The NRPE server that runs on remote monitored machines does require quite a few additional packages to be installed (see below for in-exhaustive list), and if you are concerned you try the alternative approach of getting data back from your remote server via SNMP as described in this example [[#Ubuntu_Software_Updates_Monitor|Ubuntu Software Updates Monitor]]. This can make for a more lightweight solution, but will require you to write your own monitoring scripts to be called by the SNMP daemon. Swings and roundabouts. | The NRPE server that runs on remote monitored machines does require quite a few additional packages to be installed (see below for in-exhaustive list), and if you are concerned you try the alternative approach of getting data back from your remote server via SNMP as described in this example [[#Ubuntu_Software_Updates_Monitor|Ubuntu Software Updates Monitor]].
