The Tacacs plugin collects successful tacacs authentication response times from tacacs servers such as Aruba ClearPass, FreeRADIUS or tac_plus (TACACS+). It is primarily meant to monitor how long it takes for the server to fully handle an auth request, including all potential dependent calls (for example to AD servers, or other sources of truth for auth the tacacs server uses).
In addition to the plugin-specific configuration settings, plugins support additional global and plugin configuration settings. These settings are used to modify metrics, tags, and field or create aliases and configure ordering, etc. See the CONFIGURATION.md for more details.
# Tacacs plugin collects successful tacacs authentication response times.
[[inputs.tacacs]]
## An array of Server IPs (or hostnames) and ports to gather from. If none specified, defaults to localhost.
# servers = ["127.0.0.1:49"]
## Request source server IP, normally the server running telegraf.
# request_ip = "127.0.0.1"
## Credentials for tacacs authentication.
username = "myuser"
password = "mypassword"
secret = "mysecret"
## Maximum time to receive response.
# response_timeout = "5s"The field "response_status" is either a translated raw code returned by the tacacs server, or filled by telegraf in case of a timeout.
| Field Value | Raw Code | From | responsetime_ms |
|---|---|---|---|
| AuthenStatusPass | 1 (0x1) | tacacs server | real value |
| AuthenStatusFail | 2 (0x2) | tacacs server | real value |
| AuthenStatusGetData | 3 (0x3) | tacacs server | real value |
| AuthenStatusGetUser | 4 (0x4) | tacacs server | real value |
| AuthenStatusGetPass | 5 (0x5) | tacacs server | real value |
| AuthenStatusRestart | 6 (0x6) | tacacs server | real value |
| AuthenStatusError | 7 (0x7) | tacacs server | real value |
| AuthenStatusFollow | 33 (0x21) | tacacs server | real value |
| Timeout | Timeout | telegraf | eq. to response_timeout |
The field responsetime_ms is response time of the tacacs server in milliseconds of the furthest achieved stage of auth. In case of timeout, its filled by telegraf to be the value of the configured response_timeout.
