smb.monitor is a script for use with the mon package. It simply connects to a host and lists the shares to detect failures from name resolution or authentication.

Installation

To install the script simply download it to the mon scriptdir, usually set to '/usr/local/lib/mon/mon.d:/usr/lib/mon/mon.d'. Then add the settings for this to the mon.cf file.

Configuration

It configures like any other mon script, the specific parameters are -p and -u for password and username. A sample is provided below.

hostgroup smb_devices 192.168.42.2 192.168.42.22 192.168.42.222

watch smb_devices
  service smb
    interval 1m
    monitor smb.monitor -p secret -u jsmith
    period all_the_time: wd {Sun-Sat}
      alertafter 3 10m
      alert mail.alert someone@somewhere.tld
