| - | |||
| - | Per aggiungere un server o un servizio in Nagios bisogna andare sul panello di ammnistriazione Univention, Gestione Dominio [[https:// | ||
| - | |||
| - | ====Aggiungere un Servizio==== | ||
| - | In **Devices** trovate Nagios. E' qui che vengono aggiunti o modificati i servizi. Per quelli NRPE è importante che il nome del servizio sia uguale al nome del comando definito nel file dei comandi NRPE del server che si deve monitorare. | ||
| - | ====Aggiungere un Host==== | ||
| - | Andare su **Computers** per aggiungere un nuovo host oppure per modificare quelli attuali. Su **Options** del host attivate **Nagios support**. Salvare e poi rientrare per decidere i servizi del host che si vogliono monitorare in **Advanced Settings**. | ||
| - | ====Attivare le notifiche==== | ||
| - | Se si desidera che le notifiche per lo stato del servizio (warning o critical) vengano segnalate tramite email. Andare su **Advanced Settings** del host, ed inserire l' | ||

| - | # Plugin para chequeo de servidor tomcat para nagios | ||
| - | # Check tomcat server plugin for nagios | ||
| - | # This plugin uses the tomcat manager webapp, this app usually is located in the | ||

| - | # which " | ||
| - | # is the port number of the tomcat service (the tomcat port is 8080 by default) | ||
| - | # | ||
| - | # This plugin can check this items: | ||
| - | # 1- tomcat server status | ||
| - | # 2- tomcat server memory | ||
| - | # 3- tomcat server thread connectors | ||
| - | # 4- application status on tomcat server | ||

| - | Nagios core richiede 4 formati dello stesso file (gd2, png, jpg, gif). Usare icone 40x40 con sfondo trasparente. Ci sono diverse utility ed è stato realizzato anche uno script che dato come argomento un gif realizza la conversione negli altri formati. | ||
