NSClient

What's Changed

This build removes the option of specifying connection details on command line instead it expands the profiles command. So there is now a profile command to managed saved profiles.

check_nsclient profile list

│ default │ https://localhost:8443 │ yes      │ yes     │ yes       │
╰─────────┴────────────────────────┴──────────┴─────────┴───────────╯

It also ads a somewhat working client mode:

What's Changed

• Added even more client commands by @mickem in https://github.com/mickem/nscp/pull/1086

You can now login/logout using the auth command which will store the token in credential store:

check_nsclient nsclient --insecure auth login --username admin --password PASSWORD

After this you no longer need to specify the username and password:

What's Changed

Added query command to check_nsclient command and attached client only binaries to release.

This means you can now inventory queries (check_commands):

check_nsclient nsclient --insecure --password PASSWORD queries list
╭───────────────────────┬──────────────╮

As with most commands you can get output as json:

check_nsclient --output json nsclient --insecure --password PASSWORD queries execute check_cpu
{
  "command": "check_cpu",
  "lines": [
    {
      "message": "OK: CPU load is ok.",
      "perf": {
        "total 1m": {
          "value": 20.0,
          "unit": "%",
          "warning": 80.0,
          "critical": 90.0,
          "minimum": null,
          "maximum": null
        },
        "total 5s": {
          "value": 23.0,
          "unit": "%",

          "maximum": null
        }
      }
    }
  ],
  "result": 0
}

As well as in the nagios format:

check_nsclient nsclient --insecure --password PASSWORD queries execute-nagios check_cpu
