Zabbix Skripte Maintenance Host oder Gruppe

Dieses Thema ist noch nicht vollständig! Es wird noch daran gearbeitet!

Ab Zabbix 6.0 kann man einen API-Key statt Benutzernamen und Passwort nutzen,
ab Zabbix 6.4 muss man das sogar. Das Skript muss noch auf API-Key Nutzung umgebaut werden!
Für das UI-Skript wurde das schon gemacht: Host per Popup-Skript aus der Zabbix-Server Weboberfläche in Wartung setzen Ich habe unten eine neue Version als Test bereit gestellt, die ist aber noch nicht getestet

---

Die beiden Skripte nutze ich als Alertscripts und als Externalscripts direkt auf dem Zabbix Server.
Das Skript für die Hosts ist nahezu 1:1 das von

https://www.zabbix.org/wiki/Perl_script_to_add/remove_Maintenance

Ich habe nur den Fehler bei der Abfrage beseitigt (es wurden immer alle Hosts zurückgegeben, nicht nur der gewünschte).
Außerdem ignoriert es bei https Fehler mit selbst-signierten Zertifikaten.
Das Skript für die Gruppen ist das gleiche Skript nur angepasst an die Gruppen.

Einbindung in Zabbix Oberfläche

Unter

Administration => Scripts

habe ich folgende Skripte angelegt:

Im Detail:

Dadurch habe ich an jedem Host folgendes Menu (z.B. in der Problems-Ansicht):

So kann ich - falls ich mal wieder Updates einspiele und vergessen habe den Host in den Maintenance-Modus zu setzen - diese eben schnell nachholen.

Man kann das Skript auch natürlich auch aus anderen Programmen aufrufen - z.B. um aus dem Ticketsystem bei genehmigten Change die zugehörigen Systeme automatisch für den geplanten Zeitraum in den Wartungsmodus zu versetzen.

Nutzung in Actions

Das Gruppenskript nutze ich Actions um einen ganzen Standort in Wartung zu versetzen:

Im Detail ist das hier beschrieben:

https://znil.net/index.php?title=Zabbix_Standorte_Hostgruppen_bei_Nichterreichbarkeit_automatisch_in_den_Wartungsmodus_setzen_oder_daraus_entfernen

Mit oder ohne Datensammlung

In beiden Skripten gibt es eine Zeile

\"maintenance_type\":\"0\",

Die 0 bedeudet "With data collection". Wollt Ihr das ohne Datensammlung "Without data collection" so ändert die 0 auf eine 1:

\"maintenance_type\":\"1\",
