通过刀获取节点属性

Question

I have a requirement where I need to get hostname, memory, cores, storage, packages installed for multiple nodes(~1k). I have approached the solution by using knife.

$ knife search node 'hostname:HostName1 OR hostname:HostName2 OR hostname:HostName3' -a hostname -a cpu.cores -a memory.total -a rpm -a filesystem.by_device -F j|jq '.'

And the typical output of this command is like;

    {
  "results": 3,
  "rows": [
    {
      "MyHostName1": {
        "hostname": "MyHostName1",
        "cpu.cores": 4,
        "memory.total": "15645184kB",
        "rpm": {
          "loger-multipath": [
            {
              "version": "0.4.9",
              "release": "123.el7",
              "arch": "x86_64"
            }
          ],
          "python": [
            {
              "version": "7.19.0",
              "release": "19.el7",
              "arch": "x86_64"
            }
          ]
        },
        "filesystem.by_device": {
          "/apps/logger/root_my-root": {
            "kb_size": "8125880",
            "kb_used": "2426760",
            "kb_available": "5263308",
            "percent_used": "32%",
            "mount_options": [
              "rw",
              "discard",
              "data=ordered"
            ],
            "uuid": "87ujrf56-6yu6-654r-yu43-uy67yg43ws67",
            "mounts": [
              "/"
            ]
          }
          }
        }
      }
    }

However, there are details which I do not need;

• How can we set the display sequence same as that of the attribute list in the command, ie hostname then core, memory…
• We get the file system names and their corresponding sizes, however, we are getting all the other tag values as well; how can we get just the file system name and the ( something similar to what we get from the df command; eg apps/logger/root_vg-apps: kb_size: 3997376 )
• The output of the rpm attribute gives us the rpm package name, architecture, version and release information, how can we concatenate the output of multiple attributes in a single line ( something similar to the output when we run the yum list installed command; eg loger-multipath.x86_64 0.4.9-123.el7 )

EDIT:

After much googling this is the progress:

knife search node 'HostName1 OR hostname:HostName2' -a cpu.cores -a memory.total -a filesystem.by_device -F j|jq '.rows[]|keys[] as $hostName|"\($hostName),\(.[$hostName]|."cpu.cores"),\(.[$hostName]|."memory.total"),\(.[$hostName]|."filesystem.by_device")"'

And the corresponding output

I know this seems a bit messy; any help is welcome

Answer 1

looking at the json provided in the question, it seems that your query does not use the right values for the key that you specify -- namely, hostname -- you specified hostname:HostName1 where it feels it needs to be hostname:MyHostName1 .

also, you can drop the node argument from the search command and specify it in the query, such as node:my.node.name .
