# remote_users_fact
|
||||
|
||||
Rôle Ansible qui déploie un **local fact** comptant les sessions distantes par protocole (SSH, Citrix, Horizon) et évaluant la fiabilité en comparant avec `who`.

||||

||||

## Usage
|
||||
|
||||
```bash
|
||||
# Déploiement complet
|
||||
ansible-playbook -i inventories/hosts.yml site.yml
|
||||
|
||||
# Déploiement seul
|
||||
ansible-playbook -i inventories/hosts.yml site.yml --tags deploy
|
||||
|
||||
# Vérification seule (fact déjà déployé)
|
||||
ansible-playbook -i inventories/hosts.yml site.yml --tags validate,summary
|
||||
|
||||
# Sur un groupe spécifique
|
||||
ansible-playbook -i inventories/hosts.yml site.yml -l citrix_servers
|
||||
```

## Fact déployé
|
||||
|
||||
Accessible via `ansible_local.remote_users` :
|
||||
|
||||
```json
|
||||
{
|
||||
"timestamp": "2026-04-13T10:30:00Z",
|
||||
"sessions": {
|
||||
"ssh": 3,
|
||||
"citrix": 12,
|
||||
"horizon": 0,
|
||||
"total_by_protocol": 15,
|
||||
"who_remote": 14
|
||||
},
|
||||
"users_remote": "alice,bob,charlie",
|
||||
"reliability": {
|
||||
"ratio_who_over_total": 0.93,
|
||||
"verdict": "WHO_INF_TOTAL",
|
||||
"detail": "who manque 1 session(s) sans TTY"
|
||||
},
|
||||
"detection": {
|
||||
"citrix_vda_installed": true,
|
||||
"horizon_agent_installed": false,
|
||||
"ssh_method": "sshd_process_and_ss",
|
||||
"citrix_method": "ctxquery",
|
||||
"horizon_method": "fallback_ports"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Verdicts
|
||||
|
||||
| Verdict | Signification |
|
||||
|---|---|
|
||||
| `FIABLE` | who == total → compteurs alignés |
|
||||
| `OK` | Écart ≤ 1 → tolérable |
|
||||
| `WHO_SUP_TOTAL` | who > total → protocole non surveillé |
|
||||
| `WHO_INF_TOTAL` | who < total → sessions headless sans TTY |
|
||||
| `WHO_SEUL` | total == 0 → protocoles non détectés |
|
||||
| `PROTO_SEUL` | who == 0 → sessions sans allocation TTY |
|
||||
| `NEUTRE` | 0 == 0 → aucune session |
|
||||
|
||||
## Utilisation dans d'autres playbooks
|
||||
|
||||
```yaml
|
||||
- hosts: all
|
||||
gather_facts: true
|
||||
tasks:
|
||||
- name: Refuser un déploiement si trop de sessions actives
|
||||
ansible.builtin.fail:
|
||||
msg: "{{ ansible_local.remote_users.sessions.total_by_protocol }} sessions actives, déploiement annulé"
|
||||
when: ansible_local.remote_users.sessions.total_by_protocol | int > 10
|
||||
```
