Purpose

This module allows you to

• Keep track of a presence of a particular file (0 for file not present and 1 for file present)
• Size of a particular file

Install

Copy file_checks.py from python_modules to your python modules directory e.g.

/usr/lib64/ganglia/python_modules

and file_checks.pyconf to

/etc/ganglia/conf.d/

Restart Gmond and you are done.

Configure

Please see file_checks.py. Under metric_init you will need to add any metrics you want added e.g.

descriptors.append(create_desc(Desc_Skel, {
"name"       : NAME_PREFIX + "etc_chef_disabled_present",
"call_back"   : get_is_file_present,
"description" : "/etc/chef/disabled present"
}))

Replace slashes (/) with underscores and drop initial slash and append _present. For file sizes add following segment

descriptors.append(create_desc(Desc_Skel, {
  "name"       : NAME_PREFIX + "var_log_syslog_size",
  "call_back"   : get_file_size,
  "units"       : "bytes",
  "value_type"  : "float",
  "description" : "Size of /var/log/syslog"
  }))

Append _size to the metric name
