RVC使用指南（五）-性能服务

看了就要关注我，哈哈~

本文讨论与vSAN性能服务相关的命令。这些命令用于启用和配置vSAN性能服务，并收集与性能相关的信息。

vsan.perf.cluster_info
vsan.perf.resync_dashboard
vsan.perf.stats_object_create
vsan.perf.stats_object_info
vsan.perf.stats_object_delete
vsan.perf.stats_object_setpolicy

vsan.perf.cluster_info ~cluster

vSAN性能服务监视Virtual SAN群集，主机，磁盘和VM的性能。在启用Virtual SAN性能服务之前，请确保正确配置了群集并且没有未解决的运行状况问题。vsan.perf.cluster info命令使你可以知道是否存在未解决的问题。

示例1-显示主机信息

> vsan.perf.cluster_info ~cluster
+------------------+--------------+--------+
| Hostname         | Role         | Issues |
+------------------+--------------+--------+
| vesx2.virten.lab | Agent        | None   |
| vesx1.virten.lab | Agent        | None   |
| vesx3.virten.lab | CMMDS Master | None   |
+------------------+--------------+--------+

vsan.perf.resync_dashboard [-r] ~cluster|~host

此命令显示正在进行镜像同步时发生的情况。如果主机发生故障或进入维护模式，则应在此处查看重新同步状态。该命令可以运行一次，也可以使用刷新时间。

-r, --refresh-rate: Refresh interval (in sec). Default is no refresh

示例1-数据同步仪表板

> vsan.perf.resync_dashboard ~cluster
Querying all objects in the system from vesx1.virten.lab ...
Got all the info, computing table ...
+-----------+-----------------+---------------+
| VM/Object | Syncing objects | Bytes to sync |
+-----------+-----------------+---------------+
+-----------+-----------------+---------------+
| Total     | 0               | 0.00 GB       |
+-----------+-----------------+---------------+

示例2-将主机置于维护模式后的数据同步仪表板。每10秒刷新一次：

> vsan.perf.resync_dashboard --refresh-rate 10 ~cluster
Querying all VMs on VSAN ...
Querying all objects in the system from esx1.virten.local ...
Got all the info, computing table ...
+-----------+-----------------+---------------+

vsan.perf.stats_object_create [-p|-o] ~cluster

Virtual SAN Performance Service收集的所有统计信息都存储在Stats DB对象中。该命令创建数据库对象并启用vSAN性能服务。

-p, --policy-str: Policy, expressed as string, e.g. vSAN format
-o, --policy: Policy, reference to SPBM profile

策略定义对象在Virtual SAN中的存储方式。可用值为：

hostFailuresToTolerate (Number of failures to tolerate)
forceProvisioning (If VSAN can't fulfill the policy requirements for an object, it will still deploy it)
stripeWidth (Number of disk stripes per object)
cacheReservation (Flash read cache reservation)
proportionalCapacity (Object space reservation)

示例1-使用默认策略创建vSAN Stats数据库：

> vsan.perf.stats_object_create ~cluster
Creating vSAN Stats DB object, which will enable vSAN Performance Service ...
Task: Enable vSAN performance service
New progress: 1%
Task result: success

示例2-使用自定义策略创建vSAN Stats数据库：

> vsan.perf.stats_object_create -p '(("hostFailuresToTolerate" i1) ("stripeWidth" i1))' ~cluster
VirtualMachineDefinedProfileSpec(profileData: {:extensionKey=>"com.vmware.vim.sps",:objectData=>"((\"hostFailuresToTolerate\" i1) (\"stripeWidth\" i1))"},profileId: ""
