当一套工具有一个好的Web UI可以使用时，有时候会忘记CLI怎麽下
透过nomad job status 可以查看所有job的状态
$ nomad job status
ID Type Priority Status Submit Date
java-batch batch 50 dead 2021-09-04T00:59:17+08:00
erp service 50 running 2021-09-07T22:51:48+08:00
XXXXXXX service 50 dead 2021-09-03T11:02:47+08:00
test service 50 running 2021-09-03T11:22:34+08:00
webserv service 50 running 2021-08-27T08:38:14+08:00
web-standby service 50 running 2021-08-27T08:38:56+08:00
加上ID可以查看该job的详细资讯: nomad job status erp
$ nomad job status erp
ID = erp
Name = erp
Submit Date = 2021-09-07T22:51:48+08:00
Type = service
Priority = 50
Datacenters = Nomad
Namespace = default

Job evaluation是一个job的调度状态，可以透过参数 -evals查看，
例:以下这个job, 一开始是 job-register, 过程有alloc-failure, 再到deployment-watcher
如果有Placement Failures=true,的情况可以使用 nomad eval status EvaluationsID来查看
$ nomad job status -evals erp
ID = erp
Name = erp
Submit Date = 2021-09-07T22:51:48+08:00
Type = service
Priority = 50
Datacenters = Nomad
Namespace = default
Status = running
Periodic = false
Parameterized = false
Summary
Task Group Queued Starting Running Failed Complete Lost
webfront 0 0 2 2 0 0

Job allocation是一个job的被分配後的状态，包含cpu, memory, disk等，
job allocation失败也会有log资讯
可以透过nomad alloc status AllocationID来查看
$ nomad alloc status 07152288
ID = 07152288-c0f0-dc4c-3133-110c38ea2c1f
Eval ID = e9e513e1

Node ID = 970f4da9
Node Name = nomad-worker
Job ID = erp
Job Version = 0
Client Status = failed
Client Description = Failed tasks
Desired Status = stop
Desired Description = alloc was rescheduled because it failed
Created = 26m27s ago
Modified = 25m6s ago
Deployment ID = 263de268
Deployment Health = unhealthy
