1.17.1. Monitoring#

Starting with LinOTP 2.8.1 a new monitoring API was introduced. It can be used to query information about license, configuration as well as token and user numbers.

The comprehensive API documentation can be found here:

https://www.linotp.org/doc/api/linotp.controllers.monitoring.html

The basic API call is:

https://<LINOTP>/monitoring/<MonitoringController>?session=SESSIONCOOKIE[&PARAM1][&PARAM2][..]

Tip

Detailed information about the handling of the session cookie can be found at system_controller

Perform Queries#

Displays the number of configuration entries in the LinOTP database.

https://<LINOTP>/monitoring/config?session=SESSIONCOOKIE

Example:

https://linotp.example.net/monitoring/config?session=45e939b02[...]

{
  "version": "LinOTP 2.9",
  "jsonrpc": "2.0802",
  "result": {
     "status": true,
     "value": {
        "sqlresolver": 1,
        "total": 176,
        "realms": 4,
        "passwdresolver": 0,
        "sync": true,
        "synctime": "2016-07-15 12:53:15.421162",
        "policies": 13,
        "netto": 56,
        "ldapresolver": 1,
        "now": "2016-07-15 13:07:25.138295"
     }
  },
  "id": 1
}

License#

Displays support and subscription information and can be used to monitor whether the number of active tokens surmount the license or how many tokens can still be assigned within the limits of the license.

https://<LINOTP>/monitoring/license?session=SESSIONCOOKIE

Example:

In this example the license is issued for 1000 active tokens. 780 tokens are active right now so 220 additional tokens can be used.

https://linotp.example.net/license/config?session=45e939b02[...]

{
  "version": "LinOTP 2.9",
  "jsonrpc": "2.0802",
  "result": {
     "status": true,
     "value": {
        "token-num": 1000,
        "token-active": 780,
        "token-left": 220
     }
  },
  "id": 1
}

Storage encryption#

Checks whether local key or HSM is used to encrypt new entries written to the database.

https://<LINOTP>/monitoring/storageEncryption?session=SESSIONCOOKIE

Example

https://linotp.example.net/license/storageEnrcyption?session=45e939b02[...]


{
  "version": "LinOTP 2.9",
  "jsonrpc": "2.0802",
  "result": {
     "status": true,
     "value": {
        "cryptmodul_type": "DefaultSecurityModule",
        "cryptmodul_name": "Default",
        "encryption": true
     }
  },
  "id": 1
}

Tokens#

Shows tokens per realm. Filters can be applied regarding the status of the token or which realm is displayed.

Available filters:

realms

show tokens from certain realms.

active

show only active tokens.

inactive

show only inactive tokens.

assigned

show only tokens assigned to users.

unassigned

show only tokens not assigned to any user.

The states can be combined like this:

...status=assigned%26active
https://<LINOTP>/monitoring/tokens?session=SESSIONCOOKIE[&status=[assigned|unassigned][active|inactive][&realm=REALM1[,REALM2]]

Example - display tokens of all realms

Please mind, that the total numbers of tokens can be smaller than the sum of the tokens per realm - one token can be assigned to more than one realm. So if a token is in realm1 and realm2 and realm3 it is only counted once in total.
