind of usage related to yaml parsing.
I would open two bugs for this. We have seen the first issue few month ago,
and
we did nothing about it so the memory leak was not fixed.
To understand the unusual cpu usage, we need to integrate yappi into
ovirt-ha-agent,
and do some profiling to understand where cpu time is spent.
Simone, can you do something based on these patches?
https://gerrit.ovirt.org/#/q/topic:generic-profiler
I hope to get these patches merged soon.

On 4.1.1, the 96% of the cpu time of ovirt-ha-agent is still spent in
connect() in /usr/lib/python2.7/site-packages/vdsm/jsonrpcvdscli.py
and the 95.98% is in Schema.__init__
in /usr/lib/python2.7/site-packages/vdsm/api/vdsmapi.py
So it's still the parsing of the api yaml schema.
On master we already merged a patch to reuse an existing connection if
available and this should mitigate/resolve the issue:
https://gerrit.ovirt.org/73757/
It's still not that clear why we are facing this kind of performance
regression.

Does this mean that I could try to patch the
ovirt_hosted_engine_ha/lib/util.py file also in my 4.1.1 install and
verify if it solves...?
Or do I have to wait an official patched rpm?

Yes, we are going to fix that too (

hosted-engine and
vdsm-tool.
none of the other tools is using json-rpc.
hosted-engine-setup is, and sooner or later we'll have to migrate also the
remaining tools since xmlrpc has been deprecated with 4.0

Yes, we are going to fix that too ( https://bugzilla.redhat.com/
show_bug.cgi?id=1349829 )
that’s great! Also al the other vdsClient uses?:-)
https://gerrit.ovirt.org/#/c/62729/
What is that periodic one call anyway? Is there only one? Maybe we
don’t
need it so much.
Currently ovirt-ha-agent is periodically reconnecting the hosted-engine
storage domain and checking its status. This is already on jsonrpc.
In 4.1 all the monitoring will be moved to jsonrpc.
but it would require also https://bugzilla.redhat.com/
show_bug.cgi?id=1376843 to be fixed.
This is less good. Well, worst case you can reconnect yourself, all you
