Saposcol, Solaris 10 and zones

[Former Member]

We are running a bunch of instances on Solaris 10 x86_64 in zones. Everything works great (including ZFS) but one issue is there:

saposcol always "sees" the full machine, means e. g. CPU usage is displayed not on a per-zone basis but only once for all zones.

Are there any plans on extending saposcol to support zone-specific data (such as IBM has recently done with AIX-micropartitioning and/or LPARS)? It would greatly improve resource management on those systems.

Hi Markus,

Saposcol gets its data from kstat, I haven't found futher information about Saposcol not seeing the full machine in the future. Maybe another colleague will give more details in the message you opened, if not here first.

Strange things happening...

I've seen the different filesystems (I'm using ZFS) some weeks ago but now I can also see only "/" and no time stamp.

I think this is a problem in saposcol and you/we should open an OSS call for that.

Maybe is the lastest kernel patch I have patch lvl 102.

I will open the call then.

Thank you again.

[markus_doehr2]

The kernel is not relevant here, the saposcol patch (which is separate from the kernel).

Mine here:

COLL 20.94 700 - V3.72 64Bit
14.09.2007                   164317

I ment that my version of saposcol is the one shipped in the kernel patch lvl 102.

But checking the sapsocol file there is and update from 11.09.2007.

I will update it first if it doenst work ill open the oss call.

Altough in the info provided there is nothing said about this.

Do you see them using "df -h" as user <sid>adm?

Same problem here , have you guys managed to see the file systems?

I can only see the / filesystem no other file systems are displayed.

Any help?

[markus_doehr2]

How does your zoneconfig look like?

--

Markus

[Former Member]

I didnt configure the zones, because the client has its own Solaria admins.

In case of cpus workload its not an issue for us yet because its only busy 10% all the time even in peaks times so we didnt even look in that.

But I wanted to configure CCMS alerts for FileSystems and the only one I see when i go to St06 Details - FileSys is / (root) , no other filesystems are displayed, maybe because this zoneconfig is not configured. Was not my task, but I need some info on it to tell the unix admin to configure it least for the file system.

Markus could you tell what should be done in this file to be able to see the file systems of each zone in their particulary sap instance?

[markus_doehr2]

If you see only "/" it´s a full root zone.

My zone look like

# zonecfg -z epjava export
create -b
set zonepath=/zone/epjava
set autoboot=false
add inherit-pkg-dir
set dir=/lib
end
add inherit-pkg-dir
set dir=/opt
end
add inherit-pkg-dir
set dir=/platform
end
add inherit-pkg-dir
set dir=/sbin
end
add inherit-pkg-dir
set dir=/usr
end
add fs
set dir=/usr/sap
set special=/usr/sap
set type=lofs
end
add fs
set dir=/dbdata/ETLDATA
set special=/dbdata/ETLDATA
set type=lofs
end
add fs
set dir=/dblog/ETLLOG
set special=/dblog/ETLLOG
set type=lofs
end
add net
set address=ْX.X.X.X
set physical=bge0
end
add net
set address=Y.Y.Y.Y
set physical=bge1
end
add device
set match=/dev/sound/*
end
add rctl
set name=zone.cpu-shares
add value (priv=privileged,limit=20,action=none)
end

If you just use "/" then you will only see "/" because it´s the only filesystem the zone sees. The zone is not aware of a /var or /usr because you only inherited "/".

Hello Markus,

We have the same problem and we didn't find any way to correct it yet.

Regards

François

[markus_doehr2]

it´s not a problem.

To make the machine see only a few number of CPUs you need to create a pool and assign it to the zone (see pooladm)

Hi

following are command for checking OS col

saposcol -l: Start OS Collector

saposcol -k: Stop OS Collector

saposcol -d: OS Collector Dialog Mode

saposcol -s: OS Collector Status

-Murali

Hi

You Can check saposcole ST06 or OS06 and check this
