Obtenir un token permanent :
La documentation stipule :
Do a HTTP POST request to https://plex.tv/users/sign_in.json (or https://plex.tv/users/sign_in.xml) with:
user[login] and user[password] form values in the body. For example: user%5Blogin%5D=plexusername&user%5Bpassword%5D=myplexpassword
HTTP header: X-Plex-Client-Identifier: a unique value for your client
HTTP header: X-Plex-Product: the name of your client
HTTP header: X-Plex-Version: the version of your client
Script (à exécuter une seule fois pour avoir un token permanent)
CLIENT_IDENTIFIER=$(uuidgen)
CLIENT_NAME="PLEX-API-CLIENT"
CLIENT_VERSION="1.0.0"
PLEX_USERNAME="sr-g"
PLEX_PASSWORD='mon_password_plex'
curl -X POST \
-u "${PLEX_USERNAME}:${PLEX_PASSWORD}" \
-H "Content-Type: application/xml; charset=utf-8" \
-H "Content-Length: 0" \
-H "X-Plex-Client-Identifier: $CLIENT_IDENTIFIER" \
-H "X-Plex-Product: $CLIENT_NAME" \
-H "X-Plex-Version: $CLIENT_VERSION" \
https://plex.tv/users/sign_in.xml
Le résultat est de la forme :

Ensuite il est possible de tester l’URL qui donne les sessions PLEX ainsi (format XML) :
curl 'http://192.168.8.4:32400/status/sessions?X-Plex-Token=MzWZxBTaHUqETWwxcsSM'
Et ainsi (format JSON, sera utilisé par Telegraf) :
curl -H "Accept: application/json" 'http://192.168.8.4:32400/status/sessions?X-Plex-Token=MzWZxBTaHUqETWwxcsSM'
Ou :
# http://192.168.8.4:32400/clients?X-Plex-Token=MzWZxBTaHUqETWwxcsSM'
# curl 'ws://localhost:32400/:/websockets/notifications?X-Plex-Token=MzWZxBTaHUqETWwxcsSM'
Résultat :

Le maître jedi Plo Koon et ses hommes sont pris à parti par une nouvelle arme Séparatiste dévastatrice. Ils subissent de lourdes pertes mais ne peuvent battre en retraite.

Il suffit ensuite de mapper la configuration Telegraf avec ces données : déclenchement de l’URL en mode “json”, extraction de la valeur “size” qui contient donc le nombre de flux en cours de diffusion depuis le serveur.
[[inputs.httpjson]]
name = "plex"
servers = [ "http://192.168.8.4:32400/status/sessions?X-Plex-Token=MzWZxBTaHUqETWwxcsSM" ]
response_timeout = "5s"
## HTTP method to use: GET or POST (case-sensitive)
method = "GET"
tag_keys = [ "size" ]
[inputs.httpjson.headers]
Accept = "application/json"
Sous Grafana il suffit ensuite d’ajouter un “SingleStat panel” avec la requête suivante (le nom “MediaContainer_plex” vient de la balise du XML de status auquel est concatané le “name” défini en configuration Telegraf ci-dessus) :
SELECT last("MediaContainer_size") FROM "httpjson_plex" WHERE $timeFilter GROUP BY "host"
