Hi Team,
With the current implementation of gingerbase, the processor information
is empty for s390 architecture.
O/p of /plugins/gingerbase/host on one of the lpar with KVM for IBM z
systems:
{
"os_distro":"KVM for IBM z Systems",
"os_codename":"Z",
"os_version":"1.1.1",
"cpus":3,
"memory":4000559104
}
Note: cpu_model is not fetched for s390x architecture.
Additional Information which can be provided for benefit of end users:
Architecture Details: "architecture": "x86 or s390x or ppc etc"
CPU details(for x86 and s390x): Showing online cpus count and offline
cpus count(planned to use lscpu for x86 and s390x, not sure how to fetch
these details in power pc). Display offline CPUs only if any processors
are offline.
"cpus": {"online": <integer(online_cpus_count)>
"offline": <integer(offline_cpus_count)>}
Processor Type(s390x): shared and dedicated cpus
"cpus": {"online": <integer(online_cpus_count)>
"offline": <integer(offline_cpus_count)>
"shared": <integer(shared_cpus_count)>
"dedicated": <integer(dedicated_cpus_count)>}
Host Name(for all architecture): Currently IP address is displayed in
the new UI (below kimchi logo). Displaying host name would be more
meaningful.
Memory Details(s390x specific): In s390x architecture, we can have
online and offline memory.
example:
[root@ ~]# lsmem
Address Range Size (MB) State Removable Device
===============================================================================
0x0000000000000000-0x000000000fffffff 256 online no 0
0x0000000010000000-0x000000002fffffff 512 online yes 1-2
0x0000000030000000-0x000000007fffffff 1280 online no 3-7
0x0000000080000000-0x00000000ffffffff 2048 offline - 8-15
Memory device size : 256 MB
Memory block size : 256 MB*
**Total online memory : 2048 MB**
**Total offline memory: 2048 MB*
so memory would be split to include total online and total offline memory.
memory: {"online": <total_online_memory>, "offline":<total
offline memory>}
Virtualization Details(s390x specific):
Providing Hypervisor and Hypervisor Vendor details when virtualized.
Example Hypervisor: PR/SM , Hypervisor vendor: IBM.
Lpar Details: Lpar name and Lpar ID
"virtualization": {"hypervisor":"PR/SM",
"hypervisor_vendor": "IBM",
"lpar_name": "LP6",
"lpar_number":"22"}
So the o/p json of /plugins/gingerbase/host would look like below:
for x86:
{
"os_distro":"Fedora",
"architecture":"x86_64"
"cpu_model":"Intel(R) Core(TM) i5-3320M CPU @ 2.60GHz",
"cpus":{"online":3, "offline":2},
"os_version":"21",
"os_codename":"Twenty One",
"memory":7933894656
"host":<host_name>
}
for power:
Only change, addition of "architecture" and "host" information, unless
we decide to show offline cpus
for s390x:
{
"os_distro":"KVM for IBM z Systems",
"os_codename":"Z",
"os_version":"1.1.1",
"architecture": "s390x"
"cpu_model": "IBM / 2827 / 743 H43"
cpus: {"online":2,
"offline":2,
"shared":2,
"dedicated":0}
memory : {"online" : 2147483628,
"offline" : 2147483628}
"virtualization": {"hypervisor":"PR/SM",
"hypervisor_vendor": "IBM",
"lpar_name": "LP6",
"lpar_number":"22"},
"host":"zfwpc160"
}
